Result:The average house index 56.5 and countainer index 54.5 and the Breteau index 175.5 . The sucking rate was 42.3 per hour and man befor the control.The result in the reinvestigation shown that the house index was reduced to 2.4 and countainer index 11.5 and the Breteau index 4.0 respectively. The sucking rate was zero after the control. Conclusions: The density of Aedes albopictus was reduced obviously. The epidemic dengue was abstructed rapidly and the case not found from 12 October.
