TRUCK-CROP INSECT INVESTIGATIONS 
J. E. Graf, Entomologist Acting in Charge 
Dr. F. H. Chittenden, who has been in charge of Truck-Crop Insect 
Investigations, will devote his time in the future to special studies of 
truck-crop insects and to taxonomic work. 
J. E. Graf, lately in charge of field work pertaining particularly to 
the sweet-potato weevil in Florida and the Mexican bean beetle, with head- 
quarters at Birmingham, Ala., has been transferred to the central office 
at Washington, D. C., as acting head of Truck-Cyrop Insect Investigations, 
C. H. Popenoe, entomologist in Truck-Crop Insect Investigations, has 
been authorized to devote his entire time to fundamental research work in insttt 
behavior and chemical control, and will establish headquarters at the laboratory 
at Sligo, Md., where investigations of fruit insects and truck-crop insects 
are being conducted. 
; W. H. White has just returned from Seaford and other points in Delaware, 
yvhere, in company with C. C. Woodbury of the National Canners Association, 
he made general observations tending toward a better knowledge of the practical 
control of the pea aphis on cannery peas with nicotine dusts, applied by 
high-power apparatus. 
J. E. Dudley, Jr., in charge of the investigation of the pea aphis in 
its attacks on cannery peas, has been authorized to assume temporary head- 
- guarters at Columbus, Wise, where he will undertake cooperative control 
5 experiments and studies throughout the pea-growing season, in cooperation 
with State entomologists and the Columbus Canning Co. 

% R. E. Campbell reports successful results in the control of the pea 
aphis on cannery peas in southern California, as the result of extensive 
experiments undertaken in the vicinity of San Jose. The experiments indicate 
that sufficiently inexpensive control measures will be worked out in the 
near future.
