In every country that grows brinjal (Solanum melongena L.), the Brinjal Shoot and Fruit Borer (BSFB), Leucinodes orbonalis Guenee, is a destructive pest. In the Horticultural College and Research Institute for Women, Tiruchirappalli, 46 genotypes of brinjal were tested against the pest using a randomised block design with three replications. A significant pest of brinjal that mostly targets the plant's shoots and fruits is brinjal shoot and fruit. To screen the various brinjal genotypes, criteria such as the percentage of shoot and fruit infestation brought on by BSFB and the additional damage scale recorded were used. Out of forty six entries, only six brinjal accessions IC 136451, IC 136231, IC 136061, IC 136296, IC 546016, and IC 089964 were found to be moderately resistant, with mean fruit damage ranging from 11 to 20%, according to the screening results. Thirteen accessions were found to be susceptible with 31–40% fruit damage, while sixteen more accessions IC 136249, IC 136309, IC 383099, IC 136250, IC 112341, IC 215021, IC 136302, IC 136546, IC 127023, IC 090982, IC 136299, IC 090925, TRYSM 1, TRYSM 2, TRYSM 3, and TRYSM 6—were found to be tolerant with 21–30% damage intensity. Ten brinjal accessions were classified as very vulnerable if their mean percentage damage intensity was higher than 40. The resistance breeding program can use the moderately resistant genotypes to combat BSFB, Leucinodes orbonalis.
