"Are Agriculture's Most Popular Insecticides Killing Our Bees?"

"Environmentalists and beekeepers are calling on the government to ban some of the country's most widely used insect-killing chemicals."

"The pesticides, called neonicotinoids, became popular among farmers during the 1990s. They're used to coat the seeds of many agricultural crops, including the biggest crop of all: corn. Neonics, as they're called, protect those crops from insect pests.

But they may also be killing bees.

Christian Krupke, a professor of entomology at Purdue University in Indiana, is among the scientists whose research has alarmed beekeepers. Last month, I caught up with Krupke at a DoubleTree Hotel in Bloomington, Ill., where he was giving a talk to several hundred farmers and the agricultural consultants who advise them about seeds, fertilizer and pesticides. The meeting was organized by GrowMark, a farm supply company."
