European corn borer (ECB) is one of the pest included in the Great Lakes and Maritimes Pest Monitoring Network. Those interested in monitoring for ECB in field and sweet corn in the region are welcome to submit their trap data each week to the network to populate the real time interactive maps and see graphs summarizing their trap catches. Each trap week starts Monday to Sunday. We ask that trap counts are entered into the network by late Tuesday and are reporting counts from the previous week. Depending on the location, traps should be going up in the next two weeks at the latest. In Ontario, installing two traps per field; one for E strain and one for Z strain is recommended. For other states and provinces, contact your extension entomologist or agronomist to determine which strain is present at your location(s).
