Coexistence of N. sympatrica with other species of chigger mites is considered by the example of three individuals of the silvery high-mountain vole captured in the Kyrchyn tract of the Kungey Ala-Tau (Table 4). The first individual (inventory No. 472) had 382 larvae of 5 species of 3 genera (Neotrombicula, Leptotrombidium and Shunsennia) in August. Four species of 2 genera were found in a cochlea. Of the species 3 belonged to the genus Neotrombicula, but N. sympatrica amounted to 83.62% in this collecting. 301 larvae of 7 species of 3 genera were taken from the second silvery high-mountain vole (Inventory No. 541) in September, and 4 species belonged to the genus Neotrombicula. Altogether 5 species of the genera Neotrombicula (3 species) and Leptotrombidium (2 species) were feeding in the cochlea, and N. sympatrica amounted to 33.18% only. The greatest number of larvae (495) was recorded in the third silvery high-mountain vole (Inventory No. 545). 341 individuals were recorded in the cochlea; N. sympatrica amounted to 45.16% among them. Joint localisation was revealed for 5 species of the genera Neotrombicula (2 species), Leptotrombidium (2 species) and Aboriginesia ( 1 species). Six species of the genera Neotrombicula (3 species), Aboriginesia (1 species) and Leptotrombidium (2 species) were found feeding together in the cochlea of three individuals of the silvery high-mountain vole. Six species were also found stuck to the anogenital area, but already from 2 families: Neotrombicula (3 species), Leptotrombidium (2 species) and Shunsennia (1 species). N. sympatrica was found coexisting with 16 other species of chigger mites belonging to 9 genera and 2 families (Table 5). Inside the cochlea, N. sympatrica coexisted with all 16 species in 76 cases; however the greatest number of cases of coexistence (29) belonged to N. karashoriensis (19.74%) and N irata (18.42%). On the edge of the ear, the number of cases was 44. The highest rates of cases of coexistence belonged to N. irata (22.73%) and L. wolandi (20.45%). Further areas included the anus (26 cases), the genitals (20 cases), underside of the tail (9 cases), outside of the ear (3 cases) and the belly (3 meetings). One case was recorded only on a breast. The number of regions of coexistence of N. sympatrica was 5 with N. irata, L. wolandi, and S. oudemansi, and 6 with N. irata and N. karashoriensis. In total, N. sympatrica was found feeding together with other species of chigger mites in 182 cases; the highest number of cases belonged to N. irata (23.63%) andAf. karashoriensis (20.32%). 161 cases (49.94%) of coexistence of N. sympatrica with 15 species of chigger mites were revealed in combings. The total number of cases of coexistence (feeding mites and found in combings) of N. sympatrica with other species of chigger mites was 343.
