This research is interesting:

" Walter Haefeker, the German beekeeping official, speculates that “besides a number of other factors,” the fact that genetically modified, insect-resistant plants are now used in 40 percent of cornfields in the United States could be playing a role. The figure is much lower in Germany — only 0.06 percent — and most of that occurs in the eastern states of Mecklenburg-Western Pomerania and Brandenburg. Haefeker recently sent a researcher at the CCD Working Group some data from a bee study that he has long felt shows a possible connection between genetic engineering and diseases in bees.

The study in question is a small research project conducted at the University of Jena from 2001 to 2004. The researchers examined the effects of pollen from a genetically modified maize variant called “Bt corn” on bees. A gene from a soil bacterium had been inserted into the corn that enabled the plant to produce an agent that is toxic to insect pests. The study concluded that there was no evidence of a “toxic effect of Bt corn on healthy honeybee populations.” But when, by sheer chance, the bees used in the experiments were infested with a parasite, something eerie happened. According to the Jena study, a “significantly stronger decline in the number of bees” occurred among the insects that had been fed a highly concentrated Bt poison feed.

According to Hans-Hinrich Kaatz, a professor at the University of Halle in eastern Germany and the director of the study, the bacterial toxin in the genetically modified corn may have “altered the surface of the bee’s intestines, sufficiently weakening the bees to allow the parasites to gain entry — or perhaps it was the other way around. We don’t know.”

Of course, the concentration of the toxin was ten times higher in the experiments than in normal Bt corn pollen. In addition, the bee feed was administered over a relatively lengthy six-week period.

Kaatz would have preferred to continue studying the phenomenon but lacked the necessary funding. “Those who have the money are not interested in this sort of research,” says the professor, “and those who are interested don’t have the money.”"
