“…E. Vitella. For rearing and bioassay, modified Klein medium was used, replacing alfalfa meal with bhendi [Abelmoschus esculentus (L) Moench] seed powder (8). The diet contained 700 mL of sterile water, 15 g of agar, 30 g of yeast, 100 g of bhendi seed meal, 2 g of sorbic acid, 2 g of choline chloride, 4 g of ascorbic acid, 2.5 g of p-hydroxybenzoic acid methyl ester, 7 g of Wesson's salt mixture, 2 mL of vitamins (ABDEC), 2.5 mL of formaldehyde, and 0.1 unit of streptomycin.…”

Antifeedant and growth inhibitory effects of various neo-clerodane diterpenoids having a furofuran moiety, isolated from Clerodendron spp., were studied using Earias vitella and Spodoptera litura. The compounds clerodendrin B, 3-epicaryoptin, 15-hydroxyepicaryoptin, and clerodin were effective antifeedants at 10 microg/cm(3) (30 microg/g) of diet against E. vitella and at 10 microg/cm(2) of leaf against S. litura. All of the tested compounds, namely, clerodendrin B, 3-epicaryoptin, clerodendrin C, 15-hydroxyepicaryoptin, clerodendrin B acetate, and clerodin, showed good insect growth inhibitory activity even at lower concentrations.

The effect of 23 secondary plant compounds including a series of steroidal aglycones and glycosides, on larval growth and pupation of Earias insulana (Boisd.) was investigated. Larvae did not develop when fed on artificial diets containing 0.2% solamargine, solasonine, tomatine, digitonin, saponin, nomilin, lawsone or coumarin. Some growth‐retarding activity was found with diets containing 0.2% ajmalicine, capsaicin, quercetin, glycyrrhizin and glycerrhetic acid. The eight compounds highly active at 0.2% were also bioassayed at 0.1, 0.05 and 0.01%: larvae did not pupate when fed on diets containing 0.1% solasonine, tomatine or nomilin, whereas solamargine and coumarin were active even at 0.05%. Preliminary structure‐activity relationships were evaluated for the active steroidal glycosides. Zusammenfassung Larvale Wachstumshemmung des ägyptischen Baumwollkapselwurms, Earias insulana, durch einige Steroide sekundäre Pflanzeninhaltstoffe Es wurde die Wirkung von 23, einem künstlichen Nährmedium einverleibten, sekundären Pflanzeninhaltstoffen, unter ihnen eine Reihe steroider Aglucone und Glycoside, auf das Larvenwachstum und die Verpuppung von Earias insulana untersucht. Larven entwickelten sich nicht in mit 0.2% Solamargin, Solasonin, Tomatin, Digitonin, Saponin, Nomilin, Lawsone und Coumarin versetzten Nährmedien. Auf Medien, die 0.2% Ajmalicin, Capsaicin, Quercetin, Glycyrrhizin and Glycyrrhetinsäure enhielten, war das Larvenwachstum verzögert. Die 8 bei 0.2% hoch wirksamen‐Substanzen wurden auch bei 0.1, 0.05 und 0.01% getestet. Die Larven verpupten sich nicht auf 0.1% Solasonin, Tomatin und Nomilin und auf 0.05% Solamargin und Coumarin. Vorläufige Struktur‐Wirksamkeit‐Beziehungen wurden für die aktiven Steroiden Glycoside vorgeschlagen.
