The population of total predatory fauna of spiders occurring in brinjal crop at sprayed and unsprayed areas study has been conducted. The results revealed that, average number of spiders recorded was highest in unsprayed area, i.e., Attur Farm, 3.20, while at Chikkaballapur and Doddaballapur the average spiders recorded were 1.79 and 2.01 per 10 plants, respectively during Kharif season. Similar, results were observed during Rabi and summer season also under both sprayed and unsprayed areas. The maximum relative abundance of Peucetia viridana was most frequently recorded which about 12 percent of the spider population was and next most abundant species was Oxyopes birmanicus (8.20%) in Kharif season, Oxyopes rukuminiae (8.33%) in Rabi season and O. birmanicus (9.01%) in summer season in unsprayed (Attur Farm) area. In sprayed areas, viz., Chikkaballapur and Doddaballapur P. viridana and O. birmanicus were recorded as two most abundant species constituting 12.0 to 16.9 percent of the population, in addition during Rabi season; O. assamensis was also recorded as an important species.
