Weekly Update (Aug 17, 2017; Wk 16) - Provincial Insect Pest Reports

Provincial entomologists provide insect pest updates throughout the growing season so we have attempted to link to their most recent information: 

● 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 #5 includes information related to value of late-season disease scouting and record keeping, critical periods for crop water use, and leaving tall-stubble at harvest.

● Watch for Alberta Agriculture and Forestry's Call of the Land and access the most recent Insect Update (August 17, 2017) provided by Scott Meers. That report notes that diamondback moth are starting to pupate in central and southern fields in the province yet late canola may still need monitoring for DBM larvae, bedstraw hawkmoth larvae (~2.5" long) have been spotted in canola feeding on volunteer cleavers, the beginning of post-harvest survey for wheat midge and wheat stem sawfly across the province, plus the Agricultural Fieldmen are now ~30% completed the annual grasshopper survey with data coming in already.
