In the cochlea, N sympatrica coexisted with representatives of 8 genera; there were 5 genera in the ano-genital region, and 2 genera in the ventral region (Table 6). While feeding in the cochlea, N. sympatrica was most frequently contacting with species of its own genus (60.16% of all cases of coexistence) followed by representatives of the genera Leptotrombidium (25.20%) and Shunsennia (4.06%). In the ano-genital region the data were as follows: Neotrombicula 72.73% and Leptotrombidium 10.91%. In the ventral region, N. sympatrica preferred to feed together with species of its own genus as well (75.00% of Neotrombicula and 25.00% ofEuschoengastia). Most of the species feeding simultaneously with N sympatrica belonged to the genera Neotrombicula (6 species), Montivagum (3) and Leptotrombidium (2). Table 6.

Helenicula AuDY, 1954 0.81 SUMMARY In Kyrgyzstan the larvae of N. sympatrica were found feeding on 9 areas of the host's skin grouped in three topographical regions: cochlea (inside, edge and outside of the ear), ano-genital region (genitals, anus, under the tail) and ventral region (belly, breast, and chin). Mites were collected from 64 animals belonging to 8 species of rodents. In total, 2662 larvae of N. sympatrica were investigated The greatest number of mites feeding inside a cochlea was reached
