The objective of the study was to evaluate the chemical profile and larvicidal activity of essential oil (EO) and nanoemulsions oil-em-water (O/A) of the leaves of Eucalyptus globulus Labil and Ocimum africanum Lour. A significant total phenolic count correlated to an efficient antioxidant activity was found. The essential oils did not show high toxicity in our toxicity tests. We observed larvicidal action of the EO of E. globulus and O. africanum...
