In his weekly Call of the Land interview, Alberta Agriculture insect specialist Scott Meers says wheat midge are now emerging across the province. “Interestingly enough, they’re actually coming out first in the Peace and just this week they’re starting to come out across the rest of the province,” Meers said.
Recent warm weather should mean a fairly sharp peak of emergence, which will make it easier for management, he said.
Meers said that parasitoids of wheat midge are being collected in the Willow Creek area, where producers are no longer spraying because high populations are “doing a really good job of holding the population down.”
Cabbage seedpod weevil and cereal leaf beetle numbers are lower than in previous years, and Meers said there are reports that parasitoids are also helping keep cereal leaf beetles under control.
