Abstract

In round numbers the 100 strains of entomopathogenic nematodes were isolated through the investigation of cultivated including the ginseng forming cultivated and forest soil samples by silkworm trap. The 28 strains of nematodes were selected among the isolated entomopathogenic nematodes that were confirmed the pathogenicity against Holotrichia morosa, Hoiotrichia diomphalia and Ectinus sericeus, the pest of korean ginseng and silkworm. Pathogenicity of the 2025, 2027, 2028, 2034, 2039 and 2057 strains was excellent. Selected entomopathogenic nematodes are classified of two species by morphologiacl and molecular studies, which were Sterinernma carpocapsae sp. and Diplogaster lethier sp.. Diagnostic characters include body length, lateral field pattern, tail shape and so on. The DNA sequences of the ITS region of rDNA shows similar to S. carpocapsae and .D. lethier. Isolated entomopathogenic nematodes were demonstrates that are quite within the realms of possibility for biological control agents of the pests of Korean Ginseng.
