This research aimed to develop a fipronil aerosol spray against pyrethroid-resistant Ae. aegypti mosquitoes from 6 dengue risk areas in 3 provinces; Chiang Mai, Tak, and Phitsanulok. Filial 1 hybrid female mosquitoes were tested with individual 5 pyrethroid insecticides, and fipronil at discriminating concentrations for susceptibility status by the World Health Organization procedure. The aerosol spray was developed and evaluated against the Ae. aegypti mosquitoes in Peet Grady Chamber. The result showed that the mosquitoes from 6 dengue high risk areas were resistant to all 5 pyrethroids with mean mortality rates of 2.0±2.3% – 80.0±3.3%. However, they were completely susceptible to fipronil with a 100% mortality rate. The mortality rates of mosquitoes were statistically significantly different among the insecticides (p<0.05). The aerosol spray containing 0.14% fipronil as an active ingredient provided a 100% mortality rate of pyrethroid-resistant Ae. aegypti from 6 dengue risk areas in 3 provinces. The knowledge obtained from this study will be used to develop an aerosol spray product against insecticide-resistant mosquito vectors to prevent mosquitoes-borne diseases.
