Abstract
          The effect of different doses of gamma radiation (2, 4, 6, 8 and 10 Gy) on the infective juviniles (IJs) of Steinernema carpocapsae has been studied. The results showed that there was a positively relationship between the mortality and the storage period of the infective juviniles. The susceptibility of Corcyra cephalonica and Ephestia kuehniella to unirradiated and 2 and 3 Gy gamma irradiated Steinernema carpocapsae were indicated by the daily mortality rate. It was observed that the larval mortality increased when gamma irradiated Steinernema carpocapsae was used as the lower time was needed for larval mobidity. In contrast, the reproductive rate of the Steinernema carpocapsae IJs was decreased after the irradiation.
