Abstract
An extensive survey was conducted to determine the plant parasitic nematodes associated with Solanum melongena ,grown in the Banda district of Uttar Pradesh, India. Eleven genera of plant parasitic nematodes, viz., Aphelenchoides, Helicotylenchus, Hemicycliophora, Meloidogyne, Paratylenchus, Pratylenchus, Rotylenchulus, Rotylenchus, Scutellonema. Tylenchorhynchus and Xiphinema were found associated with S. melongena. Among the 11 genera of the nematodes, Meloidogyne was widely spread in all the examined localities of Banda district, except at Atarra. Population density and diversity of nematodes in all the soil samples were not uniform. The genus Meloidogyne showed maximum absolute frequency and relative frequency, followed by Aphelenchoides, Helicotylenchus, Hemicycliophora, Rotylenchulus, Pratylenchus, Tylenchorhynchus, Paratylenchus, Scutellonema, Xiphinema, and Rotylenchus. The value of absolute and relative densities were highest in Meloidogyne followed by the Hemicycliophora , Rotylenchulus, Pratylenchus, Aphelenchoides, Helicotylenchus, Rotylenchus, Tylenchorhynchus, Paratylenchus , Xiphinema and Scutellonema. Moreover, the highest prominence value was observed for Meloidogyne followed by Hemicycliophora, Rotylenchulus, Pratylenchus, Aphelenchoides, Helicotylenchus, Tylenchorhynchus, Paratylenchus , Rotylenchus, Xiphinema and Scutellonema.
