Abstract

Vector surveillance is pivotal for dengue prevalence. The oviposition ability, survival rate, and distribution of dengue vector species can indicate the population density and are components of mosquito survival strategies. The density of dengue vectors is influenced by altitude, population density, water sources, and vegetation characteristics in their breeding habitats. This study aims to determine the oviposition ability, survival rate, and distribution of dengue vectors in Bengkulu City. This study employed a quantitative method with a descriptive observational design. Data were obtained by collecting Aedes spp. eggs from 67 urban villages in Bengkulu City. The survival rate was determined through colonization, and the distribution of mosquito species was analyzed based on the mosquitoes resulting from colonization. Beringin Raya was identified as the urban village with the highest oviposition ability, while Kandang was identified as the lowest. The highest survival rate of dengue vectors was found in Jalan Gedang, while the lowest was found in Sumber Jaya, Muara Dua, Padang Jati, and Tengah Padang. Aedes aegypti dominated 36 urban villages, while Aedes albopictus dominated 26 urban villages. In conclusion, dengue vectors were distributed across all urban villages in Bengkulu City, with Aedes aegypti being the dominant species.
