Buzz Over Bee Health: New Pesticide Studies Rev Up Controversy
"Researchers in the United Kingdom conducted a lab experiment to see which kind of food sources bees are drawn to. They offered bees a choice between a plain, sugary solution and one laced with neonics. They found the bees preferred the pesticide solution."
"I think it's a surprising result," Raine says, "because the data suggest that they can't taste the [pesticides], but they are still preferring them."
It's possible that they're getting a little buzz from the neonics, similar to the way a human may get a buzz from nicotine.
