Larvae of N. sympatrica were found on 64 individuals of rodents belonging to 8 species (Table 2). The grey hamster and the Tien Shan vole had larvae around the anus only, while the Kirghizian vole and the Turkestani rat had larvae inside the cochlea. The parasites infested five regions of the body of the silvery high-mountain vole. They obviously preferred to feed on the inside of the cochlea (70.51% of the feeding larvae) and on the edge of the ear (21.3%) on this rodent. 30.98% of the larvae N. sympatrica collected from the silvery highmountain vole were found in combings. The larvae infested six regions of the skin of common vole, and preferred to feed on the edge of the ear (48.21%) and on the belly (19.64%). The great majority of all mites collected from the common vole (81.46%) were found in combings. The most places of infestation (7) were registered in the wood mouse; the mites preferred to feed around the anus (44.21%) and on the belly (26.32%). Less than half of all collected mites (43.45%) appeared in combings. The greatest quantity of feeding mites was found in the silvery high-mountain vole (69.02%) and in the wood mouse (56.55%). Distribution of N. sympatrica on the various areas of the skin of the three main hosts is shown in Table 3. Table 3.

A total of 267 larvae was collected from 22 animals of 5 species in the Alexander Mountains, 36.70% of them were fed. Preference was given to the inside of the cochlea (47.96%). 2286 specimens were removed from 32 rodents of 5 species captured in the Kungey Ala-Too, 62.38% of them were stuck. The larvae also preferred to feed on the inside of an ear (62.90%). 109 larvae of N. sympatrica were collected from 10 animals of 3 species in the Sary-Chelek Reserve, 5 of them were in combings only, the others (95.41%) were found stuck in the inside of the cochlea.
