Without a Trace

You've no doubt heard of the case of the disappearing honeybees. This editorial offers a nice summary of the problem along with what many entomologists think are potential causes. Here are the key graphs:

As many as a quarter of the nation's commercially kept bees went missing last year, presumed dead, in a phenomenon now called colony collapse disorder. Inspector Paul Jackson said it is as much a mystery in Texas as it is in 24 other states and half a dozen nations. He said it happens overnight without warning signs of distress and with no evidence left behind. The bees simply disappear.

Jackson has yet to find a pattern in this worrisome phenomenon. One beekeeper may lose 5,000 hives in a day's time while another down the road 10 miles loses none. In Texas, as elsewhere, it is the large commercial colonies that are most affected.

Pollination is the name of the game. Beekeepers in Texas and several other states send thousands of hives to pollinate crops around the country, moving them from state to state and crop to crop. Texas hives are deployed as many as four or five times a year, carried about the country on 18-wheeler trucks.

This constant mobility has been cited as a possible cause for the disappearing hives. The resulting stress depresses bees' immune systems, making bees vulnerable to a host of diseases and parasites. And their road food diet of high fructose corn syrup has been compared to a human diet restricted to soft drinks. Other possible causes include pesticides and other poisons and genetically modified crops that might introduce pesticide into the pollen.

The penultimate sentence about the bees' road food diet has me concerned that my daughter might be in danger of suddenly disappearing.
