Development of nano-emulsions based on Ayapana triplinervis essential oil for the control of Aedes aegypti larvae.

Ayapana triplinervis is a plant species used in traditional medicine and in mystical-religious rituals by traditional communities in the Amazon. The aim of this study are to develop a nano-emulsion containing essential oil from A. triplinervis morphotypes, to evaluate larvicidal activity against Aed...
