description	Piper marginatum and Piper tuberculatum are species used by local indigenous, people who live especially in eastern Ecuador, for their insecticidal properties. This study aimed to determine the acaricidal and larvicidal activity of the essential oil of these species. The essential oils were obtained by hydrodistillation. The acaricidal activity was evaluated with the contact toxicity method against larvae of the tick Rhipicephalus microplus. Larvicidal activity was determined against Aedes aegypti mosquito larvae following WHO recommended guidelines. The essential oils of P. marginatum and P. tuberculatum showed an acaricidal potential with LC50 of 0.90 and 0.73 µL mL-1, respectively. In addition, excellent larvicidal activity was obtained with LC50 of 11.87 µL mL-1 (P. marginatum) and 8.42 µL mL-1 (P. tuberculatum) at 48 hours of evaluation. This is the first report of the acaricidal activity of P. marginatum and P. tuberculatum essential oils against Rhipicephalus microplus tick larvae. The results indicate that essential oils could be a natural alternative for the controlling these pests and would justify their ethnobotanical applications as a lice and tick repellent.

Piper marginatum y Piper tuberculatum son especies empleadas por indígenas locales, personas que habitan especialmente la zona Oriental de Ecuador, por sus propiedades insecticidas. Este estudio tuvo como objetivo determinar la actividad acaricida y larvicida del aceite esencial de estas especies. Los aceites esenciales se obtuvieron por hidrodestilación. La actividad acaricida se evaluó con el método de toxicidad por contacto frente a larvas de la garrapata Rhipicephalus microplus. La actividad larvicida se determinó frente a larvas del mosquito Aedes aegypti siguiendo los lineamientos recomendados por la OMS. Los aceites esenciales de P. marginatum y P. tuberculatum mostraron un potencial acaricida con CL50 de 0.90 y 0.73 µL mL-1, respectivamente. Además, se obtuvo una excelente actividad larvicida con CL50 de 11.87 µL mL-1 (P. marginatum) y 8.42 µL mL-1 (P. tuberculatum) a las 48 horas de evaluación. Este es el primer reporte de la actividad acaricida de los aceites esenciales de P. marginatum y P. tuberculatum frente a las larvas de la garrapata Rhipicephalus microplus. Los resultados indican que los aceites esenciales podrían ser una alternativa natural para el control de estas plagas y justificaría sus aplicaciones etnobotánicas como repelente de piojos y garrapatas.
