ResumoThe entomopathogenic nematodes, Steinernema weiseri, was firstly isolated in Beytepe Campus of Hacettepe University, in Ankara, Turkey and S. feltiae Rhabditida: Steinernematidae , which was found in Ankara University Campus. In the present study, reproduction capacities and effectiveness of the both entomopathogenic nematodes were compared in variable conditions. The reproduction capacities were examined at the following temperatures; 10, 15 and 20 ºC and the doses of 10, 50 and 100 infective juvenilesdauer juveniles DJs in the last instar larvae of greater wax moth, Galleria mellonella L. Lep: Pyralidae . New generation DJs of each species, which produce within the host larvae and emerging from cadaver were counted and the results showed that S. weiseri was more productive than S. feltiae in all experimental conditions. Effectiveness of the both species on the last instar G. mellonella larvae as LD50 was calculated 48 h after penetration. According to the results, S. weiseri is more effective than S. feltiae. The present results indicated that S. weiseri can be more useful for biological control
