Mosquitoes are the deadliest animals on earth and are the vectors of several neglected tropical diseases. Recently, essential oils have emerged as potential renewable, cost-effective, and environmentally benign alternatives to synthetic pesticides for control of mosquitoes. In this work, thirteen species of Piper were collected from different areas of central Vietnam. The essential oils were obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The essential oils were screened for mosquito larvicidal activity against Aedes aegypti . Four of the Piper essential oils showed outstanding larvicidal activity against Ae. aegypti , namely P. caninum , P. longum , P. montium , and P. mutabile , with LC 50 and LC 90 values less than 10 µg/mL. Multivariate analysis has correlated concentrations of β-caryophyllene, β-bisabolene, α-pinene, and β-pinene with mosquito larvicidal activity. |
