area. A special account has been prepared which will be pub- 

 lished as an extension bulletin by Cornell University and well dis- 

 tributed throughout the infested area in an effort to secure general 

 cooperation in checking this pest until such time as natural enemies 

 may bring it under control or experience shows it to be an insect 

 of comparatively minor importance. 



Work on the codling moth was continued in cooperation with 

 the bureau of horticulture of the State Department of Agriculture. 

 The spraying operations were continued in the orchard of H. E. 

 Wellman, Kendall, and, owing to unfortunate weather and field 

 conditions, the results, as will be seen by a reference to the detailed 

 account of the work, were not satisfactory. The very cool, wet 

 weather of early spring appears to have prevented the setting of a 

 fair crop of fruit and in many portions of the western part of the 

 State there were almost no apples. The yields on the experimental 

 plots, though promising well at blossoming time, were so small that 

 it was not considered worth while to pick and classify the fruit on the 

 trees sprayed three times, owing to the fact that the crop was so 

 small that very little of value could be secured. These untoward 

 conditions were further accentuated by the extremely muddy con- 

 dition of the orchard at the time of the first spraying. This materially 

 affected the efficiency of the work. The experiment in Niagara 

 county was continued in the orchard of George Mead of Barker and 

 there conditions were much better than in the Kendall orchard, since 

 there was a larger crop and fairly satisfactory returns were obtained 

 from the spraying, though the benefit secured was not nearly so 

 great as that which had been obtained in earlier years in the Hudson 

 valley. The small crop of fruit mentioned above was also accom- 

 panied by an unusually heavy infestation by codling moth and the 

 two combined prevented obtaining high percentages of worm-free 

 fruit, though substantial benefits were secured on the sprayed trees, 

 as compared with the unsprayed or checks. 



Apple maggot. The work of last year with this pest was con- 

 tinued in the orchard of Edward Van Alstyne of Kinderhook. The 

 test made with the late application of a poison just as the flies began 

 to appear was followed by a very gratifying freedom of injury on 

 trees where there was very serious damage to the fruit last year. 

 Variations in the numbers of this insect are so great that we do not feel 

 warranted in expressing definite conclusions from the results of one 

 season.
