Study Shows Virus-Fungus Culprit for Bee Colony Collapse

A fungus and virus working together could be the cause of a collapse in bee colonies over the past several years. Since 2006, about 20 to 40 percent of bee colonies in the U.S. have been dying off. Several causes of colony collapse have been investigated, but collaboration between Army scientists and researchers at the University of Montana revealed that a virus-fungus, which was present in each of the killed colony groups studied, is the possible culprit. Separately, the virus and fungus can do no harm, but together, they are lethal. (New York Times) Read more.
