Comparison of Some Biological Characterizations of the Entomopathogenic Nematodes, Steinernema weiseri and S. feltiae (Rhabditida: Steinernematidae), Isolated in Turkey

2006 Journal of Agricultural Sciences  
The 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

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 LD 50 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.
