kept up to date, and Entomology Current Literature has been issued 
bimonthly. 
The entomological exhibit in the patio of the administration 
building of the Department in April 1940 greatly stimulated popular 
interest in entomology, and the Bureau library has been consulted 
frequently ever since by high-school students and laymen seeking in- 
formation. Visits to the library have not only furnished this in- 
formation but have given some idea of the vast volume of literature 
on insects and how its contents are made available through the 
library. 
Many additions were made to the Bureau collection of photographs 
of entomologists. 
INSECT PEST SURVEY AND INFORMATION 
The Insect. Pest Survey added to the permanent files on the dis- 
tribution and abundance of insects 21,000 notes on domestic insects 
and 12,000 on foreign insects, bringing the total now available for 
consultation to 348.250. To the host-plant file there were added 50 
new genera and 100 new species, bringing the totals to 1.175 genera and 
2.700 species. 
The monthly Insect Pest Survey Bulletin was augmented by 
supplements on the alfalfa weevil (spread in 1939). chinch bugs 
(populations in hibernation, November-December 1939). the Euro- 
pean corn borer (status in 1939. colonization of parasites in 1939, 
estimates of damage in 1938 and 1939. and field stattis of its para- 
sites in the fall of 1938), grasshoppers (species and distribution in 
the 1938 outbreak), the hessian fly (survey at harvest time in 1939), 
the Japanese beetle (colonization of its parasites in 1938 and 1939), 
June beetle's (population and host preferences in southern Wisconsin 
in 1938), and mites (distribution and food-plant records of Para- 
tetvanychus cltri McG., P. ilids McG., P. pHosies C. and F., Tetrcmy- 
chus pacificm McG., and T. telarius L.). 
Ninety-one articles on entomological and quarantine subjects were 
released to the press and 73 radio talks were put on the air. Prepa- 
ration of film-strip material covered 3 new subjects. Two new 
motion pictures, both of which are sound pictures, were completed — 
one on the white-fringed beetle and one on termites. The Bureau 
participated in 31 exhibits, one of which was the above-mentioned 
general exhibit of the Bureau's activities held in the patio of the 
administration building of the Department of Agriculture, which 
attracted large numbers of visitors and of the Department's em- 
ployees and occasioned considerable press notice. 
Cooperative extension work in entomology was supervised both 
by this Bureau and by the Office of Cooperative Extension Work. 
Twelve numbers of the Bureau's Monthly News Letter, comprising 
422 pages, w r ere issued. 
Publications to the number of 472.000 copies were distributed,
