STORED~PRODUCT INSECT INVESTIGATIONS 
E. A. Back, Senior Entomologist, in Charge 
A. 0. Larson and C. K. Fisher were located during October and 
the early part of November at Modesto, Calif., where, in cooperation 
with warehouse operators and the county horticultural commissioners, 
they examined nearly 2,000 samples of beans. It was found that from 5 
to 85 per cent of the samples from the various storage houses were in— 
fested with bean weevils. An average of 359.8 per cent of all the sana 
from 17 warehouses showed infestation in some degree. 
Perez Simmons, in charge cf the dried—fruit insect investigations 
at Fresio, has submitted tabulaticns of the results of the examinations 
of approximately 40,000 figs made at his laboratory by B. J. Howard, of 
the Bureau of Chemistry and Soils, and by the entomological workers. 
The five classes, insect-infested, moldy, sour, bird-pecked and dirty, 
and worthless, are considered to be of descending importance in the order 
named.. The Fresno Sunday Republican for October 30 states that these 
examinations and orchard-run fruit indicated that about 46 per cent of 
the figs were totally bad, and 54 per cent merchantable. This statement 
is food for thought, and indicates the seriousness of the problems of 
fig infestation. 
Dr. R. T. Cotton left Washington October 13 and spent about a 
week with S. E. McClendon in southern Georgi , where comparative tests 
were conducted in corn cribs with the ethylene dichloride—carbon tetra— 
Chloride mixture, carbon disulphide, carbon tetrachloride, and chloro— 
picrin. 
Word was received on November 26 that the Executive Committee 
of the Dried Fruit Association of California has donated an additional 
$1,000 to aid in rinancing the work of the dried—fruit insect investiga— 
tions at Fresno. 
Jee Oo Hamlin arrived in Washington November 27 for conference, 
and to arrange for a furlough during the winter months. Mr. Hamlin will 
complete his doctorate work at the University of Ohio. 
During November Secretary Jardine received a considerable number 
of letters from various persons and organizations commending the work of 
A. 0. Latson and C. K. Fisher, and requesting that they be located at 
Modesto in order that they might be more continuously available in as— 
Sisting in the campaign against bean weevils. Among those writing Sec— 
retary Jardine were the Horticultural Commission of Stanislaus County, 
the Board of Supervisors of Stanislaus County, the Modesto Chamber of 
Commerce, the Turlock Chamber of Commerce, the Stanislaus County Develop— 
ment Board, the Modesto Junior Aggies, and the Stanislaus County Agent. 
Secretary Jardine and Dr. Marlatt have approved plans for the moving of 
the bean weevil laboratory from Alhambra to Modesto.
