Cereal leaf beetle larvae may leave long, white streaks on cereals, forage grasses and some grassy weeds.

AAFC wants your cereal leaf beetles

Agriculture and Agri-Food Canada has put out a call for samples to monitor biocontrol on the insect

Agriculture and Agri-Food Canada (AAFC) is asking farmers to keep an eye out for feeding damage and “shiny, slug-like creatures” on cereals, potential markers of cereal leaf beetle larvae.  “We need samples to monitor the biocontrol insect that kills this pest,” said Dr. Haley Catton. If found, AAFC is asking farmers to send them samples

Flea beetles.

The four horsemen of the crop-pocalypse

Three of the big four crop pests could be poised for a comeback in the coming season

Four pests caused the most problems last season, and given the right spring conditions, three are poised to return. That’s according to John Gavoloski, provincial entomologist, who says farmers should head into spring watching the weather and with their eyes open. “If I had to predict which three pests farmers could be at a higher


Flea beetle is one of the pests a Manitoba researcher is targeting with biotechnology.

Targeting your crop enemies

Is the future of crop protection environmentally friendly biotechnology?

So far biotechnology in agriculture has driven the use of crop protection products through genetically engineered herbicide resistance. But the next wave could displace at least some of those applications by opening up another front in the war on two familiar canola concerns — sclerotinia and flea beetle. Mark Belmonte, a professor of biological science

Cabbage seedpod weevil.

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

Cabbage seed pod weevil.

Keep an eye out for these three ‘new’ insect pests

Entomologists are tracking the progress of cereal leaf beetles,cabbage seedpod weevils and pea leaf weevils across Manitoba

A provincial entomologist is asking farmers and agronomists to keep their eye out for three pests making inroads in Manitoba. Why it matters: Provincial entomologist John Gavloski has a watch list of pests starting to creep their way into Manitoba. The cereal leaf beetle was first spotted in Manitoba in 2009 and has spread from


It might look bad, but there’s a pretty good chance those canola 
volunteers aren’t actually doing that much harm.

What to do with those yellow soybean fields?

Now is also the time to scout for Bertha armyworms and diamondback moth

That bright yellow volunteer canola in your soybeans might look worse than it really is — so before trying to control it, consider whether it makes economic sense. That’s the advice Tammy Jones, Manitoba Agriculture and Resource Development’s (MARD) weed specialist gave in an interview following a Crop Talk webinar July 15. (Jones’ last day

The province has urged canola growers in parts of the province to be on watch for diamondback moth larvae and pupae.

Heads-up on diamondback moth

Eastern Manitoba and the southern Interlake have been hot spots for the province’s diamondback moth trapping program this year

Canola growers in eastern Manitoba and the southern Interlake should be keeping an extra eye out for diamondback moth this year, experts have warned. Manitoba Agriculture and Resource Development has noted exponentially higher counts of diamondback moth in those areas, something provincial entomologist John Gavloski has linked to windy weather in June blowing adult moths

Prairie Pest Monitoring Network launches website

The resource will help farmers and agronomists scout and identify pests

The Prairie Pest Monitoring Network (PPMN) has launched a new website. The PPMN is a Prairie-wide insect pest monitoring group that provides valuable information, predicts insect risks, monitors insect populations and offers information to growers and agronomists to help them scout for pests, time their scouting activities and to make decisions about using chemical controls. “We are really excited to be launching this new website,” said Meghan


Manitoba fields display the colour spectrum of armyworm larvae colouration.

Armyworm on the march in Manitoba

Cereals and grasses are taking a hit from armyworms, one of several pests that tend to blow in as adults from the south

Manitoba has an armyworm problem. Eastern, central and southwestern Manitoba, as well as the Interlake have all reported spraying from farmers looking to keep the pests from chomping down on their cereal and forage grasses, according to Manitoba Agriculture and Resource Development. “There’s been some control in pretty much every agricultural region except the northwest,” provincial entomologist

Prairie pest report says grasshopper risk low

Prairie pest report says grasshopper risk low

This despite general upward trend in the populations across Manitoba and Saskatchewan

This year’s grasshopper threat remains light to very light across Manitoba, according to survey data released by the Prairie Pest Monitoring Network on April 27. The data is based on surveys done in 2019. These included nearly 3,200 grasshopper counts across the Prairie provinces between May 1 and August 31. Maps in the report show
