To the Honorable the Regents of the University of the State of New 

 York : 



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

 Sixth Report on the Injurious and Other Insects of the State of 

 New York. 



I have again the privilege of recording the exemption of the 

 crops of the State from any widespread serious insect attack, and 

 a mitigation of some of the more formidable ones of preceding 

 years. 



Injuries to cereal crops have been remarkably few and local. 

 While in several of the other States, as notably in Ohio, Indiana, 

 and Illinois, the grain-aphis, Siphonophora avence (Fabr.) has been 

 unusually destructive to wheat, oats and other of the grains, and 

 it has also appeared in injurious numbers in New Jersey and in 

 Pennsylvania, not a single instance of its occurrence in the State 

 of New York has been reported to me. 



The hop-aphis, Fhorodon humuli (Schrank), which was the 

 occasion in 1886 of almost the entire destruction of the hop crop 

 of the State, again appeared during the month of July in the hop- 

 yards of Schoharie and Montgomery counties in such numbers as 

 to excite great alarm. Recommendation was made by the Ento- 

 mologist and circulated through the local press, of earnest effort 

 to arrest the attack in its then existing stage, by promptly and 

 thoroughly spraying the infested vines with insecticidal washes; 

 but fortunately this measure, attendant with considerable labor, 

 was not found necessary, for the heavy rains that set in at the 

 time, and continued for weeks thereafter, proved fatal to most of 

 the hop-lice, and speedily rescued the crop from its threatened 

 destruction. 



In neglected orchards — in which category most of the orchards 

 of our State find place — fruit insects have abounded to the 

 extent that the fruit gathered, carried to market and sold, has, in
