21st REPORT OF THE STATE ENTOMOLOGIST 



1905 



To John M. Clarke, Director of Science Division 



I have the honor of presenting herewith my report on the 

 injurious and other insects of the State of New York for the year 

 ending October 14, 1905. 



General entomologic features. The season of 1905 was marked 

 by the appearance of two destructive grass pests. Grass webworms 

 (Crambidae) were very abundant and somewhat injurious to grass 

 lands in Rensselaer and Albany counties in early spring, and in 

 midsummer the army worm, H e 1 i o p h i 1 a unipuncta Haw., 

 amused considerable anxiety by appearing in numbers in limited 

 portions of Chautauqua and Erie counties. Fortunately this latter 

 attack was not extensive and the injury did not approximate that 

 inflicted by this species in 1896. The second brood of the codling 

 moth, Carpocapsa pomonella Linn., was unusually 

 abundant and caused serious losses, because the fruit crop was 

 light and prices for first quality fruit correspondingly high. The 

 rose beetle, Macrodactylus subspinosus Fabr., was 

 very abundant and injurious in some sections of the State, appear- 

 ing in swarms and nearly defoliating many fruit trees. The San 

 Jose scale, A 5 p i d i o t u s p e r n i c i s u s Comst, continues to 

 spread in fruit-growing sections though it has not been so prolific 

 as last year. Shade trees in some of the principal cities of the State 

 were seriously injured by caterpillars of the white marked tussock 

 moth, Ilemerocampa leucostigma Abb. & Sm., the 

 pests being so numerous as to defoliate thousands of trees.
