There are several pest species of aphids that attack crops in Canada. Some species are very host-specific, such as the soybean aphid, but others can be found on several plant hosts. Aphids are known to be able to build numbers incredibly rapidly and so require careful scouting during the growing season. To unpack what we… Read More
There are two main insect pests of wheat that keep breeders busy: the wheat stem sawfly and the wheat midge. There is resistance to each and effective predators of each, but the insects still manage to eat a significant amount of wheat yield each year. To unpack how these two pests cut yield, quality, or… Read More
If your idea of a beneficial insect is one that sits back and waits for dinner to crawl on by, you’ve likely never heard about the secret lives of lacewings. Green lacewings are nothing short of ferocious, and, as Dr. Tyler Wist of Agriculture and Agri-Food Canada explains, they’re more like aphid-hunting lions than laid-back… Read More

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
Wheat head armyworm doesn’t only affect wheat; it can also affect barley, rye, oats, native and forage grasses like timothy, and even gets into wild oats — it’s got a wide host range to say the least. The impact of wheat head armyworm isn’t well documented, and part of the problem with researching them is… Read More

A good parasite doesn’t kill its host, but a good parasitoid does. What’s the difference and why? 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. A species of dirt-coloured seed bug in the family Rhyparochromidae, P convivus is often spotted in its nymph form, which is far from the colour of the soil in the prairies, with… Read More
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. While the threat has subsided a bit because of the discovery and use of the SM1 resistance gene, it’s important to remember that there is only one bullet in the chamber, and if it gets spent wheat crops will be, once again, at… Read More
