Screening of Sesame Genotypes against Major Insect-Pests

Abstract

An investigation was carried out at research farm, college of agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior to evaluate sesame genotypes for susceptible/resistance to major insect pests. Out of Ten sesame genotypes, TKG-501 and SCS-551 showed lowest  plant damage, flower damage and  capsule damage against sucking insect pests namely; white fly (Bemisia tabaci Genn.), jassid (Amrasca devastans Ishida) and til hawk moth (Acherontia styx Westwood) while, the highest per cent of infestation showed in TKG-55. For leaf roller and capsule borer (Anigastra catalaunalis), TKG-501 and TKG-518 genotypes showed lowest infestation; whereas JTS-8 and SCS-551 showed highest  plant damage, flower damage  and  capsule damage respectively. TKG-501, TKG-518 and TKG-55 showed lowest plant damage, flower damage (%) and  capsule damage against gall fly (Asphondylia sesame Felt) and mirid bug (Nesidiocoris sp.) while, the highest per cent of infestation showed in JTS-8 and TKG-308 genotypes.
