“A study at the University of Jena from 2001 to 2004 showed that toxins from a genetically modified maize variant designed to repel insects, when combined with a parasite, resulted in a “significantly stronger decline in the number of bees” than normal.
“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.”
Kaatz was desperate to continue his studies but funding was cut off.”
