Mystery Ailment Strikes Honeybees — No honeybees and we don’t eat. The chain reaction goes right up and down the food chain. I’m guessing this has something to do with that mite which the big commercial beekeepers have been killing with bug poison not noticing that bees are bugs too!

A mysterious illness is killing tens of thousands of honeybee colonies across the country, threatening honey production, the livelihood of beekeepers and possibly crops that need bees for pollination.

Researchers are scrambling to find the cause of the ailment, called Colony Collapse Disorder.

Reports of unusual colony deaths have come from at least 22 states. Some affected commercial beekeepers — who often keep thousands of colonies — have reported losing more than 50 percent of their bees. A colony can have roughly 20,000 bees in the winter, and up to 60,000 in the summer.

“We have seen a lot of things happen in 40 years, but this is the epitome of it all,” Dave Hackenberg, of Lewisburg-based Hackenberg Apiaries, said by phone from Fort Meade, Fla., where he was working with his bees.

The country’s bee population had already been shocked in recent years by a tiny, parasitic bug called the varroa mite, which has destroyed more than half of some beekeepers’ hives and devastated most wild honeybee populations.
