A field study was conducted during Kharif season 2014-15 to determine the efficacy of different insecticides against semilooper Thysanoplusia orichalcea (Fab.) in soybean ecosystem in the insectory premises of Agricultural Entomology Section, College of Agriculture Nagpur. Least cumulative average number larvae (0.05/ml) was recorded in treatment of Fenvalerate 20 EC @ 0.50 ml/l (T7) found to be superior compared to other treatments. The next effective treatments were emamectin benzoate 5 SG @ 0.3 g/l (T6 : 0.06/ml/l) and also in Spinosad 45 SC @ 0.25 ml/l (T3:0.07ml/l), Indoxacarb 15.8 EC @ 0.60 ml/l (T5:0.08ml/l) found to be at par with T6 and T3. However, the treatment Neem Oil 2 per cent (T2) recorded 0.78 larvae/mrl. Whereas, NSE @ 5 per cent (T1:0.95ml/l) and Beauveria bassiana 1×108 CFU @ 4 g/l (T4:0.99/mrl) were found to be least effective in reducing larval population/mrl. Maximum mean larval population (1.48/ml/l) was recorded in control (Water spray; T8). Fenvalerate 20 EC @ 0.50 ml/l, Indoxacarb 15.8 EC @ 0.60 ml/l, Spinosad 45 SC @ 0.25 ml/l were found to be most effective treatments which recorded highest yield of 21.05 q/ha, 20.10 q/ha and 19.02 q/ha, respectively. From the seed production point of view Fenvalerate 20 EC @ 0.50 ml/l, Indoxacarb 15.8 EC @ 0.60 ml/l, Spinosad 45 SC @ 0.25 ml/l were most effective in recording highest yield.
