SEC. 301.64— NOTICE OF QUARANTINE NO. 64 (REVISED) 
[Approved October 14, 1937 ; effective October 15, 1937] 
I, Henry A. Wallace, Secretary of Agriculture, have determined that it is 
necessary 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 
heretofore 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 here- 
inafter provided: Protnded, That the restrictions of this quarantine and of the 
rules and regulations supplemental thereto or modification thereof as hereinafter 
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: 
Provided 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 fruitfly 
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. 1 
Done at the city of Washington this 14th day of October 1937.
