Associations between species of Laelapidae (Mesostigmata: Dermanyssoidea) mites and small rodents have been studied insufficiently. The aim of this study was to investigate infestation patterns of small rodent species by laelapid mites at six locations in Lithuania. A total of 728 rodents were snap- and live-trapped in various locations during 2013–2016. Eight rodent species were identified, namely Apodemus flavicollis, Apodemus agrarius, Myodes glareolus, Micromys minutus, Mus musculus, Microtus oeconomus, Microtus arvalis and Microtus agrestis. A total of 343 (47.1%) rodents were found to be infested with up to eight species of parasitic mites from the Laelapidae family (n = 1363): Laelaps agilis, Laelaps hilaris, Hyperlaelaps microti, Haemogamasus nidi, Haemogamasus hirsutus, Eulaelaps stabularis, Hirstionyssus sunci and Myonyssus gigas. The dominant species of mite found on rodents was L. agilis (89.1%), found on 43.4% of all hosts. Abundance and mean intensity of infestation with mites varied among species of hosts and were highest for A. flavicollis. We document new geographical and host records for gamasid mites of eight rodent species in Lithuania.

立陶宛不同瓢虫（Mesostigmata：Dermanyssoidea）螨虫和小啮齿动物之间的联系。

尚未充分研究瓢虫科（Mesostigmata：Dermanyssoidea）和小型啮齿动物之间的关联。这项研究的目的是调查立陶宛6个地点的小白点螨对小型啮齿动物的侵染模式。2013-2016年期间，共有728只啮齿动物在不同地点被捕捉和活捉。八鼠种进行了鉴定，即黑线姬鼠flavicollis，黑线姬鼠，Myodes glareolus，巢鼠，小家鼠，根田鼠，田鼠arvalis和田鼠蛞蝓。总共发现343只（47.1％）啮齿动物被来自Laelapidae家族（n = 1363）的多达8种寄生螨侵扰：Laelaps agilis，Laelaps hilaris，Hyperlaelaps microti，Haemogamasus nidi，Haemogamasus hirsutus，Eulaelaps stabularis， Hirstionyssus sunci和Myonyssus gigas。在啮齿类动物中发现的螨虫的主要种类是吉利乳杆菌（89.1％），在所有寄主中占43.4％。寄主种类对螨的侵染程度和平均强度各不相同，黄曲霉最高。我们记录了立陶宛8种啮齿动物的Gamasid螨的新地理和宿主记录。
