Insect Pests
A research scientist at Agriculture and Agri-Food Canada in P.E.I is investigating natural ways to deal with pests that damage cabbage, canola and potatoes. 
Armyworm has been spotted at low levels in winter wheat fields, increasing the need to scout for this pest in spring cereals and mixed forages.
Cabbage seedpod weevils (CSW) are being found in spring canola, and the key to protecting your crop yield is to prevent adult CSW from laying eggs in newly formed pods.
Flea beetles and cutworms continue to be the main insect concerns, according to John Gavloski in the latest Manitoba Insect and Disease Update. Foliar insecticide applications are occurring in many canola fields and some second insecticide applications to control flea bettles. There are also more reports of reseeding of canola because of…
With the loss of effective insecticides (e.g. lindane), wireworms have re-emerged in recent years as primary pests of potato, cereals and vegetables. Wireworms are the soil-dwelling larval stage of the click beetles (Elateridae). In this Insect of the Week, learn more about identification, scouting and management options. | READ MORE
First cut took place on most of the forage acres in southern Ontario. Though this is an effective way to manage alfalfa weevil, this year the larvae were quite small at the time of cutting, writes Tracey Baute in her latest Baute Bug Blog on FieldCropNews.com. | READ MORE
Seedling disease is showing up in early planted soybeans, and flea beetles are a concern in many canola fields, according to John Gavloski in the latest Manitoba Insect and Disease Update. 
With planting delayed briefly due to rain, it is the perfect time to get out and set up some wireworm bait stations. Soil temperatures are quite warm now and recent University of Guelph Ridgetown Campus research has found that spring is the better time to successfully bait for wireworms. Tracey…
Specialists at Alberta Agriculture and Forestry (AF) are working to have fields predetermined for the 2018 insect survey season and are looking for assistance from agrologists and producers across Alberta. This year, the survey teams would like to check pea and wheat fields. They will survey for pea leaf weevil…
Cabbage seedpod weevil is an invasive insect pest of canola. Originally found in Europe, the insect proliferated in the United States and was first confirmed in Alberta in the mid-1990s.
A midge by any other name is still a midge – but it’s not swede midge. That’s the finding of scientists with Agriculture and Agri-Food Canada (AAFC), University of Guelph and the Canadian Food Inspection Agency (CFIA). Swede midge had been confirmed by CFIA in 2007, but what had previously…
Cutworms are present across the Prairies, and in some years some species of cutworms can reach levels that are of economic concern in field crops. The focus of a five-year project conducted across the Prairies resulted in the development of better identification tools, a better understanding of cutworm biology and…
Cutworms are a complex of several pest species that affect multiple crops grown in Canada. A few species can cause economic damage in cereal and oilseed field crops. Researchers are working to find efficient monitoring tools that can determine distribution of cutworms and alert growers to impending outbreaks, while excluding…
The alfalfa weevil (Hypera postica) is turning into a bigger challenge for some alfalfa growers. Populations of the insect pest in the Rosemary area of Alberta (about 170 kilometres east of Calgary, near Brooks) have been confirmed as resistant to the Group 3A synthetic pyrethroid insecticide Matador. By extension, those…
Figuring out how to fight a fairly new pest, like the western bean cutworm (WBC), is a bit like preparing to face off against a new sports opponent. “If you’re going to compete in a sport, the best thing to do is study your opponent’s strengths and weaknesses, and then…
