Shan Bilimoria, a professor and molecular virologist, said the bees may be taking a one-two punch from both an insect virus and a fungus, which may be causing bees to die off by the billions.
Bilimoria is part of a team of researchers searching for the cause of the collapse. Led by research professor Jerry Bromenshenk from the University of Montana in Missoula, the group also includes virologists and chemists from the U.S. Army Edgewood Chemical Biological Center and the Instituto de Ecologica AC in Mexico.
Their study was published this week in the peer-reviewed journal PLoS ONE.
“At this stage, the study is showing an association of death rates of the bees with the virus and fungus present,” Bilimoria said. “Our contribution to this study confirms association. But even that doesn’t prove cause and effect. Not just yet.”
The mysterious colony deaths have caused major concern with scientists since much of agriculture depends on bees to pollinate crops.
To discover what might be attacking bee colonies, the team ground up dead bees that had succumbed to colony collapse disorder. Using analytical equipment, researchers discovered through spectroscopic analysis evidence of a moth virus called insect iridescent virus (IIV) 6 and a fungal parasite called Nosema.
The insect virus is closely related to another virus that wiped out bee populations 20 years ago in India, he said. Also, unlike previous research that found the deaths may be caused by a virus with RNA, the IIV 6 contains DNA.
“Our DNA discovery puts this field in a whole new direction,” he said.
Bilimoria said Texas Tech supplied the virus material for the experiments and were tested on bees with the fungus. Though an association between exposure and death was found, scientists don’t yet know if the two pathogens cause CCD or whether CCD colonies are more likely to succumb to the two pathogens.
“To prove cause and effect, we will have to isolate the virus and fungus from bee colony, and then reinfect with same virus and fungus,” Bilimoria said.
In the next part of the research project, Bilimoria will work to isolate the virus from infected bees.
“Once we isolate and identify the virus, we will have a way of monitoring it,” he said. “It is easier to fight the problem if we know what the culprit is.”

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
