Landscape composition affected flea beetle abundance, as well as seeding rate, temperature, predator presence and the type of pest control option selected. “Integrated approaches for flea beetle control II: Incorporating the impacts of plant density, ground predators, and landscape-scale predictive models in the management of flea beetles in the Canadian Prairies,” Alejandro Costamagna, University of...

This study based in the Peace River region of Alberta showed that later seeding, higher plant counts and larger seeds reduce flea beetle risk to canola yield. “Evaluating the effect of canola seeding rate and seed size seeded into wheat stubble on flea beetle damage and population,” María Angélica Ouellette, North Peace Applied Research Association...

This project developed a reliable, pheromone-trapping system to monitor Contarinia brassicola, canola flower midge. “Monitoring the canola flower midge within pheromone-baited traps,” Boyd Mori and Kyle Van Camp, University of Alberta SaskCanola, Alberta Canola, Manitoba Canola Growers, Western Grains Research Foundation Read the full report on the Canola Research Hub. Canola flower midge, Contarinia brassicola,...

Parasitoid wasp T. perfectus demonstrated high levels of parasitism of cabbage seedpod weevil in Ontario and Quebec with minimum spill over into non-cultivated habitats. The insect did not appear to pose a major risk in the Prairies, suggesting it could work as a biological control option in Western Canada. “Feasibility of using Trichomalus perfectus for...

Keeping non-crop beneficial insect reservoirs – such as grass margins, treed areas, wetlands, and shelterbelts – near fields can help canola producers contribute to sustainability objectives while having a minimal (and possibly positive) impact on profitability and productivity. “Surveillance Networks for Beneficial Insects II: quantifying the canola yield effect of wetlands, shelterbelts and other insect...
