An experiment was conducted during Kharif 2014 to 2016 at ARS, MPUAT, Banswara. The objective was to estimate avoidable losses due to defoliators in seed yield of soybean on four varieties viz., JS-335, JS-93-05, JS-95-60 and RKS-24.The semilooper population varied from 1.21 to 3.96 larvae/mrl on different soybean varieties. The maximum population was observed on JS-335 then JS-93-05 and JS-95-60 was significantly lower semilooper than that on RKS-24. Similarly, from the pooled data of three years, it is evident that the Spodoptera litura larval population varied from 1.54 to 4.77 larvae/mrl on different varieties of soybean. It was maximum on JS-335and minimum on JS-95-60 and JS-93-05. Under protected conditions, the minimal S. litura larval incidence of less than one larva/mrl was observed in all the soybean varieties. From the data it was evident that maximum yield loss in JS-335 during 2014 and 2016 corresponded with the maximum population of semilooper and S. litura larvae.
