Metabolite Content of Local Bitter White Lupin Seeds (Lupinus albus L.) and Acaricidal and Insecticidal Effects of its Seed Extract

This study investigated the acaricidal and insecticidal effect of local lupin (Lupinus albus L. Fabaceae) seed extract against Tetranychus urticae Koch (Acari: Tetranychidae), Callosobruchus maculatus F. (Coleoptera: Chrysomelidae), Plodia interpunctella (Hubner) (Lepidoptera: Pyralidae) metabolite content seeds. In tests for T. leaf-disk bioassay was employed. Contrarily, two μL were topically applied using a micro-applicator on C. P. interpunctella. assays interpunctella, concentrations 0.78, 1.56, 3.12, 6.25, 12.5, 25% (w/w) plant extracts used. Furthermore, 0.625, 1.25, 2.50, 5, 10% to maculatus. Mortality data collected 24, 48 72 hours after application. results, found be quite effective adults with LD50 7.26, 1.21 0.55% hours, respectively. Moreover, LC50 values 4.03, 3.15 2.73% same durations. showed low larvae seeds detected, which contained 686.99 mg GAE / 100 total phenol, 22.06 QE flavonoid, DPPH 26.04 TE g having antioxidant activity. The bitter taste stem is due their has toxic effect. conclusion, results indicated that high secondary metabolites also its had
