Abstract

Contact toxicity of three plant essential oils was evaluated against six days old larvae of Spodoptera litura (Fab), at 10,000ppm and 20,000ppm. Vetiveria zizanioides oil was found to be most toxic at 2 % concentration giving 93.33 % mortality 12 hours after exposure followed by Jatropha curcas oil (63.33 %) and (60.00 %) at 2 and 1 % respectively. At 48hours after exposure khas oil at 2 % gave maximum mortality (100 %) followed by J. curcas oil (73.33 %) and (63.33 %) mortality at 2 and 1 % respectively. Hedychium spicatum oil did not show any significant larval mortality.
