Abstract
The present study evaluates the efficacy of methanolic plant extracts of Shorea robusta and Oroxylum indicum against the pulse beetle Callosobruchus chinensis (L.). Various phytoactive compounds like alkaloid, terpenoid, flavonoids, saponins, phytosterols, glycoside, phenols and tannins were found in them. The plant extract of S. robuta shows 90% repellency followed by 81.5% with O. indicum at 12%. It was observed that S. robusta shows a potent effect in controlling C. chinensis with 78.30% mortality at 12% followed by O. indicum with 68.30% mortality at 12% concentration.
