Evaluation of brinjal germplasm against major insect pests and predators

Abstract

A field experiment was conducted to evaluate brinjal germplasms against major insect pests and predators. The entries IC 545884 and IC 410129 against fruit and shoot borer L. orbonalis were found to be highly resistant (11.0 and 20.0%) and the entries IC354562, IC354578, IC397299, IC420406, IC427017, IC433625, IC545884 and IC545928 were moderately resistant (11.0 and 20.0%) in fruit and shoot damage, respectively. Low damage by H. vigintioctopunctata was observed in all 25 entries. Pusa hybrid 6 and IC354694 were found to be susceptible which showed low damage by Aphis devastans and Pusa hybrid 6 was damaged more by Aphis gossypi and Myllocerus. The accessions IC 545884, IC 410129 IC354562, IC354578, IC397299, IC420406, IC427017, IC433625, IC545884, IC545928 designated as resistant and fairly resistant to L. orbonalis had recorded the low population of whitefly, spotted leaf beetle, Myllocerus and aphids. Entries IC545970, IC354635, and IC354676, were found to be more attractive to coccinellids. More number of spiders found in entries such as Pusa hybrid 6, IC354578 and IC354694 whereas Pusa hybrid 6, IC383106, IC397299 and IC420650 attracted more syrphids
