"Case to answer" on neonicotinoids and bees Posted by Laura Rayner (http://www.alynsmith.eu/lerayner) 54.80pc on February 20, 2013 · Flag (http://www.alynsmith.eu/forms/flags/page.js?page_id=267)


Alyn Smith MEP, Scottish member of the European Parliament's Agriculture and Rural Development Committee, has today (Wednesday) called for greater research into the impact of neonicotinoid pesticides on bees and lambasted some colleagues for swallowing lobbying propaganda and using scientific doubt as an excuse for inaction.
The call came in a packed committee meeting in Brussels, attended by European Commissioner for Health and Consumer Safety, Tonio Borg.

The meeting heard a presentation from the European Food Safety Agency (EFSA) on their study into the the risks to bees from neonicotinoids, acknowledging that there are threats to pollinators from these chemicals, though highlighting gaps in the evidence and that there remains some scientific dispute over the technical issues.

Alyn said:

"There are two bad lines of argument used on this issue. On the one hand, 'we need more data before we act' could keep us in stasis for a million years, but on the other, the 'precautionary principle' could be used as justification for not getting out of bed in the morning!
"It is up to us as legislators to make a call on the balance of the evidence available proportionate to the scale of the risks involved, and I've been concerned to see some MEPs parroting what is in effect lobbying propaganda as if it were gospel handed down on tablets of stone.

"I have been saying this for some time: the worrying decline in bee numbers is, at least in part, caused by toxic chemicals sprayed on our fields. I simply do not see how any other conclusion is possible based on the evidence available, not least after the EFSA study found clear links between the use of the chemicals and damage to bees.

"I back the European Commission's proposals for a partial ban on the most risky uses of these chemicals, but I also want to see a lot more research and if we're proven to be over-cautious then we can relax the ban.

"The potential consequences for agriculture, food and humankind of a continuing collapse in pollinators are stark. In any objective discussion there is always room for doubt but the more credible data is clear, there is a case to answer and there is a need to act."

There was an article in the Dundee Courier last week that discussed the disagreement between Alyn Smith and George Lyon, both MEPs whom I've met in recent months. Perhaps I should add that we didn't discuss bees or pesticides, just potatoes. They were presented in the article as taking opposite sides in this debate. I can't find the Courier article online, but George Lyon's position is described here:

http://www.farmersguardian.com/home/arable/push-to-overturn-potential-neonicotinoids-ban/53540.article

Here is an excerpt. I perfectly agree. The available science does point to very low residues from winter OSR at a level that seems unlikely to cause harm.

At a meeting of the EU Agriculture Committee on Wednesday, Commissioner Tonio Borg said one option being considered was exempting winter sown crops from any ban.


George Lyon MEP said any flexibility on the proposed neonicotinoid ban was ‘a step in the right direction’.


Mr Lyon said: “Exempting winter sown crops would give Scottish farmers a real boost. A limited ban would reflect the science more accurately and ensure that farmers are not being penalised on a selective reading of the available evidence.

Well, not all MEPs and MPs have got the right attitude yet. :rolleyes:

To help your MP to express his support for our bees and pollinators, get him to sign the Friends of the Earth Action Plan for Bees:

http://www.foe.co.uk/what_we_do/the_bee_cause_35033.html#

Check if he is on this list first, he might have signed up already. If not, send him a quick note with the link!

Bee scare buzzes into Tweeddale

David Knox (http://www.sbai.org.uk/search/dknox/)• Published 9 Mar 2013 07:00


A STUDY into the survival of struggling honey bees has found the Tweed Valley is amongst the worst for mortality rates. The research by the University of Dundee has prompted for greater action to tackle the decline of the species.
The science team, with help from members of the Scottish Beekeepers Association, studied more than 600 colonies across the country in 2011/12.

Of 274 colonies examined in the east of the country, 58, or 21 per cent, failed.
By contrast, just 14 of 286 colonies failed in the west, a smaller decline of about five per cent.

But more worrying, locally, is that the Tweed Valley population was decimated by just under 20 per cent - one of the worst hit areas in the country.
Scientists believe the presence of intensive agriculture and large areas of oilseed rape in the east could be linked to the poorer results for the area.

And they criticised the lack of data available regarding pesticides used by farmers.

Dr Christopher Connolly, who led the research, said he was stunned by the findings. He told the Peeblesshire News: "What we do have in the east and not the west is intensive agriculture.
...
Anecdotal evidence also suggests that similar devastating losses were experienced the previous year.
However, even within the east, there were marked differences in death rates. Colony losses in parts of Fife were recorded as high as 30 per cent and the Peeblesshire figure stood at 19 per cent.
...
A further study led by Dr Connolly analysed colony failure rates over winter across the country.
Of 89 colonies which had fed on oilseed rape, 27 failed, a death rate of 30 per cent.
...
Dr Connolly believes that nicotine-based pesticides, neonicotinoids, may be contributing to the deaths of bees feeding on the crop.
He added: "All oilseed rape is treated with neonicotinoids, you can't buy it without it being pre-treated with neonicotinoids."

Dr Connolly is now demanding the centralised recording of data so that the "multiple threats" to bees can be analysed properly.
And he wants the Scottish Government to take action to address the issue.

Just out of interest and this is a serious question - how did Dr Connolly demarcate the division between east and west? It seems a terrible generalisation to equate east with intensive agriculture and west with the absence of that. For example where I live would generally be thought of as "east" and there's not an OSR field within 15 miles of me.

And of course it's been said a million times before. Were any of those dead outs tested for pesticide residues? If not you'd be as accurate in saying they died from excessive exposure to oxygen.

And what do the 30 studies have to say about the specific colonies referred to by Dr Connolly? My point is - how can you say "it was Neonics" when those colonies haven't been tested for them? As well to say that the east of Scotland has a preponderance of beginning beekeepers who don't know how to get their colonies through a winter.

No answer to specific questions Doris? You don't change do you?

I had to go out, I have no problem explaining why there are not enough analysis done that prove the neonic connection.

For a start, most beekeepers are thoroughly misinformed about CCD and other signs of neonic damage.
They are told that their colonies dwindle away for all sorts of reasons, so they never even think of having an analysis done.

Secondly, the National Bee Unit only asks for bees for sampling if poisoning is suspected.
Most hives that die from neonics have hardly any bees left that could be tested. A much better way of finding neonics is by testing wax and propolis from the hive, but nobody tells that to the ordinary beekeeper.

It looks like the NBU doesn't want to find samples positive for neonics.

