Nematodes associate with big fruit trees and their community analysis survey of state Odisha, India

Abstract

Around 240 soil samples were collected from the rhizosphere of fruit crops across the different places of Odisha. That revealed the presence of Rotylenchulus reniformis (120.63), Tylenchorhynchus mashhoodi (108.97), Hoplolaimus indicus (40.76), Hemicriconemoides mangiferae (32.10), Helicotylenchus dihystera (20.00), Xiphinema insigne (17.34), Caloosia heterocephala (10.80), Pratylenchus coffeae (7.20), Aphelenchus avenae (6.36), Dorylaimid (65.06), Mononchid (29.73), Rhabditid (13.40) exhibiting varying population densities. Among the different plant parasitic nematodes, Hoplolaimus indicus was highest frequency of occurrence (168), with absolute frequency (70%). Moreover Rotylenchulus reniformis found the most prominent species with higher prominence value (96) followed by Tylenchorhynchus mashhoodi (90.08), with the lowest prominence value (2.08) recorded in Pratylenchus coffeae. Among free living nematodes Dorylaimid were highest frequency of occurrence (240), with absolute frequency (100%) followed by Mononchid and Rhabditid (86.67%), (75%). Dorylaimids were also having the highest prominence value (65.06) followed by Mononchid (27.68) and Rhabditid (11.60).
