Abstract：Objective To understand the density and seasonal fluctuation of dengue vector,Aedes albopictus,in Neijiang City,and provide the scientific evidence for mosquito control.Methods On-site monitoring was conducted in the middle of each month from May to October.Aedes albopictus larvae densities were monitored by BI,CI and HI.Aedes albopictus adult densities were monitored by double mosquito net method.Results The densities of Aedes albopictus larvae showed unimodal type in Neijiang City in 2016,and the peak appeared in July (BI =27.5,CI =11.25,HI =22.50).The idle containers held the highest CI of 21.05.Aedes albopictus adults changed significantly with seasons with unimodal type,and the peak appeared in June.Biting index was 3.75 sucking per person for one hour.The highest density of Aedes albopictus adult happened in piled up waste tyre,with the biting index of 7.83 sucking per person for one hour.Conclusion Aedes albopictus population density was high in Neijiang City.It is necessary to strengthen the monitoring and environmental regulation,and carry out health education work.
