REPORT OF THE CHIEF OF THE BUREAU OF ENTOMOL- 
OGY AND PLANT QUARANTINE, AGRICULTURAL RE- 
SEARCH ADMINISTRATION, 1944 
United States Department of Agriculture, 
Washington, D. C, September 16, 1944. 
Dr. E. C. Auciiter, 
Agricultural Research Administrator. 
Dear Dr. Auchter : I submit herewith a report of the work of the 
Bureau of Entomology and Plant Quarantine for the fiscal year ended 
June 30, 1944. 
Sincerely yours, 
P. N. Annand, Chief. 
Research which has for its objective more stable agricultural 
production was never more needed than it is today. A great 
part of the efforts of all the farmers on all available land can be 
frustrated by outbreaks of insect pests if they occur at critical times 
and places. No plans for victory in the war or for subsequent recon- 
version in this country and reconstruction abroad can be successful if 
they do not take into account the possibility of epidemics of insect- 
borne diseases and large-scale losses in yield or quality of growing 
crops or stored products resulting from the attacks of destructive in- 
sects. Research in the Bureau of Entomology and Plant Quarantine 
seeks to learn more about injurious insects — how to recognize them, 
their habits, and measures to control them at reasonable cost — and 
also how to make better use of beneficial insects. 
Some of the information thus acquired is utilized directly in the 
Bureau's programs to suppress dangerous insects and to prevent their 
spread. Most of the results of research are made available as rapidly 
as possible. Many important contributions have been made, some of 
which are being employed to protect the health and comfort of civil 
and military populations and some to assist in stabilizing agricultural 
production by reducing losses and maintaining more consistent yields. 
Measures for louse control developed by the Bureau and recom- 
mended to the Army and Navy were used to good purpose in stamping 
out a typhus epidemic in Naples, Italy, last winter, as recorded in 
accounts carried in periodicals of national circulation. As a result 
of this experience a high official in the War Department has stated 
that typhus fever has now become one of the easiest diseases of man 
to control. 
Striking reductions in infestations by the Japanese beetle are follow- 
ing the continued distribution of the milky disease of the grubs. At 
the request of the War Department the distribution during the past
