Western corn rootworm (WCR) and northern corn rootworm (NCR) continue to dominate as economic pests throughout the U.S. and Canada. In response, the Corn Rootworm IPM Regional Working Group was formed during the spring of 2021 and continues to grow. Currently, we are made up of university, industry, and government personnel from at least 12 U.S. states and 5 Canadian provinces. Recently, high corn rootworm populations and the development of resistance to Bt corn hybrids in some areas has sparked greater interest in scouting and alternative management of corn rootworms.
