A detailed review is presented of half a century's research in Japan, Korea and the temperate zone of China on the overwintering of Culex tritaeniorhynchus, the main vector of Japanese encephalitis. The evidence indicates that in the temperate zone, two types of overwintering strategy can be distinguished in Cx. tritaeniorhynchus, ie survival by adults in situ in a dormant state, or migration by individuals which are in reproductive diapause. The authors contend that the former strategy is not very effective, and individuals which overwinter in this way do not constitute the main source of the next season's mosquito populations. On the contrary, new mosquito populations seem to be established by groups of adults which appear suddenly, early in the year, and which are probably windborne migrants from the south. It is concluded that further research into the mode of overwintering of Cx. tritaeniorhynchus should focus on the effective source of the populations which appear in temperate areas in early spring, and that efforts should be made to increase our understanding of the migration patterns of this species.
本文详细综述了日本、韩国及中国温带地区半个世纪以来对日本脑炎主要传播媒介三带喙库蚊越冬情况的研究。证据表明，在温带地区，三带喙库蚊可区分出两种越冬策略，即成虫以休眠状态就地存活，或处于生殖滞育的个体进行迁徙。作者认为前一种策略效果不佳，以这种方式越冬的个体并非下一季蚊虫种群的主要来源。相反，新的蚊虫种群似乎是由年初突然出现的成年群体建立的，这些群体可能是来自南方的随风迁徙者。得出的结论是，对三带喙库蚊越冬方式的进一步研究应聚焦于早春出现在温带地区的种群的有效来源，并应努力增进我们对该物种迁徙模式的了解。
