STORED-PRODICT INSECT INVESTIGATIONS 
E. A. Back, Entomologist, in Charge 
' Special attention is called to a typewritten translation made by Mrs. 
Perez Simmons of the work on the Angoumois grain moth by Duhamel and Tillet 
and entitled "History of an Insect Which Devours the Grains of Angoumois." 
This rather extensive translation has been neatly bound with photographic 
copies of original illustrations, together with certain other illustrations 
of interest to the present-day reader. As the editor, Mr. Simmons, writes: 
"The interest which lies in this treatise (published in 1762) on the Agoumois 
grain moth is due both to the fact that it is the principal original contri- 
bution to our knowledge of the biology of the species and because itis a 
Pioneer among monographs dealing with injurious insects. . . Duhamel du 
Monceau had unusual ability as an investigatcr, in the organization of coop- 
eration, and as an artist and painstaking writer. His suggestions for the 
application of quarantine measures to prevent the spread of the insect, and 
for the use of police power in enforcing clean-up work, sound decidedly mod- 
ern." Several less extensive translations, particularly from the Russian 
and dealing with grain pests, have been made and deposited in the Bureau 
Library. All translations of this sort should trove very useful in investi- 
gational work. ' 7 ; 
J. C. Hamlin, in charge of the field work in dried-fruit insect in- 
vestigations, was recently interviewed by P. M. Williams and BE. J. Murphy, 
of the Bureau of Agricultural Economics, concerning the influence of insect 
er geese on the local application of the Warehouse Act to stored dried 
ruits. 
In September, 1925, Dr. Back, with S. E. McClendon, reviewed the re- 
sults of experiments in and about Brunswick, Ga., for the control of the corn 
weevil. The scarcity of rice weevils in ripe corn grown on isolated farms — 
where fumigation of cribs had been undertaken by the Bureau was very gratify- 
ing. On certain other farms, where no fumigations had been made, from 60 to 
90 per cent of the ears of corn were found to contain weevils previous to har- 
vesting, and some. of the less protected ears were already practically destroyed. 
in September. A. QO. Larson prepared and mounted an educational exhibit 
at the Stanislaus County, Calif., Fair. . This display, consisting of enlarged 
photographs and other material illustrating the biology of bean weevils and 
the destruction they cause, attracted much attention and received favorable 
newspaper comment. The fact that bean weevils have made bean growing unprof- 
itable in some sections of California, and apparently are everywhere on the 
increase where remedial measures have not been attempted, has driven home to 
bean growers the practical value of the Bureau's work on these pests. 
At the request of the Ordnance Department of the Army,.Dr. Cotton on 
October 2 supervised the fumigation of 450,000 cubic feet of space at the 
Reserve Supply Depot at New Cumberland, Pe. Clothes moths destroying the 
felts of thousands of crated steel army helmets were the object of attack.
