EVALUATION OF SESAME VARIETIES FOR RESISTANCE TO SESAME LEAF ROLLER AND CAPSULE BORER, ANTIGASTRA CATALAUNALIS (DUP.)AJAY KUMAR YADAV, AKHTER HUSSAIN, SANJU PIPLODA AND SUMITRA CHOUDHARY
Investigations on âScreening of sesame varieties for resistance against leaf roller and capsule borerâ were conducted at Agronomy farm and Department of Entomology, S.K.N. College of Agriculture, Jobner during Kharif, 2018. Leaf roller and capsule borer, Antigastra catalaunalis were recorded as major insect pests of sesame during the year of study. The infestation of A. catalaunalis commenced in the second week of August and reached its peak in the last week of August during 2018. Out of 10 varieties of sesame screened against A. catalaunalis none was found immune. RT-346 and RT-54 were categorized as least susceptible, while, the varieties RT-46 and Pragati as highly susceptible against leaf roller and capsule borer. The moderately susceptible varieties reported were RT-125, RT-103, JTS-8, TKG-55, RT-127 and TKG-22. The morphological characters of these varieties viz., no. of leaves, no. of branches, no. of capsules and trichome density had a significant negative correlation with the population of A. catalaunalis.
