Formulation and Evaluation of Herbal Nanoemulsion for Mosquitocidal Activity Against Dengue Vector Aedes aegypti

The increasing resistance of Aedes aegypti to conventional insecticides has necessitated alternative vector control strategies. This study investigates the formulation and efficacy of a herbal nanoemulsion containing essential oils with mosquitocidal properties. The nanoemulsion was prepared using an ultrasonic emulsification method and characterized for particle size, zeta potential, and stability. Larvicidal and adulticidal bioassays were conducted to evaluate its effectiveness against Aedes aegypti. Results indicated significant mortality rates at low concentrations, demonstrating the potential of herbal nanoemulsions as an eco-friendly and sustainable mosquito control strategy. This study provides insights into the development of natural, nano-based solutions for dengue vector management.
