approxiraately 1 per cent whereas last year the survival ran from 4 to above 
13 per cent. The spring and early summer continued favorable for the weevil 
and the early=crop cotton was very seriously damaged during July. The reduction 
of some 25 per cjnt. reported in. the .August 1 crop report was ascribed very 
largely to this heavy- weevil population and the reduced use of insecticides due 
to the financial situation. Hot, dry weather during' August very materially 
relieA^ed the situation by killing -.a' large proportion of the weevils in the 
squares. In western Texas and western Oklahoma weevil populations were extreme- 
ly low and weather conditions favorable for cotton* 
PINK BOLL WORM .■■---..... 
Inspection of gin trash during the late summer and fall, using the gin- 
trash machine, indicated that the infestation of the pink boll worm 
(Fectinophora gossypiella Sound.) in the Big Bend district of Texas was the 
heaviest in the history of the infestation in that area. ■ This was further 
complicated by two severe floods which washed away a large amount of possibly 
infested material. Inspection of flood debris has indicated that large numbers 
of worms 'are in this material. During June the insect was discovered in wild 
cotton in southern Florida. A survey disclosed that this infestation extended 
from Loke Worth in Palm Beach County southward to the Florida Keys and well out 
on these keys, thence half way up the west coast to Manat«o Gounty. This, 
territory, however, is not within the commercial cotton-growing areas and was 
widely separated from the eastern Cotton Belt. Late in the fall a light 
infestation was found at three points in northern Florida in Alachua and 
Columbia Counties, the first time that this insect has been recorded in the 
eastern Cotton Belt. '■ . 
SUGARCANE BORER ..,-.. 
The sugarcane borer ( Diatraea saccharalis Fab.)- remained active throughout 
the winter of 1931-32. The cold weather of March materially checked the insect, 
however, by killing a large part of the sugarcane tops in Louisiana, and in 
consequence much less damage than usaal was done this year. Large numbers of 
two South American parasites of this insect, Paratheresia clarinalpis V. di? W. 
and Ipobracon rimac Wolcott, were liberated in the Gulf region during the year. 
A late fall survey of the area in Louisiana devoted to sugarcane showed that 
sugarcane borer damage ranged on the whole from 5 to 100 per cent of the stalks 
infested. Toward the northern limits of the infested area the infestation 
went as low as 2 per cent. The joint infestation was not excessive, even in 
fields where all the stalks were infested. 
BROWN SUGARCANE ROOT WEEVIL 
The brown sugarcane root weevil ( Anacentrinus subnudus Buchanan) was 
described this year. 1 An insect now identified as this species was first 
observed in 1910 at Berwick,- La. It was collected in 1912 on sugarcane stubble 
at New Orleans, and again in 1919. In 1925 it was found damaging sugarcane by 
boring into the woody part of the plant. Similar damage was observed in 1929 
and 1930 in'Louisiana. In 1931 a first-year's stubble field near Arnaudville, 
•La., was almost totally ruined by this insect. In the spring of this year a 
large number of buds were kiLled by this weevil, but in general it was not, so 
abundant as it was last year.- - .■'
