Species Composition and Relative Abundance of Predatory Spider Fauna in Sunflower Ecosystem

Résumé

Studies were conducted to know the species composition and Relative abundance of predatory spider fauna in sunflower crop ecosystem at Zonal Agricultural Research Station (ZARS), UAS, GKVK, Bengaluru. The results revealed that about 29 species of spiders were found and recorded in the sunflower ecosystem belonging to different families viz., Araneidae (10 species), Salticidae (7 species), Thomisidae (3 species), Oxyopidae (3 species), Tetragnathidae (2 species), Miturgidae (2 species), Clubionidae and Linyphiidae (1 species each). During Kharif 2022, among the dominant spiders species maximum relative abundance was recorded by the Oxyopes sp. (30%) followed by Thomisus sp. (25.79%), Cheiracanthium sp. (11.05%), Telamonia sp. (8.43%), Peucetia viridana (7.89%) and Neoscona sp. (7.36). Whereas, remaining species contributed 9.48 per cent towards species composition. However, in Kharif 2023 highest relative abundance was recorded by Oxyopes sp. (28.81%) followed by Thomisus sp. (23.75%), Peucetia viridana (15.25%), Cheiracanthium sp (8.47%), Neoscona sp. (6.78%) and Telamonia sp. (5.12%), while the remaining species contributed 11.82 per cent to the species composition.
