Hyperparasitism of ectoparasitic water mite larvae on mosquitoes is still a neglected relationship and was investigated only in a few studies. We analysed 2313 female mosquitoes from six different sampling localities with regard to their degree of parasitism with water mite larvae. In total, we found 38 mosquito individuals parasitized by 93 water mite larvae, ranging from 1 to 12 larvae per mosquito. Water mite larvae detected are members of the two species Parathyas cf. barbigera (n = 92) and Arrenurus cf. globator (n = 1). Out of the analysed mosquitoes, individuals out of the species Aedes vexans, Anopheles claviger, Ochlerotatus communis, the Ochlerotatus cantans/annulipes group, Ochlerotatus cataphylla and Ochlerotatus sticticus were tested to be parasitized by water mite larvae. The highest prevalence was found within the species Oc. cataphylla (28.6 %) and Oc. cantans/annulipes (21.7 %). No water mite larvae were found, e.g. on individuals of Aedes cinereus, Coquillettidia richiardii, the Culex pipiens/torrentium group, Ochlerotatus caspius, Ochlerotatus dorsalis or Ochlerotatus punctor. All of the attachment sites were located between the neck and abdomen with the ventral thorax site being the most frequent one.
外寄生性水螨幼虫对蚊子的重寄生现象仍是一种被忽视的关系，仅在少数研究中被调查过。我们分析了来自六个不同采样地点的2313只雌蚊，以研究它们被水螨幼虫寄生的程度。总共，我们发现38只蚊子个体被93只水螨幼虫寄生，每只蚊子身上的幼虫数量从1只到12只不等。检测到的水螨幼虫属于Parathyas cf. barbigera（n = 92）和Arrenurus cf. globator（n = 1）这两个物种。在分析的蚊子中，伊蚊、棒角按蚊、普通伊蚊、刺扰伊蚊/环跗伊蚊组、叶状伊蚊和点刻伊蚊的个体被检测到被水螨幼虫寄生。叶状伊蚊（28.6%）和刺扰伊蚊/环跗伊蚊（21.7%）的寄生率最高。例如，在灰黑伊蚊、里氏库蚊、尖音库蚊/溪流库蚊组、里海伊蚊、背点伊蚊或点刻伊蚊的个体上未发现水螨幼虫。所有附着部位都位于颈部和腹部之间，其中胸部腹侧部位最为常见。
