On September 5 C. K. Fisher, of the bean-—weevil field laboratory 
at Modesto, Calif., began the annual check on the infestation of the 
bean crop as delivered in the warehouses in California. The hearty 
cooperation of warehousemen and State and County agents is being ex-— 
tended to Mr. Fisher, as in the past. The percentage of infestation 
for 1930 promises to be very low as compared with that of previous years. 
During September S. E. McClendon investigated conditions regard— 
ing the corn weevil in Louisiana. 
A. Q. Larson reports that examinations made in one 40-acre field 
in Oregon, planted for the third consecutive year in field peas, showed 
that 913 per cent of all peas produced were weevily. He estimates that 
in this field 47,000,000 adult weevils were left behind in the stubble 
after harvest. While this is an extreme case of infestation, it is 
sufficient to indicate the interest of northwestern farmers in the in- 
vestigations on the pea weevil, of which Mr. Larson assumed charge July 1. 
William G. Hamilton resigned as Field Agent on September 3. 
TROPICAL, SUBTROPICAL AND ORNAMENTAL PLANT INSECTS 
A. C. Baker, in Charge 
C. P. Clausen, who has been in the Malay Peninsula and Dutch East 
Indies since the spring of 1929, collecting parasites of the citrus 
black fly, arrived in the United States September 17, with several cases 
of material. He spent September 18 and 19 in Washington, conferring with 
Bureau officials in regard to this work. 
P. A. Berry came to Washington on September 24 for conference in 
regard to the parasite work in Cuba. He returned to Cuba on September 
e6, taking with him some of the parasite material brought by Mr. Clausen. 
Dr. Emily W. Emmart has been appointed Assistant Entomologist, 
and assigned to study the morphology and histology of the Mexican True 
fly as it develops under different environmental conditions. Her head— 
quarters will be at Mexico City,-:where:she reported for duty September 
ee. Dr. Emmart recently received her doctor's degree from Johns Hopkins 
University. 
In September the resignations of Sheppard A. Watson, Paul M. 
Scheffer, Arthur J. Haas, Theodore R. Hansberry, Clayton H. Huff, R. P. 
Buckner, John M. McEwen, and Lorin C. Fife, Field Assistants, became 
effective.
