Abstract:
Eight steroids isolated from solanaceous plants (Physalis, Withania and Nicandra species) were investigated as to their antifeedant efficacy for L4 larvae of Epilachna 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), 4β-hydroxywithanolide E (II), 5β, 6β-epoxy-1β, 14α, 17β, 20α-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 of Spodoptera littoralis (Boisd.) (Lepidoptera) found in a previous study. © 1981 Springer Science + Business Media B.V.
