preliminary study will be made of the biology and habits of the spear- 

 marked black moth. The effect of defoliation on the white birch stands 

 will be studied and' possible control measures investigated. 



Cooperative Forest Insect Survey 



The detection and reporting of forest insect-caused damage in Alaska in- 

 volves a tremendously vast forested area with relatively few land man- 

 agers. To facilitate the collecting of information on forest pests, a 

 cooperative forest insect survey or reporting system has been establish- 

 ed. Under this system all forest land managers in Alaska are urged to 

 report any unusual forest insect activity to the Alaska Forest Research 

 Center in Juneau which acts as a clearing house for this information. 

 An entomologist at the Research Center evaluates the reports and deter- 

 mines the need, if any, for further action. Where further action is 

 indicated, an aerial or ground inspection of the infested area is 

 usually made. This may involve a reconnaissance or, if more detailed 

 information is required, an appraisal survey. These surveys are intend- 

 ed to determine the extent, the present status, and the probable future 

 trend of the infestation and possible control or preventive measures 

 that might be employed. The information from these surveys is forwarded 

 to the responsible land management agencies for further action. 



Providing training and maintaining a current interest in the program is 

 accomplished through personal contacts in the field between land 

 managers and forest entomologists. This is aided by occasional group 

 training sessions.
