An estimated 50 million people are infected with Dengue Fever every year and 2.5 billion people live in endemic DHF countries, including Indonesia. Kupang City is endemic for dengue and has the highest Incidence Rate in NTT. This means that the DHF prevention and control program in Kupang City has not been effective. The use of long-term insecticides without regard to proper dosage and on target can cause mosquito resistance to insecticides so that the density of mosquitoes and dengue cases can remain high even though larvae have been controlled by temefos. Aim. This study aims to determine the vulnerability status of Aedes sp larvae to temefos in Kupang City. Method. This descriptive observational study was conducted in the dry and rainy season in Kupang City. The sample is Aedes sp larvae in DHF cases and not DHF cases' houses that live around the dengue sufferers with 100 meters radius. Each village was taken 20 houses by cluster sampling for larval sampling. The larval observation was carried out at 30 minutes, 1 hour, 2 hours, 4 hours, 8 hours, and 24 hours exposure to temefos. Results. In the dry season and rainy season, it was found that larvae in all locations were still susceptible to temefos, with 98-100% mortality of larvae. The mortality for larval control in the rainy and dry season was 0%. Conclusion. The susceptibility status of Aedes sp larvae to temefos in Kupang City is still vulnerable. However, communication, information, and education on how to administer temefos in accordance with the correct dosage and method of use must still be carried out so that resistance or tolerance of larvae to temefos can be prevented.
