Field study shows how a GM crop can have diminishing success at fighting off insect pest

Typical human reaction, esp. when profits are concerned, to ignore warning signs of future problems.

A new study from North Carolina State University and Clemson University finds the toxin in a widely used genetically modified (GM) crop is having little impact on the crop pest corn earworm (Helicoverpa zea) - which is consistent with predictions made almost 20 years ago that were largely ignored. The study may be a signal to pay closer attention to warning signs about the development of resistance in agricultural pests to GM crops.

"These findings are a reminder that we need to pay attention to potential clues about developing resistance," Reisig says. "We can't expect there to always be a new GM toxin available to replace the old one."
