FOKEWOIM). 



November 30, 1915. 



The summer just passed has witnessed an outbreak of the work of the 

 bean-maggot such as has never before been experienced in Michigan. To 

 partially compensate for the serious losses sustained, however, the out- 

 break has offered an opportunity for gathering data of importance which 

 seems to justify the publication of this circular. The observations made 

 by Mr. Don B. Whelan are offered, therefore, in the hope that advantage 

 may be taken of them during the coming senson. 



Respectfully submitted, 



R. H. PETTIT, 

 Entomologist of Experiment Station.
