Abstract: Objective To study the effect of integrated control aimed at mosquito larvae in the urban environment. Methods The health education to the urban residents and treatment of mosquito breeding sites were conducted in the test zone of Nanjing city. The densities of Culex and Aedes mosquitoes were monitored by light traps and ovitraps. Results The population related index(PRI) of Culex and Aedes mosquitoes were 0.123 and 0.132 respectively, and decreased by 87.7% and 86.8% respectively. The mean of mosquito population was 1.2 for one lamp and the decreased rate of positive breeding sites was 95.5%. Conclusion There is good effect in the urban integrated control aimed at mosquito larvae. It is valuable and practicable to adopt the strategy of the integrated mosquito control in the city. For example, health education is conducted to all people by government, their own mosquito breeding sites are cleared away by the urban residents themselves, the mosquito breeding sites in the public places are cleaned up and the larvicide is used in permanent breeding sites by pest control operators(PCO).
