Corn earworm (Helicoverpa zea) is a major pest of corn and other crops. In the past 20 years, as usage of Bt corn has risen, H. zea has steadily developed greater resistance to the insecticidal properties of the genetically modified corn, and a new study points to climate change as a factor accelerating the pest’s development of resistance.
