Abstract

Activity of triterpenoids from Cedrela fissilis (Meliaceae) against Spodoptera frugiperda.

Abstract

The activity of five triterpenoids, oleanolic acid, oleanonic acid, hispidol A, piscidinol A and odoratol, isolated from stems and fruits of Cedrela fissilis (Meliaceae), was evaluated against the fall armyworm Spodoptera frugiperda. Toosendanin was used as a positive control. A prolongation of the larval phase was observed for insects treated with oleanolic acid, oleanonic acid and odoratol at 1.0, 10.0 and 50.0 mg/kg when compared with the control. All the tested compounds reduced pupal weight. The best results were obtained with odoratol that showed 90% of larval mortality. Correlation between insecticidal activity and chemical structure has been discussed.
