Abstract

Spiders are one of the most numerous groups of terrestrial predators and these are found in diverse environments such as agro ecosystems and nearby areas.  This work evaluated spider richness, abundance, and species composition.  A periodical survey and a systematic study of spider fauna were undertaken for a period of three months from October 2016 to December 2016 in agrofield of Melmangalam, Periyakulam Taluk, Theni district, Tamilnadu, India.  Handpicking and Net sweeping method was used to collect the spiders.  In total 1226 specimens were collected from the study area during the period representing 4 families of spiders and 19 species of spiders.  The family Araneidae and Salticidae was prominent family with 6 species of spiders. The family Oxyopidae was the least recorded family with two species. The family Araneidae was most abundant with maximum number of individuals (458) and Oxyopidae was the least abundant with less number of individuals( 110).  The richness indices (R1 and R2) showed that the species richness was maximum for the family Salticidae during the study period.
