The Predicted Wheat Midge Development storymap provides weekly predicted stages of development of the wheat midge (Sitodiplosis mosellana), across Western Canada. The wheat midge is found in most areas around the world wherever wheat is grown. In recent years, significant damage to wheat crops due to wheat midge has been reported in Alberta, Saskatchewan, Manitoba, and southern British Columbia.
These maps and datasets provide an estimation of the developmental stage of the wheat midge across Western Canada in order to equip producers with information on what may be occurring in their area. This information is particularly important when timing scouting activities in mid-summer to ensure populations are managed before oviposition occurs.
