20th REPORT OF THE STATE ENTO- 

 MOLOGIST 1904 



To John M. Clarke, Director of Science Division 



I have the honor of presenting herewith my report on the inju- 

 rious and other insects in the State of New York for the year end- 

 ing Oct. 15, 1904. 



General entomologic features. The season of 1904 is notable 

 because of the remarkably small amoujit of injury to agricultural 

 crops. Plant lice and pear psyllas, Psylla pyricola Forst., 

 which were so abundant in 1903, hardly attracted attention last 

 season. The pernicious or San Jose scale insect has become firmly 

 established in certain localities in the State, and the best method 

 of controlling it in commercial orchards is an urgent problem. 

 The elm leaf beetle, Galerucella luteola Mull., has 

 been remarkable for its scarcity and the same is true of a con- 

 siderable number of the more common pests injurious to garden 

 and field crops. Even the grape root worm was much less numer- 

 ous in Chautauqua vineyards than in 1903. 



Office work. This has been continued as in preceding years, 

 and aside from the natural lack of inquiries due to the paucity 

 of insect life, indicates a most gratifying interest in our work. 

 The determination of scale insects for the commissioner of agri- 

 culture, in connection with the nursery inspection work conducted 

 by his department, has made some demands on the office. The 

 first assistant, Mr C. M. Walker, severed his connection with 

 this office Jan. i, and Mr D. B. Young was promoted to his posi- 

 tion. Mr Ivan L. Nixon, a graduate of the Kansas State Agri-
