TRUCK-—CROP INSECTS 
J. E. Graf, in Charge 
The field laboratory at Richfield, Utah, for the study of the 
beet leafhopper, E. W. Davis, in charge, has been moved to Salt Lake 
City. This change was made in order to have the. laboratory more in 
the center of the area under survey, so that the ground could be cov— 
ered in much less time than it would be if the operations were centered 
in Richfield. The new quarters, at 601 McCormick Building, Salt Lake 
City, were occupied on November 5. 
K. L. Cockerham and 0. T. Dean, of Biloxi, W. B. Hollingsworth 
and M. H. Brunson, of Picayune, and F. A. Wright, of Bay St. Louis, all 
in Mississippi, attended the annual conference of the workers of the 
Mississippi State Plant Board, held at A. & M. College, on November 
25 and 26, to discuss the problems of the sweet—potato weevil. 
In the latter part of November C. B. Wisecup, of the field lab-— 
oratory at Sanford, Fla., in company with Dr. F. L. Wellman, of the Bu-— 
reau of Plant Industry, also stationed at Sanford, made an inspection 
trip in the Bradentown, Sarasota, and Everglade sections of southern 
Florida. This was done mainly to gather information as to damage by 
pests of vegetable crops. Injury by the tomato fruitworm and a mole 
cricket was found quite prevalent in the vicinity of Plant City, Pal- 
metto, and Sarasota. Rather unusual damage by a wireworm was observ-— 
ed in the vicinity of Palmetto on fruit of the pepper plants. Peppers 
which lay on the ground were fed upon by the wireworms, causing some 
S to 10 per cent injury to the crop. 
Appointments have been given to H. A. Mason, Agent, for duty at 
Columbus, Ohio, and to C. E. Woodworth, Associate Entomologist, for duty 
at Walla Walla, Wash. :
