NOTICE OF QUARANTINE NO. 64 
(Effective on and after August 15, 1927) 
I, William M. Jardine, 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 fruit worm (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 
August 15, 1927, 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: Provided, That the restrictions of this 
quarantine and of the rules and regulations supplemental thereto 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 when in the judgment of the Secre- 
tary of Agriculture the enforcement of the aforesaid rules and regulations as to 
such regulated areas shall be deemed adequate to prevent the spread of the Mexi- 
can fruit worm: 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 as in the 
judgment of the Secretary of Agriculture shall be deemed adequate to prevent 
the spread of the Mexican fruit worm therefrom to other parts of the State. 
Done at the city of Washington, this 10th day of August, 1927. 
Witness my hand and the seal of the United States Department of Agriculture.

Secretary of Agriculture.
