Pests could overcome Bt toxin mix in stacked GE cotton events
Laboratory studies suggest that it may be possible for insects to overcome two disparate toxins produced by genetically modified cotton. The results strike a cautionary note at a time when developers are racing to create crops that produce many different pesticides. Insects can become resistant to individual insecticides in much the same way as bacteria develop resistance to antibiotics. One way to reduce this threat is to adopt a ’pyramid’ approach and create crops that produce multiple toxins that target the same pest.
