- We evaluated ylang ylang oil and lemongrass oil that diluted in three diluents; coconut oil, soybean oil and olive oil.
- These essential oils were tested against two mosquito vectors, Aedes aegypti (L.) and Culex quinquefasciatus.
- Ylang ylang oil in coconut oil exhibited excellent activity with 98.9% protection from bites of A. aegypti for 88.7 min.
- Lemongrass oil in olive oil showed excellent activity with 98.8% protection from bites of C. quinquefasciatus for 170.0 min.
