Data collected from a longitudinal survey carried out over 2 years on four farms in western France were used to assess the incidence and infestation of Ixodes ricinus on rodents. Once a month, on each farm, 25 Sherman live traps were set in hedges bordering selected pastures. A total of 799 micromammals were examined, including Apodemus sylvaticus, Clethrionomys glareolus, Microtus agrestis, Microtus arvalis, and Crocidura spp. Larvae and nymphs of I. ricinus were found. Small numbers of Ixodes (Exopalpiger) trianguliceps were also recovered from each farm. The mean infestation rate of the I. ricinus larvae (1.6-5.9) among all animals examined varied between farms Most animals were infested by only a single tick, but one M. agrestis harboured 43 I. ricinus larvae. Larvae or nymphs were found throughout the year, with peaks from March to October.
从法国西部四个农场进行的为期两年的纵向调查中收集的数据，用于评估蓖麻硬蜱在啮齿动物上的发病率和感染情况。每个月，在每个农场的选定牧场边界的树篱中设置25个谢尔曼活饵诱捕器。总共检查了799只小型哺乳动物，包括林姬鼠、黄喉姬鼠、田鼠、草原田鼠和麝鼩属。发现了蓖麻硬蜱的幼虫和若虫。每个农场还发现了少量的三角硬蜱（外须硬蜱）。在所有检查的动物中，蓖麻硬蜱幼虫的平均感染率（1.6 - 5.9）因农场而异。大多数动物只被一只蜱虫感染，但一只草原田鼠身上有43只蓖麻硬蜱幼虫。全年都发现有幼虫或若虫，3月至10月为高峰期。
