Forest Insect and Disease Protection (cont^d) 



In addition, research programmes carried on by the Division of 

 Forest Biology, Dominion Department of Agriculture, received our constant 

 attention. Of particular and immediate concern are the chemical control experi- 

 ments, concerned with the European pine shoot moth, carried on at Northumberland 

 County Forest in the Lindsay district and the research pro;Iects concerned with 

 the spruce budworm carried on at field stations in the Port Arthur and Kenora 

 districts. 



The discovery of the pine root collar weevil in the Lake Simcot 

 district was of particular interest since no previous record of this insect's 

 presence in Ontario is recorded o Detailed biological studies supplemented by 

 a chemical control project of an experimental nature were immediately initiated 

 and will continue until a satisfactory solution is found. 



The field staff of this Department continued to contribute to 

 the Forest Insect and Disease Survey, a project of the Division of Forest 

 Biology (Canada). 



The introduction of more intensive management practices through- 

 out the Province has emphasized the increasing importance of the biological 

 phase of forest protection activities.
