The population of spiders and their predatory potency have been studied in Solanum melongena (brinjal) and Trichisanthes anguina (snake-gourd) fields in two different areas viz., Nangoor (pesticide free area) and Moongilthottam (frequently pesticide used area) of Nagapattinam District, Tamilnadu. Eight species of spiders viz., Argiope luzona (Walckenaer) (Argiopidae), Cyrtophora cicatrosa (Doleschall) (Arneidae), Chrysso argyrodiformis (Yaginuma) (Theridiidae), Hipossa pantherina (Thorell) (Lycosidae), Oxyopes lineatipes (C.L.Koch) (Oxyopidae), Oxyopes javanus (Thorell) (Oxyopidae), Peucetia viridana (Thorell) (Oxyopidae) and Lycosa pseudoannulata (Boescriberg and Strand) (Lycosidae) were recorded in both the plants in two selected areas. The population of spiders did not show significant difference between areas, plants and number of species of spiders. The predatory potency of web building spiders were estimated in the fields against insects found in the crop fields viz., Camponotus compressus (black ant) (Lalit kumar Jha), Occophylla smaragdina (tree ant) (Maxwell-Lefroy), Apis florae (honey bee) (Stebbing), Kallima inachus (butterfly) (Lalit kumar Jha), Plusia orichalcia (catterpiller) (Maxwell-Lefroy), Leuanodes orbonalis (moth) (Awasthi), Aphis gossypii (cotton aphids) (Lalit kumar Jha), Bemisia pabaci (whitefly) (Lalit kumar Jha), Culex quina (mosquitoe) (Lalit kumar Jha), Drosophila melanogaster (fruitfly) (Awasthi), Musca nebulo (housefly) (Awasthi), Amritodus alkinsoni (mango leaf hopper) (Awasthi), Macromia magnifica (dragonfly) (Awasthi), Epilachna vigintioctopuctata (beetle) (Awasthi) by counting the number of insects caught in the spider’s web and the result indicated that there has been a significant difference observed between the spider’s web-type and number of insects caught
