Abstract

The aim of this experiment was to determine the desinfestation dose of gamma radiation in Averrhoa carambola infested with larvae of Anastrepha obliqua. Fruits were collected in the field, each having about 11 larvae in the last instar. Fruits were irradiated with the following gamma radiation doses: 0 (control), 50, 150, 300, 600 and 900 Gy. Each treatment consisted of 9 fruits (3 replications) giving the amount of 99 larvae for each treatment. After irradiation the fruits were kept in a climatic chamber with the temperature adjusted to 25 ± 5°C and relative humidity of 70 ± 5%, until larvae left the fruit and became transformed into pupae and adults. The lethal dose (LD100) of gamma radiation for larvae in the fruits was 600 Gy and the dose of 50 Gy inhibited completely the total emergency of adults.
