Beijing, 23/04/2015 (The People’s Daily Online) – The number of bees is declining alarmingly. The colony collapse worries scientists trying to find an explanation. Many point to neonicotinoid insecticides, which at this time are subject to a moratorium in the EU for use in seed treatment.
The first of these works shows that neither the bees and bumblebees are able to distinguish by taste the three neonicotinoid insecticides commonly used, so they have no way to avoid them. This risk of poisoning when contaminated collect nectar.
Moreover, the study shows that prefer a sugar solution containing these pesticides, which act on the central nervous system, compared to other “clean” containing only sugar water.
According to the study authors, the reason for the preference of insects by these harmful substances is the same reason that some people are hooked to snuff. Neonicotinoids receptors act in the brain of bees similar to nicotine in the human brain, said.
