Induced resistance to Helicoverpa armigera through exogenous application of jasmonic acid (JA) and salicylic (SA) was studied in groundnut genotypes (ICGV 86699, ICGV 86031, ICG 2271 1697) with different levels insects the susceptible check JL 24 under greenhouse conditions. Activities oxidative enzymes amounts secondary metabolites proteins were quantified at 6 days after JA SA application/insect infestation. Data also recorded on plant damage H. larval weights survival.Higher enzymatic activities observed insect-resistant pretreated then infested than 24. The suffered lower insect resulted poor survival larvae In some cases, showed similar effects.JA induced activity antioxidative plants against armigera, reduced its growth development. However, response greater SA, damage, survival, suggesting that can be used as a component pest management groundnut.
