Every year, Sask Wheat and other Prairie wheat groups go out and sample soil to look for wheat midge cocoons that have overwintered, and then create a forecast map from that information. The wheat midge forecast map is showing a lot of red, which is a bit alarming. Wheat midge is definitely on Tyler Wist’s… Read More

In this episode of the Pests & Predators podcast, host Shaun Haney is joined by Tyler Wist, research scientist and field crop entomologist with Agriculture Agri-food Canada at Saskatoon, Sask., to explore the role of parasitoids in field… Read More
In the last couple of years, aster leafhoppers have arrived around the third week of May, perhaps on the same wind that diamondback moths fly in on from the U.S. The aster leafhopper is a small, bullet-shaped insect that doesn’t directly damage the plant; instead it is a vector for the disease aster yellows. In… Read More
Agriculture and Agri-Food Canada (AAFC) is working to learn more about Peritrechus convivus, the little red bugs farmers have been finding in their fields.

What’s good for wheat growth is good for wheat midge, says research scientist Tyler Wist, of Agriculture and Agri-Food Canada, based at Saskatoon, Sask. What’s more, these tiny pests can cause big issues, even in very low numbers, so scouting is one key aspect of management. In this edition of RealAgriculture’s Wheat School, Wist also… Read More
Wheat midge is still a significant threat to wheat in Western Canada.
