For 27 years, farmers and entomologists have co-operated to record insect data for the Prairie Pest Monitoring Network (PPMN). This has produced a unique scientific resource not available in other parts of the world, said Meghan Vankosky, Agriculture and Agri-Food Canada entomology research scientist and PPMN co-chair. Her peers in countries such as Australia have not surveyed the ebbs and flows of insect populations as widely or for as long as the PPMN. “Having so much information from such a huge geographical area over such a long period of time is very unique from what I understand,” she said.

Those orange and red, blob-like areas on insect survey maps are a farmer’s cue to action. Fields seeded with certain crops and located in and around these hotspots may require individual assessment and population control. Among cereal farmers, the most anticipated of these maps are those for grasshoppers, wheat stem sawfly and wheat midge.
