CHANGES IN REGULATIONS 
During the fiscal year 1935 two changes were made in the pink bollworm 
quarantine regulations, both of which were for the purpose of including the 
newly infested sections. 
Amendment no. 1, effective September 19, 1934, was made for the purpose 
of adding Jackson and Suwannee Counties, Fla., to the regulated area. 
Amendment no. 2, effective October 31, 1934, was made for the purpose of 
adding Dixie, Hamilton. Lafayette, Levy, and Taylor Counties, Fla., and 
Andrews and Ecfor Counties, and part of Midland County, Tex., to the 
regulated area. 
The above areas were designated as lightly infested. At present the regu- 
lated areas include 3 counties in southern Arizona, 14 in north-central Florida, 
parts of 3 in southern Georgia, 9 in southern New Mexico, and 17 entire 
counties and parts of 4 additional ones in western Texas. Of this area five 
counties and part of another in Texas are designated as heavily infested and 
all of the remaining area as lightly infested. 
CONTROL AND ERADICATION MEASURES 
No changes were made this past season in the measures enforced to control 
and prevent the spread of the pink bollworm from infested areas. These 
consisted of (1) disposal of gin trash, (2) sterilization of seed, (3) supervision 
of oil mills, (4) fumigation, compression, steaming, and roller treating of lint, 
(5 1 ! road stations, and (6) cooperation with Mexico. 
DISPOSAL OF GIN TRASII 
Most gins are equipped with cleaning machinery through which the cotton 
passes before entering the gin stands. A considerable amount of trash is taken 
from the cotton by this machinery and many pink bollworms arc discharged 
with the trash, the number depending, of course, on the degree of infestation. 
The regulations require the daily disposal of this trash by burning, steriliza- 
tion, or grinding. Several years ago the Texas and New Mexico regulations 
were amended to require the daily disposal of trash to December 1 of each 
year, the average killing frost date being prior to this. The dinners have 
always cooperated by continuing daily disposal of trash until a killing frost 
occurs, if it is later than December 1.
