The Corn Rootworm Trap Network is 5 years old! We have learned a lot about corn rootworm populations here in Ontario and we value the efforts of all trap participants who have monitored sites each season. A special thanks goes to Dan Bihari, Senior GIS Specialist, OMAFA for maintaining the trap network platform and to our sponsors including Grain Farmers of Ontario (GFO), Agricultural Biotechnology Stewardship Technical Committee (ABSTC) and OMAFA for funding trap supplies.
