THE APPLE MAGGOT. 



Trypeta pomonella, Walsh. 



PROF. F. L. HARVEY. 



(Prof. Harvey has, by nearly two years patient labor, the 

 results of which will appear in a more elaborate and detailed form 

 later, completely worked ont the life history of the apple maggot, 

 which is doing such immense injury to fruit in some parts of our 

 State. The practical points of his researches are herewith pre- 

 sented. In securing these results the Station has done its part of 

 the work. The fruit growers must do the rest. If the recom-

 universally followed for two years, there would be few traces of 

 the apple maggot left in the State. Concerted and vigorous

 of last season so supplemented and verified that we are now able 

 to announce all the steps in its complete life history. The details 

 of work by which these results were obtained will be fully consid- 

 ered and illustrated in a subsequent bulletin. The object now is 

 to give tersely the steps in the life history of the insect, call
