Genetic study confirms insects are still not resistant to Bt toxin.
Cotton that has been genetically engineered to be toxic to pests remains effective after nearly a decade in the field, scientists have announced, defying predictions that insects would evolve to tolerate them. Widespread planting of genetically modified (GM) cotton across the southern United States has not increased the incidence of resistance in the major insect pest, pink bollworm.
