Good News for Wheat: Less Midge

A soil survey conducted last year shows fewer overwintering wheat midge larvae for the 2009 season, according to Janet Knodel, North Dakota State University Extension Service entomologist.

"The 2009 forecast for wheat midge populations continues to be favorable for North Dakota wheat producers," she says. "Overall, the wheat midge risk is lower than in 2008. Wheat midge populations ranged from zero to 286 midge larvae per square meter, with most of the state having less than 200 midge larvae per square meter during 2008."

There are two small pockets of 201 to 500 midge larvae per square meter in northwestern Divide and central Ward counties. Areas with more than 200 midge larvae per square meter should be scouted to determine if an action threshold population level exists. However, these areas are not considered high risk (more than 1,200 midge larvae per square meter).

The wheat midge survey was conducted by the NDSU Extension Service and supported by the North Dakota Wheat Commission.
