No outstanding insect damage to wheat was reported this season. In Daniels 

 and Sheridan counties there was a small outbreak of pale western cutworm that 

 destroyed about 1,000 acres. A native insect, the western wheat-stem sawfly, was 

 reported from Valley County. This insect is of considerable importance in the 

 wheat-growing sections of Canada so it will bear watching here. The western wheat 

 aphis was more abundant this year than it has been for years.
