Weekly Update (Jul 27, 2017; Wk 13) - 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 #10 (posted July 26, 2017) noting diamondback moth exceeding economic thresholds in some fields within the southwest and Gladstone areas, cereal aphids and soybean aphids plus the appearance of green cloverworm in some eastern Manitoba soybean fields.

● Saskatchewan's Crop Production News - 2017 - Issue #4 includes information related to soybean pests prepared by Joel Peru. That report includes an update on scouting and management tips for painted lady butterflies (also described in Week 6) and Aphanomyces root rot. 

Additionally, Danielle Stephens with Sask Ag reported that bertha moth counts in pheromone traps appears to have peaked over most areas of Saskatchewan during the week of July 17th. Cooperators operating BAW traps are asked to take down their traps the week of August 2nd and to submit their counts but also thanked for their ongoing support which makes the 2017 map possible.
● Watch for Alberta Agriculture and Forestry's Call of the Land and access the most recent Insect Update (July 27, 2017) provided by Scott Meers. That reports notes surveying is underway targeting a 'new' midge in canola, continued scouting needed for diamondback moth with larval populations exceeding thresholds in a few canola fields at early pod stages in southern Alberta, appearance of low numbers of wheat leaf miner which is typically an occasional pest but seems to be accompanied by its parasitoid by K. Fry this year.
