A survey of nematode communities associated with chilli fields in eight localities of lower Sindh was conducted. In all eight species were recorded viz., Meloidogyne sp. larvae; Helicotylenchus indicus; Pratylenchus penetrans; Tylenchus sp. larvae; Pratylenchus thornei; Tylenchorhynchus annulatus; Psilenchus hilarulus; Hoplolaimus indicus and Aphelenchus avenae. A principal component ordination showed the relationships between localities and the species. Cluster analysis revealed the grouping of the nematode communities. Two main groups could be recognized, a small group having large populations of Meloidogyne sp. larvae and a large group comprising of communities with saprophytic nematodes and parasitic species such as Helicotylenchus indicus, Tylenchorhynchus annulatus and Pratylenchus spp. with variable densities.
