In the laboratory: The bees were not found to be affected when fed on a diet of pollen containing up to 100 times the concentration of toxin found in the Bt maize pollen. Feeding trials with larvae also showed no effects.
In the field: Bee colonies in flight tents were fed with Bt maize pollen to which a 10-fold concentration of Bt toxin had been added.No negative effects were observed. There were no differences in terms of the number of bees, the foraging and brood care activity or the hatching weight compared with the non-Bt-fed bee populations.

A chance infestation by parasites (microsporidia) resulted in more significant damage to the Bt-fed colonies. The underlying mechanism which causes this effect is unknown.
