Antifeedant and toxic activity of Melia azedarach seed extracts against Helicoverpa armigera


, : Antifeedant and toxic activity of Melia azedarach seed extracts against Helicoverpa armigera. Pesticide Research Journal: 1, 16-20

<i>Melia azedarach</i> seed extracts were investigated in the laboratory against <i>Helicoverpa armigera</i>. The extracts exhibited significant antifeedant and growth disruption activity. The toxic symptoms of the poisoned larvae included reduction in weight gain and mortality of larvae and pupae, larval-pupal intermediates and malformed adults.
