‘It will be noted that with the exception of 1931 and 1932 365 
live weevils per ton of moss at Tallulah is the highest number in 
any year for which records are available. For southern Louisiana, 
{il live weevils per ton is greater than in any year except L9H 
and 1931. For South Carolina, this year's record of 78 weevils per 
ton is less than that of 1927 to 1932, inclusive. For Georgia, the 
es weevils per ton is the lowest number ever recorded, For Alabana, 
the 9/ weevils per ton this year is less than for any previous year 
except 1928. 
Soil—~animal investigations and relationship of insects to cotton 
diseases.--L. Dean Christensen, temporarily employed from August 7 
to December 6 at the Bryan, Tex., Laboratory, working in cooperation 
with J. J. Taubenhaus, of the Division of Plant Pathology and Physio- 
logy, Texas Agricultural Experiment Station, has reported on the 
season's work, Feeding by insects upon the roots of cotton was again 
found to be light under normal conditions in the areas examined in 
Texas. In well-cultivated cotton fields a maximum of 4,846 white 
grubs per acre were encountered; in poorly cultivated ficlds, rich in 
erasses, an average of 13,/30 per acre, and in cornfields an average 
of 30,460 per acre were found, Wireworms were occasionally found 
but never in concentration. Six other species of soil-inhabiting and 
surfacc-roving beetles were found. This year's population studies of 
the smaller soil animals have been confined to late summer estimates 
of cotton fields on Houston clay near Temple, Tex. Average results 
by soil depths were as follows:

Experiments were conducted with some of the more common cotton 
field insects to determine the possibility of their spreading Fusarium 
wilt of cotton by ingesting the fungus with their food and depositing 
st in a viable form with the feces and also by spores adhering to the
