摘　　要：目的掌握云浮口岸地区白纹伊蚊孳生地类型和季节消长变化,观察诱蚊诱卵器在口岸地区的应用效果。方法白纹伊蚊孳生地调查,仔细检查环境中的各种积水容器,记录容器类型及是否有白纹伊蚊幼虫孳生;白纹伊蚊季节消长监测选择有代表性生境,采用人工小时法调查;采用诱蚊诱卵器法监测白纹伊蚊幼虫容器指数消长变化。结果白纹伊蚊孳生地调查中,查获积水容器569个,积水容器类型12种,平均容器指数13.36%,云浮口岸积水容器主要是旧轮胎,居民家中积水容器主要是废旧桶、瓦罐和蓄水池;白纹伊蚊高峰期从5月中旬持续至8月,时间较长;2011年6-11月共布放诱蚊诱卵器1620个,诱卵阳性容器数为151个,平均诱卵指数为9.41%,6-9月为白纹伊蚊诱卵指数高峰期。结论本次调查获得云浮口岸地区白纹伊蚊孳生、季节消长情况,为开展白纹伊蚊防治提供了科学依据,为诱蚊诱卵器在口岸应用提供了基础数据。Objective To investigate the breeding habitats and seasonal population fluctuation of Aedes albopictus at Yunfu port, Guangdong province, China and to observe the effect of mosq ovitraps applied at the port. Methods Various water containers were examined carefully to record the types of containers and whether Ae. albopictus larvae bred in the containers. The seasonal population fluctuation of Ae. albopictus was monitored by labor hour method in typical habitats. Mosq ovitraps were set to monitor the seasonal fluctuation in container index （CI） of Ae. albopictus larvae. Results There were 569 water containers detected, 76 of which contained Ae. albopictus larvae, with a mean CI of 13.36%. The water containers at Yunfu port were mainly waste tires, and those in households mainly included waste buckets, pots, and reservoirs. The population density of Ae. albopictus peaked from mid May to August. A total of 1620 mosq ovitraps were set from June to November in 2011, and oviposition was found in 151 of them, with a mean oviposition index （OI） of 9.41%. The OI peaked from June to September. Conclusion The breeding habitats and seasonal population fluctuation of Ae. albopictus at Yunfu port are acquired in the study. This information provides a scientific basis for Ae. albopictus control and essential data for setting of mosq ovitraps at the port.
