Article Synopsis

Genetically engineered Bt crops like maize and cotton have significantly reduced insecticide usage and targeted pest control, but there are concerns about pests evolving resistance.
To counter resistance, the EPA mandates strategies such as planting a 20% refuge of non-Bt maize alongside Bt maize, while Bt cotton relies on diverse natural refuges.
The study highlights that the effectiveness of these refuges in managing Helicoverpa zea pests is influenced by the local presence of Bt and non-Bt crops, stressing the need for careful consideration in pest management strategies.
