Flea beetle damage ‘moderate’ across Prairies so far

Levels in Manitoba hit thresholds for spraying, reseeding canola

MarketsFarm — Flea beetles, cutworms and diamondback moths are only a few of the pests Prairie farmers have to deal with — and this year, so far, damage from flea beetles and cutworms has varied, as have moth counts. “Flea beetles are common throughout the Prairies, everywhere we grow canola. We haven’t been able to […] Read more

By controlling grasshoppers in the nymph stage, you can keep them from feasting on your fields later on when they reach adulthood.

Higher grasshopper nymph populations expected this spring in Manitoba

Manage nymphs in hatching areas before they disperse into crops

It’ll come as no surprise to Manitoba producers that the major pests to watch for this coming growing season are flea beetles in canola as well as grasshoppers and cutworms across all Prairie crops. All three are well established in Manitoba, all three overwinter in the province and all three showed high populations last year. […] Read more

Expect flea beetle and cutworm issues in Alberta fields

Grasshopper population levels will depend on weather, for one

Spring is finally coming to Alberta crop fields. Unfortunately, insect pests won’t be far behind. Weather, natural population cycles and wind conditions are just a few factors influencing insect pest numbers this season. Grasshopper Alberta is home to 85 species of grasshoppers, three of which caused economic damage to Alberta fields last year. In the […] Read more

Saskatchewan bugs to watch for in 2019

Low survey results in 2018 could be good news for Saskatchewan farmers this season

The 2018 pest survey results for Saskatchewan look like good news for the 2019 season. Grasshopper, pea leaf weevil and diamondback moth populations were all low in 2018. Large numbers of Bertha armyworm moths were caught in the Outlook and Watrous areas, but these do not necessarily predict 2019 populations. Saskatchewan Ministry of Agriculture integrated […] Read more


Tetrastichus julis, a parasitoid wasp whose larvae develop within cereal leaf beetle larvae can kill a substantial number of cereal leaf beetle larvae.

Beneficial insects versus four major pests

There are more than just pests in 
those sweep nets; don’t sweep it all away

Many insect pests feed on cereal crops and canola. But for every pest in the field, there are dozens of predators feeding on them. Knowing which beneficial insects feed on the major pests can help growers make better management decisions. University of Toronto postdoctoral entomologist Vincent Hervet explains. 1. Cereal leaf beetle The cereal leaf […] Read more

Brent called in early July about his canola crop after he found insect feeding damage on the plants’ leaves and oldest pods.

Crop advisor casebook: What’s causing the shot hole damage to these canola leaves?

A Crop Advisor's Solution from the June 5, 2018 issue of Grainews

Brent, a Saskatchewan producer, owns a 10,000-acre grain farm near Torquay, which is located about 16 kilometres north of the Canada-U.S. border. Brent called me in early July about his canola crop after he found insect-feeding damage on the plants’ leaves and oldest pods. “I might have a bertha armyworm problem in my canola crop,” […] Read more


The diamondback moth is capable of producing as many as four generations each year. The earlier they arrive and the better the conditions, they more they reproduce.

Why was 2017 an unprecedented year for diamondback moth?

Reviewing economic thresholds and 
action plans to control this insect pest

Last year’s growing season was a freakish one for diamondback moth in Western Canada, and while the probability that an outbreak of this calibre will be seen in 2018 is very low, the possibility is always there. Knowing what to do and when to act can help you to get this insect pest under better […] Read more

Want better insect surveys? Here’s how you can help

Provincial entomologists are looking to widen their insect survey networks

Every year provincial entomologists hit the fields, setting pheromone-baited traps and monitoring insect activity. Your help with these projects could improve the information available in your region. Alberta Alberta Agriculture and Forestry insect management specialist Scott Meers relies on growers. “We have large areas to cover, so when we get input from growers and agronomists […] Read more


Genetically modified diamondback moth offers pest control hope

London | Reuters –– Scientists in Britain say they have developed a way of genetically modifying and controlling an invasive species of moth that causes serious pest damage to cabbages, kale, canola and other similar crops worldwide. In what they said could be a pesticide-free and environmentally-friendly way to control insect pests, the scientists, from […] Read more
