Neonicotinoid study concludes bees harmed
The most extensive study to date on neonicotinoid pesticides concludes that they harm both honeybees and wild bees.
Researchers said that exposure to the chemicals left honeybee hives less likely to survive over winter, while bumblebees and solitary bees produced fewer queens.
The study spanned 2,000 hectares across the UK, Germany and Hungary and was set up to establish the "real-world" impacts of the pesticides.
The results are published in Science.
