How Science Wiped Out the Invasive Pink Bollworm in the U.S.
Collaboration and a combination of transgenic cotton and sterile insect releases helped to eradicate the invasive pink bollworm.

Pink Bollworm Versus Bt Cotton: Three Countries, Three Results
A new article in the Journal of Economic Entomology examines varying levels of resistance to Bt toxins developed by the pink bollworm in the United States, China, and India over the last 20 years, illustrating the importance of incorporating refuge crops in Bt systems.

The Problems Driving Resistance to Bt Crops—and Some Proposed Solutions
Cotton and corn are threatened by growing resistance in the pest Helicoverpa zea (a.k.a. bollworm or corn earworm) to the insecticidal properties of Bt crops. Two researchers identify contributing factors and identify insecticide resistance management practices that could help slow the problem.

Beneficial Insects and Nematodes are not Harmed by Genetically-modified, Insect-resistant Plants
A large body of literature has shown that genetically-modified plants that produce proteins from the bacterium Bacillus thuringiensis (Bt) to protect themselves from insect pests have little to no effect […]
