the Atlantic Coast States was extremely effective in controlling a 

 very serious outbreak of the potato aphis. 



Nine special field agents are engaged in extension work in the con- 

 trol of deciduous-fruit insects, one agent being located in each of the 

 following States: Washington, Oregon, Texas, Indiana, Kansas, 

 Mississippi, Virginia, Ehode Island, and North Carolina. These 

 agents have closely associated their work with that of the county 

 agents, putting on demonstrations, assisting in sprayings, advising 

 fruit growers, and giving lectures. In addition to this work, eight 

 entomological inspectors have been employed in survey work to de- 

 termine the territory covered by the recently introduced oriental 

 peach moth. 



Three agents in California and one in Florida are carrying on ex- 

 tension work in the control of citrus-fruit insects. The work in Cali- 

 fornia has been very largely devoted to teaching methods of destruc- 

 tion of the Argentine ant, which incidentally will control certain of 

 the mealybugs attacking citrus fruits. 



Three agents are covering the entire lower Mississippi Valley, 

 teaching methods of control of insects affecting poultry and cattle. 



An average of six special field agents has been maintained in the 

 field teaching modern methods in beekeeping. Work has been car- 

 ried on in 34 States along this line, and the field agents have ad- 

 dressed nearly 25,0(>0 beekeepers and have visited 1,198 apiaries to 

 give personal instructions. In addition to this they have organized 

 84 county beekeepers' associations in the several States. 



In all, the bureau's agents have held 338 conferences with county 

 agents, extension directors, State entomologists, and others to further 

 this work; they have put on 894 demonstrations where practical 

 methods of insect control were actually used before growers and live- 

 stock men; they have visited 5,828 farmers to give personal advice 

 on entomological questions, and have delivered 1,366 lectures before 

 audiences amounting to 90,385 persons. 



The bureau's representative in this work is cooperating with the 

 States Relations Service by making an annual inspection of all States 

 carrying on Smith-Lever fund work in entomology, with a view of 

 improving and correlating the efforts in entomological extension work. 



Another activity of this office has been the work in connection with 

 the Bureau of Entomology's exhibits. This year an exhibit consist- 

 ing of 10 screens, one screen to illustrate the activities of each of 

 the bureau's research offices, has been prepared. These screens each 

 contain eight bromide enlargements of the important pests, their 

 ravages, and the methods for their control. This exhibit is part of 

 the large interdepartmental exhibit which was displayed at 32 of the 

 State fairs throughout the country. The motion-picture activities 

 of the bureau have been arranged for in connection with the work 

 on exhibits, and several films have been prepared.

Cooperative arrangements have been made with the entomologists 



of the various agricultural colleges and experiment stations, with 



the teachers of entomology in the other colleges and universities, 



with the field workers of the Forest Service, with the county agents
