Abstract

Objectives: To test the mosquito repellent and insecticide effects of Geranium essential oil (Pelargonium graveolens) on Aedes aegypti (Ae. aegypti) and Aedes albopictus (Ae. albopictus) mosquitoes. Methods: A descriptive, experimental study in the laboratory, using the World Health Organization's mosquito repellent testing techniques to determine the mosquito repellent dose, protection time, and mosquito repellent dose. Results: Geranium essential oil repelled two species of mosquitoes at a dose of 0.1 µL/cm2 applied to the skin. Geranium essential oil diluted in coconut oil repelled 244 minutes against Ae. aegypti mosquitoes and 178 minutes against Ae. albopictus mosquitoes. All Ae. aegypti and Ae. albopictus mosquitoes fell and died after exposure to an essential oil dose of 0.11 µL/cm2. Conclusion: Geranium essential oil showed repellent and insecticidal activities against Aedes mosquitoes at a dose of 0.11 µL/cm2, minimum protective time of 178 minutes.
