Abstract: Objective By investigating population density and breeding characters of Dengue vectors in Fuzhou Changle International Airport to prevent and control Dengue fever.Methods The species and breeding characters of vectors were investigated in September,2004,the density of the larva was calculated by Breteau index,thousand-person index and container index.While the biting rate index was used to calculate density of the adult.Results Aedes albopictus was the dominant species,the Airport waiting hall has 0.00 of thousand-person index and container index.In other airport regions such as the aviation repair plant,food-plant,the dormitories region,the restaurant,the goods-station Breteau index were 0.00,7.55,4.11,33.33,25.81 respectively,the Dahe village closest to the airport was 67.92.There were five kinds small container being main breeding place of Aedes albopictus,such as a large number old jars and crocks in Airport as well as in the village.The biting rate for Aedes albopictus/ were 0.33 and 6.22/h.m in the aviation food-plant and the Dahe village.Conclusion The density of Aedes albopictus in the Dahe village nearby airport was higher than other surveillant regions.It is important to administ the envionment near the airport to control the Dengue fever.
