INSECT DAMAGE TO SEEDS OF PACIFIC COAST CONIFERS. 7 



area is infested by these insects. In the collection and cleaning of 

 forest seeds there is opportunity for use of the information which is 

 now being gathered on this subject. An intelligent selection of the 

 seed-collecting areas will prevent much of the loss due to gathering 

 seed which is afterwards found to be infested or worthless. 



A count of the number of infested cones and of damaged seeds will 

 give a clue to the percentage of damage in the crop. Whether or 

 not the damage is sufficient to make collection of the seed unprofitable 

 on the area will have to be determined by the collector.
