REPORT OF THE STATE ENTOMOLOGIST 



The State Entomologist reports that the past season was note- 

 worthy because of the superabundance of the common apple 

 tent caterpillar in the Hudson and Mohawk valleys and on the 

 borders of the Adirondacks. The pests were so numerous that 

 most of the wild cherries on the roadside were defoliated and 

 many orchards severely injured. There were records of local 

 damage here and there by the allied forest tent caterpillar ; in several 

 sections extended tracts were stripped of foliage. There is at

 season and possibly causing serious injury locally. The green maple 

 worm, so numerous last year, attracted no attention the past season. 



Petroleum compounds as insecticides. Dead and dying trees

 preceding autumn with a commercial preparation of petroleum,
