Western corn rootworm (WCR) and northern corn rootworm (NCR) continue to dominate as
economic pests throughout the U.S. and Canada. 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. 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 11 U.S. states and 5 Canadian provinces.
