Pea leaf weevil chows down on Western Manitoba

Farmers in Western Manitoba are now seeing heavy feeding damage from the crop-damaging insect pest, which was first found in the province in 2019

Pea leaf weevil has spread as far east as Manitoba's Ontario border, while the west has become a Prairie-wide hotspot for the pest insect.

If you’re a grower, you’ve likely got pest insects at some level and hopefully at a minimum. As John Gavloski, extension entomologist with Manitoba Agriculture, pointed out at the Crop Diagnostic School last month in Carman, there are particular crop pests to keep a close eye on this year. In this video, Gavloski shares which


Pterostichus melanarius ground beetles have garnered interest as possible predators for pea leaf weevil.

Management of pea leaf weevil is tricky, since by the time the farmer knows they have a problem, it’s often too late to spray

Pea leaf weevil is a nasty pest of peas and faba bean and its quirky behaviour makes it almost impossible to manage. The weevils are small and difficult to see. The farmer often doesn’t know they’re in the field until they find nicks in the leaves of their crop. By that time, it’s too late

Insects posing problems in Saskatchewan crops

Grasshopper, flea beetle damage already reported

MarketsFarm – Although it’s still early in the growing season, some insect pests have already posed a threat to crops in Saskatchewan or could do so in the near future, according to James Tansey, provincial specialist for insects/invertebrate pest management. Among the pests he cited were grasshoppers, flea beetles and pea leaf weevils.  Tansey said


A trap crop could lure the pests into a spot where they can be more readily managed.

Pea leaf weevil a tough pest to control

Uneven emergence and unpredictable life cycle make it a worthy opponent

The pea leaf weevil has a biology that’s a real pain in the anatomy when growing field peas or faba beans. Whatever the management strategy, the beetle shrugs and walks away pretty much unscathed. Agriculture Canada entomologist Meghan Vankosky in Saskatoon has spent the last few years looking at the weevil’s biology to find a

“Initially, it was in the Northwest where we were finding them and then, last year, we found them in the Southwest as far as Gladstone and into the Central region.” – Laura Schmidt.

Pea leaf weevil of growing concern

This newcomer is still a small problem here but it could thrive under Manitoba’s wetter conditions

Manitoba is now on the map — and this isn’t good news for farmers. It’s the risk map for the pea leaf weevil published by the Prairie Pest Monitoring Network, and this weevil, a pest that zeroes in on faba beans and field peas, now calls Manitoba home. “The first year we found it in


Field peas show signs of notching after being fed on by adult pea leaf weevils.

Time to tag pea leaf weevil

Agronomists hope a survey on pea leaf weevil will give a better sense of where the pest is and how many of them there are

It’s time to put Manitoba on the map — the risk map for pea leaf weevil, that is. Manitoba is the last Prairie province to get the pest, but the province’s bug experts and pulse specialists know it’s lurking. Not only that, according to Laura Schmidt, production specialist with the Manitoba Pulse and Soybean Growers

What’s bugging you?

These three beetles are the latest addition to the pest spectrum in Manitoba

Manitoba farmers have, in recent years, found themselves hosts to three new uninvited guests. That was the message from John Gavloski, Manitoba Agriculture and Resource Development entomologist, to the Ag in Motion Discovery Plus virtual farm show this summer. He said all three of these new pests are types of beetle, and all three first

If you’re an Alberta farmer and your crops have got cutworms, Alberta Agriculture and Rural Development wants to know. Scott Meers, an entomologist with Alberta Agriculture and Rural Development, is asking farmers to report cutworms online. The province uses those reports to create an interactive map displaying cutworm sightings. Meers and provincial insect research technologist
