Biotech crops vs. pests: Successes and failures from the first billion acres

argylesock says… This is the kind of thing that makes me doubt the promises made for GM crops. Pests evolve. So there’s limited time to enjoy the benefits of Bt crops, and any future crop that makes its own supply of pesticide. Planting GM crops takes the farmer into an arms race. It’s a similar story to the way using antibiotics takes the doctor or vet into an arms race. Because of evolution, several countries now ban the routine inclusion of antibiotics in animal feed. I’ll say it again: pests evolve.
