"Pesticides Put Bumblebee Colonies at Risk of Failure"

"Pesticides used in farming are also killing worker bumblebees and damaging their ability to gather food, meaning colonies that are vital for plant pollination are more likely to fail when they are used, a study showed on Sunday."

"The United Nations has estimated that a third of all plant-based foods eaten by people depend on bee pollination and scientists have been baffled by plummeting numbers of bees, mainly in North America and Europe, in recent years.

British scientists said they exposed colonies of 40 bumblebees, which are bigger than the more common honeybee, to the pesticides neonicotinoid and pyrethroid over four weeks at levels similar to those in fields.

Neonicotinoids are nicotine-like chemicals used to protect various crops from locusts, aphids and other pests."
