Abstract: Objective To survey Aedes albopictus larval population density and seasonal distribution, and provide basic vector biology for the prevention and control of vector-borne diseases in Henan province. Methods Breteau index(BI), container index(CI) and mosq-ovitrap index(MOI) were used in urban and rural community during May to October 2016 and compared the seasonal changes of these indexes in 17 monitoring sites. Results The provincial average BI was 23.51, peak BI was 32.40 in August; average CI was 15.30%, peak CI was 20.26% in September; average MOI was 7.86, peak MOI was 25.77 in August. BI and CI peaks were unimodal, MOI peak was bimodal. Conclusion Aedes albopictus was widely distributed in urban and rural communities with high abundance. It is recommended to carry out urban and rural environmental sanitation to reduce the breeding of Aedes mosquitoes, and avoid outbreaks of mosquito-borne diseases such as dengue fever, Zika, or yellow fever.
