STORED-PRODUCT INSECT INVESTIGATIONS 
E. A. Back, in Charge 
In September George W. Ellington secured over 100,000 eggs of 
Sitotroga cerealella for shipment to the Barbados Department of Ag- 
riculture, for use in rearing Trichogramma parasites of Diatraea 
saccharalis. These eggs were taken to New York by Dr. R. T. Cotton, 
and placed on the S. S. Voltaire, which sailed September 15. On 
October 24 R. W. Tucker, Government Entomologist, notified Dr. 
Quaintance that about 75 per cent of the eggs had hatched success— 
fully. The eggs were laid between small strips of heavy paper, in 
accordance with the method used by Simmons and Ellington during their 
investigation of Sitotroga cerealella at Sligo, Md. 
S. E. McClendon, of the field laboratory at Thomasville, Ga., 
visited Louisiana early in October to investigate conditions with 
reference to the corn weevil on a number of large plantations in that 
state. 
Dr. R. T. Cotton spent October 13 in New York, with Dr. Nevil 
Hopkins, to observe improvements in the mechanism for treating cigars 
with superheated steam. 
Dr. R. C. Roark, of the Bureau of Chemistry and Soils, spent 
October 15 with Perez Simmons, at the field laboratory in Fresno, 
Calif., acquainting himself with methods for treating dried fruits 
for the control of insects. 
Dr. EB. A. Back returned October 26 from a visit to the field 
laboratories at Modesto and Fresno, Calif. On the return trip short 
stops were made at Houston, New Orleans, and Mobile, to inspect equip— 
ment for the treatment of flour intended for export. 
The Cappell Upholstering Company, of Dayton, Ohio, through 
the National Association of Upholstered Furniture Manufacturers, 
wrote this office on October 29 requesting 1,000 reprints of the 
paper entitled "Tobacco Beetle as a Pest of Furniture." During the 
past three years the tobacco beetle has been sent to the Bureau of 
Entomology, as a pest of overstuffed furniture, from nearly every 
state in the Union. 
During the months of September and October Messrs. Larson and 
Fisher, of the bean weevil field laboratory at Alhambra, Calif., 
have been overloaded with samples of beans taken from warehouse re— 
ceipts in Merced and Stanislaus Counties. Warehousemen take no action 
until a reporton the status of the samples as regards the bean weevil 
has been made by the laboratory. The Bureau is receiving excellent 
cooperation from persons growing and warehousing beans in this region.
