Many factors found in American bee deaths

WASHINGTON — The devastation of American honeybee colonies is the result of a complex stew of factors, including pesticides, parasites, poor nutrition, and a lack of genetic diversity, according to a comprehensive federal study published Thursday.

The problems affect pollination of US agricultural products worth tens of billions of dollars a year. The report does not place more weight on one factor over another, and it recommends a range of actions and further research.

Honeybees are used to pollinate many crops. Since 2006, millions of bees have been dying in a phenomenon known as colony collapse disorder.

Officials in the Department of Agriculture, the Environmental Protection Agency, and others involved in the study said there was not enough evidence to support a ban on one group of pesticides.