:(

drumgerry
09-03-2013, 08:20 PM
You're still not really answering the question.

Dr Connolly implies that his 21% dead colonies from the east (still no proper definition of where that is) as against 5% from the west is down to intensive agriculture and by association neonics. My specific question is how can that be said when as far as I know there has been no pesticide analysis done of those colonies? It is therefore pure speculation what the causes of death of those colonies are. Speculation which fits your agenda but speculation nonetheless.

Maybe my example of over-exposure to oxygen as an equally valid reason for their deaths was a flippant one but it made the point that in the absence of any proof any cause can be made to fit

drumgerry
09-03-2013, 08:35 PM
And another thing -

You said:
Most hives that die from neonics have hardly any bees left that could be tested.

If this is the case (although I have my doubts) was it the case that the colonies in Dr Connolly's research were left with few bees in the hive? If this is a diagnostic feature of neonic death was it present in most of the colony deaths recorded in the "east"? If not maybe it wasn't neonics at all. Maybe it was varroa or varroa-vectored viruses. Or isolation starvation or any number of ordinary causes for colony death.

Stromnessbees
09-03-2013, 09:57 PM
Wherever Colony Collapse Disorder (CCD) has turned up, it was in conjunction with the use of neonics, usually in agricultural areas, but sometimes near orchards, golf courses or parks which were treated with these pesticides.
I know that there's a small army of people out there that try to confuse this basic fact, but I think I know where they come from.

I don't know Dr. Connolly's data in detail so I can't answer your questions.
Why don't you send him an email and ask him.
I have full confidence in his assessment of the situation, and it fits in with all the other independent research that has been published on the topic.

As for the studies financed by Bayer, well they seem to come to different conclusions, but they are by far in the minority.

drumgerry
09-03-2013, 10:11 PM
You don't know Dr Connolly's data in detail yet you're happy to quote it where it supports your position that CCD = neonic poisoning. My view of what he has published is that the conclusions it comes to are seriously flawed. We could endlessly go around the houses and I could give you a platform to repeat what you've repeated ad nauseam on every beekeeping forum known to man which hasn't banned you yet but I don't think I will.

You say there's an army of people out there confusing the "basic fact" about neonics and you know where they're coming from. Where is that Doris? Isn't it the case that you believe that anyone who questions your position on neonics is in the pay of the pesticide companies? Isn't it the case that you believe that the main UK beekeeping forums are run by people in the pay of the pesticide companies?

Well, Dr Connolly, to be speaking to the Parliamentary Environmental Audit Committee, the Beeb, the Scotsman, and the Peebleshire News on this, his chosen subject, will surely have checked his facts first? Is it true that there is no recording of data on pesticide use across Scotland? Or is it just OK to make stuff up because it sounds good?

OK Doris, did Dr Connolly record the experience levels of the people responding? If not, why not?

Did Dr Connolly record the levels of Varroa in the surveyed colonies, ideally in autumn? If not, and considering the evidence from most studies of colony losses elsewhere that this is always the big one, why not?

Did he record the strength of colonies going into winter and the levels of stores in the colonies?

By now the pesticide corporations are in charge of all the major beekeeping forums, akin to foxes running the hen house.

Our freedom of speech has been taken away, the most important discussions moved behind closed doors or severely censored.

Winter dwindle has been reported for centuries though, before CCD, before neonicotinoids, before any pesticides for that matter.
It can be caused by varroa mite, tracheal mite, nosema apis, nosema ceranae, queen failure, inbreeding, weather related factors, poor nutrition in the build up to winter, and/or virus. take your pick.

Claiming that most cases of dwindle we see today are CCD is a tad disingenuous to say the least when there is nothing more than a personal opinion proffered - and diagnosis is carried out over the internet in most cases.

Even in the US where CCD has actually been recorded many cases of dwindle are likely to have other explanations.

CCD has been found in areas of pesticide use and in areas with little or no pesticide use such as Dee Lusby's 'organic' beekeeping operation in the Southern US.

Noone has demonstrated any correlation between areas where neonicotinoids are used and areas where CCD occurs.
In fact, there appears to be no correlation at all.
That's not to say there are no dangers associated with neonicotinoid pesticides - clearly there are risks, but there is no correlation at all with CCD.

The colony collapse disorder (CCD) has been reported in areas where intensive agricultural practices constitute the main economic activity. Particularly in Uruguay, continuous beehives losses were recorded since 2002. After this first event, a monitoring program has been established showing that the major losses occurred in regions where soy and sunflower crops are the most important agricultural activities during summer

No, sudden winter dwindle of previously strong colonies is a new phenomenon.

The affected American beekeepers certainly said, that they had never seen anything like it before.
That's why CCD caused such an outcry.

I would encourage all beekeepers who have had sudden dwindling in their colonies this winter to contact me by pm.

What do you mean by sudden dwindle? Over what time period?

Are there no references correlating CCD with neonicotinoid use in the US? Surely that would be more obvious given that the US is where most cases of CCD have been reported.

It would be the easiest thing in the world to demonstrate given that we know geographically where cases of CCD occur and geographically where pesticides are applied.
There is no correlation.

Interesting Doris. I know nothing about soy, but have just dug out a Swiss paper on sunflowers.The summary states:

"Influence of sunflower crops on bee colonies development.
In Switzerland, sunflower cultivation extends since the nineties and nowadays reaches
about 5000 ha. The sunflower seeds are not treated with insecticides (imidacloprid,
fipronil) but despite that, Swiss beekeepers are complaining about colony losses if the
hives are placed close enough to fields of blooming sunflower. A two-years trial was
carried out in order to find out whether sunflower by itself was detrimental for bees or
caused any colony damages. Results show that foraging of sunflower has no adverse
effect on bee populations neither during blooming period or within the next following
months. Sunflowers didn’t have any impact on bee losses during winter. Bees were foraging
intensively on sunflowers but the nectar quantity collected was small or nought.
During a few days after the migration to the sunflower fields, bees were collecting
sunflower pollen but opted soon for other pollen sources such as maize and clover."

But I'm going off subject.

How does a table showing states with CCD reported in 2006 demonstrate a correlation with current use of neonicotinoids? That's just a list of states where CCD was reported in 2006.
How would you separate out any correlation between CCD and monoculture or intensive agriculture as opposed to an association with neonicotinoids.

This was also the problem with the Connolly study. A whole stack of other variables which were not eliminated.


