Online published on 23 July, 2019. Abstract A study was conducted during kharif seasons of 2016 and 2017 at the Chaudhary Charan Singh Haryana Agricultural University, Hisar to study the quantitative and qualitative losses by the infestation of sesame leaf webber and capsule borer, Antigastra catalaunalis in HT-1 and HT-2 variety of sesame. The experiment was conducted under both protected and unprotected conditions in paired plot design with three replications. Plot size was kept 2.7 x 1.8 m2 and distance between row and plant was maintained at 30 and 10 cm during each season. Pooled data of both years revealed that pod damage in both the varieties varied from 19.72 to 21.62% under unprotected condition while in protected condition it varied from 3.02 to 3.12%. Maximum yield was recorded in HT-2 (921.42 kg/ha) under protected condition while minimum yield was observed in HT-1 (521.48 kg/ha) followed by (555.27 kg/ha) under unprotected condition. Avoidable yield loss due to A. catalaunalis was 35.16 and 39.73% in the varieties HT-1 and HT-2, respectively after three sprays of quinalphos. Total protein and crude fat contents of seeds obtained from damaged pods were significantly lower in both varieties viz., HT-1 and HT-2 as compared to seeds obtained from undamaged pods. This is a big impact on the nutritional quality. However, fibre, ash and moisture contents were not affected to that extent.
