Abstract

Biodiversity can be simply defined as the variety of all types of living organism. Spiders are among the most diverge groups on earth, which received the seventh ranking in global diversity after the sixth largest insect orders. Spiders are major playing a vital role in the forest ecosystem is the spiders. In our present study spiders were collected from cotton field area of Thailakulam, Srivilliputtur taluk, Virudhunagar district, Tamil Nadu, India. The spiders were collected from September 2012 to February 2013, using the sweep net, hand ricking, aerial netting, beating method and leaf litter method etc. During this study, 19 species belonging to 18 genera and eight families were collected from cotton field. The scientific knowledge up to species level and taxonomic position and seasonal variation has been studied. The family Salticidae (31.57) harboured highest population followed by three families such as, Araneidae, Lycosidae and Oxyopidae (15.78) and the least number of spiders recorded under the family, Tetragnathidae, Gnaphosidae, Sparassidae and Thomisidae. The richness of the spider species based on the fluctuation in different months may be the seasonal variation and harvesting in the nearby fields in the study area. The population of spiders was abundant species richness and diversity was high during the month of September 2012 to February, 2013. Mean, standard deviation and diversity indices were calculated.
