河漫滩和河流、湖泊和池塘的沼泽地等环境是水生昆虫适应静水条件的重要栖息地。此外，为农业人工建造的池塘和稻田也是依赖水的野生动物的重要替代栖息地。在这项研究中，我们集中在池塘中的水生昆虫在松本盆地，位于日本的中心。虽然这是一个城市化的地区，但适应洪泛平原的水生动物以相对较高的密度栖息在日本。我们对该地区33个池塘的环境进行了多方面的评价，并对栖息在池塘中的水生昆虫区系进行了调查。在这项研究中，我们进行了定量采样，重点是两个昆虫目适应大规模的静水环境（即，在松本盆地分别观察到3科5种和5科16种。在这些物种中，包括8种濒危物种。此外，我们进行了遗传结构分析的巨大水错误，Appasus的，高密度栖息在这些池塘，并进行了比较评估，这些池塘之间的遗传多样性。共采集530份A.对线粒体COI区进行遗传分析，共观察到26种单倍型。池塘之间的遗传多样性程度清楚地表明。此外，还根据其周围环境因子探讨了大水蝽越冬的可能性，并综合讨论了大水蝽在该区域的“源-汇”关系。因此，这是一个全面的研究，重点放在相关的环境因素，多样化的社区结构，他们的人口结构，他们的遗传结构在一个精细的尺度。
Environments such as floodplains and the marshlands of rivers, lakes and ponds, are important habitats for aquatic insects adapted to lentic water conditions. In addition, ponds and paddy fields artificially created for agriculture are also important alternative habitats for lotic water-dependent wildlife. In this study, we focused on aquatic insects in ponds in the Matsumoto Basin, located in the center of Japan. Although this is an urbanized area, aquatic animals adapted to floodplains inhabit it at a relatively high density for Japan. We conducted a multifaceted evaluation of the environments of the 33 ponds in this region and conducted a survey of the aquatic insect fauna inhabiting them. In this study, we conducted quantitative sampling, focusing on two insect orders adapted to large-scale lentic water environments (i.e., Heteroptera and Coleoptera), and observed five species of three families and 16 species of five families from the Matsumoto Basin, respectively. Within these species, eight endangered species were included. Furthermore, we carried out a genetic structure analysis for the giant water bug, Appasus japonicus, inhabiting these ponds in high density, and conducted a comparative evaluation of their genetic diversity between these ponds. A total of 530 specimens of A. japonicus were genetically analyzed for the mitochondrial DNA COI region, and 26 haplotypes were observed. The degree of genetic diversity between the ponds was clearly demonstrated. In addition, we discussed the wintering possibilities for the giant water bugs based on their corresponding surrounding environmental factors, and comprehensively discussed their “source−sink” relationships in this region. Therefore, this is a comprehensive study focused on the relevant environmental factors, diversification of their community structures, their population structures, and their genetic structure at a fine scale.
