Colony Collapse Disorder has become a global problem for beekeepers and for the crops which depend on bee polination. Multiple factors are known to increase the risk of colony colapse, and the ectoparasitic mite Varroa destructor that parasitizes honey bees is among the main threats to colony health. Although this mite is unlikely to, by itself, cause the collapse of hives, it plays an important role as it is a vector for many viral diseases. Such diseases are among the likely causes for Colony Collapse Disorder.

Editor’s Note: On February 19-20, USDA held their 91st annual Agricultural Outlook Forum. This year’s theme was Smart Agriculture in the 21st Century: A Discussion on Innovation, Biotechnology, and Big Data. The “Protecting Our Food Supply” breakout session featured a panel discussion, “What’s the Buzz About Bees?” The following is a dsecription of the panel discussion with links to all three presentations.

Concern about seed treatments like neonicotinoids and their possible damage to pollinators — especially bees — is a subject farmers should be aware of.
Tom Kroll, seed treatment product manager for Nufarm Americas, Inc., spoke to farmers at the recent Corn/Soy Expo in Wisconsin Dells and mentioned that the concern about seed treatments and their possible impact on bees was largely based on laboratory data.
Kroll said studies in the field in Europe have found that CCD “has nothing to do with the insecticide” and is more about the varroa mite, a parasite of honey bees.

Cotton growers are urging EPA not to limit pesticide use in states that are crafting plans to protect pollinators, raising concerns that a forthcoming federal strategy for implementing President Obama’s memo on pollinator protection could curb state efforts to protect bees through better communication between growers and beekeepers.
EPA and the U.S. Department of Agriculture (USDA) are leading a federal Pollinator Health Task Force that is expected to release in the coming weeks a strategy for implementing President Obama’s June 20 memo on stemming pollinator declines by improving their habitat; assessing how pesticides and other stressors contribute to their declines; and acting where appropriate.

Editor’s Note: In comments on EPA’s study of the benefits of neonicotinoid-treated soybean seeds, serious concerns were raised that the agency’s study failed to reflect a thorough, systematic review of the relevant literature. The attached External Scientific Report, commissioned by the European Food Safety Authority, contains a “Systematic literature review on the neonicotinoids (namely active substances clothianidin, thiamethoxam and imidacloprid) and the risks to bees.” Stakeholders now the have the opportunity to review EFSA literature data base. Below is a brief overview of the study.

The Environmental Protection Agency’s top pesticide regulators met privately last month with pesticide industry-funded researchers to hear them make the case for the value of neonicotinoid insecticides, according to documents made public Feb. 10.
The researchers, Paul Mitchell and Pete Nowak from the firm Ag Informatics, were responding to a recently issued EPA study that found treating soybean seeds with neonicotinoids provides farmers with no significant financial or agricultural benefits.

Paul Stamets has had a life-long love affair with mushrooms, one that goes well beyond their culinary and psychedelic qualities. Wearing his signature hat — made from mushrooms — a turtle pendant and, always, a blue scarf, the nearly 60 year-old mycologist runs Fungi Perfecti, a family-owned farm and business in Shelton, Washington.
Varroa mites spread viruses that can be deadly to bees. Sheppard explained that what keeps many commercial beekeepers up at night is the fact that the pesticides currently used to control mites are becoming ineffective. Mites have such a short life span that they quickly evolve and develop resistance to synthetic pesticides.

Honey bee populations worldwide, important for pollination of our food crops, are being challenged by a highly damaging mite: Varroa destructor. In an effort coordinated by the Arista Bee Research Foundation a group of European beekeepers has, during last spring and summer, bred a first generation of European honey bees that can detect the Varroa mite, clean out infested brood and by doing so are expected to keep the number of Varroa mites under control. This is an important step in breeding healthier, Varroa resistant honey bees that can much better survive in an already challenging environment.

Some state agriculture officials are opposing possible restrictions on pesticide use as part of a federal pollinator protection strategy that EPA and other agencies are expected to release soon, arguing agencies should instead focus on improving coordination between farmers and beekeepers, though advocates contend federal restrictions are necessary.

Bees having to forage younger because older workers have been killed off by disease could be key factor behind colony collapse disorder
Stressed young bees that are forced to grow up too fast could largely account for disastrous declines in populations of the insects around the world, research suggests.
Bees usually begin foraging at two to three weeks old but when older workers are killed off by disease, lack of food or other factors they have to start younger.
Scientists who attached radio tracking devices to thousands of bees found that early-starters completed fewer foraging flights and were more likely to die on their first sortie.
