Isolation and characterization of two heterorhabditid and one steinernematid nematodes from Egypt
International Journal of Nematology 16 (1), 7-12
Abstract: Three Egyptian strains of entomopathogenic nematode are described: two isolates are identified as Heterorhabditis bacteriophora and a third one as Steinernema carpocapsae. They were recovered from soil samples collected from El-Behira, Fayoum and South Sinai governorates during a survey for entomopathogenic nematode. Samples were identified through crossbreeding tests and by the combined morphological and morphometrical characters of various stages of the nematodes. The heterorhabditid nematodes were cross bred with Heterorhabditis bacteriophora, H. indica, H. marilatus and H. zealandica. Only males and females of H. bacteriophora were able to mate with both strains and form second generation. The steinernematid strain was cross bred and matched with Steinernema carpocapsae.
