Cry toxin uptake by pests and implications for insecticide resistance management
Original language description
Choice and no-choice experiments were performed using the generalist predator, Harmonia axyridis, feeding upon the fall armyworm, Spodoptera frugiperda, a major insect pest of maize. Harmonia axyridis larvae were fed with 1-5 day-old S. frugiperda larvaefed Bt or non-Bt maize expressing Cry1Ab. Spodoptera frugiperda larvae are sensitive to Cry1Ab; larvae feeding on Bt maize are smaller and development is delayed. In choice-experiments, H. axyridis ate more Bt-suppressed S. frugiperda larvae than larvaeof the same age that had fed on non-Bt maize. Harmonia axyridis was not likely choosing prey based on whether it had fed Bt or non-Bt maize, but rather on the size of the larvae. These results may have implications for insect resistance management (IRM)for Bt crops.
