The gamma radiation was given to 4 day and 8 day old pupae of uzi flies at two effective doses of 1.5 and 2 kr and the observations were recorded for two generations and the study was carried out in the department of Sericulture, UAS, GKVK, Bengaluru. The pre-mating duration was significantly different between 1.5 and 2 kr when 4 day old pupae and 8 day old pupae were irradiated, the mating duration was not significantly different between 1.5 and 2 kr when 4 day old pupae and 8 day old pupae were irradiated. The ovipositional duration showed a significant difference between 1.5 and 2 kr when 4 day old pupae were irradiated and no significant difference between 1.5 and 2 kr when 8 day old pupae were irradiated in the first generation. Whereas in the second generation, the pre-mating duration, mating duration and ovipositional duration did not vary significantly between 1.5 and 2 kr when 4 day old pupae and 8 day old pupae were irradiated. | Pre-mating, mating and ovipositional duration of gamma irratated uzi fly, a parasitoid of mulberry silkworm Bombyx mori L.
