- 说明oe Mediterranean fruit fly pupae are separated from the dry bran in which the larvae have turned into pupae. Technicians at the International Atomic Energy Agency (IAEA)'s jaboratory at Sejbersdorf, , near Vienna, dump the bran-and-pupee contents of 4 collectime pox. 40° a chute which passes the mixture in front of a small plastic—bladed household fan turned at top speed. The mixture 1s winnowed on the same principle that farmers use in separating grain from chaff. The light- weight bran is blown away and the heavier pupae fall into 4 collecting bin: beneath. They are now ready to be stored until their exposure to cobalt radiation which aterilizes them but does not impede their erowth into adult flies. sterilized flies are released in overwhelming numbers. in areas where the fruit fly damages orchard cropSe © They mate with local flies and the rasulting eges Ste infertile. This sterile-male technique helps to control and eradicate this snsect scourge. The wind-machine with sts home-made chute is part of the inexpensive equipment perfected by IAEA entomologists to make mass rearing of the Mediterranean fruit fly possible in countries where complicated and costly lab equipment is not available. : ae oe oe oe IAEA/No. 1904 Photo: IAEA obese te Oa
