N2 - The larvicidal activity of commercial bark saponin extract (Sigma) from Quillaja saponaria was studied on 3rd-4th instar larvae of Aedes aegypti and Culex pipiens (vectors for dengue fever and Western Nile virus, respectively). The larvae were exposed to serial concentrations (1000, 800, 500, 300, 100, 10, 1, 0.1 and 0.01 mg/l) of the extract for 1, 3, 5, 7 and 11 days. The results indicate that commercial bark saponin is toxic, causing 100% larval mortality in A. aegypti and C. pipiens after 1 and 5 days at a dosage of 800 and 1000 mg/l, respectively. Interestingly, while bark saponins had a toxic effect on larvae there was no effect on egg hatchability in either species. The results obtained suggest that, in addition to their known activities, saponins can also serve as natural larvicidal compounds.
