Dengue Hemorrhagic Fever is a major health problem in Indonesia. The existence of Aedes Aegypti mosquito is the main vector that causes Dengue Hemorrhagic Fever . The bionomics of the Aedes Aegypti mosquito is a risk factor for causing Dengue Hemorrhagic Fever (Mawardi and Busra, 2019). The incidence of Dengue Fever in the people of Enrekang Regency is influenced by the living habits of the Aedes Aegypti mosquito. Bionomic data of the Aedes Aegypti mosquito in the Enrekang Regency area is not yet available. In the Enrekang district, there were 166 cases of dengue fever in 2019, an increase of 209 cases in 2020, and a decrease in 2021 of 64 cases. Cases of Dengue Hemorrhagic Fever in Enrekang district are included among the 10 highest diseases. To determine the bionomic relationship (biting and resting behavior) of Aedes Aegypti mosquitoes with the incidence of Dengue Hemorrhagic Fever in the Enrekang district. The method in this research is analytic observational using a cross-sectional study approach. Analytical observational is research that tries to identify how health phenomena occur. Sampling was done by the total sampling method. The data was obtained directly from the Enrekang District health office. The results showed that there was no significant relationship between the biting behavior of Aedes Aegypti mosquitoes (p = 0.470), while the resting behavior of Aedes Aegypti mosquitoes had a significant relationship (p = 0.000) with the incidence of Dengue Hemorrhagic Fever in Enrekang District. The results of the study show that the habit of the Aedes Aegypti mosquito is a risk factor for Dengue Hemorrhagic Fever in the Enrekang district.
