Controversial Pesticides Can Decimate Honey Bees, Large Study Finds

"Europe's largest field trial of controversial insecticides called neonicotinoids has delivered a split verdict on the danger they pose to bees. The £2.8 million, 2-year-long study of 33 sites in the United Kingdom, Hungary, and Germany, described this week in Science, provides the first real-world demonstration that agricultural use of these common pesticides can hurt both domesticated honey bees and wild bees. But on German farms, the honey bees did just fine, suggesting that in some situations colonies can weather the toxicity."
