Abstract
Toxic effect of plant leaf extract of Canavalia virosa on the feeding budget of Pericallia ricini was studied, using different concentrations of leaf alkaloid viz. 100, 200, 300, 400, 500, 1000, 1500 and 2000 ppm. Leaf extract concentration from 100 to 2000 ppm showed a significant negative correlation. An extended larval and pupal growth were observed at the highest dose of leaf extract (2000 ppm). Concentrated leaf alkaloid drastically affected feeding and organic constituents of the test insect P. ricini.
