For years scientists have been mystified and agriculturalists have been alarmed by honeybee die-offs. The collapse of the population of these essential crop pollinators in North America, estimated at about 20% of the bees, has variously been blamed on a mite, on pesticides, and on cell-phone radiation.
Now, it seems, scientists have finally discovered the real cause - a virus working synergistically with a fungus in the gut of the bees. Neither the virus nor the fungus are harmful by themselves but together they're apparently lethal.
