| Summary: | Rodents are one of the largest groups of existing mammals and number more than 2,270 known species, which is almost 42 % of the total biodiversity of worldwide-distributed mammals (except Antarctica and some islands). They are well adapted to various habitats and are known to live alongside people and livestock complexes. The purpose of the study was to study infestation of mice with ixodid ticks in forests of the Belgorod region adjacent to livestock and poultry farms. The study was carried out in 2019-2022. The extensiveness of mice infestation was observed in Sylvaemus sylvaticus species, which was 13.26 % higher (P 0.05) than in Sylvimus flavicollis , and 24.33 % higher (P 0.01) than in Apodemus agrarius . The intensity of infestation with preimaginal (larvae and nymphs) stages of Ixodes ricinus ticks had wide fluctuations depending on the type of synanthropic rodent. Thus, the highest intensity was noted in Sylvaemus sylvaticus mice, which was 8.73 and 13.56 % higher (P 0.001) compared to Sylvimus flavicollis and Apodemus agrarius mice, respectively. The maximum infestation of male synanthropic mouse species was 31 ticks in Sylvaemus sylvaticus , 19 ticks in Sylvimus flavicollis , and 9 ticks in Apodemus agrarius . The intensity of infestation in synanthropic mice was the highest in the summer months (from July to August) and decreased slightly in autumn. In autumn, 41.2 % of the examined rodents were infested with ticks, the predominant species was Ixodes ricinus (larvae). Larvae and nymphs of Ixodes ricinus ticks were more often attached to rodents in the head area (mainly on the ears) - 82 %, less often on other parts of the body - 1 8 %. A smaller number of ticks were present on neck, body, legs, sometimes parasites were found on tail. |
