Induced defense was studied in three groundnut genotypes ICGV 86699 (resistant), NCAc 343 (resistant) and TMV 2 (susceptible) response to Spodoptera litura infestation jasmonic acid (JA) application. The activity of the oxidative enzymes [peroxidase (POD) polyphenol oxidase (PPO)] amounts other host plant components [total phenols, hydrogen peroxide (H2O2), malondialdehyde (MDA), protein content] were recorded at 24, 48, 72 96 h JA pretreated (one day before) plants infested with S. litura, application simultaneous understand against damage. Data on damage, larval survival weights also recorded. There a rapid increase activities POD PPO quantities total H2O2, MDA content + plants. All showed quick by increasing defensive compounds. Among all genotypes, higher induction most parameters. Reduced low observed It suggests that pretreatment elicitors, such as could provide more opportunity for herbivores.
