Weather synopsis – Below is the Accumulated Precipitation for the Growing Season

Wheat Midge (Sitodiplosis mosellana) – Update: Wheat midge pheromone traps and in-field monitoring results have been compared to different models predicting wheat midge development over the past two weeks. Staff at AAFC-Saskatoon are evaluating other base temperatures for their suitability in predicting wheat midge emergence North of 55°. This is in response to wheat midge observed during in-field monitoring and on pheromone traps throughout the Peace River region prior to the predicted emergence generated using the base 5°C model. The degree-day model proposed by German researchers (Basedow) may predict adult midge emergence better in the Peace River region compared to the 5°C base temperature model that previously corresponded well to midge emergence throughout central and southern areas of the prairies. The Basedow model has been mapped below using prairie-wide temperature data for the present growing season. Note that the map below predicts midge to emerge (as of July 21, 2014) in areas highlighted yellow, gold, and orange whereas the midge flight is predicted to be drawing to a close in areas highlighted red in the map below.
