49(1 Report of Farmers' Institutes 



Material assistance was given in Monroe County by Farai 

 Bureau Manager Toan, and in Orleans and Niagara counties by 

 Messrs. Buckholz and Strickland, experts in the Bureau of Plant 

 Industry, Department of Agriculture. 



The doctor undertook to work witb an open mind with the desire 

 to obtain facts; in addition to what was given on the subject at 

 the normal institute, which may be found on page 2417 of this 

 report. Dr. Felt has furnished the following comprehensive account 

 of his work and his findings : 



" SIDE INJURY " AND THE CODLING MOTH 



Dr. E. p. Felt, Albany, :N". Y. 

 State Entomologist 



The control of the codling moth is a problem of great practical 

 importance, to apple and pear growers especially, since investiga- 

 tions have shown that local climatic influences may modify the 

 development of the insect to a marked degree. 



Experiments in the Hudson Valley in earlier years gave remark- 

 ably satisfactory returns, and in 1915 a series of experiments were 

 planned by the entomologist in cooperation with the Bureaus of 

 Farmers' Institutes and Plant Industry of the State Department 

 of Agriculture and the Monroe County Farm Bureau. The experi- 

 mental orchards were located in Orleans, Monroe, and Niagara 

 counties, through the courtesy and cooperation of Messrs. J. A. 

 Talbot, of Spencerport ; H. E. Wellman, of Kendall ; and W. H. 

 Cowper & Son, of Newfane. In each case the men and the equip- 

 ment on the place were used, the entomologist supervising the 

 operations and being assisted by Messrs. A. B. Buchholz, of 

 Albion, and L. F, Strickland, of Lockport — both agents of the 

 State Department of Agriculture — and by Mr. L. A. Toan, man- 

 ager of the Monroe County Farm Bureau. As there were twenty 

 experimental trees in each orchard, some bearing as high as eleven 

 barrels, the manual labor involved in the classification of the yield 

 was by no means small. 



Investigations during the season showed that in many instances 

 20 per cent or more of the crop of the western apple section bore 

 the small and characteristic blemish produced by larvae hatching
