Abstract: Objective To investigate the changes in the population density indices of Aedes albopictus and their influential factors in Ningbo city, China, and to provide a basis for the control of dengue vector. Methods The densities of Ae. albopictus larvae in different environments in Ningbo were monitored and investigated, and the relationship between the changes in densities and climate and environment were analyzed. Results The container index (CI), house index (HI), and Breteau index (BI) for Ae. albopictus in Ningbo were 9.26%, 8.88%, and 10.57, respectively, in 2011, and the total density of Ae. albopictus larvae reached the peak value in August. The density in the permanent container was significantly higher than that in the temporary container, with the maximum value in the pool and tank; the density in resident community was significantly higher than that in the park, construction site, and salvage station, with the minimum value in the school and hospital. Conclusion The population density of Ae. albopictus and its seasonal fluctuation were influenced by multiple factors.
