Background. The cause of dengue fevers endemicity is vector larvae density, with Aedes aegypti as the prime vector. Bandung municipality is a high dengue fever endemic area. Hence, studying the habitat characteristics of the Aedes mosquito is essential to controlling the populations of mosquitos. Purpose. This study aimed to identify the aedes larvae breeding sites and the relationship between the breeding risk index, hygiene risk index, maya index, and the existence of larvae with the incidence of dengue fever. Method. The design used in this research was a cross-sectional survey. The sampling technique used simple random sampling. The quantity of the sample was 544 directly observed houses. Results. The entomological parameters obtained were house index (23.89%), container index (7.81%), Breteau index (50.73%), and larva free number (76.10%). The breeding risk index, hygiene risk index, and maya index are in the low category. The chi-square test conveyed that the breeding risk index, maya index, and the existence of larvae were significantly associated with the incidence of dengue fever. Conclusion. The entomological index may influence the high incidence of dengue fever. These findings and results may help the authorities to improve mosquito nest eradication in attempts to prevent dengue transmission.
