WHEAT MIDGE INFESTATION OF SPRING CEREALS IN NORTHEASTERN SASKATCHEWAN
1987
Annual canarygrass and oats were found to be free of natural infestations of wheat midge (Sitodiplosis mosellana Gehin) in northeastern Saskatchewan. Six-row barley cultivars had low infestations and triticale, rye, wheat and durum wheat, high levels of infestation. Differences among susceptible cultivars were frequently due to asynchrony of plant susceptibility and midge oviposition.Key words: Sitodiplosis mosellana Gehin, wheat midge, cereals, cultivars
