2213 lice of Neohaematopinus palaearctcus Ols. were collected from 152 of 865 examined specimens of Marmota caudata Geoffr. from different vertical zones of Tadjikistan. The long-tailed marmot is characterized by a moderate or poor infestation with lice. In the subalpine zone, where the number and density of these animals in rather high, the infestation rate is greater than that in the brushwood zone. In spring after hibernation the infestation of M. caudata is very low. Within the reporoduction period the infestation with lice increases, the latter begin to reproduce intensively. During the preparation for hibernation the infestation rate falls due to a less intensive reproduction of lice. There are no distinct differences in the infestation rate of long-tailed marmots belonging to different age groups since there are constant contacts between the individuals of the colony. Only reproducing females live together with brood by themselves, differ in moulting periods and in a greater intensity of invasion during reproduction.
从塔吉克斯坦不同垂直地带的865只长尾旱獭（Marmota caudata Geoffr.）检查标本中的152只身上采集到2213只古北新血蚤（Neohaematopinus palaearctcus Ols.）。长尾旱獭的特点是跳蚤感染程度中等或较低。在亚高山地带，这些动物的数量和密度相当高，感染率高于灌木丛地带。冬眠后的春季，长尾旱獭的感染率非常低。在繁殖期内，跳蚤感染增加，跳蚤开始大量繁殖。在准备冬眠期间，由于跳蚤繁殖强度降低，感染率下降。属于不同年龄组的长尾旱獭在感染率上没有明显差异，因为群体中的个体之间有持续接触。只有繁殖期的雌性会独自与幼崽生活在一起，它们在换毛期以及繁殖期间的感染强度更大。
