Wheat Midge Wheat Midge Degree Day Update

The degree-day model (NDSU North Dakota Agricultural Weather Network website) indicates that 50-90% of the females have emerged and are flying. Scout for the orange flies at night when temperatures are greater than 59 F and the winds are relatively calm (less than 6 mph) during the heading to early flowering crop stages. This year we have had good soil moisture with the rains, which means favorable conditions for wheat midge emergence. See Crop & Pest Report #9, July 2, 2015 for more information on scouting for wheat midge.
