| Abstract: | Virgin and cultivated biotopes of the Sea of Azov area of Donetsk Province were investigated for parasite coenoses of small mammals. 469 animals and 210 nests were collected, Apodemus sylvaticus, Mus musculus, Microtus arvalis and Cricetulus migratorius being the most abundant species. In all 2940 larvae of trombiculids (18 species) were found on animals and in their nests (2846 specimens on animals and 94 specimens in nests). Two species, Hoffmannina theodori and Doloisia skljari, are new for science, the latter being the first find of the genus Doloisia member in the fauna of the USSR. The majority of parasites are collected from rodents inhabiting virgin biotopes (2328 specimens) while in cultivated biotopes 189 specimens were collected. More rich is the species composition of trombiculids in virgin biotopes (13 species) as compared to that in cultivated ones (5 species), Neotrombicula earis, N. japonica, N. autumnalis and N. vulgaris being mass species. 8 species of larvae are recorded from the nests of rodents. Seasonal dynamics of the abundance of mass species, their occurrence, index of abundance and infection intensity are shown. |
