- The objective of this research was to evaluate the effect of gamma irradiation on fruit fly (Ceratitiscapitata) eggs and larvae (1st, 2nd and 3rd instars) in ‘Valencia’ oranges, and evaluate the effect of the irradiation on the chemical composition of the fruits. The fruits were artificially infested with the immature stages of the fruit fly and treated with 0, 10, 20, 30, 40, 50, 100, 150 and 200 Gy Cobalt-60 doses. The treatment with gamma irradiation can be recommended for quarantine treatment of all immature stages of C. capitata in ‘Valencia’ oranges if applied at the doses of 72.88 Gy. Larvae of 3rd instar are more radio resistent when compared to eggs and larval of 1st and 2nd instar. The doses of gamma radiation used do not affect the chemical proprieties of ‘Valencia’ orange fruits.