The sunflower seeds are not treated with insecticides (imidacloprid,
fipronil) but despite that, Swiss beekeepers are complaining about colony losses if the

I was at a presentation on Friday evening by Pam Hunter on the importance of pollen and she mentioned that bees which took pollen from sunflowers lived on average 31 days as opposed to 51 days for bees on other sources of pollen. I don't have a reference but will do a bit of googling.

EDIT.
This must be where she got the reference (http://www.beeculture.com/storycms/index.cfm?cat=Story&recordID=628).
L.S.Schmidt et al, Feeding preference and survival of young worker honey bees fed rape, sesame and sunflower pollen. J. of Econ. Entom. 88(6):1591-1595 (1995).


1995 study4 divided bees into two groups: one fed solely with canola pollen, the other with sunflower pollen:

Pollen Source Life Span of Bees

Canola 51 days

Sunflower 31 days

This study was done well before the advent of CCD and the remarkable 20 day difference in life span could well cause sunflower bees that survived in past years to reach a tipping point in today’s world where they are confronted with the agents of CCD.

From the USDA (http://www.ars.usda.gov/News/docs.htm?docid=15572)

Colony Collapse Disorder (CCD) is a serious problem threatening the health of honey bees and the economic stability of commercial beekeeping and pollination operations in the United States. Despite a number of claims in the general and scientific media, a cause or causes of CCD have not been identified by researchers.


Several studies that reported a negative impact on honey bees by neonicotinoids relied on large, unrealistic doses and gave bees no other choice for pollen, and therefore did not reflect risk to honey bees under real world conditions. Nor have the studies demonstrated a direct connection or correlation to CCD.

At a personal level, a few years ago I had a double brood colony crash from maybe 40,000 bees to 2 frames of bees in about 3 weeks. It had got to the brink of starvation and although it took down a lot of syrup the stress brought on (I suspect) nosema.

In the winter it is not unusual at all to have a small colony crash from 3 frames of bees to a little cluster of a couple of hundred over a 3 week period. This coincides with the die off of old bees. This is quite common and always had been but it is not CCD. I have lost several nucs like this this winter. No mystery at all.

Well, it says it clearly there: in sthe sudy they used no insecticides and there were no adverse effects.

I thought you were trying to say the opposite.

Maybe the fields that the beekeepers complained about had actually been treated.

Just been reading the March 2013 issue of the ABJ where there is a report on the findings by Henderson, Bromenshenk and Fischer on Clothiandin levels in bee-collected pollen and nectar in seed treated corn and canola/OSR - tests carried out during 2010 and 2011.

Seed treatment was at the standard levels used in agriculture in the US (0.5mg/seed) up to the maximum permitted level (1.25mg/seed). In corn the mean level found was 1.2ppb and in canola the mean level was 2ppb or less. Levels, they say, not expected to pose a significant risk to honey bee colonies. I think you'll have to look elsewhere for your smoking gun when it come to CCD Doris.

So states with no or limited commercial, migratory beekeeping aren't reporting CCD is the main conclusion I draw from that table.

Our bees have no access to commercial crops so no access to neonics, nor do they have varroa. I have had a huge, prosperous colony collapse completely in a matter of a couple of weeks due to acarine. This was last autumn.

I also lost a complete colony this November (double brood, four full supers for three summers in a row - unusual for here) due to unsuccessful supersedure in August. I can blame an extra-long autumn holiday and weather on return too poor for proper inspection of brood boxes for this mishap. However, claiming CCD might cover up what was, in essence, poor beekeeping on my part. I read the signs, understood the signs, but was just too busy with other things to do anything about it.

Jon
10-03-2013, 09:26 PM
In post 29 I listed about 10 factors which are known to cause dwindle or collapse, sometimes quite quickly.
Calling any dwindle or collapse CCD without clear evidence makes no sense especially as these things have been happening for decades before neonicotinoids were around.

It should be the easiest thing in the world to demonstrate.

Neoticotinoids used in an area = possibility of CCD in that area.
No neonicotinoids used in an area = no possibility of CCD

Yet we get neonicotinoid areas without CCD and neonicotinoid free areas with CCD present. I cited Dee Lusby's organic operation earlier.

Australia uses neonicotinoids and does not have CCD.
Australia has no varroa though.

What is happening here is that Doris is using dwindle as a synonym of CCD and that is not a valid position to take imho.

Just been reading the March 2013 issue of the ABJ where there is a report on the findings by Henderson, Bromenshenk and Fischer on Clothiandin levels in bee-collected pollen and nectar in seed treated corn and canola/OSR - tests carried out during 2010 and 2011.



Unfortunately Mr. Bromenshenk is one of those scientist who has taken the pesticide industry's shilling, and worse, he forgot to mention it when he went public with his research:


What a scientist didn't tell the New York Times about his study on bee deaths

...
What the Times article did not explore -- nor did the study disclose -- was the relationship between the study's lead author, Montana bee researcher Dr. Jerry Bromenshenk, and Bayer Crop Science. In recent years Bromenshenk has received a significant research grant from Bayer to study bee pollination. Indeed, before receiving the Bayer funding, Bromenshenk was lined up on the opposite side: He had signed on to serve as an expert witness for beekeepers who brought a class-action lawsuit against Bayer in 2003. He then dropped out and received the grant.

Bromenshenk's company, Bee Alert Technology, which is developing hand-held acoustic scanners that use sound to detect various bee ailments, will profit more from a finding that disease, and not pesticides, is harming bees. Two years ago Bromenshenk acknowledged as much to me when I was reporting on the possible neonicotinoid/CCD connection for Conde Nast Portfolio magazine, which folded before I completed my reporting.

That was an appalling smear and one I've said repeatedly I hope ended in court with the journalist responsible brought to account. Jerry had a small contract with a breeding company with was subsequently bought by Bayer as I understand it.

Bromenshenk obviously chose not to go for litigation as the claims of failure to disclose were correct.

In his research he 'discovered' that some iridovirus was behind CCD, a claim which couldn't be verified by anybody else and the idea was soon dropped.

I have no idea how he came to his conclusions.

I don't think the iridovirus is likely to have much to do with CCD either as subsequent research found problems with his methodology but that is no excuse to start the smears against people who hold views different from your own.

If you want to debate the issue you need to leave behind the smears and the conspiracy.
Biobees welcomes conspiracy according to the site owner so maybe you could save it for that audience many of whom are quite happy to listen to unsubstantiated claims. Most places have a requirement for evidence.

If you want to convince people you have to put together a cogent argument rather than resorting to abuse.

