Studies claim bee brain damage by insecticides
Results from two new studies indicate that bee health can be damaged by combinations of neonicotinoid and organophosphate insecticides. Both consider the effects of a combination of the neonicotinoid insecticides, clothianidin and imidacloprid, and the organophosphate insecticide/acaricide, coumaphos, on bee brains and learning behaviour. Imidacloprid is widely used in the EU, but less so in North America. Coumaphos is not registered for use in the EU, and its use in the US is declining due to the development of resistance in its primary target, varroa mites.
