A new way to combat resistant pests stems from discovering how the widely-used natural insecticide Bt kills insects. Figuring out how Bt toxins punch holes in the cells of an insect's gut was the key ...

Cornell University entomologist Anthony Shelton finds when engineered crops containing just one Bt toxin grow near modified plants with two toxins, insects may more rapidly develop resistance to all ...

If you garden, you probably know that insects like to eat your fruits and vegetables before you do. Farmers know that too, and one way they address the wily insect pests is by engineering plants to ...

Genetically engineered (or GMO) corn that was developed to kill insect pests has been causing resistance in some of those very insects for several years. But the issue has not received as much ...
