Bees exposed to high levels of pesticides suspected in colony collapse

Pesticides sprayed on crops could be making honey bees susceptible to a fatal parasite and contributing to recent declines in bee populations, according to a study.

Researchers found 35 pesticides, some at lethal levels, in the pollen collected from bees servicing major food crops in five states, including California, according to the study published online Wednesday in the journal PLOS One.

Levels for two chemicals were above the dose that would kill half a population within two days, according to the report. Pesticide residue was found on all the pollen samples, including those that the bees apparently collected from nearby wildflowers, according to the report.
