UMD researchers have pulled together forty years of data to quantify the effects of Bt field corn, a highly marketed and successful genetically engineered technology, in a novel and large-scale collaborative study. Other studies have demonstrated the benefits of Bt corn or cotton adoption on pest management for pests like the European corn borer or cotton bollworm in corn or cotton itself, but this is the first study to look at the effects on other offsite crops in North America. By tracking European corn borer populations, this study shows significant decreases in adult moth activity, recommended spraying regimens, and overall crop damage in vegetable crops such as sweet corn, peppers, and green beans. These benefits have never before been documented and showcase Bt crops as a powerful tool to reduce pest populations regionally thereby benefitting other crops in the agricultural landscape.
