Bees may become addicted to nicotine-like pesticides in the same way humans get hooked on cigarettes, according to a new study, which was released as a landmark field trial provided further evidence that such neonicotinoids harm bee populations.
In a study published in the journal Nature, scientists from Newcastle Univeristy showed that bees have a preference for sugar solutions that are laced with the pesticides imidacloprid and thiamethoxam, possibly indicating they can become hooked on the chemicals.
Also published in Nature on Wednesday was a study that has been endorsed as the most conclusive evidence yet that the group of pesticides, neonicotinoids, harm wild bee populations, which include bumblebees and solitary bees.
Scientists from Lund University in Sweden carried out the first successful ‘real world’ experiment on the effect of neonicotinoids on bees and found that wild bee populations halved around fields treated with them. Bumblebee hives stopped growing and produced less queens where the chemical was present. However the study did not find evidence that more robust honeybees, which are used to pollinate many crops, were affected.
Dr Maj Rundlöf, the lead author of the study, said the impacts on wild bees were “dramatic”. “I think it’s really important evidence when discussing how neonicotinoids used in real agricultural landscapes influence bees,” she said.
