Suddenly, the Bees are Simply Vanishing

Scientists are at a loss to pinpoint the cause.
The die-off in 35 states has crippled beekeepers and threatened many crops.

The dead bees under Dennis vanEngelsdorp's microscope were like none he had ever seen.

He had expected to see mites or amoebas, perennial pests of bees. Instead, he found internal organs swollen with debris and strangely blackened. The bees' intestinal tracts were scarred, and their rectums were abnormally full of what appeared to be partly digested pollen. Dark marks on the sting glands were telltale signs of infection.

"The more you looked, the more you found," said VanEngelsdorp, the acting apiarist for the state of Pennsylvania. "Each thing was a surprise."

VanEngelsdorp's examination of the bees in November was one of the first scientific glimpses of a mysterious honeybee die-off that has launched an intense search for a cure.

The puzzling phenomenon, known as Colony Collapse Disorder, or CCD, has been reported in 35 states, five Canadian provinces and several European countries. The die-off has cost U.S. beekeepers about $150 million in losses and an uncertain amount for farmers scrambling to find bees to pollinate their crops.

Scientists have scoured the country, finding eerily abandoned hives in which the bees seem to have simply left their honey and broods of baby bees.
