Climate change, transgenic corn adoption and field-evolved resistance in corn earworm. Pests aggravate the agricultural costs of climate change. Understanding climate change interaction with transgenic crops, a key insect pest management strategy, helps minimize agricultural losses. We found that increasing temperature anomaly and its interaction with high Bt acreage probably accelerated Bt resistance development in a major crop pest, corn earworm. Bt resistant corn earworms may spread further given extensive Bt adoption, and their range expansion due to climate change. We highlight the need to incorporate evolutionary processes affected by climate change into Bt resistance management programs, and the challenges posed by climate change for Bt biotechnology based insect pest management. Check out the full article here. Dilip Venugopal completed his Ph.D. in the Entomology Department in 2014, co-advised by Drs. William Lamp and Galen Dively. He is now a AAAS Science & Technology Fellow at the Environmental Protection Agency in Washington, D.C.
