Colony Collapse Disorder

Excerpts of a post by Peter Dearman @ GNN

...Sharon Labchuk is a longtime environmental activist and part-time organic beekeeper from Prince Edward Island. She has twice run for a seat in Ottawa’s House of Commons, making strong showings around 5% for Canada’s fledgling Green Party. She is also leader of the provincial wing of her party.

In a widely circulated email, she wrote:
"I’m on an organic beekeeping list of about 1,000 people, mostly Americans, and no one in the organic beekeeping world, including commercial beekeepers, is reporting colony collapse on this list. The problem with the big commercial guys is that they put pesticides in their hives to fumigate for varroa mites, and they feed antibiotics to the bees. They also haul the hives by truck all over the place to make more money with pollination services, which stresses the colonies."

Her email recommends a visit to the Bush Bees Web site at bushfarms.com.

Here, Michael Bush felt compelled to put a message to the beekeeping world right on the top page:
"Most of us beekeepers are fighting with the Varroa mites. I’m happy to say my biggest problems are things like trying to get nucs through the winter and coming up with hives that won’t hurt my back from lifting or better ways to feed the bees.

This change from fighting the mites is mostly because I’ve gone to natural sized cells. In case you weren’t aware, and I wasn’t for a long time, the foundation in common usage results in much larger bees than what you would find in a natural hive. I’ve measured sections of natural worker brood comb that are 4.6mm in diameter. …What most people use for worker brood is foundation that is 5.4mm in diameter. If you translate that into three dimensions instead of one, it produces a bee that is about half as large again as is natural. By letting the bees build natural sized cells, I have virtually eliminated my Varroa and Tracheal mite problems. One cause of this is shorter capping times by one day, and shorter post-capping times by one day. This means less Varroa get into the cells, and less Varroa reproduce in the cells."

Who should be surprised that the major media reports forget to tell us that the dying bees are actually hyper-bred varieties that we coax into a larger than normal body size? It sounds just like the beef industry. And, have we here a solution to the vanishing bee problem? Is it one that the CCD Working Group, or indeed, the scientific world at large, will support? Will media coverage affect government action in dealing with this issue?

These are important questions to ask. It is not an uncommonly held opinion that, although this new pattern of bee colony collapse seems to have struck from out of the blue (which suggests a triggering agent), it is likely that some biological limit in the bees has been crossed. There is no shortage of evidence that we have been fast approaching this limit for some time.

“We’ve been pushing them too hard,” Dr. Peter Kevan, an associate professor of environmental biology at the University of Guelph in Ontario, told the CBC. “And we’re starving them out by feeding them artificially and moving them great distances.” Given the stress commercial bees are under, Kevan suggests CCD might be caused by parasitic mites, or long cold winters, or long wet springs, or pesticides, or genetically modified crops. Maybe it’s all of the above.

This conclusion is not surprising, considering how the practice of beekeeping has been made ultra-efficient in a competitive world run by free market forces. Unlike many crops, honey is not given subsidy protection in the United States despite the huge importance of the bee industry to food production. The FDA has hardly moved at all to protect American producers from “honey pretenders” – products containing little or no honey that are imported and sold with misleading packaging. Rare is the beekeeper that does not need pesticide treatments and other techniques falling under the rubric of ‘factory farming.’

You might be justifiably stunned to know how little money is being thrown at this problem. A January 29, 2007 Penn State press release (just before CCD hit the big networks) stated: “The beekeeping industry has been quick to respond to the crisis. The National Honey Board has pledged $13,000 of emergency funding to the CCD working group. Other organizations, such as the Florida State Beekeepers Association, are working with their membership to commit additional funds.” A quick look at CostofWar.com will tell you that that $13,000 buys about 4 seconds of war at the going rate. Remember, these same scientists had presented the world with a similar threat level two years ago. Apparently they were ignored.

