Lethal and sublethal effects of triterpenes from Junellia aspera (Verbenaceae) on the grain storage insect Tribolium castaneum (Coleoptera: Tenebrionidae)

, : Lethal and sublethal effects of triterpenes from Junellia aspera (Verbenaceae) on the grain storage insect Tribolium castaneum (Coleoptera: Tenebrionidae). Revista de la Sociedad Entomologica Argentina. July; 641-2: 45-51

Duration of the pupal stage, toxic activity and nutritional indices induced by oleanolic acid (I), maslinic acid (II), and daucosterol (III) isolated from the native plant Junellia aspera and chemical derivatives, were determinated on larvae, and adults of Tribolium castaneum (Herbst). The current study shows that these triterpenes acts as acute toxic compounds when were applied topically and/or incorporated into the food of the red flour beetle. Nevertheless, no activity related with the nutritional status of this insect was produced.
