Abstract

 

The effect of different doses of gamma radiation (2, 4, 6, 8, and 10 Gy) on the infective juveniles (IJs) of Steinernema carpocapsae was studied. The results showed a positive correlation between mortality and the storage period of the infective juveniles. The susceptibility of Corcyra cephalonica and Ephestia kuehniella to both unirradiated and gamma-irradiated (2 and 3 Gy) Steinernema carpocapsae was evaluated based on daily larval mortality. It was observed that larval mortality increased when gamma-irradiated nematodes were used, as they required less time to cause larval morbidity. In contrast, the reproductive rate of the nematodes decreased after irradiation.
