摘要

Based on pooled analysis of data of two seasons, two foliar sprays of abamectin @ 125 mL ha~(-1), at 10 days interval, first at 45 and second at 55 days after transplanting resulted in the lowest mean population of two spotted spider mite Tetranychus urticae Koch (Acari:Tetranychidae) on brinjal (Cv. Local) (1.77 mites cm~(-2) leaf area). In comparison, fenpropathrin, spiromesifen and dicofol recorded 7.78, 9.12 and 11.71 mites cm~(-2) leaf area, respectively and the untreated check 22.94 mites cm~(-2) leaf area. Abamectin application up to 250 mL ha was moderately safe to the predatory mite, Amblyseius tetranychivorus and coccinellids while other insecticides were toxic. All doses of abamectin from 60 to 250 L ha~(-1) were equally effective in recording brinjal yield which ranged from 17.37 to 17.83 tonnes ha~(-1) as against 13.00 tonnes ha~(-1) in untreated control.
