ANNOUNCEMENT RELATING TO PINK BOLLWORM QUARANTINE 
(NO. 52) 
B. E. P. Q. 493, Second Revision. Effective October 1, 1942. 
TITLE 7— AGRICULTURE 
Chapter III — Bureau of Entomology and Plant Quarantine 
Part 301 — Domestic Quarantine Notices 
pink bollworm quarantine regulations modified 
INTRODUCTORY NOTE 
The administrative instructions issued May 1, 1940 (Circular B. E. P. Q. 493, 
revised) modified the treatment requirements for the pink bollworm as to 
baled lint and linters and products thereof and restored certain requirements 
for handling cottonseed in certain counties in northwestern Texas and Lea and 
Roosevelt Counties, N. Mex. The present revision does not change the 
requirements for these counties. 
Continued improvement in seed sterilization and in sanitary measures in force 
at gins in the heavily infested area and at oil mills receiving and processing 
cottonseed produced in that area, makes it safe to allow linters produced from 
sterilized seed in such area to be moved interstate without additional treatment. 
The present revision of the administrative instructions therefore removes the 
requirement as to fumigation or roller treatment of linters produced from 
fcterilized seed originating in the heavily infested area. This modification of 
the quarantine regulation does not affect the procedure as to handling cottonseed 
originating in the heavily infested area as provided in paragraph (b) of 
regulation 4 (§ 301.52-4). 
§ 301.52-4b. Administrative in st ruct ions ; removing the treatment requirements 
as to cotton linters produced from sterilized cottonseed in the heavily infested 
areas, and extending the area in which oaled cotton lint may he moved from 
certain lightly infested anus in New Mexico and Texas without treatment. 
Pursuant to the authority conferred upon the Chief of the Bureau of Entomology 
and Plant Quarantine by the second proviso of § 301.52, Chapter III, Title 1. 
Code of Federal Regulations [Notice of Quarantine No. 52, on account of the 
pink bollworm], and having determined that facts exist as to the pest risk 
involved which make it safe to modify, by making less stringent, the restric- 
tions contained in paragraph (a) of § 301.52-1, notice is hereby given that, 
effective October 1, 1942, (a) all restrictions and certification requirements 
are hereby waived on the interstate movement from any regulated area of 
cotton linters produced from sterilized seed; and (b) all restrictions are hereby
