Forecasting for insect pests on the Canadian prairies - a Saskatchewan perspective
There are a number of insect pests that represent potentially serious economic threats to agricultural producers on the Canadian prairies. Integrated Pest Management (IPM) is a long term approach to maintain pest densities below an economic level and help to reduce pesticide use. However, part of the overall strategy is being prepared to intervene with reactive measures if infestations reach significant proportions. Pest population densities, their distribution within the Province and timing of their emergence within a crop are estimated through surveys, monitoring programs and forecasts that are conducted annually by Saskatchewan Agriculture and Food, Saskatchewan Crop Insurance and other agencies. In addition, the Tri-provincial Monitoring Group, coordinated out of A.A.F.C., Saskatoon, uses Saskatchewan, Alberta and Manitoba insect data and Environment Canada data to provide a prairie-wide view of insect pests and environmental effects The main programs focus on Orange Wheat Blossom Midge, grasshoppers, Bertha Armyworm, and Diamondback Moth.
