New York Times: The mystery of what is killing off the honeybees may have been solved by a unique partnership of military scientists and entomologists. Since 2006, 20–40% of US bee colonies have disappeared. The probable reason: A fungus tag-teaming with a virus have apparently interacted to cause the problem, according to a paper by US Army scientists in Maryland and bee experts in Montana in the online science journal PLoS One. The scientists say that more research is needed to determine, for example, how further outbreaks might be prevented, and how much environmental factors such as heat, cold or drought might play a role.
