Abstract

A survey of nematodes associated with chilli in Hyderabad and Karachi district, Sindh, Pakistan was conducted in 2005 season. Ten localities were surveyed in the two districts and samples of rhizosphere soil were collected. In all eleven stylet bearing nematode genera and twelve species were recorded . The population densities were measured and highest density was that of Psilenchus spp. ( mean = 132 / 200 cm3) followed by Hoplolciimus indicus (62 / 200 cm3) and Pratylenchus spp. (52/200 cm3). A cluster analysis of nematodes data of localities was performed that yielded two group of localities. The first group comprises of two subgroups. Subgroup la is characterised by the presence of Hoplolciimus indicus. The subgroup lb is characterised by the presence of Meloidogyne jovanica, Helicotylenchus indicus and Meloidogyne incognita. The second group has Tylenchorhynchus annulatus and Xiphinema spp., with high abundance in nematode communities.
