COTTON INSECTS 
Changes in field Laboratories. --The field laboratory at Eufaula, Okla., 
where experiments in boll weevil control under Oklahoma conditions have been 
_ conducted under the direction of H. C. Young, in cooperation with the Oklahoma 
Experiment Station and Extension Service, has been discontinued. Considerable 
data on the abundance and damage caused by the weevil inthe State and control 
measures suitable for local conditions were obtained and will be published in 
the near future by the experiment station. On June 1 Mr. Young was transferred 
to State College, Miss., where he will work in cooperation with the Mississippi . 
Experiment Station on cotton insect problems. 
EH, W. Dunnam, in charge of the cooperative bollworm investigations at 
College Stetion, Tex., was transferred in June to Stoneville, Miss., to take 
charge of a new project for studying the factors influencing weevil resistance 
in cotton, His new assignment will be to work in cooperation with the cotton 
breeders of the Department, the Mississippi Experiment Station, and others in 
an effort to develop cotton varieties more resistant to weevil damage. 
The laboratory at Brownsville, Tex., has been closed for the summer and 
T. C. Barber transferred to Buckeye, Ariz., to study the hemipterous insects 
of cotton in that section, 
F, A. Fenton, who has been in charge of the pink bollworm laboratory at 
Presidio, Tex., has resigned, effective July 1, to accept a position as head 
of the Department of Entomology of the Oklahoma A. &M. College and Experiment 
Station. A. J. Chapman, of the Presidio staff, will be temporarily in charge 
of the laboratory. 
C. F. Rainwater has been transferred from Talluleh, La., to Florence, §.C., 
to study the cotton. root aphid and thrips. This new project will be under the 
direction of F, F. Bondy ond in cooperation with the South Carolina Experiment 
Station. 
Cotton leaf worms appear early.--R. L. McGarr collected two half~grown leaf 
worms (Alabama argillacea Hbn.) on cotton in the vicinity of Port Lavaca on 
May 24, Additional specimens were found onMay 26 near Gregory and Robstown, 
Tex. Adults emerged during the first week of June. This is the earliest record 
of leaf worm appearance in the United States since 1926, when they were found at 
Wharton, Tex., on May 18. No reports of their appearance in other sections have 
been received this season. 
Boll weevil activity.--Reports from field laboratories and correspondents 
indicate that boll weevils are very abundant this season in all infested sections, 
except along the Atlantic seaboard, At Florence, 5.C., the severe cold of last 
winter caused a heavy mortality among hibernating adults and weevils are about 
half as abundant in the fields as they were at this time last year. At Tallul’ 
La., R. C. Gaines and assistants, in their field examinations during the last 
week in May, found 303 weevils per acre, as compared with 126 in 1933 and 188 in 
1932. Clay Lyle, Entomologist of Mississippi, reports an average of 145 weevils 
per acre on the infested farms and 75 per acre for all farms visited in Mississip- 
pi during the week ending June 4, This compares with an average of 118 per acre 
for the infested farms and 60 per acre for all visited on the same date last year. 
H. C. Young reports an. average of 212 weevils per acre on 5 fields examined in
