● Manitoba's Insect and Disease Update for 2017 is prepared by John Gavloski and Pratisara Bajracharya and read Issue #13 (posted August 16, 2017) noting soybean aphids as field near the R6 stage and high levels of bertha armyworm larvae from some fields in western Manitoba.
● Saskatchewan's Crop Production News - 2017 - Issue #6 includes an overview of late-season insect pests (bertha armyworm, diamondback moth, thistle caterpillar, soybean aphid, cabbage seedpod weevil, pea leaf weevil emerging flea beetles and grasshopper surveying) and Pre-Harvest Intervals (PHI) as well as important monitoring information for bins.
● Watch for Alberta Agriculture and Forestry's Call of the Land and access the most recent Insect Update (August 24, 2017) provided by Scott Meers. That report describes wheat stem sawfly surveying underway that scouts for cut stems to assess risk for 2018, white fluff balls at the top of canola that are actually parasitoid puparia or soon-to-be beneficial wasps that attack then emerge from a lepidopteran host, and the emergence of new-season red turnip beetles that will overwinter this fall.
