广州地区白纹伊蚊自然种群幼虫的分布特征

目的掌握自然种群白纹伊蚊幼虫在广州地区的孳生分布特点,为白纹伊蚊自然种群变动的监测与控制提供依据。方法对广州市2004、2005年不同场所孳生白纹伊蚊的积水容器进行全年监测及调查,对获取的与分布特征有关的数据进行统计分析。结果在广州地区,孳生白纹伊蚊幼虫的各种积水容器在不同场所的分布比例有很大差异,其中居民区的水生植物容器所占比例最大,为44.68%;各种环境场所均具有其不同的孳生白纹伊蚊积水容器种类分布特征。结论广州地区白纹伊蚊自然种群幼虫的分布特征因不同环境而异。摸清白纹伊蚊幼虫在不同场所的分布特征及各类孳生白纹伊蚊积水容器在不同场所的重要性,对有效监测与控制白纹伊蚊种群具有指导性意义。

The larva distribution characteristics of Aedes albopictus population in Guangzhou

Objective To realize the distribution characteristics of Aedes albopictus larva in Guangzhou,which is the basic for the surveillance and control of natural population of Ae.albopictus.Methods Water containers or receptacles where Aedes larva breeded in different environments were detected in 2004 and 2005 in Guangzhou.The data that related to the larva distribution characteristics were analyzed by statistics.Results The kinds of water receptacles' distribution proportion in different environments varied remarkably.The proportion of plant containers was the highest in residential area,was 44.68%.The distribution features of water containers breeding Aedes mosquitoes varied in different environments in Guangzhou.Conclusion The larva distribution characteristics of Ae.albopictus varied remarkably in different environments.The understanding for the distribution characteristics and proportions of different kinds of water container breeding Ae.mosquitoes in different environments is meaningful for efficient surveillance and control of Ae.albopictus population.
