ANNOUNCEMENTS RELATING TO MEXICAN FRUITFLY QUARANTINE 
(NO. 64) 
LOW-TEMPERATURE TREATMENT AUTHORIZED FOR MEXICAN FRUITFLY IN 
TEXAS COUNTIES 
[Press notice] 
September 26, 1941. 
The Mexican frnitfly Federal quarantine on grapefruit and oranges in the 
regulated area in Texas has been modified to allow treatment by a low-tempera- 
ture process as a condition of certification for shipment out of the area, the 
United States Department of Agriculture said today. The area includes the 
counties of Brooks, Cameron, Dimmit, Hidalgo, LaSalle, Webb, Willacy, and 
portions of Jim Wells County. 
Owing to the wide acceptance by the citrus-fruit industry in Texas of the 
vapor-heat method of treatment for the fruitfly there is little occasion for 
the use of the low-temperature method. 
For those who desire to employ that treatment, however, the administrative 
instructions just issued by the chief of the Bureau of Entomology and Plant 
Quarantine provide for cooling the fruit until the approximate center reaches 
33° F. and holding it at or below that temperature for 18 days, or cooling it 
to 34° for 20 days, or to 35° for 22 da vs. 
The vapor-heat treatment method, authorization for which is continued in the 
current instructions issued as Circular B. E. P. Q. 472 revised, effective Sep- 
tember 25, provides for heating the fruit for 14 hours, during which time the 
temperature shall be raised to 110° F. and maintained at or above that tempera- 
ture for the last 6 hours of such treatment. 
B. E. P. Q. 472 revised, 
Superseding P. Q. C. A.'s 329 and 330. Effective September 25, 1941
