An investigation was carried out in the Department of Entomology, College of Horticulture,Dr. Y.S.R. Horticultural University, V.R. Gudem to screen brinjal genotypes for tolerance/resistant to major pests. Out of 44 brinjal genotypes tested,IC-090050 and IC-090199 showed lowest infestation fruit and shoot borer while Irapaduguda-W showed highest. Based on percent fruit damage, twelve genotypes viz., IC-090050, IC-090199, EC-169084, EC-316742, EC-316309, IC-089955, EC-316273, Bhagyamathi, IC-090674, EC-169089, IC-110949 and IC-111392 were found to be moderately resistant to borer damage. The lowest percent fruit damage by Leucinodes orbonalis was observed in the genotype IC-090050 (10.26%) followed by IC-090199 (12.75%), EC-169084 (13.03%) and the lowest percent shoot damage was observed in the genotype IC-090050 (4.11%) followed by IC-090199 (4.21%) EC-169084 (4.32%) which were statistically on par with one another. Among 44 genotypes of brinjal tested, none of them were immune to jassid infestation. Nevertheless IC-090050 with 9.90 percent hopper burn intensity was considered as highly resistant to Amrasca devastans which recorded 1.41 and 2.74 times lesser than Bhagyamathi and Dommeru local respectively in percent jassid intensity. Least number of whitefly and hadda beetle population per three leaves was noticed in IC-127074.
