Objective To understand the potential of malaria by monitoring vectorial capacity of Anopheles sinensis, providing basis for early warning and prevention and control of malaria. Methods An investigation method for capacity of local vector transmission was used for quantitative calculation of An. sinences biting rate, human blood index, man-biting habit and expected life of infectivity, etc, and then the vector capacity and basic reproduction rate of An. sinensis was obtained according to the formula of Garrett-Jones (1964). Results The anopheles population declined year by year,the maximum density of An. sinensis was July, the host of An. sinensis was ubiquitous, the human blood index was 0.097 which was overall high, the peak season of basic reproduction rate was July, all higher than the critical value of 1.0. Conclusion There was a certain trend of malaria transmission, prevention and control task was still demanding, we need to increase mosquito control work of overwintering mosquitoes and the first generation mosquitoes of early spring.
