บทคัดย่อ (EN): Aedes aegypti, the yellow fever mosquito, is a mosquito that can spread dengue fever and Zika fever. Dengue fever is caused by one of the four closely related dengue viruses (DENV) namely DENV1, DENV2, DENV3, and DENV4. Zika fever is an infectious disease caused by the Zika virus (ZIKV). In Thailand, the first dengue epidemic was reported in 1958, whereas Zika fever was first reported in early 2013. Until now, the diseases have become major public health problems. An intensive and long-term use of insecticides to control the mosquitoes results in the development of resistance mechanisms. Previous studies reported insecticide resistance in Ae. aegypti across Thailand. It might cause ineffective prevention and control of dengue fever and Zika fever. This study aimed to evaluate Le-mos aerosol spray against insecticide-resistant Ae. aegypti mosquitoes in six dengue-risk areas in Thailand. Six study areas located in Phitsanulok, Chumphon, Chanthaburi, Kanchanaburi, Nakhon Ratchasima and Nakhon Pathom were chosen for the collection of Ae. aegypti mosquitoes based on the report of insecticide resistance in Ae. aegypti and dengue-risk areas. The F1 progeny females from field mosquito populations were exposed to 8 individual insecticides: 0.8% malathion, 0.1% propoxur, 0.08% alpha-cypermethrin, 0.09% bifenthrin, 0.05% deltamethrin, 0.22% cypermethrin, 0.05% lambda-cyhalothrin and 0.75% permethrin by WHO susceptibility test for the confirmation of insecticide-resistant status as reported previously. Le-mos aerosol spray was formulated with 0.54% w/w of pyrethroid and 2.482% w/w mixed natural compounds of Citral, Citronellal, Citronellol, Geraniol and Linalool as active ingredients. The aerosol was sprayed approximately 5 gram indoor in 15-30% of total households per study area. The knockdown mosquitoes were kept in the paper cups with net cover. The mortality rate of mosquitoes was determined at 24 hours. The WHO susceptibility test confirmed that the Ae. aegypti mosquitoes in six dengue-risk areas were resistant to the insecticides with the mortality rate of less than 90% according to WHO criteria. The results showed that spraying the Le-mos aerosol indoor provided a 100% mortality rate of the insecticide-resistant mosquitoes in all six dengue-risk areas. The Le-mos aerosol spray developed was effective against the insecticide-resistant Ae. aegypti mosquitoes in all six dengue-risk areas with a 100% mortality rate. Further research is needed to develop a commercial anti-insecticide-resistant insect aerosol spray product with international standards of quality.
