Assessing the impacts of natural enemies and canopy structure on orange wheat blossom midge, Sitodiplosis mosellana (Diptera: Cecidomyiidae), in the Peace River region of Alberta
Orange wheat blossom midge, Sitodiplosis mosellana, is an invasive, economically important pest in spring wheat in the Canadian Prairies. In the Peace River region of Alberta, little is known about this pest and its natural enemies. Impacts of crop type and canopy structure on assemblages of carabid...
