CONTROL OF GIPSY MOTH BY FOREST MANAGEMENT. 49 



Throughout the infested region much may be expected from out- 

 breaks of the wilt disease and the gradual subsidence of the gipsy 

 moth to a normal place among other injurious insects. 



To control the moth in many of the stands of the mixed-hardwoods 

 type of the white-pine region, spraying and creosoting must be used, 

 while birds, parasites, and insect enemies must do their part. 



In severe infestations forest management may be less expensive 

 than spraying and creosoting and has the advantage of being con- 

 structive instead of merely palliative, but it can not be recommended 

 as a method of relief for general indiscriminate application by States, 

 cities, towns, and private owners of woodlands throughout the infested 

 region.
