Predators delay pest resistance to Bt crops, says Cornell

Cornell University has recently released research regarding Bt crops and how it could potentially affect plants in the future. Genetically modified plants produce proteins that kill pests, also known as Bt (Bacillus thuringiensis). “To delay or prevent insect pests from evolving resistance to Bt crops, the U.S. Environmental Protection Agency promotes the use of multiple Bt genes in plants and the practice of growing refuges of non-Bt plants that serve as a reservoir for insects with Bt susceptible genes,” said Krishna Ramanujan, free lance writer at Cornell University.
