Out of one hundred cadaver of Lepidiota albistigma, ten samples were found to be positive for entomopathogenic nematodes in Sorbhog, District Barpeta, Lower Brahmaputra valley zone, Assam, India. On the basis of morphological and morphometrical studies, the isolated nematode was identified as Heterorhabditis bacteriophora.
