Cutworms, flea beetles a concern for canola growers

Manitoba Insect & Disease Update for May 25

By
Insects Cutworms and flea beetles on canola are the insects of greatest concern currently. Seed treatments should still be effective against flea beetles in most canola fields, although scouting for feeding damage is encouraged, especially in the earlier seeded fields where seed treatments may soon start losing effectiveness. Cutworm levels are quite variable, hard to

Manitoba potato growers brace for wireworm issue

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

By
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

Flies, worms, crickets crawl onto EU policy-makers’ menu

Insects are more likely to serve as an animal feed than as food

By
Houseflies, crickets and silkworms can be safe, nutritious and more environmentally friendly alternatives to chicken, beef or pork, research carried out for the European Commission finds. Still, they are less likely to be found on European restaurant menus than in animal feed, carefully controlled to prevent the kind of prions, or abnormal proteins, blamed for

Genetically modified diamondback moth offers pest control hope

The modified moths can mate as well as any other but they only produce male offspring


By
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 the Oxford University

Summary of crop insects on Manitoba crops in 2014

Information intended to be useful for winter planning, preparations for next season

By
A “Summary of Insects on Crops in Manitoba in 2014” is now posted on the MAFRD website. This report is based partially on observation by myself and my summer assistant. A large part of this information, however, is based on observations and reports from farm production advisors, agronomists, farmers, and others who contributed information over

Plants can hear the difference

They respond differently to vibrations caused by 
chewing insects than to wind

By
University of Missouri-Columbia – Researchers at the University of Missouri-Columbia have found plants can not only tell the difference between the sound waves caused by insects chewing and wind but they respond with more defences. ‘We found that feeding vibrations signal changes in the plant cells’ metabolism, creating more defensive chemicals that can repel attacks

Later canola seeding could mean less flea beetle damage

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

By
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,
