Effective suppression of container-inhabiting Asian Tiger [Aedes albopictus (Skuse)] (Diptera: Culicidae) and yellow fever [Aedes aegypti (L.)] (Diptera: Culicidae) mosquitoes presents one of the most intractable problems for modern mosquito control. Traditional tools often fail to control populations of these mosquito species, and are prohibitively expensive or have negative environmental impacts. Novel approaches and tools are urgently needed for integrated container-inhabiting mosquito management programs. One of the most promising techniques is autodissemination. We present the results of a long-term large-scale study conducted in a temperate urbanized environment representing typical Ae. albopictus habitats. Three treatment sites with autodissemination stations and three nearby reference sites were monitored for eggs, immature, and adult mosquitoes over a period of 3 yr from 2014 to 2016. Elevated larval and pupal mortality of 12-19% on average was the most notable outcome in sentinel cups of the treatment sites. The number of eggs in the treatment sites was significantly reduced in 2014, but not in 2015 or 2016. Adult populations remained similar in treatment and reference sites throughout the study. The impact of autodissemination on mosquito populations was lower than reported by previous investigations. Technical and logistical problems associated with wider coverage and working in multiple urban neighborhoods contributed to reduced efficacy. Incorporating autodissemination with routine mosquito control operations and commercializing this methodology for general public use will require further research on combining this tool with other novel or conventional technologies.
有效抑制容器滋生的亚洲虎蚊（白纹伊蚊）（双翅目：蚊科）和黄热病蚊（埃及伊蚊）（双翅目：蚊科）是现代蚊虫控制面临的最棘手问题之一。传统工具往往无法控制这些蚊种的数量，而且成本过高或对环境有负面影响。迫切需要新的方法和工具来实施综合容器滋生蚊管理计划。其中最有前途的技术之一是自动传播。我们展示了在温带城市化环境中进行的一项长期大规模研究的结果，该环境代表了白纹伊蚊的典型栖息地。在 2014 年至 2016 年期间，我们对三个设有自动传播站的处理地点和三个附近的对照地点进行了为期 3 年的卵、幼虫和成虫蚊虫监测。在处理地点的哨兵杯中，幼虫和蛹的死亡率平均升高了 12-19%，这是最显著的结果。2014 年处理地点的卵数量显著减少，但 2015 年和 2016 年没有减少。整个研究期间，处理地点和对照地点的成虫种群数量相似。自动传播对蚊虫种群的影响低于以前调查的报道。更广泛的覆盖范围和在多个城市社区工作的技术和后勤问题导致了效率降低。将自动传播与常规蚊虫控制作业相结合，并将这种方法商业化供公众使用，需要进一步研究将这种工具与其他新的或传统技术相结合。
