Study was conducted to determine the distribution of the entomopathogenic nematodes in apple growing areas in Karaman province, Turkey and their efficacy on Galleria mellonella (Lepidoptera: Pyralidae). Soil samples were collected from 130 apple orchards in April 2012 and 2013. Entomopathogenic nematodes were found in 25 samples (19.23%). Entomopathogenic nematodes species isolated: Heterorhabditis bacteriophora Poinar, 1976 (Rhabditida: Heterorhabditidae) (16.92%) and Steinernema feltiae (Filipjev, 1934) (Rhabditida: Steinernematidae) (2.3%). Entomopathogenic nematodes distributed in low sand content and low-fertilized soils in Karaman province. The efficacy of H. bacteriophora and S. feltiae on G. mellonella was 100% after 72 h with 50 infective juveniles at 25 degree C.
