Six days were spent by Mr. McGregor in a study of the problems 
relating to citrus pests in Arizona. This work was done in response 
to a special request from the field department of the California Fruit 
Growers Exchange. Contacts were made with several leaders in the citrus 
industry in Arizona, and a modest start was made toward control of the 
citrus pests.

COTTON INSECTS 
B. R. Coad, in Charge 
Professor Filippo Silvestri, head of the Agricultural Institute of 
Portici, Italy, spent August 28 at Tallulah, where he was shown through 
the various departments of the field laboratory. He was especially in- 
terested in the dusting of cotton by airplanes, and was enthusiastic in 
his praise of the laboratory's scientific equipment and the extent of its 
Operations. His visit to the South was intended particularly to study 
at first hand the cane borer and the boll weevil. Before sailing for 
italy, at the end of September, Professor Silvestri will visit Columbus, 
Ohio, the Experiment Stations of New Jersey and Massachusetts, and the 
Department of Agriculture, at Washington, D. C. 
C; H. Billett, photographer, left Tallulah in August for an 6x-= 
tended trip in the West, taking with him a complete photographic field 
equipment. He will visit the field laboratories at El Paso and Presidio, 
Tex., Tucson, Ariz., Calexico, Calif., and elsewhere, to make photographs 
of the various phases of the investigations of the pink bollworm, Thur- 
beria weevil, and cotton leaf perforator. 
A. J. Chapman left Tallulah in the latter part of August for a 
new assignment at Presidio, Tex., where he will devote his time to in- 
vestigations of the cultural methods of controlling the pink bollworm. 
Mr. Coad has gone on an extended western trip, to last probably 
two months, during which he will visit the field laboratories dealing 
with cotton insects occurring in western Texas, Mexico, Arizona, and 
California. 
H. C. Young has completed his season's work on the boll weevil 
in Oklahoma, and has gone to El Paso, Tex., to take up his winter project 
on the pink bollworm and the Thurberia weevil. 
In August F. J. Potter, Glen Willingham, John H. Russell, William 
C. O'Dowd, John M. Landrum, and Lester E, Turberville were appointed Field 
Assistants. 
In the month of August the resignations of Harlow B. Mills, James 
Watkins, Phil H. Berry and F. J. Potter, Field Assistants, became effec-— 
tive.
