Sixty sesame genotypes including 7 local cultivars were evaluated during 2016 for resistance against sesame leaf webber and capsule borer, A. catalaunalis (Dup.) at ZARS, V. C. Farm, Mandya. Among the 60 genotypes evaluated AVT-8, IVT-15, IVT 5-1, IVT-9 and Kanakapura local were reacted as highly resistant (HR) with mean pod damage of 1.15, 1.84, 1.86, 1.94 and 4.47%, respectively along with cumulative leaf, flower and pod damage score of 1.00 while, four genotypes viz., AVT-3, AVT-1, IVT-23 and IVT-27 in which, the leaf, flower and pod damage were varied between 9.76 to 14.20%, 3.58 to 5.88%, and 1.42 to 1.65%, respectively and were rated as resistant (R) with a cumulative score of 1.66. Whereas, seven genotypes viz., IVT-5, IVT- 7, IVT -11, IVT-13, IVT-21, AVT-10, AVT 4-2, Shivalli local were reacted as susceptible (S) with leaf, flower and pod damage varied between 30 to 40%, 15 to 20%, and 6 to 8%, respectively. Out of 60 genotypes evaluated under high pest pressure, 43 genotypes were designated as highly susceptible (HS) with the mean leaf, flower and pod damage of more than 40.00, 20.00 and 8.00%, respectively.
