Abstract:
A survey was conducted for prevalence of entomopathogenic nematodes in vegetable growing areas of the district Jorhat, Assam. A total of 200 soil samples were collected from rhizosphere region of different vegetable crops. Soil samples were baited using Galleria mellonella larvae for the presence of steinernematid and heterorhabditid nematodes. Among the soil samples collected, five samples were tested positive for heterorhabditid isolate. From the morphological and morphometrical examinations, the isolate was identified as Heterorhabditis bacteriophora.
