The wheat midge model indicates that midge larvae should be at the soil surface this week. However, sub-optimal rainfall amounts may result in delayed emergence of adults.
Information related to wheat midge biology and monitoring can be accessed by linking to your provincial fact sheet (Saskatchewan Agriculture or Alberta Agriculture & Forestry). A review of wheat midge on the Canadian prairies was published by Elliott, Olfert, and Hartley in 2011.
