abstract
The results on pathogenicity of indigenous EPN isolates viz., Heterorhabditis spp.(PKV-1), Heterorhabditis spp.(CICR Brown), Steinernema spp. (CICR-White) and Heterorhabditis spp. (PKV-Guava) from Nagpur against the 5th instar larvae of Corcyra cephalonica and Galleria mellonella revealed that highest mortalities observed in EPN sample CICR-Brown in the treatment concentration of 50IJs/20µl which were 94.28%, in 30IJs/20µl were 82.85% and 74.28%, 74.28%, 68.57%, 60% and 57.14% in the treatment concentration 25IJs/20µl, 20IJs/20µl, 15IJs/20µl, 10IJs/20µl, 5IJs/20µl respectively. However, in case of CICR-white the highest mortality was observed in 50IJs/20µl that was 68.57% and 65.71%, 62.85%, 62.85%, 60%, 57.14%, 54.28% in the treatment concentration of 30IJs/20µl, 25IJs/20µl, 20IJs/20µl, 15IJs/20µl, 10IJs/20µl, 5IJs/20µl respectively. In case of greater wax moth, the highest mortalities observed in EPN sample CICR-Brown in the treatment concentration of 50 IJs/20 µl which were 97.14%, and 91.42%, 82.67%, 68.57%, 68.57%, 67.56%, 60.36% mortality were observed in the concentration of 30IJs/20µl, 25IJs/20µl, 20IJs/20µl,15IJs/20µl, 10IJs/20µl, 5IJs/20µl respectively.
