To the Regents of the University of the State of New York : 



Gentlemen. — I have the honor of presenting" to your board my 

 Seventh Eeport on the Injurious and other Insects of the State of 

 New York, embracing results of studies and observations made 

 during the year 1890. 



The year has not been sig"nalized by any wide-spread and par- 

 ticularly injurious insect attack upon the agricultural products of 

 the state, or by the introduction from abroad of insect pests of 

 special economic importance, yet a large number of important sub- 

 jects of study have presented themselves, most of which have 

 received the attention due them, while of several the investigation 

 has not advanced sufficiently far to authorize their presentation at 

 the present time. 



May I briefly refer, as in former reports, to some of the more 

 interesting insect occurrences of the year, and to a few that seem 

 to call for their simple record while awaiting the fuller notice to be 

 given them hereafter. 



The apple-tree tent-caterpillar, Clisiocampa Americana Harris, 

 which has been noticed in the two preceding reports for its exces- 

 sive abundance and injury to the foliage of apple trees, has again 

 been destructive over a large portion of the state, but in a some- 

 what diminished degree. Its ravages are being more extensively 

 met by its destruction in its early stages, and by spraying opera- 

 tions later. Our orchardists are slowly awakening to the absolute 

 necessity of preserving the foliage of their trees from insect pests 

 and fungoid diseases, if fruit-growing hereafter is to be conducted 

 with profit. In this connection it may be proper to mention that 

 the almost entire loss of the fruit crop the past year over a large 

 part of the state is not attributable to insect injuries, but to a 

 concurrence of unfavorable seasonal conditions which resulted in, 

 or contributed largely to, various fungus attacks and unknown 

 maladies, from the effects of which blossoms blighted or the young
