Doings of Societies. 



The twenty-second annual meeting of the American Asso- 

 ciation of Economic Entomologists was held at the Harvard 

 Medical School, (Brookline) Boston, Mass., December 28 

 and 29, 1909. The first session was called to order by Presi- 

 dent W. E. Britton, of New Haven, Conn., who presided 

 throughout the meeting and who delivered the annual address 

 on "The Official Entomologist and the Farmer." The program 

 was crowded with papers which were of great economic im- 

 portance to the entomologist and the agriculturist, although a 

 few were more technical in character and dealt with some of the 

 fundamental principles of scientific investigation of entomolog- 

 ical matters. A discussion of different methods used in re- 

 search work was of particular interest, as were also the reports 

 of the progress that is being made in the field and parasite 

 work in New England for the purpose of controlling the gypsy 

 and brown-tail moths. A report by Dr. W. P. Headden, of 

 Colorado, concerning the injury to fruit trees caused by arseni- 

 cal spraying and the discussions that followed brought out 

 many new ideas on this important subject. An exhibit made 

 by the local entomologists and members which was held in an 

 adjoining room contained samples of apparatus and breeding 

 devices, as well as insect collections, which added much interest 

 to the meeting. On Tuesday evening the association and the 

 Entomological Society of America were the guests of the Cam- 

 bridge Entomological Club, and on Thursday morning the 

 members had the opportunity of witnessing a spraying demon- 

 stration at Arlington with high-power sprayers, as the guest > 

 of Mr. H. L. Frost. 



The attendance at each session numbered over 100 members 

 and visitors, nearly every section of the United States and 

 Canada being represented.
