The first comprehensive survey of CCD-affected bee populations
that suggests CCD involves an interaction between pathogens and other stress factors. We present evidence that this condition is contagious or the result of exposure to a common risk factor. Potentially important areas for future hypothesis-driven research, including the possible legacy effect of mite parasitism and the role of honey bee resistance to pesticides, are highlighted.
The European Commission has adopted a proposal to restrict the use of three pesticides belonging to the neonicotinoid family (clothianidin, imidacloprid and thiametoxam) for a period of two years.
The Commission's action was in response to the European Food Safety Authority's (EFSA) scientific report,
which identified "high acute risks" for bees as regards exposure to dust in several crops such as corn, cereals and sunflowers, to residues in pollen and nectar in crops like oilseed rape and sunflower and to guttation in corn.
In the US, the EPA is not currently banning or severely restricting the use of the neonicotinoid pesticides. The neonicotinoid pesticides are currently being re-evaluated through registration review.
Four major environmental groups are demanding that Ottawa force pesticide makers to provide scientific studies looking at whether their products are killing off bees.
Health Canada's Pest Management Regulatory Agency has been asking registered pesticide manufacturers for the studies since 2004.
But despite several notices, the studies haven't been produced, while the pesticides in question continue to be manufactured and sold.Read More
An excellent presentation by Graham White, which covers the effect of neonicotinoids on bees. http://www.youtube.com/watch?v=rb_0xFwCYx4&feature=youtu.be