...Not surprisingly, the use of one or more new pesticides was, and likely remains, on the short list of likely causes of CCD. But more than pesticides could potentially be harming bees. Some scientists suspect global warming. Temperature plays an integral part in determining mass behavior of bees. To mention just one temperature response, each bee acts as a drone thermostat, helping cool or warm the hive whenever it isn’t engaged in some other routine.

...Surprise — it’s an ecosystem thing. As with honeybees and CCD, the root of the bumblebee problem lies in our modern rationalist drive toward endlessly ordering the world around us. The long-term solution is a return to a more natural ecological order. This interpretation needs to be conveyed when mainstream media tell the CCD story.

Of course, with all the parasites, pathogens, pesticides and transit to stress out our hardworking honey bees, they are in peril. Even if some silver bullet saves us from CCD, it is more than obvious that we need to pay more respect to bees, and to nature.

Collapsing Colony Disorder Impacts N.D.

BISMARCK, N.D. — North Dakota now is among about a dozen states where beekeepers report some of their bees are buzzing away from hives for good.

Judy Carlson, the apiary inspector for the state Agriculture Department, said North Dakota beekeepers are returning to the state after using their bees elsewhere to pollinate cucumbers and almond and orange trees.

The phenomenon, known as collapsing colony disorder, affects crops that depend on bees for pollination.

A survey of 15 out of the 179 beekeepers in the state found about half had poor or disappearing hives, she said.

"Some are reporting that they are losing 50 to 80 percent of their hives," Carlson said.

North Dakota, with an estimated 382,500 hives, led the country in honey production last year.

"This is a really big deal for the honey industry here," state Agriculture Commissioner Roger Johnson said. "It's a real mystery because bees have an enormously strong homing instinct, but in this case, they are flying away and never coming back and nobody knows where they went."

Randy Verhoek of Bismarck said he lost half his 13,000 hives this year, costing him about $400,000.

"We'd go out one day and find full boxes, and a week later they would just be gone," he said.

Verhoek said he lost money because he did not have his normal hive count for pollination in California almond orchards. He said he had to send weakened hives to Texas for rebuilding.

Verhoek and Gackle beekeeper John Miller, with 10,000 hives, say the phenomenon of collapsing colonies may have many causes, including drought, disease and insecticides...

Another POV: Requiem for the Honeybee

Neonicotinoid insecticides are harmful to the honeybee

There has been a great deal of concern over the decline of the honeybee across the US, Europe and Australia [1] (The Mystery of Disappearing Honeybees, this series). The United States National Research Council (USNRC) Committee of the Status of Pollinators in North America report [2] focused on the impact of parasites, fungi, bacteria and viruses, but did not pay much attention on the impact of pesticides and genetically modified (GM) crops, which may have lethal or sub-lethal effects on the bee’s behaviour or resistance to infection. There have been strong responses to the report on that account. On the other hand, any suggestion that GM crops and pesticides may be causing the decline of honeybees is met with heated denial from the proponents.

Certainly, honeybees are declining both in areas where GM crops are widely grown, and in other areas where GM crops are released in small test plots. Is there a common thread that links both areas? Yes there is, the universal use of systemic pesticide seed dressing in GM crops and conventional crops; in particular, the widespread application of a relatively new class of systemic insecticides - the neonicotinoids - that are highly toxic to insects including bees at very low concentrations. Systemic pesticide seed dressings protect the newly sprouted seed at a vulnerable time in the plant’s development. Seed dressings include systemic insecticides and fungicides, which often act synergistically in controlling early seedling pests.

The neonicotinoid insecticides include imidacloprid, thiamethoxam, clothianidin, and several others. Imidacloprid is used extensively in seed dressing for field and horticultural crops, and particularly for maize, sunflower and rapeseed (canola). Imidacloprid was detected in soils, plant tissues and pollen using HPLC coupled to a mass spectrometer. The levels of the insecticide found in pollen suggested probable delirious effects on honeybees [3]. For several years since 2000, French and Italian beekeepers have been noticing that imidacloprid is lethal to bees, and the insecticide is suspected to be causing the decline of hive populations by affecting the bee’s orientation and ability to return to the hive....
