oa Journal of the Entomological Society of Southern Africa - Cold sterilisation and fumigation for control of false codling moth, Cryptophlebia leucotreta, in export citrus fruit



Experimental fumigation of citrus with ethylene dibromide (EDB) for two hours at a dosage rate of up to 20 mg/litre, was found to be inadequate for a complete kill of all stages of the false codling moth. For this reason, combinations of EDB fumigation and cold storage were tested, resulting in the development of a successful schedule consisting of a 2-hour fumigation with EDB at 16 mg/litre followed by cold storage for 18 days at 4,4 � 0,5�C.
