了解蚊子的传播对媒介传播疾病的控制和预防策略以及了解种群结构和病原体传播至关重要。我们在波多黎各和泰国进行了11年（1991-2002）的21次放归-再捕获实验，确定了埃及伊蚊的飞行范围和传播模式。按放生地点、性别、年龄、季节和村庄进行扩散比较。在所有实验中，大多数蚊子是从他们的放养所或邻近的房屋收集的。很少发现村间移动，少数蚊子从一个泰国村庄移动到另一个村庄最多512米。雄性和雌性的平均扩散距离相似，雌性在室内和室外释放。Ae的运动。埃及伊蚊的分布不受季节和年龄的影响，但因村庄而异。结果表明：成年伊蚊；埃及伊蚊的传播距离相对较短。这表明人而不是蚊子是登革热病毒在社区内和社区间传播的主要方式。
Knowledge of mosquito dispersal is critical for vector-borne disease control and prevention strategies and for understanding population structure and pathogen dissemination. We determined Aedes aegypti flight range and dispersal patterns from 21 mark-release-recapture experiments conducted over 11 years (1991-2002) in Puerto Rico and Thailand. Dispersal was compared by release location, sex, age, season, and village. For all experiments, the majority of mosquitoes were collected from their release house or adjacent house. Inter-village movement was detected rarely, with a few mosquitoes moving a maximum of 512 meters from one Thai village to the next. Average dispersal distances were similar for males and females and females released indoors versus outdoors. The movement of Ae. aegypti was not influenced by season or age, but differed by village. Results demonstrate that adult Ae. aegypti disperse relatively short distances. suggesting that people rather than mosquitoes are the primary mode of dengue virus dissemination within and among communities.
