scientists, soldiers, and bees....,

NYTimes | It has been one of the great murder mysteries of the garden: what is killing off the honeybees?

Since 2006, 20 to 40 percent of the bee colonies in the United States alone have suffered “colony collapse.” Suspected culprits ranged from pesticides to genetically modified food.

Now, a unique partnership — of military scientists and entomologists — appears to have achieved a major breakthrough: identifying a new suspect, or two.

A fungus tag-teaming with a virus have apparently interacted to cause the problem, according to a paper by Army scientists in Maryland and bee experts in Montana in the online science journal PLoS One.

Exactly how that combination kills bees remains uncertain, the scientists said — a subject for the next round of research. But there are solid clues: both the virus and the fungus proliferate in cool, damp weather, and both do their dirty work in the bee gut, suggesting that insect nutrition is somehow compromised.

Liaisons between the military and academia are nothing new, of course. World War II, perhaps the most profound example, ended in an atomic strike on Japan in 1945 largely on the shoulders of scientist-soldiers in the Manhattan Project. And a group of scientists led by Jerry Bromenshenk of the University of Montana in Missoula has researched bee-related applications for the military in the past — developing, for example, a way to use honeybees in detecting land mines.

But researchers on both sides say that colony collapse may be the first time that the defense machinery of the post-Sept. 11 Homeland Security Department and academia have teamed up to address a problem that both sides say they might never have solved on their own.

“Together we could look at things nobody else was looking at,” said Colin Henderson, an associate professor at the University of Montana’s College of Technology and a member of Dr. Bromenshenk’s “Bee Alert” team. Fist tap Big Don.
