Abstract
The purpose of the present study was to document the various species of predatory spiders present in cotton and paddy agro-ecosystems of ManamaduraiTaluk, Sivagangai district, Tamilnadu, India. The research was carried out from February 2020 to September 2021.The Main aim of this study was to determine the species richness and relative abundance of spiders in cotton and paddy fields.Pitfall traps, hand picking, visual counting and sweep net methods were used to collect spider samples on a bimonthly basis. A total of 7,553spiders comprising 55 species, 30 genera and 9 families were recorded. Araneidae family contributed a major share to the overall count of spiders, accounting for 42.12 % of the total. The most dominant species was Argiopeanasuja(4.47 ) followed by Neosconarumpfi, Neosconatheisi and Oxyopesjavanusin cotton field, while in paddy field the most dominant species was Argiopepulchella followed by Tetragnathaextensa and Tetragnathaelongata.The highest species richness was found in the cotton plantation with 37 species belonging to 25 genera and paddy field recorded 29 species belonging to 16 genera under9 families. Diversity indexes were higher at paddy (H’ =1.49; 1-D = 0.71) and lower at cotton (H’ = 1.40; 1-D = 0.70). Similarity index revealed high resemblance in species composition between cotton and paddy. The findings of the present study will help in the pest management techniques that can be implemented in cotton and paddy growing areas throughout the world.
