Arthropods – Inhabitants of Burrows of the Sand Martin Riparia riparia (Linnaeus, 1758) (Aves: Hirundinidae) on the Territory of the Saratov Province

The paper presents the results of nidicola fauna studies from burrows of sand martin Riparia riparia (Linnaeus, 1758) in the territory of the Krasnoarmeisk, Engels, Voskresensk, and Rovnoe Districts of the Saratov Province. 5859 specimens of arthropods belonging to 41 taxons from 26 systemic groups were collected in 97 burrows of the species. The focus is put on potential possibility of arboviral infection transmission from bank swallows to field sparrows (with participation of common ectoparasites), and through them – to humans.
