ENTOMOLOGICAL ADDRESSES. 



REPORT OF THE COMMITTEE ON ENTOMOLOGY. 



[Read before the Western New York Horticultural Society at its Annual Meet- 

 ing, January 29th, 1891.] 



The Committee on Entomology beg leave respectfully to report: 

 It is gratifying to be able to report not only continued, but a marked 

 accelerated progress in this department during the past year. It is 

 safe to say that greater attention has been given to insects than in any 

 preceding year. Large collections have been made; many new species 

 have been described; life-histories have been worked out; experimen- 

 tation in methods of controlling injurious species has been earnest, 

 extended, and successful; and publication of these labors and results 

 has been placed in the hands of the student and the agriculturist. As 

 illustrating the growing interest manifested in this branch of study, we 

 may state that, while in former years, far more attention had been 

 given to plants than to insects, a recent report of Director Atwater, of 

 the Office of Experiment Stations, at Washington, gives as the number 

 pursuing entomological investigations at the different stations, at that 

 time (1890) as twenty-nine, as against thirty engaged in botanical stud- 

 ies. From so large a corps of earnest entomologists, generally distri- 

 buted over the United States, and vying with one another to produce 

 the best results, what may we not expect for the future of economic 

 entomology. 



Of the progress which we have mentioned, most of it has been in a 

 practical direction, — in methods of control of insect pests. Prominent 

 among these, and, therefore, the first to which we will refer^ we will 

 name 



Spraying with Insecticidbs. 



Efect of London purple on the plum. — At the last annual meeting 

 of this Society it was stated by one of the members, in discussion, that 

 he had nearly ruined a plum orchard by spraying it with a pound of 

 London purple in three hundred gallons of water, for, as the; result of 

 spraying, every leaf fell from the trees. In the report of the recent 

 meeting of the Ontario Fruit Growers' Association, this statement from
