COTTON-INSECT INVESTIGATIONS 
B. R. Coad, Entomologist, in Charge 
B. R. Coad and R. C. Gaines have spent the greater part of Feb- 
ruary and March in western Texas, New Mexico, and Arizona, perfecting 
plans for the season's investigations of the Arizona weevil and the pink 
bollworm. Final arrangements have been made for the inauguration of a 
complete program of research on the pink bollworm, which has now become 
sufficiently abundant in some of the more remote sections of western Texas 
to permit research investigations there.. The investigations of the 
Bureau and the state Experiment Station of Texas will be carried on co- 
operatively; the funds of the two organizations are pooled, and the entire 
research program is to be conducted under the active direction of Dr. 
F. A. Fenton, of this Bureau, with headquarters at El Paso, Tex. A lab-— 
oratory has been installed at Presidio, and additional substations at 
Castolon and Marfa, all in Texas, and the new organization, involving 
at least half a dozen entomologists, will inaugurate a complete biological 
and ecological study of the insect in this region. During the current 
season especial attention will be devoted to the manner of spread, with 
particular reference to the questions of flight and wind transportation. 
M. T. Young, F. F. Bondy and W. A. Stevenson, who have been tem- 
porarily detailed to weevil investigations in Arizona during the winter 
months, have returned to their headquarters at Tallulah. 
E. W. Dunnam, who for a number of years has been stationed at 
Florence, S. C., conducting biological investigations on the boll weevil, 
has been transferred to Tallulah, La., where he plans to continue the 
same line of work. He will give special attention to the seasonal habits, 
dispersal and chemotropic reactions of the weevil. 
V. V. Williams, who for several years has been stationed at Cal- 
exico, Calif., investigating the biology of the cotton-leaf perforator, 
has spent the month of March in Tallulah, completing the manuscript of a 
progress report on this problem. 
On March 30, at Memphis, Tenn., B. R. Coad attended a meeting of 
commissioners of agriculture, State quarantine officers and State en- 
tomologists of the Southern States, called to consider the problem of 
the pink bollworm in Texas. The sentiment of the meeting was unani- 
mously in favor of the inauguration, at the earliest practicable time, 
of a plan for complete eradication of the pink bollworm from the North 
American continent.
