Professor Emeritus, Galen Dively and his colleagues have a new paper out in the Journal of Economic Entomology titled, “Sweet Corn Sentinel Monitoring for Lepidopteran Field-Evolved Resistance to Bt Toxins” The study demonstrates that the sentinel plot approach as an in-field screen can effectively monitor phenotypic resistance and document field-evolved resistance in target pest populations, improving resistance monitoring for Bt crops. As a direct result of Galen’s research, the EPA has proposed a number of changes to the way the agency monitors genetically modified crop technologies. This fall Galen presented his research at the Fall Entomology Seminar Series. Check out PhD students Darsy Smith and Veronica Yurchak's Seminar Blog summarizing that talk.
On a related note, a recent Maryland Farm & Harvest episode covered several stories on corn production, including a segment at the Beltsville Agricultural Research Center featuring Galen’s research on genetically modified corn.
