Predicted 2010 Corn Rootworm Hatch
There were several reports of lightning bugs (fireflies) throughout the state last week. Some people correlate fireflies with corn rootworm larval hatch in the Midwest. Based on conversations with Marlin Rice, former ISU entomologist, and Mike Gray, entomologist from University of Illinois, they believe these events are unrelated. Instead, corn rootworm hatch predictions are more accurately based on temperature accumulations.
