Abstract
Ten promising germplasm lines and three checks (VRI 1-Local check; TC-25 Susceptible check; SI-250 Resistance check) of sesame (Sesamum indicum L.) exhibiting different genetic and regional diversity were screened against shoot webber and capsule borer (Antigastra catalaunalis Duponchel) under net house condition during rabi season 2019-20 which were already found promising under open field condition at Regional Research Station, Vriddhachalam, Tamil Nadu. Among the entries tested, three entries viz., B-7-11, SI 2116, and GRT-83148 under artificial screening as well as feeding preference study were recorded less than 10 per cent plant damage and were classified as resistant.
