 ADMINISTRATIVE INSTRUCTIONS 
 THE SHIPIvIENT OF FRUITS AND VEGETABLES IROM HA\7AII TO THE 
 MAINLAND SUBJECT TO STERILIZATION UNDER SUPERVISION 
 IS AUTHORIZED 
 
 (Approved OctolDer 19, 193S; effective November 1, 193S) 
 
 Extensive experiments have demonstrated that holding of fruits 
 and vegetalDles at certain prescribed temperatures for certain periods 
 vail kill all stages of the Mediterranean fruitfly and the melonfly. 
 Available data suggest that certain fruits and vegetables may be sub- 
 jected to such treatment without affecting their palatability and mar- 
 ketabilitj'-. Treatment in Hawaii of fruits and vegetables at prescribed 
 temperatures under supervision of inspectors of the Bureau of Entomology 
 and Plant Qacrantine and the handling of the treated products under su- 
 pervision so as to prevent reinfestation will preclude the possible in- 
 troduction of these pests into the mainland and the following two treat- 
 ments 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 temperature does not exceed 35° 
 for a period of 15 days. 
 
 2. Heating the fruit or vegetable \mtil the 
 
 
 
 approximate center roaches 110 F. and hold- 
 ing 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 supple- 
 mental to Quarantine 13t provision is hereby made for the certification 
 of fruits and vegetables for movement from the Territory of Hav/aii into 
 or through any State, Territory, or District of the United States when 
 treatments are applied in Hawaii at plants designated for this purpose 
 by the United States Department of Agriculture ond under the supervision 
 of the inspectors of the Bureau of Entomology and Plant Quarantine, pro- 
 vided that in the issuance of permits fruits and vegetables so treated 
 shall be moved and handled by the treating plant and loaded on ships in 
 a manner T/hich, in the judgment of the inspectors, will preclude fruitfly 
 infestation subsequent to treatment.
