Pesticides can impair the behaviour of bumble bees and affect their ability to eat and rear their young, a new study has shown.

The research, which allowed humans to take a closer look at the bee in its environment, revealed how the pesticide neonicotinoid can harm its behaviour.

Findings - List - Concerns - Pollinators - Crop

The findings add to a long-standing list of concerns about these critical pollinators for that pollinate 70 of the around 100 crop species that feed 90 per cent of the world.

The study was published in Science journal and compared the behaviour of bees exposed to pesticides and bees who weren't.

Researchers - Cameras - Boxes - Chamber - Nest

Researchers placed cameras inside 12 specially made boxes that contained one chamber for a nest and another chamber for foraging.

Some bees were exposed to concentrations of the neonicotinoid imidacloprid similar to that expected in the environment. Others were not.

Environmentalists - Years - Pesticides - Bees - Livelihoods

What they found confirmed what environmentalists had been warning for years; that pesticides are killing bees and threatening our livelihoods.

The pesticide-exposed bees were less social in a variety of ways than bees not fed nectar that contained neonicotinoids.

'Exposure - Pesticide - Changes - Worker - Bee

'Exposure to the neurotoxic pesticide resulted in measurable changes in worker bee behaviour within the nest,' said the report.

'The workers were less active, less likely to feed and care for larvae, and more likely...
