The relationships between water mite larvae parasitizing Coenagrion scitulum in core and edge populations were described. A total of 636 larvae of 7 water mite species were found on 143 C. scitulum adults (82 females and 61 males). C. scitulum was recorded for the first time as a host species for Arrenurus cuspidator, A. bruzelii, A. bicuspidator, A. tricuspidator, A. claviger and Hydryphantes octoporus. The degree of infestation by particular parasite species was typical for these species. In contrast, the parasites' preferences for host body parts were not typical, as they preferred abdominal segments 2-4, which in earlier studies had been avoided by water mite larvae. No differences were found in degree of infestation of Coenagrion scitulum individuals between core and edge populations, with the exception of Hydryphantes octoporus, which parasitized damselflies only in core populations.
描述了寄生在核心种群和边缘种群的细腹豆娘（Coenagrion scitulum）上的水螨幼虫之间的关系。在143只细腹豆娘成虫（82只雌虫和61只雄虫）上共发现了7种水螨的636只幼虫。细腹豆娘首次被记录为尖刺阿氏水螨（Arrenurus cuspidator）、布鲁泽阿氏水螨（A. bruzelii）、双齿阿氏水螨（A. bicuspidator）、三齿阿氏水螨（A. tricuspidator）、棒形阿氏水螨（A. claviger）和八孔水螨（Hydryphantes octoporus）的宿主物种。特定寄生虫物种的侵染程度对于这些物种来说是典型的。相比之下，寄生虫对宿主身体部位的偏好并不典型，因为它们更喜欢腹部第2 - 4节，而在早期研究中，水螨幼虫会避开这些部位。在核心种群和边缘种群的细腹豆娘个体的侵染程度上，除了八孔水螨仅在核心种群中寄生豆娘外，未发现差异。
