Boll weevil activity during February.-- series of boll weevil 
hibernation cages were installed last fall at Florence, 8. C., Tallu]= 
lah, La., College Station, Tex.,'and Bufaula, Okla. At Florence 7/0 
cages with 500 weevils each, or 35,000 weevils, were placed in the 
cares with shelter material, and at Eufaula 56 cages, or 28,000 weevils, 
were installed. Daily observations throushout the- winter (eather 
permitting) were maie to determine the number..of weevils active in 
the cafes. At Florence, F. fF, Bony reports that no active weevils 

were recorded during February. This is tne ia February in which 
no active weevils were recorded since 1925 ar as due ve the unusu~ 
ally cold weather. »-A minimun: of 119. F., a, maximum of 69° I. andaies 
days with temperatures below freezing were recorded in February. 
No weevils were collected on field flight screens. At Tallulah, G. L. 
Snith reported 63 active weevils during February as compared with 50 
in February 1933, and 1;0/71 in February 19432. . From 9 flight screens 
3 weevils were collected, as compared with 1 weevil in February 1953 
from 20 screens and 168 weevils in February 1932 from man screens. 
The mininum temperature was 22° F. and the mean was 48. 9° F., which 
was 1.69 F. less than normal. At College Station, B. W. Dunnam ree 
ported some weevil activity for every day in the month, with a total 
of 380 active weevils noted, which-is about five times as many as for 
February 1933. The minimum temperature was 28° F., the maximum 7S F., 
and the mean 54.029 F, For Hepruery 1933 the minimum was 11° F,, the 
maxirmum 80° F., and the mean 48,73° F. There has been no freeze 
sufficient to kill all the cotton stalks in protected places and some . 
food has been available most of the time for active weevils. However, 
no weevils were ooserved feeding in February but some were observed 
in January, At Eufaula, H. C. Young reports that 104 active weevils 
were observed in February, but no activity has been observed since 
February Lé. pee SE 19 to 28 the highest daily mean tempera— 
ture has been 43,39 F, No active weevils were observed in the {0 
cages in February 1953. At Brownsville, Tex., the winter has been 
sO worm that old cotton stalks, remained. green and prodiced some fruit 
throughout the winter. Field collections of squares by T. C. Barber 
show that weevils have remained active and have been breeding contin-— 
uously. In 19343, 262 weevils emerged from collected squares in Decem— 
ber, in January ei 1,120 weevils, and in-February 1934 321 weevils — 
(incomplete data). ergence occurred onall but 7 days of the 3- 
months! period. rehei nf last years! cotton stalks were destroyed in 
February, but the newly planted fields were up to a stand by the end 
of théeenonth,. /This iesued ie early planting of the. new crop will 
leave only a very short gap in which no squares were available for 
breeding, and a continuous succession of green plants for feeding. 
Boll weevil control tests = aula, Okla., in 1933.—-H. C, Pome 
reporting on field tests for boll weevil control Peonaiceen last season, 
states that very small fains were iia tae from calcium arsenate dust— 
ing, owing to the light infestation. "Three tests were conducted on
