[Louse infestation of the red marmot, Marmota caudata, during its active period].
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.
