摘要

 The mean populations of spiders in three different places like Thayilpatti, Madathuppatti and Vembakkottai, Virudhunagar district, Tamil Nadu, India were studied. In these areas, twenty common species of spiders belonging to six families from these three selected areas were collected and identified. The collected spiders belonging to the family, Salticidae, Oxyopidae, Araneidae, Lycosidae, Gnaphosidae and Sparassidae. In this study, two species of spiders were observed, one is web weaver and another one is non – web weaver. The web weaving spiders belonging to the family Araneidae and Lycosidae. The non-web weaving spiders belonging to the family Salticidae, Oxyopidae, Gnaphosidae, Lycosidae and Sparassidae. P. viridana, O. birmanicus, O. hindostanicus, P. latikae and A. anasuja a dominant predator recorded in these three selected areas. The population dynamics of the individual spider species in different months showed that the population of spider species mainly P. vridana, O. birmanicus, O. hindostanicus, A. anasuja, N. lugubris, P. latikae, C. cicatrosa and L. pseudoannulata were very high throughout the study period. The increase in the spiders density suggested that the spider density is influenced by the increase in prey density
