NOTICE OF QUARANTINE NO. 64 (REVISED) 
I Approved October 15, 1937; efieoctive October 15, 1937] 
I, Henry A. Wallace, Secretary of Agriculture, have determined that it is neces- 
sary to Quarantine the State of Texas to prevent the spread of an injurious insect 
known as the Mexican fruitfly {Anastrepha ludens Loew), new to and not here- 
tofore widely prevalent or distributed within and throughout the United States. 
Now, therefore, under authority conferred by the Plant Quarantine Act of 
August 20, 1912 (37 Stat. 315), as amended by the act of Congress approved March 
4, 1917 (39 Stat. 1134, 1165), and having duly given the public hearing required 
thereby, I do quarantine the said State of Texas, effective on and after October 
15, 1937, and by this Notice of Quarantine No. 64 do order that no fruits of any 
variety shall be shipped, offered for shipment to a common carrier, received for 
transportation, or carried by a common carrier, or carried, transported, moved, 
or allowed to be moved interstate from the said quarantined State in manner or 
method or under conditions other than those prescribed in the rules and regula- 
tions promulgated pursuant thereto or under such modification thereof as may 
be issued by the Chief of the Bureau of Entomology and Plant Quarantine as 
hereinafter provided : Provided, That the restrictions of this quarantine and of 
the rules and regulations supplemental thereto or modification thereof as herein- 
after provided, may be limited to the areas in the State of Texas now, or which 
may hereafter be, designated by the Secretary of Agriculture as regulated areas: 
Prodded further. That such limitation of the restrictions to the regulated areas 
shall be conditioned upon the said State providing for and enforcing such control 
measures with respect to such regulated areas, including the control of intrastate 
movement of host fruits from such areas, as in the judgment of the Secretary of 
Agriculture shall be deemed adequate to prevent the spread of the Mexican fruit- 
fly therefrom to other parts of the State : And provided further. That, except as to 
extension or reduction of the regulated area, the Chief of the Bureau of Ento- 
mology and Plant Quarantine may modify by administrative instructions any 
of the restrictions of the regulations supplemental hereto when in his judgment 
such action is necessary to prevent the spread of the Mexican fruitfly. 
Done at the city of Washington this 15th day of October 1937.
