A survey was carried out to study the distribution of plant parasitic nematodes associated with fruit crops of Bhubaneswar- The capital of state Odisha, India. Around 240 soil samples were collected from the rhizosphere of fruit crops; cashew nut, guava, papaya and lime across the different places of Bhubaneswar. Nematodes were isolated by Cobb’s sieving and decanting method followed by modified Baermann’s funnel technique. Communities of plant parasitic nematodes were analysed. The analysis of nematode community revealed the association of 13 nematode species with these fruit crops. Rotylenchulus reniformis was found above pathogenic level which cause disease incidence in fruit crops in different places of Bhubaneswar. Other nematode species reflected low densities which were below pathogenic level. In consideration to prominence value of plant parasitic nematodes Rotylenchulus reniformis exhibited highest Prominence value(207.85), followed by Helicotylenchus dihystera (36.08), Tylenchorhynchus mashhoodi (21.52), Hoplolaimus indicus (19.77), Meloidogyne spp(11.66) and Aphelenchus avenae found the lowest prominence value as (3.74).So far as the free living nematodes are concerned Dorylaimids were having the highest frequency of occurrence (232) with absolute frequency (96.67%) followed by Rhabditid (93.33%)and Mononchid (80%). Dorylaimid was also having highest density (52.68) followed by Rhabditid (36.64) and Mononchid (23.79).
