GENERAL Cooperative Report on Boll ""eevil Bneirgerice from Cage Tests Prior 
STATEMENT to April 1. (U. S. Bureau of Entomology, Delta Laboratory, Tallula* 
La. ) . 
At a recent meeting of the State and Federal entomologists engaged 
in experimental work on the cotton boll weevil, a cooperative sys- 
tem "as devised for the purpose of compiling and disseminating in- 
formation on boll-weevil survival in hibernation. It vras found 
that hibernation cage tests had been installed at eight different 
points ranging from Texas to North Carolina last fall and it "as 
agreed by the investigator in charge of each of these series of 
experiments to report the emergence results on the 1st end. 15th 
of each month during the emergence period to the Tallulah Labor- 
atory of the U. S. Bureau of Entomology. At that point, the 
figures are compiled and analysed with a vie^ of determining as 
nearly as possible probable -eevil infestation at the different 
points represented. The locations of these cooperative stations 
are as follows: 
Eaton Rouge, La. - Louisiana State Experiment Station, 
Dr. "*. E. Hinds cooperating. 
Tallulah, La. - U. S. Bureau of En to mo log:/,. 
Delta Lab orator:'-. 
Florence, S. C. - Joint Station, South Carolina State Experi- 
ment Station and U. 3. Bureau of Entomology, 
Dr. F. A. Fenton cooperating. 
Clemson College, S. C. - South Carolina State Experiment 
Station, 
Professor E. TT. Barre cooperating. 
Aberdeen, IT. C. - North Carolina State Experiment Station, 
Professor Franklin Sherman cooperating. 
Rocky Mount, N. C. - North Carolina State Experiment Station, 
Professor Franklin Sherman cooperating. 
College Station, Tex. - Texas State Experiment Station, 
Dr. F. L, Thomas cooperating. 
Holly S-orings, Miss. - Mississippi State Experiment Station, 
I£r. C. T. ~Hm.es cooperating. 
The records which have been received at the Delta Laboratory to 
date include observations up to the first of April and thus are of 
course of a decidedly preliminary nature and do not warrant as 
general conclusions as can be dra"n from the later records. The 
most significant feature so far is the exceedingly high emergence 
at Florence, S, C. It happens that the same series of cages ^ere 
installed at that point both last pear and t V' s year e^A it is es- 
pecially interesting to compare the results. On the first of 
- ril, 1924, only S weevils had emerged from the entire series of 
cages whereas on the first of April, 1925, 343 weevils had emerged, 
or 53 times as many as in the preceding year. This verifies 
other observations to the general eixect that a heavy initial emer- 
gence of weevils may bo expected in the Southeastern States.