Hi
my 0,02€ my losses this year were 1 from 27. I am situated right in the middle of a intensly farmed area, that includes plenty of treated maise.
My beekeeper next door lost 20 from 40 colonies. He taught me how to beekeep. The differences in losses are clearly not statistically correlatable. So it is not something caused by the environemt, but caused by something we have done differently. So far the only difference we could find is that he started varroa treatment a week later.

Doris, pesticides are not great, but the ones today are better than many from yesteryear, you would get your point far better across if you were less hysterical about it. Daten Fakten Zahlen. Data, facts, numbers.

gavin
11-03-2013, 09:28 AM
Getting back on topic:
Gavin, I hear you had some colony losses yourself this winter.

Would you mind telling us what exactly happened, your varroa control, proximity to neonic treated OSR, etc? - After all you are in the East, which was significantly harder hit with colony losses this winter.

Doris, I don't see why my winter losses are 'on topic' in a thread about one Scottish MEP joining the anti-neonic bandwagon. However ....

Seven colonies of viable size (6-12 frames bees) going into winter, at the moment six are bringing in pollen and one is pushing up daisies. That one had declining strength early in the winter. A queen problem seems likely given the atrocious queen mating weather we had here with, as far as I recall, only one iffy three-day weather window to let them get airborne.

One further small colony rescued from a friend. Serious Varroa problem and after treatment it was down to two frames of bees, not a viable size for winter. It was the first to go. My own Varroa control was winter oxalic and summer Apiguard and number were fairly low through the summer. OSR is in the arable land around the estate where I keep my bees and bees accessed it on the better days in May. In previous years they have had better weather in May and have made better use of it - and thrived on it.

See any neonic issues there? I don't.

The association's bees? Again we had dreadful queen mating. The stronger colonies going into winter were fine, and the small nucs which were always going to be a big risk have had some losses.

All colonies behaved normally when the OSR was flowering.

The story is that if you are on top of Varroa and if you feed your bees at critical times when they need it, losses are low. A bit higher than low when the previous season's queen mating was poor. If you are not alert to the problems through the active season, you lose more colonies. If you give poor advice on controlling Varroa to the beekeepers in an area, you get higher losses locally. If you live in a Varroa-free area, your losses are generally lower. If you gather up inexperienced volunteers in an area where people are being given poor advice on controlling Varroa, you record higher losses there.

Hi Doris. I am having difficulty sifting through this stuff.
On the one hand you say you changed your views on CCD since 2010 as you had 'just got back into beekeeping'. Elsewhere you describe yourself as a 'very experienced' beekeeper. You also claim to have seen CCD 'repeatedly'.
You live on an Island with no varroa mite and presumably no CCD.
I imagine there is little or no neonicotinoid use apart from a minimal amount used in garden products or for killing the fleas on the dog.
There seems to be a contradiction here.
Are you actually aware of the patterns of colony losses associated with varroa and have you got years of experience quantifying mite levels, virus levels, percentage of infected pupae, living with varroa through the 12 months of the bee season, treating varroa at key times and selecting the most appropriate treatment?
The pictures you post from time to time just look like classic varroa death colonies for the most part.
Same goes for the you tube links you highlight from time to time.
Even in the US the vast majority of colony losses do not fit the pattern of CCD.

If you set yourself up as a leader and interpreter of data you really do need the experience to back it up.
Maybe you have the experience but it is not clear where and when you might have picked it up.
How many years have you actually managed colonies of bees with a mite population on an ongoing basis?
I thought you had lived in Orkney for about 20 years.

Don't worry, I have plenty of beekeeping experience with varroa and without.

I started keeping bees when I turned 20 while I studied Biology in Austria. I attended courses and met regularly with the local beekeepers for joined sessions.
Varroa was already widespread, but those who treated for it had no problem and It was only very neglected colonies that would be lost to it, always a very obvious affair with varroa all over the bees and brood as well as deformed wings on a proportion of the bees.

I kept an average of 6 to 8 hives for 6 years and never lost a colony to a disease.
Neither did the other beekeepers around me who looked after their hives.

After moving to Orkney I was given a varroa free colony which thrived more or less on its own for many years, but I moved from one island to another and had to leave it behind.

Later I joined Bees Abroad and traveled to Africa several times, helping the local population to set up sustainable beekeeping projects.
Btw, I found varroa mites in Ghana, but the bees there were still thriving despite them.

In the end I decided to get bees again at home.

After I started again in Stromness, I joined the internet beekeeping community.
Here I found a completely different world of beekeepers which is very divided, and the ones that are most active online are representing opinions that I had never experienced from beekeepers before, like defending the use of a particular group of pesticides and defending GMOs.

Not being a luddite I have treated sheep, dogs and horses with the odd wormer when it seemed necessary.
So I got on with learning all about the British and American way of keeping bees, ignoring the pesticide issue initially, visiting beekeeping friends around the country and looking at hives with them. I noticed the strange problems they had down in England, but I had no answers.

But a visit to Austria, where an apiary that was only a stone-throw from where my own one had been, was wiped out completely, made me research the topic thoroughly.

Everything there was still the way it had always been, but the bees had disappeared, and left a picture of classic CCD behind, with small dead clusters including queen amongst plenty of stores, some colonies with remnants of brood and some without.

The only change had been that the maize that was routinely grown in small fields in the area was now treated with Clothianidin.

This was leftover seed that had been sold over the border from Germany, where it had been banned after causing massive colony losses there.

I gave at talk at a beekeepers' convention and met many other experienced beekeepers who had lost their apiaries as well at the same time and under the same circumstances.


Now that I was more familiar with the topic I realized, that ailing colonies which I had seen at apiaries in England were suffering form the same problem, although the damage from Imidacloprid seemed less severe than the one form Clothianidin, showing itself more in queen problems and colonies stopping to feed at the end of winter, leading to partial apiary losses.


Here in Orkney bees thrive but produce little honey due to the harsh climate.
We don't have varroa, we don't have CCD or 'dwindling disease' and we don't have neonicotinoids in the forage.
As I explained, I know how to check for varroa damage, and the CCD colonies I saw clearly looked very different from that.
A 'dwindling disease' without obvious other signs had not been recorded before, and I am convinced that the term is used to mask losses to neonics.

