Abstract

Data on fauna of gamasina mites parasitizing on small mammals are provided in article. Data are obtained during long-term monitoring of an ecological complex of small mammals of a natural and territorial complex Samarskaya Luka, which is realized since 1999. Also data on fauna of gamasina mites in 14 years of researches (20002003, 2005, 20072015 years), including literary data about the gamasina mites of this territory, are generalized and analysed. Specific accessory of 7439 individuals of mites, seven childbirth of three families relating to fifteen types is defined. Parasitizing the gamasina mites on 16 species of small mammals, including groups rodents, soricomorpha, carnivora (least weasel) is established. Domination of separate species of mites is revealed, so to eudominant Laelaps hilaris and Hirstionyssus isabellinus are belong, dominants are Hirstionyssus ellobii, Haemolaelaps glasgowi, Hyperlaelaps arvalis, L. agilis. Myonyssus rossicus, L. algericus, Haemogamasus ambulans and Hirstionyssus macedonicus were extremely rare species met in single copies. For the first time for this territory types of H. ellobii, L. micromydis, H. ambulans, H. macedonicus are noted. Conclusions on degree of a confinedness of parasites to certain types of hosts are drawn. Monohostal types: L. agilis (the host a yellow-necked mouse), L. muris (the host a tundra vole and a water vole), L. micromydis (the host a small mouse), L. algericus (the host a house mouse), H. arvalis (the host a tundra vole and a water vole), H. ellobii (the host a northern mole vole). Polihostal: H. musculi, L. hilaris, H. isabellinus, H. glasgowi, E. stabularis, H. nidi.

Summary

Introduction

In the article contains information about present state of specially protected natural area, natural monument of regional significance «Sources of the Krymza River» (Syzransky District, Samara Region), its flora, vegetation and rare plant species. Целью наших исследований на данном этапе явилось установление наиболее полного видового списка гамазовых клещей, паразитирующих на мелких млекопитающих на территории природно-территориального комплекса «Самарская Лука». Для установления степени доминирования видов в сообществе гамазовых клещей на территории Самарской Луки, использовалась система, предложенная Райским: эудоминант – более 15% от общего числа в сборах, доминант – 5,1–15%, субдоминант – 2,1– 5%, редкий – 1,1–2%, крайне редкий – менее 1,1%.
