REPORT OF THE ENTOMOLOGIST. 



To the Director of the Cornell University Agricultural Experi- 

 ment Station : 

 Sir, — As the Entomological work of the Station has been per- 

 formed during the past year almost entirely by the Assistant Ento- 

 mologist, I have requested him to prepare a report on it, which I 

 herewith transmit. 



Very respectfully yours,

 Experiment Station : 



Sir. — During the past year the Entomological Division of the 

 Station investigated a new insect pest of the cherry, which did 

 much damage to this fruit in our State. The insect infests the fruit, 

 and there is usually uo indications of its presence until the ripe and 

 luscious fruit is being prepared for canning or for the table. The

 and it will apparently prove a serious pest and one very difficult 

 to combat. The results of our investigations were published in 

 bulletin : 



No. 172. " The Cherry Fruit-Fly : A New Cherry Pest." 



Our extensive experiments against the peach-tree borer were prac- 

 tically concluded during the year and the results embodied in 

 bulletin : 



No. 176. " The Peach-tree Borer." 



An abridged edition of this bulletin was published for general 

 distribution. We expect to further test some of the methods dis- 

 cussed in the bulletin again this year, as it is claimed that our results 

 are not obtained with similar materials in other States ; for instance, 

 Missouri peach-growers assert that gas tar kills their trees, hence we
