212 BUREAU OF PLANT QUARANTINE [July-Sept. 
CAMPAIGN AGAINST PINK BOLLWORM STARTED IN COTTON FIELDS OF SOUTH 
(Press notice) 
September 25, 1933. 
The United States Department of Agriculture today concentrated its facili- 
ties for inspecting cotton-gin trash in the area around Enigma, Ga., where 
plant quarantine inspectors last week found pink hoi 1 worms during a routine 
inspection of gin trash. An intensive inspection of adjacent fields is also under 
way. Prompt extermination measures will he taken against any additional 
infestation discovered. 
This is the first time in 12 years that the pink hollworm has appeared in the 
main Cotton Belt of the United States, says Lee A. Strong, Chief of the Bureau 
of Plant Quarantine. Clean cultivation of the fields and sterilization of the 
seed are among the control measures advocated hy the Department. After 
the cotton is picked every bit of cotton plant and debris in an infested field 
must be pulled but, raked up, and burned. The seeds, in which the bollworm 
passes part of its life cycle, must be sterilized. In this way infestations have 
been stamped out over thousands of square miles in several cotton-growing 
States. 
Annual inspections of gin trash disclose any incipient infestation of pink 
bollworms, Mr. Strong says, and make it possible to take proper control meas- 
ures before the insect can build up a large population. A light infestation was 
discovered by such an examination last year in Florida, he adds, and, as a 
result of the control measures immediately taken, no infestation has been found 
there this year. 
ANNOUNCEMENTS RELATING TO THURBERIA-WEEVIL 
QUARANTINE (NO. 61) 
REVISION OF REGULATIONS 
Introductory Note 
The following revision of the Thurberia-weevil-quarantine regulations is 
issued to authorize the use of various improved treatments and other safe- 
guards that have been developed by the Department in recent years. The 
changes in every case provide for the issuance of permits for interstate ship- 
ments on conditions with which it will be simpler and less expensive to com- 
ply than those previously required, or under which a wider market for cotton 
products is authorized. 
Changes include provisions under which cottonseed given a special heat treat- 
ment of 145° F. for 1 hour is authorized shipment under permit to any destina- 
tion ; baled cotton lint may be either fumigated under vacuum, or compressed, 
or roller treated, instead of having to be both compressed and fumigated as 
heretofore ; and cottonseed hulls may be shipj^ed to nonregulated territory on 
the application of such special treatment as may be required by the inspector.
