Abstract

An investigation was disbursed to guage the antifeedant activity and toxicity of Punica granatum, Cassia fistula and Erythrina variegata extracts (ethyl acetate, hexane, chloroform and methanol) against the fourth arthropod larvae of Spodoptera litura below laboratory conditions within the Annamalai University, Chidambaram, India. The P. granatum, C. fistula and E. variegata methanol extract exhibited robust antifeedant and toxicant activity against the larvae of S. litura once applied either on leaf discs or incorporated into artificial diet. Below selection conditions the antifeedant index calculated over 96 hours. Consumption by, the fourth instar larvae of leaf discs swaybacked in 0.5, 1.5, 3.0 and 5.0% concentrations. Among the plants screened, P. granatum showed higher antifeedant activity against the larvae of S. litura. methanol extracts of P. granatum (83.8%), C. fistula (73.2%) and E. variegata (56.4%) showed higher antifeedant activity. the very best concentration of (5.0%) P. granatum methanol extract was found to be relatively a lot of to LC50 and LC90 values of (1.364% and 3.987%) than those of C. fistula (1.605% and 4.523%) and E. variegata (1.832% and 4.982%) at 96 hours exposure. Hence, it should recommend its use for dominant the agriculture pest, S. litura.
