Respite from the ‘lady bugs?’

There were fewer aphids in Manitoba crops this year so Asian lady beetle populations should drop too

By Allan Dawson August 29, 2018

Those pesky Asian lady beetles, the bane of rural Manitoba homeowners, aren’t expected to be nearly as plentiful this fall because there haven’t been as many aphids for them to feed on, says Manitoba Agriculture entomologist John Gavloski. “The ladybird beetles were abundant last year because they had lots of food,” he said in an

Wheat Streak Mosaic Virus has been detected in the Wawanesa area (read more below) and Fusarium Head Blight (FHB) Risk Maps area also now available. Flea beetles in canola, and cutworms continue to be the main insects of concern. A hatch of the potential pest species of grasshoppers has started, but so far levels are quite low.

Canola under pressure from cutworms, flea beetles

Manitoba Insect & Disease Update summary for June 1

By Manitoba Agriculture Food and Rural Development June 3, 2016

Insects Cutworms and flea beetles on canola continue to be the insects of greatest concern. The cool, damp weather from the last few days would have slowed cutworm feeding, and the soil moisture, where not excessive, may help the plants compensate for feeding. Cutworm levels are quite variable, hard to find in some fields, more

Manitoba potato growers brace for wireworm issue

The loss of Lindane then Thimet has resulted in growing and booming wireworm populations across Canada

By Julienne Isaacs May 26, 2016

A budding wireworm problem for Prairie potato growers is the result of losing two key chemical control products. According to Bob Vernon, a research scientist with Agriculture and Agri-Food Canada in Agassiz, B.C., that lack of control options makes it a question of when, not if, the problem shows up. First the organophochlorine pesticide Lindane

Summary Scout cereal crops for rusts, and consider whether fusarium is a risk. Insect feeding has been minimal in cereals, however watch for signs of feeding or larvae of cereal leaf beetle so we can assess levels of parasitism if these are present. In canola, flea beetles are becoming less of an issue as canola

In addition to flea beetles, farmers should be scouting for cutworms, wireworms and grasshoppers

By Allan Dawson June 6, 2014

Flea beetles are munching on Manitoba canola crops but a provincial entomologist says the damage may look worse than it is. If there’s more than 25 per cent feeding damage after the canola crop has been planted for at least three weeks, an insecticide application could be economic, John Gavloski said in a Manitoba Agriculture,

Potato beetle resistance brewing in Manitoba fields

Farmers should be scouting early in the season and switching to  alternative products if they suspect resistance

By Gord Gilmour March 18, 2014

Andrew Ronald has spent a lot of time in recent months talking to Manitoba potato growers about a familiar pest problem that could soon be taking on a new prominence. The Keystone Potato Producers Association agronomist says there’s growing evidence that Colorado potato beetle — the most significant insect pest of potato crops in Manitoba

Scientists have recently figured out how the Asian lady beetle has so rapidly overtaken native beetle populations in Europe and North America. Researchers from the University of Giessen and the Max Planck Institute for Chemical Ecology in Jena, Germany say the Asian beetle is capable of infecting its competitors with a deadly parasite.

A report published online on January 24 in Current Biology, shows that even on the darkest of nights, African ball-rolling insects are guided by the soft glow of the Milky Way. While birds and
