_ B. L. Boyden, in charge of the Tampa, Fla., laboratory, visited 
sanford, Fla., to start spraying operations against the celery leaf-—tyer, 
in cooperation with the Florida State Plant Board and Experiment Station, 
K. L. Cockerham, J. A. McLemore, li. M. Mingee, Troy Thompson, and 
F. A. Wright, all connected with the work of eradicating the sweet— 
potato weevil in Ifississippi, attended the annual meeting of the Mississippi 
State Plant Board, held in the latter part of December at Mississippi 
A. & M. College. A considerable portion of the time was given to discussion 
of work relative to the eradication of the sweet-potato weevil. 
F. P. Amsler, a former employee of the Mississippi State Plant Board, 
has been given a temporary appointment as Field Assistant, and is now 
stationed at. Grand Bay, Ala., assisting S. C. Brummitt in clean-up work, 
and in scouting for the sweet-potato weevil in MobileCounty. Later, Iir. 
Amsler will probably devote several weeks to work in Hancock County, Hiss. 
K. L. Cockerham, Biloxi, Miss., reports that several cold snaps which 
recently occurred in southern Mississippi will in all probability result in 
a general destruction of exposed vegetation and small potatoes left in 
the sweet—potato fields. As a result, judging from several years of 
observation, Mr. Cockerham believes that losses from the sweet-potato 
weevil will be light in 1926. It appears that the weevils suffer more from 
the destruction of over-wintering food than they do from the direct effect 
of the temperature upon themselves. ; 
Je Op Elmore, of, the Alhambra, Calif., laboratory, recently visited 
the Imperial Valley section of California, finding there damage to lettuce : 
from cutworms and the alfalfa looper.
