Abstract
The present studies were designed to assess the Effect of plant chemical Azadirachtin against pupae of Spodoptera litura. The result show that leaf extract of A.indica caused maximum pupal mortality of 84 percent when pupae were treated at 2% extract.At 0.1, 0.5, 1 and 1.5% concentrations percent mortality in pupae was reported as 25.33, 34.66, 46.66 and 62.65 respectively and  Seed extract of A.indica was observed to be more effective in comparison to leaf extract. Maximum mortality of 92 percent was recorded when pre-pupa were treated with 2% of seed extract. At 0.1, 0.5, 1.0 and 1.5% of extract, mortality caused was 30.66, 42, 49.33 and 76 percent respectively. Highest larvicidal and pupicidal activity was shown by seed extract of A.indica followed by leaf extracts of A.indica.

Key words:Azadirachtin, Seed extract, leaf extract, Pupae.