Jon
11-03-2013, 12:17 PM
Hi Doris
But seriously, a small cluster with a queen in it can have many different explanations such as those I mentioned in post 29 and is not necessarily CCD even in the US.
I think you are underestimating the problems with varroa and more especially the viruses associated with it which are not the same as 20 years ago. The virus landscape changes all the time.
The Martin et al paper we discussed last year describes how the strains of DWV change after the arrival of varroa mite.
It really is quite a common thing to find a colony which has dwindled in springtime.
Classic CCD is usually associated with autumn dwindle.
The pictures and videos you have posted here and elsewhere seem to me to show colonies with varroa damage.
And that's not just my opinion. They generated the same response on Beekeeping forum and on Beesource.


Here I found a completely different world of beekeepers which is very divided, and the ones that are most active online are representing opinions that I had never experienced from beekeepers before, like defending the use of a particular group of pesticides and defending GMOs.

Yes there is division over what is best for bees but there is no bad faith here, no conspiracy, no lobby, no shills involved. What you have is people who want the best for their bees and this involves real world choices which translates to the use of one pesticide over another. I would prefer a non pesticide solution to modern agriculture but I don't see where that can come from in the short to medium term.

If neonicotinoid pesticides are banned, I do not think that would necessarily improve the wellbeing of honeybees, as my personal opinion is that the greater problem is to do with habitat, forage and monoculture and monoculture is likely to continue with or without neonicotinoid pesticides.
Most likely there will be no real change as that seems to be what has happened elsewhere when these products have been withdrawn.
The potential loss of Oil Seed Rape will be very detrimental to bees if farmers elect to grow alternate crops.
Bees forage on seed treated oil seed rape over millions of hectares world wide and beekeepers are still moving their bees to it and they don't report problems. Quite the opposite. The problem with this crop is during seed drilling with poor control of the planter dust.

I would like to see neonicotinoids, and any pesticides in fact, very strictly monitored and regulated.
I think we can all agree there are gaps to be filled especially with regard to the effect on pollinators other than honeybees.

I know that in my hometown the first occurrences of CCD happened in the winter after the introduction of Clothianidin treated maize.

It would be a very strange coincidence if a virus had spread at the very same time, wiping out so many colonies, all in proximity to the neonic treated maize fields.


I encourage all beekeepers who have lost hives to 'dwindling' to talk to their beekeeping neighbours about it and to check for possible sources of neonics in crops, orchards, parks and golf courses nearby.

To test a colony you need to send wax (ideally cappings from leftover food), pollen and propolis rather than bees, as this increases the chance of detection.
Keep the samples in the dark, as the pesticides deteriorate in sunlight.

Jon
11-03-2013, 01:08 PM
That's a good idea as without proper checking it is just so much speculation.

Mind you the situation in Austria is reported to be much better this winter even though Clothianidin is still in use.
You get a lot of year on year differences in beekeeping as there are so many variables in play.

Yes, I heard the slight improvement came from farmers choosing untreated maize seed last year in order to help the bees.

Hi Doris,
I never heard that, whats your source of information?
Also if true it should cause a massive improvement I'd have thought (assuming thats the prime problem).
However the reported reductions in insect numbers overall is worrying. This is certainly affected by the reduction in biodiversity, changing weather patterns and pollution (which almost certainly includes pesticides).

Hi Doris,
I This is certainly affected by the reduction in biodiversity, changing weather patterns and pollution (which almost certainly includes pesticides).

Also affecting birds: specifically sparrows.. Lack of food for young. And lack of suitable nesting habitat. Allegedly (BBC Gardening Mag read in library) there are more sparrows around in the less well off places in towns and cities due to neglected areas having more nesting places and vegetation suitable for insects.

Believeable as many people use decking and preserve it every year ... and use bought plants -often double flowers.. and strim and cut grass to death.


We always have a wonderful display of midges in evening - numbers increased markedly last year with the wet "summer". But then we border fields full of cows and have borders which are run as semi jungles with creeping flowering plants... and use no pesticides.. and have used none for over two decades...


(we also have 5 active colonies of sparrows in our eaves)...


If campaigners against neonics concentrating on persuading (NOTE: choice of word) gardeners to create insect friendly gardens and stopped magaphone posts on specialist websites where everyone is in favour of insect preservation...

I am in touch with several beekeepers in Austria, and I am a member of the German Beekeeping forum, which is very switched on about the matter.

As I say, there are some farmers who made an effort to use untreated seed, and in those areas the situation has somewhat improved, although it does take a while to get the toxins out of the soil system.

Btw, the total number of colony losses this winter has not been recorded yet, so we need to wait and see.

One reason for fewer losses might unfortunately be the fact, that many beekeepers who lost their whole apiary to these pesticides, decided not to restock and gave up, leaving empty beehouses all over the valley.

The reference I posted for you over on beesource indicated that Austria has had quite severe winter losses a couple of times recently without invoking neonicotinoid pesticides to explain it.


Heavy colony-losses during the winters 2002/2003 and 2003/2004, as well as bees showing unusual behaviour raised the question whether virus infections may be involved in these conditions.

Virus was implicated (http://www.ages.at/uploads/media/Prevalence_of_six_honey_bee_viruses_in_Austrian_be e_colonies_with_disease_symptoms_01.PDF) in these previous two die offs.

If a study looks only for viruses it will find only viruses, see the title:


Prevalence of six honey bee viruses in Austrian beecolonies with disease symptoms

They only took samples from dwindling hives, there's no comparison with healthy ones, which might have had just as many viruses.

With many bee stressors such as virus, nosema, poor nutrition, varroa, acarine, the end result is a small cluster and ultimately death, usually due to freezing or isolation starvation. I am not denying for a minute that pesticide poisoning can kill a colony but without access to the data all this stuff you are posting about neonicotinoids producing CCD is just pure speculation. A small cluster with a queen is not CCD. You are the only person defining it in that way.

That much is common knowledge and any beekeeper will have seen it many times.
Dwindle can happen any time of year but is much more common in winter as anything which compromises the longevity of the bees is likely to have serious consequences for the survival of the colony.
Winter bees have to live for 5 or 6 months unlike summer bees which are not expected to live much more than 6 weeks.
If they live for only 3 or 4 months on average the colony will shrink rapidly in January or February.
The most common form of winter deadout in my experience is a small cluster usually with a queen.
I have seen this over the years in my own bees when I have lost colonies over winter.
Normally it is only one or two.
The main exception would be a bigger colony which starved due to lack of stores.

Diseases: Honeybees and their larvae are affected by many diseases caused by bacteria, fungi and viruses. Research has shown a link between certain bee viruses, Varroa and colony decline. The mite can transmit some viruses within the colony and increase the rate of infection compared to hives that are mite-free. Some mite-transmitted viruses, such as deformed wing virus, acute paralysis virus, slow paralysis virus and cloudy wing virus, weaken honeybee colonies by reducing the longevity of adult honeybees.

