Abstract:

A total 200 soil samples were collected from tea plantation areas of district, Jorhat, Assam and were assessed for entomopathogenic nematodes using the Galleria baiting technique. Out of 200 soil samples, EPN was found in 1 soil sample collected from Tea plantation, Chetiagaon, Jorhat and designated as EPN-H-1. Morphological and morphometrical characters were used for the identification of nematode isolate. The measurements were expressed in % ratios and Means ± SD ranges. The IJ of EPN-H-J-l showed close similarity with H. bacteriophora with respect to head shape, ratio b, D% and E%, but exhibited minor differences from the type measurements by having lower tail length (82 vs. 91). The males of this isolate showed close similarity with H. bacteriophora with respect to head shape, anal body width, gubernaculum length but exhibited minor differences from the type measurements by having higher esophagus length (107 vs. 103) and tail length (34 vs. 28). The hermaphroditic and amphimictic females of this isolate exhibited differences from the type measurements by having lower body length, lower body width and lower anal body width which are considered as intraspecific variations of H. Bacteriophora. Comparative analysis revealed that an EPN-H-1 isolate belong to the Heterorhabditis bacteriophora as earlier described by Poinar, 1976 from Brecon, South Australia in respect of body length, body width, tail length etc.
