Determination of the dose of gamma radiation to disinfest peaches, Prunus pérsica infested with larvae of Ceratitis capitata (Wied., 1824) was made. Fruits were collected in the field, each one holding about nine larvae of the last instar of the fruit-fly. The fruits were irradiated with Cobalt-60 gamma radiation source at the following doses: 0 (control), 25, 50, 100, 200, 400, 600, 800, 1000 and 1200 Gy; at a dose rate of 58 Gy per minute. After irradiation the fruits were kept in a climatic chamber with the temperature adjusted between 23 and 27°C, and relative humidity between 65 and 75 percent, until the larvae left the fruits and were transformed into pupae and adults. It was concluded that the lethal dose of gamma radiation for larvae at the last instar, in naturally infested peaches, was 600 Gy and the dose of 50 Gy inhibited completely the emergency of adults.Downloads
