argylesock says… Some of the most popular GM (genetically modified, also called genetically engineered, GE) crops are Bt crops. That means that they make an insecticide called Bt toxin in the crop plant’s own tissues. The Bt toxin kills insect pests that eat the crop. After a while – sometimes a short while – the insects evolve to resist that Bt toxin. Here’s some science about how well Bt crops are succeeding, and about how soon they fail, and about how farmers can manage the pests’ evolution.
