ANNOUNCEMENTS RELATING TO MEDITERRANEAN FRUITFLY AND 
MELONFLY QUARANTINE (NO. 13) 
HAWAIIAN FRUITS AND VEGETABLES TO BE ADMITTED TO MAINLAND AFTER 
STERILIZATION 
[Press notice] 
October 20, 1938. 
Modification of the fruitfly regulations affecting the movement of products 
from Hawaii to the mainland, effective November 1, was announced by Lee 
A. Strong, Chief, Bureau of Entomology and Plant Quarantine, today. 
Experimental work carried on at field stations of rhe Bureau, Dr. Strong 
said, has developed the fact that exposure to heat or to cold under controlled 
conditions for a specified time will destroy immature stages of the Mediterranean 
fruitfly or the melonfly that may be present. 
On the basis of this evidence provision will be made, effective November 1, 
1938, for the shipment to the mainland of Hawaiian fruits and vegetables 
treated in that territory under the supervision of an inspector of the Depart- 
ment of Agriculture by either of two treatments. 
The cold or low-temperature treatment involves chilling fruits or vegetables 
until they reach a temperature of 35° F. at the center and maintaining this 
for 15 days. The hot or high-temperature treatment consists of heating the 
product to 110° at the center and holding it for 8 hours.

ADMINISTRATIVE INSTRUCTIONS— THE SHIPMENT OF FRUITS AND VEGETABLES 
FROM HAWAII TO THE MAINLAND SUBJECT TO STERILIZATION UNDER SUPER- 
VISION IS AUTHORIZED 
[Approved October 19, 1938; effective November 1, 1938] 
Extensive experiments have demonstrated that holding of fruits and vege- 
tables at certain prescribed temperatures for certain periods will kill all stages 
of the Mediterranean fruitfly and the melonfly. Available data suggest that 
certain fruits and vegetables may be subjected to such treatment without 
affecting their palatability and marketability. Treatment in Hawaii of fruits 
and vegetables at prescribed temperatures under supervision of inspectors of 
the Bureau of Entomology and Plant Quarantine and the handling of the 
treated products under supervision so as to prevent reinfestation will preclude 
the possible introduction of these pests into the mainland and the following 
two treatments are prescribed: 
1. Cooling until the approximate center of the fruit or vegetable reaches a 
temperature of 35° F. and holding the fruit or vegetable so the inside tem- 
perature does not exceed 35° for a period of 15 days 
2. Heating the fruit or vegetable until the approximate center reaches 110° P. 
and holding this temperature for a period of 8 hours. 
On the basis of evidence obtained and under the authority contained in the 
first proviso of regulation 2 of the rules and regulations supplemental to 
Quarantine 13, provision is hereby made for the certification of fruits and 
vegetables for movement from the Territory of Hawaii into or through any
