The 2021 Great Lakes and Maritimes Pest Monitoring Network (GLMPMN) is up and running for the 2021 season. We are monitoring for black cutworm (BCW), corn earworm (CEW), European corn borer (ECB), fall armyworm (FAW), true armyworm (TAW) and western bean cutworm (WBC) across the region and are providing an interactive real-time map and trap data dashboard that summarizes the trap results by pest. Anyone is welcome to set up a trap and enter the trap data into the network.  Any crops being monitored for the pests listed above can be included on the network.  If your crop is not listed in the Survey 123 form, click on “Other” when entering and fill in what crop you are monitoring.

Important Network Links: Trapping Instructions and Trap Supply Needs – for each pest on the GLMPMN 2021.

The Great Lakes and Maritimes Pest Monitoring Network is a collaboration of state and provincial reps from Michigan, Ohio, New York, Ontario, Quebec, New Brunswick, Prince Edward Island, Nova Scotia and Newfoundland and Labrador. We are grateful for all of the crop consultants, scouts, extension personnel, farmers and researchers across this region that monitor these traps and send in their weekly trap counts. A big thank you to Jennifer Birchmore, Senior Geographic Information Specialist at OMAFRA for developing and maintaining the GLMPMN.
