Résumé

Eight steroids isolated from solanaceous plants (Physalis, Withania andNicandra species) were investigated as to their antifeedant efficacy for L4 larvae ofEpilachna varivestis Muls. (Coleoptera). Nicalbin A (VII) was a potent antifeedant, but at high concentrations it was also toxic to this insect. Other active compounds were withanolide E (I), 4?-hydroxywithanolide E (II), 5?, 6?-epoxy-1?, 14?, 17?, 20?-tetrahydroxywith-24-enolide (III), Nic-1 (nicandrenone, VI) and nicalbin B (VIII). These results were quite different from the spectrum of activity of the withanolides against larvae ofSpodoptera littoralis (Boisd.) (Lepidoptera) found in a previous study.