The importance of preparing colonies to enter the winter in a healthy state, with an
adequate supply of young healthy bees and stores, cannot be over-emphasised.

a colony overwintered in good condition
ensures that it is fit for purpose in the following spring. Recent winter colony loss
investigations, both in the UK and across Europe, have clearly shown links
between dead colonies and the viruses, particularly deformed wing virus, which
are associated with varroa infestations. This highlights the importance of effective
and timely varroa control.

Capa statement on honey bee losses in canada (http://www.capabees.com/main/files/pdf/canwinloss.pdf)

For Canadian beekeepers experiencing the highest levels of loss, a number of common factors
were reported by extension professionals. A consistent theme, particularly on the prairies, was the
exceptionally cold and in many cases rainy weather during spring 2011 which contributed to
increased dwindling and loss of colonies that emerged from winter.

In this paper we briefly review the past
history of colony collapses that are reminiscent of the present situation.
The first published record of this disorder appeared in 1869.

And so on and so on. There are many references which link winter dwindle to multiple factors/stressors and most beekeepers will have seen this for themselves on occasion. I certainly have. May be different where there is no varroa and associated virus.

Acarine (http://www.countryrubes.com/images/Tracheal_mites_Acarine_Disease.pdf)


Symptoms of Infection
Acarine disease is a winter problem. The effects of the disease are seen in
early spring when the colony population consists of mainly older bees. It is
merely the old and heavily affected bees that are killed. Bee colonies rarely
show signs of infestation in summer or autumn. It is difficult to detect the
disease when the infestation is light or in its early stages. The symptoms of
heavy infestation include:
• Colonies die or have a dwindling population in late winter and spring.

Virus and dwindle (http://www.ibra.org.uk/articles/Virus-infections-and-winter-losses)


Apiculturists have recently been confronted with drastic and inexplicable winter losses of colonies, and virus infections may be involved. Here, we surveyed 337 Swiss honey bee colonies in the winter of 2005 and 2006 and categorized their health status as: 1. dead (= no or few live bees left); 2. weak (= dwindling, high mortality of adult bees); or 3. healthy (= normal overwintering colony). From each colony, pooled adult workers were analyzed for deformed wing virus (DWV), acute bee paralysis virus (ABPV), chronic bee paralysis virus (CBPV) and Kashmir bee virus(KBV). Neither KBV nor CBPV were found, but significantly higher ABPV and DWV infections were found in dead vs. weak vs. healthy colonies (except DWV in 2006 between weak and healthy). Moreover, ABPV and DWV loads were positively correlated with each other. This is the first report demonstrating statistically significant correlations between viruses associated with Varroa destructor and winter mortality.

EPA view (http://www.epa.gov/pesticides/about/intheworks/honeybee.htm) on CCD (Includes mention of pesticides)


Why it's happening

There have been many theories about the cause of CCD, but the researchers who are leading the effort to find out why are now focused on these factors:

increased losses due to the invasive varroa mite (a pest of honeybees);
new or emerging diseases such as Israeli Acute Paralysis virus and the gut parasite Nosema;
pesticide poisoning through exposure to pesticides applied to crops or for in-hive insect or mite control;
bee management stress;
foraging habitat modification
inadequate forage/poor nutrition and
potential immune-suppressing stress on bees caused by one or a combination of factors identified above.

Additional factors may include poor nutrition, drought, and migratory stress brought about by the increased need to move bee colonies long distances to provide pollination services.

Jon, your first two quotes make no mention of sudden dwindling and tiny clusters.

The third quote is very recent and those incidents might well have been linked to neonics!

No. four: to vaguely quote bee deaths in the past doesn't mean that they showed sudden dwindling and tiny clusters.


A simple statement form a decent source that's more than 20 years old (pre neonic), which mentions 'sudden dwindling in winter' and 'tiny cluster' is what we are looking for.

Jon
13-03-2013, 12:57 AM
Anything which compromises longevity produces a tiny cluster.

Check out the symptoms of acarine (trachael mite) in the link above.

The Swiss study categorised colonies in the study as 'dead' 'dwindle' or 'healthy'.

Seriously Doris, what you are calling CCD is simple winter Dwindle. It may be linked to pesticides in some cases, I don't dispute that, but it is not a new phenomenon. The Americans have a different definition of CCD and it is more than just dwindle and is more usually an autumn problem than a spring dwindle problem.

Stromnessbees
13-03-2013, 12:58 AM
You added more ...

@ quote 5, acarine:

your quote was very selective, the full text says


The symptoms of heavy infestation include:

• Colonies die or have a dwindling population in late winter and spring.


• In cases of severe infestation, a large number of bees crawl about near the entrance of the hive unable to fly. This is seen when they attempt to fly when a warm day comes in late winter or early spring after the bees have been confined to the hive for a long time.



• Bees with acarine mite infestation may have one hind wing sticking out at right angle from the body.


• Acarine infection can be suspected if there is a large number of dead bees in the winter and there is enough honey in the hive. Acarine mites are undetectable with the naked eye.


The only certain way to detect mite infestation is to examine bees for the mite’s presence using a binocular dissecting microscope or higher power hand lens. The thorax of

suspected bees can be opened to expose the main tracheae where the mite is commonly found.



Acarine is very different from CCD, as you can see when you read all the bits which you omitted from the quote.

And surely all these bee experts with their microscopes would have found the mites.

Wilson, WT, and DM Menapace (1979) Disappearing disease of honey bees: A survey of the United States. ABJ March 1979: 184-186.


“In the case of [Disappearing Disease]… the colonies frequently have gone through a period of nectar and pollen collection with active brood rearing. Then the weather has turned unseasonably cool and damp and remained adverse for from about 3 to 14 days. Such a situation usually occurs in early spring. During the inclement weather, the bee populations dwindle because the worker bees disappear from the hive leaving a “handful” of bees and the queen.”

The point is, there are multiple explanations for finding a small clump of bees with a queen in it during springtime.
Pesticide poisoning could be one of them but to claim this is the only cause and to claim that this is 'CCD' is not accurate.

Seriously, Jonathan, everybody who has seen CCD agrees that they have never seen anything like it before, for example:



There are no bee bodies; they simply all disappear, all adult bees are simply gone, sometimes leaving a queen and a few young hatched workers. This is unheard of, since normally a bee colony will do almost anything to protect its queen.


