A Purdue University study shows that honeybees collect the vast majority of their pollen from plants other than crops, even in areas dominated by corn and soybeans, and that pollen is consistently contaminated with a host of agricultural and urban pesticides throughout the growing season.

Christian Krupke, professor of entomology, and then-postdoctoral researcher Elizabeth Long collected pollen from Indiana honeybee hives at three sites over 16 weeks to learn which pollen sources honeybees use throughout the season and whether they are contaminated with pesticides.

The pollen samples represented up to 30 plant families and contained residues from pesticides spanning nine chemical classes, including neonicotinoids - common corn and soybean seed treatments that are toxic to bees. The highest concentrations of pesticides in bee pollen, however, were pyrethroids, which are typically used to control mosquitoes and other nuisance pests.

"Although crop pollen was only a minor part of what they collected, bees in our study were exposed to a far wider range of chemicals than we expected," said Krupke. "The sheer numbers of pesticides we found in pollen samples were astonishing. Agricultural chemicals are only part of the problem. Homeowners and urban landscapes are big contributors, even when hives are directly adjacent to crop fields."
"If you care about bees as a homeowner, only use insecticides when you really need to because bees will come into contact with them," she said.

Organic vegetables with a few insect-caused holes taste better than unblemished supermarket ones.

    I'm not a professional. I'm a random dude who gave of his time, freely, to submit an article to a community site for discussion. So if you're demanding "professional" something from a place you pay nothing for, and don't contribute anything to, not even the merest soupcon of identity or reputation, then you're behaving like a ninny.

    It's just cheesy flamebait that ends up dominating the conversation. Might as well just post a goatse.
