A world without bees?

This really is becoming a problem. Bee colonies have been on a decline for several years now and, so far, no rebound is in sight. This worrisome trend goes, sorry to say Pooh Bear, well beyond just honey. Bees are the primary carriers of pollen. Pollen, as we all know, is used to spread genetic material amongst plants to aid in propagation. In other words, they spread pollen to make seeds. Yes, other insects, even birds, do this, but bees are by far the largest contributor of pollen distribution.

A survey of bee health released Tuesday revealed a grim picture, with 36.1 percent of the nation's commercially managed hives lost since last year.

As beekeepers travel with their hives this spring to pollinate crops around the country, it's clear the insects are buckling under the weight of new diseases, pesticide drift and old enemies like the parasitic varroa mite, said Dennis vanEngelsdorp, president of the group.

This is the second year the association has measured colony deaths across the country. This means there aren't enough numbers to show a trend, but clearly bees are dying at unsustainable levels and the situation is not improving, said vanEngelsdorp, also a bee expert with the Pennsylvania Department of Agriculture.

"For two years in a row, we've sustained a substantial loss," he said. "That's an astonishing number. Imagine if one out of every three cows, or one out of every three chickens, were dying. That would raise a lot of alarm."

About 29 percent of the deaths were due to colony collapse disorder, a mysterious disease that causes adult bees to abandon their hives. Beekeepers who saw CCD in their hives were much more likely to have major losses than those who didn't.

"What's frightening about CCD is that it's not predictable or understood," vanEngelsdorp said.

On Tuesday, Pennsylvania Agriculture Secretary Dennis Wolff announced that the state would pour an additional $20,400 into research at Pennsylvania State University looking for the causes of CCD. This raises emergency funds dedicated to investigating the disease to $86,000.

The issue also has attracted federal grants and funding from companies that depend on honeybees, including ice-cream maker Haagen-Dazs.

Because the berries, fruits and nuts that give about 28 of Haagen-Dazs' varieties flavor depend on honeybees for pollination, the company is donating up to $250,000 to CCD and sustainable pollination research at Penn State and the University of California, Davis.