The hive is left intact, with capped cells of honey and bee bread.


Another unusual factor is that bees sensing a dying colony nearby aren’t going in right away and killing the other bees and robbing the hive of honey, like they usually do for example when the bees have died of parasites or disease.


- Researchers have also noted few signs of damage from wax moths and small hive beetles taking advantage of dead colonies.


According to David Tarpy, a bee specialist at NC State, “Bees die all the time, although this year seems to be worse than normal.” The difference now is that none of the “usual suspects” are to blame, Tarpy said. “That’s what makes it problematic.” Also, unlike when bees are killed by some other causes (disease, mites), there are no dead bees littering the bottom of a hive. The bees are simply gone, he said, or perhaps a queen and a few younger bees remain, but the adults have disappeared.

This is a bit more like it, but doesn't apply to all the colonies lost during winter, which is typical for CCD.


I might look into this report some day, as I suspect that these events were related to some chemicals as well.

I know for sure that where I lived in Austria it was completely unheard of, and that CCD appeared suddenly just after the introduction of clothianidin treated maize.

And if you look carefully in other areas, you will find very similar stories.

Here's a beautiful film from Japan, for example, which tells the same story:

I have only ever seen this sudden leaving the hive and all its contents once... I was called about a "swarm" last summer which was massive and uncooperative :)
A more experienced beekeeper was called in and it turned out that the colony had up and left everything from a nearby hive

Here's why: upon giving the bees it was evident that varroa where all over the bees, their reaction to the extent of the mite numbers was to flee

Good thing was now that they were broodless they could be treated and give them a chance of survival.

I am in touch with several beekeepers in Austria, and I am a member of the German Beekeeping forum, which is very switched on about the matter.
A quick check of Landlive shows its not a hot topic at all. This is the most used site, what site are you referring to?


As I say, there are some farmers who made an effort to use untreated seed, and in those areas the situation has somewhat improved, although it does take a while to get the toxins out of the soil system.
Any proof of that at all, or just anecdotal?


One reason for fewer losses might unfortunately be the fact, that many beekeepers who lost their whole apiary to these pesticides, decided not to restock and gave up, leaving empty beehouses all over the valley.
:(

Funny you mention that, our Fachwart for Bees in Bavaria is sure that people who are not able to keep their bees healthy are indeed giving up in frustration, those that keep their varroa under control remain and prosper. Natural selection of beekeepers. Your assertation that the loose their whole stock to pesticides is not supported by any data.

Pesticides: the best excuse for colony loss due to poor beekeeping practice since forever.

If you look at the beekeeping density (in our area of Lindau Stadt we have over 50 with more than 1000 colonies) and the patterns of loss (most loose less than 10% some few 50%) there cannot be poisoning going on.... This pattern repeats its self in most beekeeping clubs.

The percent reduction year on year in colony loss is probably much more to do with improved training of how to deal with Varroa and bad methods dying out with their beekeepers giving up.

brothermoo
13-03-2013, 10:03 AM
Ps. Pesticides prob are factor across the world but irresponsible beekeeping is probably more of a factor.

things like:
-moving colonies up and down the country to different crops spreading different disease hasn't worked for the yanks
-not usi.g some form of treatment to diminish varroa
-importing foreign stock laced with new viruses for varroa to vector

Landlive is mainly for gardening and the green wellie brigade.

The big beekeeping forum is called Imkerforum, you will find lots of threads about neonics there, many going into hundreds of posts.

Here one of the latest: http://www.imkerforum.de/showthread.php?t=32607


If beekeeper failure is the main reason for losses, how can you explain that one of the UK's most prominent beekeepers, Roger Patterson, who teaches and lectures up and down the country, has lost half of his colonies this winter?

And I also remember that the guy who taught you lost half of his colonies, so are you still saying they have lost their skills?

brothermoo
13-03-2013, 11:44 AM
Or maybe these guys have been too busy lecturing up and down the country it has been to the detriment of their bees?

Not that I claim to know! Each case should be considered for all factors rather than just blaming one factor for everything that is wrong

I think losses are going to be high this winter. They were low last winter.
Look at Murray McGregor's results last winter, losses around 5% over 2000 colonies.
They used neonicotinoids on the same areas in 2011 and 2012 but the colony losses in the subsequent winters are likely to be very different.
Don't you think other factors may be in play?

I am very dubious about Murray McGregor's assessments. Whenever a colony perishes, he seems to call it a 'bog standard dead-out' without further discrimination.
He also imports a lot of bees, some of them will be to counter the 'bog standard deadouts'.


Anyway, I re-read chapter 9 'Pests and Diseases' of 'Guide to Bees and Honey' by Ted Hooper (1997) over night:

He gives very detailed accounts of all common and rare afflictions of bees in the UK, but 'sudden dwindling during winter leaving tiny clusters' is not mentioned at all!
If you claim that it has always been common then you'd better come up with a decent source for your statements.

I encourage all beekeepers to check their books that pre-date neonics for such references.

Colony Collapse Disorder has got a set of very distinctive characteristics.

Yes it has but not in the simple way you are claiming.
Here is info from MAAREC the main research group into CCD


The Mid-Atlantic Apiculture Research and Extension Consortium (MAAREC) is the current clearing house for CCD-based information produced by the CCD Working Group. Composed of scientists, beekeepers, industry, and government officials, the CCD Working Group has defined the symptoms of CCD colonies as follows:
Collapsing Colonies

An insufficient number of bees to maintain the amount of brood in the colony
A workforce composed largely of younger adult bees
The presence of a queen
The cluster's reluctance to consume food provided to them by the beekeeper

Collapsed Colonies

Complete absence of adult bees in colonies, with few or no dead bees in or around colonies
The presence of capped brood
The presence of food stores--both honey and bee bread--that are not robbed by other bees or typical colony pests, such as small hive beetles or wax moths. If robbed, the robbing is delayed by a number of days

What Causes CCD?

CCD may not be a new disorder. Over the past fifty to sixty years, many colonies have died in connection with symptoms similar to those of CCD. In older literature, the symptoms were blamed on disorders called spring dwindle disease, fall dwindle disease, autumn collapse, May disease, and disappearing disease. These historic occurrences may not share a common cause with modern-day CCD, but they do share its symptoms.



http://solutionsforyourlife.ufl.edu/hot_topics/agriculture/colony_collapse_disorder.html

The dwindle I see is with a rump of older bees which have a queen present. Often brood rearing has not even started up yet. Note the mention of 'over the past 50 or 60 years' and neonicotinoids have barely 20 in the marketplace.

