A large-scale study published by researchers from Royal Holloway University of London has drawn together the findings of a decade of agrochemical research to confirm that pesticides used in crop protection have a significant negative impact on the learning and memory abilities of bees. Their findings are published on 11 July in the Journal of Applied Ecology.
Ph.D. student Harry Siviter, alongside Professor Julia Koricheva, Professor Mark Brown, and Dr. Elli Leadbeater (all from Royal Holloway) combined data from a large number of studies in which bees that had been exposed to pesticides had to learn about floral scents, a test that is commonly used to measure learning and memory in bees.

Their research reveals that even at very low field-realistic dosages, pesticides have significant negative effects on bee learning and memory, with worker bees exposed to pesticides less likely to learn and memorise a rewarding scent. Learning abilities are a vital component of the search for food in bees, because individuals must remember what type of flowers to visit, where to find them,...
