A survey of agricultural fields near Yamuna in Faridabad, Haryana was conducted to study the diversity and community structure of the soil inhabiting nematodes. A total of 32 genera belonging to 7 orders and 22 families were recorded. In terms of abundance, order Tylenchida was most abundant while in terms of number of genera, order Rhabditida was most frequent. Out of 32 genera, 10 viz., Pratylenchus, Psilenchus, Helicotylenchus, Hemicriconemoides, Hoplolaimus, Meloidogyne, Rotylenchulus, Tylenchorhynchus, Hirschmanniella, Xiphinema belonged to plant-parasitic nematodes. Overall Meloidogyne was the most abundant among all the nematode genera.

Summary The distribution and community structure of plant-parasitic nematodes associated with betel (Piper betle) vine and their relationship with soil chemical properties were investigated in four major growing regions of West Bengal, India. Ordinary kriging method was applied to infer the patterns of spatial distribution of major plant-parasitic nematodes across the growing regions. Meloidogyne and Rotylenchulus were found to be the most abundant genera in betel vine crops in all growing regions. Co-inertia analysis between soil properties and nematode abundance indicated that soil chemical characters significantly affect abundances of plant-parasitic nematodes. The type of betel vine crop (sweet and bitter) also has a significant effect on the abundance of plant-parasitic nematodes, with the highest abundance of Meloidogyne reported from the bitter type of betel crop. Spatial distribution depicted a higher abundance of Meloidogyne throughout the North Bengal growing region. Root-knot and reniform nematodes are two important plant-parasitic nematodes of betel vine that might cause economic yield loss to the growers in West Bengal.
