Abstrakt: Preliminary experiments in Israel showed that sterile Mediterranean fruit flies, Ceratitis capitata (Wiedemann), could not be scattered successfully from airplanes as pupae. Concussion caused only small losses, but exposure to sunlight and removal by ants killed almost all the pupae before the adults could emerge. For this reason we developed at the IAEA laboratory in Austria a method by which adults emerged in paper bags filled with wood-wool. These bags were released through a suction tube which projected beneath the fuselage of an airplane. Fixed knives slit open the bags in their passage down the tube and the bag contents were torn out by a spike fixed on a rail projecting behind the tube. Flies released in this way survived as well as ground-released adults. Survival was considerably improved by impregnating the wood-wool with 10% sucrose so that the adults could feed before they were released. By this method adults of approximately 1x106 pupae can be released from 100 bags occupying a total of 1-1.5 cubic meters.