The bees take feed as normal in the autumn.

Dead colonies get robbed out if they are not sealed up.

More from MARREC (http://edis.ifas.ufl.edu/in720)


The cause of CCD is currently under investigation. At this point, almost every possible and realistic cause remains a possibility. The following list of leading candidates--in no particular order--is not comprehensive and may change as new information becomes available. Such changes could result in the addition or exclusion of any of the following potential causes.

For more detailed information about each possible cause, see the original publication, Colony Collapse Disorder (CCD) in Honey Bees.

Traditional bee pests and diseases.
Most likely they are not responsible for CCD, as they do not have a history of producing those symptoms, but they may exacerbate the problem.
Bee management. Management style is a broad category, but it can include the type of income pursued with bees--honey production, pollination services--or the routine colony management that beekeepers perform--splitting hives, swarm control, chemical use.
Queen source. Lack of genetic diversity and lineage of bees--both related to queen quality--are being investigated as possible causes of CCD.
Chemical use in bee colonies. Chemicals used to control bee maladies have a variety of sub-lethal effects on all honey bees--workers, queens, and drones--even when the chemicals were used according to label and in accordance with best management practices suggested by specialists.
Chemical toxins in the environment. In addition to being exposed to toxins while foraging, honey bees may also encounter toxins by drinking water contaminated with chemical runoff, encountering various household or commercial chemicals outside of the hive, or via direct inhalation.
Genetically modified crops. Many seeds from which genetically modified crops are grown are dipped first in systemic insecticides that later may appear in the plants' nectar and pollen, making genetically modified plants suspect because of their chemical treatment history, not because of their modified genetics.
Varroa mites and associated pathogens. Varroa mites remain the world's most destructive honey bee killer, so they, the viruses they transmit, and the chemical response they elicit from beekeepers are considered possible causes of CCD.
Nutritional fitness. Malnutrition causes stress to bees, possibly weakening the bees' immune systems. Weak immune systems can affect bees' ability to fight pests and diseases.
Undiscovered or new pests and diseases. Undiscovered, unidentified, or recently-introduced pests and pathogens are considered possible causes of CCD.


Many scientists believe that CCD is caused by some combination of the factors above. For example, some dead bees showing CCD symptoms have had elevated levels of normally-benign pathogens in their bodies, possibly indicating a compromised immune system.

In theory, any stress or combination of stresses--such as chemicals, genetic bottlenecks, or varroa--can suppress a bee's immune system. Considering synergistic effects as a potential cause of CCD makes the disorder increasingly more difficult to study.

Jonathan, you can't come up with any evidence that CCD symptoms can be considered 'normal'.

We are losing millions of colonies to this problem every year since the widespread use of neonics has started.

As I said, I read all of Chapter 9.
There he says it's rare to lose a colony to nosema, as the bees get over it on their own.
He also says it's rare to lose a queen.

Ever since the widespread use of neonics started beekeeping has changed beyond recognition:

Areas that used to be bee heavens are losing their bee populations fast, queen problems are rampant, and sudden die-offs, especially during winter, have become the norm.

The more skilled members will do the denying, debunking, ridiculing, character assassinations etc.


On non beekeeping fora, Bayer&Co can just hire PR companies for these tasks, but as beekeeping fora require a certain amount of knowledge, the pool of mason beekeepers comes in handy for the job.




Perhaps at this point I should let folk know that Randy Oliver, bless him, advocates using Mason jars for Varroa monitoring. I guess he must be in the club (OK John, Craft ... see my inexperience in these matters!) too then.

All jar sample numbers in this article assume a 300-bee sample (exactly 3/4” of bees in a quart Mason jar—count ‘em once, and mark the jar).

Hey don't knock that masonic thread on biobees (http://www.biobees.com/forum/viewtopic.php?t=14291). I just found it the other day and saw I got a name check.
Comedy gold does not appear before us every day so give thanks when you find a thread like that.
To be honest I don't think the Masons would have me as I am a vegetarian and you have to do something with a goat. So they say anyway, obviously I have never been in a Masonic Lodge. Oops, nearly gave the game away. Mentioned it once.
I reckon I could manage either a secret handshake or a funny walk with a reasonable amount of applomb but not the goat.

You have to feel for the couple of sensible posters on the thread who got shot down in flames for not sipping from the font of conspiracy.

And what about this Lodge (http://www.otterlodge.co.uk/). The pieces are starting to fall into place.

LOL. Would never have thought to google that.

Someone somewhere likely has a restaurant named Pancreas Lodge. Good snappy name and would look good on a letterhead.

Wow, where's the popping eyeball smiley when you need it?

Can I suggest that my stack of supers was actually collapsed by the government rather than blown over by the wind?

A valid hypothesis and anyone who questions it is clearly guilty of lazy thinking.

What task were you given to prove you are worthy?
Have you mastered that ukelele yet?

Maybe the disappearing bees have ended up in the burgers along with Shergar and the rest of the horses.
If Bayer is smart enough to hire thousands of shills to post on the bee forums and Co-opt illuminati like the Curator of the Commonwealth Potato collection it should be but a simple task to bulk up those burgers with yet more extraneous DNA.

Building my burger business bee by bee.

See I can write snappy advertising which only goes to show I am likely but a pawn of the dark forces.

So Lodge-Master Neil, would you agree with Doris that some of my statements are 'very odd'
Make your mind up for yourself now.
Don't succumb to any undue influence from the Thetons in the room.
They are devious little critters and they know how to mess with your head.

I have always prided myself in the singular lack of oddness relating to each and every word I utter.

I've got my water spray which was given to me by the Grand Master of the Lodge.. oops .. Have I let the feline out of the bag? :eek:


I did not dare comment on the Masonic thread on Biobees for fear of spoiling the fun....

I won't be looking . I don't buy pigs in pokes:)
I do notice the site is not averse to accepting sponsors from all and sundry including mobile phone (harmful to bees?) companies and credit card pushers . "Pots and Pans" :D

There is nothing quite like a Jon in full flow, perhaps partially fuelled by a glass or two of wine.

Post of Year (for the day) unless Calum or someone can better it in the next four hours.

No wine involved for a change. Bushmills sponsored the UBKA event at the weekend and I got given a litre of some new honey whiskey product they are promoting, as a token of someones esteem.
No point in leaving something like that languishing at the back of the shelf when the masons are at large. Be careful out there!
