THIRTY-FOURTH REPORT OF THE STATE 
ENTOMOLOGIST 
1918 
Dr John M. Clarke, Director of the State Museum 
I have the honor to present herewith my report on the injurious and 
other insects of the State of New York for the year ending September 
320, TOL. 
The season of 1918 has presented many features in common with 
the abnormal spring andsummer of 1917. Therainfallin the western 
part of the State was not so great as last year and the injury then 
so generally attributed to the seed corn maggot was much less preva- 
lent, and limited very largely to the wetter ground. The develop- 
ments of both last year and this have shown that the seed corn maggot 
problem is largely a question of methods, the depth of planting and 
drainage being the more important factors and the insect injury 
largely a consequence of unfavorable conditions. 
The apple tent caterpillar was notable for its absence in most sec- 
tions of the State, particularly in portions of Dutchess county. 
The late leaf feeders, such as the red-humped apple worm and the 
yellow-necked apple worm were, as last year, exceptionally abun- 
dant, and there has been even more severe damage in Rensselaer and 
Columbia counties in particular. The fall webworm, the hickory 
tussock moth caterpillar and some related species were also uncom- 
monly numerous and destructive. 
Fruit tree insects. Reports from areas’ infested by the recently 
established apple and thorn skeletonizer indicate a moderate abun_
