Abstract: Aedes aegypti mosquito is a vector of dengue which is still a public health problem in Indonesia. Temefos is the most common larvae used to control Ae. Aegypti. The study aimed to determine the lethal concentration (LC₅₀, ₉₀, and ₉₈) and lethal time (LT₅₀, ₉₀, and ₉₈) so that the temephos concentration and time can be known in controlling the Ae. Aegypti larvae. This research method is an experiment according to the WHO standard on Ae. aegypti larvae as many as 25 individuals each treatment using temephos insecticide with a concentration of 0.003 mg/L, 0.006 mg/L, 0.012 mg/L and 0.025 mg/L. The results of the study is LC_50, LC₉₀ and LC₉₈ respectively were 0.008 mg/L; 0.015 mg/L and 0.018 mg/L. Furthermore, LT_50, LT₉₀ and LT₉₈ respectively were 34.808 hours; 57.197 hours and 70.688 hours.
