Паразитические насекомые в гнездах Passer domesticus (linnaeus, 1758) и P. Montanus (linnaeus, 1758) (aves: passeriformes) в г. Воронеже

Abstract

In Voronezh, 14 species of parasitic insects were found in sparrows and their nests during 2017–2020. It was found 6 species of chewing lice: Menacanthus eurysternus Giebel, 1874, Ricinus fringillae De Geer, 1778, Sturnidoecus ruficeps Giebel, 1866, Brueelia subtilis Giebel, 1874, B. borini Lunkaschu, 1970, and Philopterus montani Zlotorzycka, 1964. Among them, Menacanthus eurysternus was the dominant species for the House Sparrow (dominance 21.70 %, prevalence 10.00) while B. subtilis (dominance 18.60 %, prevalence 8.00) and B. borini (dominance 16.29 %, prevalence 6.00) were subdominant. For the European Tree Sparrow, the dominant species were B. borini (dominance 22.07 %, prevalence 8.00) and Ph. montani (dominance 22.07 %, prevalence 10.6). All six chewing lice species were observed for the first time in Voronezh and the Central Black Soil Region of Russia. Three species of fleas – Ceratophillus gallinae (Schrank, 1803), C. fringillae Walker, 1856, and C. tribulus Jordan, 1926) – were registered. The dominant flea species was C. gallinae (for the House Sparrow, dominance was 67.13 %, prevalence 45.00; for the Tree Sparrow, dominance was 66.47 %, prevalence 73.33). Abundance of fleas for House Sparrow nestlings was 0.724, and 1.153 for Tree Sparrow nestlings. Parasitic flies were represented by five species: Ornithomya avicularia (Linnaeus, 1758), O. fringillina Curtis, 1836, O. chloropus Bergroth 1901 (Hippoboscidae), Protocalliphora azurea Fll., 1817, and Trypocalliphora braueri (Hendel, 1901) (Calliphoridae). Among louse flies O. avicularia was the dominant species (for House sparrow, dominance was 85.93 %, prevalence 53.00; for Tree Sparrow, dominance was 68.64 %, prevalence 20.00). Larvae of P. azurea were found in 13.00 % of House Sparrow nests and in 15.00 % of Tree Sparrow nests. For House Sparrow nestlings, intensity was 3.42 % with abundance 0.30, while for Tree Sparrow nestlings, intensity was 0.15 % with abundance 2.05. Larvae of T. braueri were found in 31.00 % of House Sparrow nests and in 40.00 % of Tree Sparrow nests. For House Sparrow nestlings, intensity was 0.164 with abundance 0.088. For Tree Sparrow nestlings, intensity was 0.106 with abundance 0.220. Significant fluctuations of prevalence and abundance of the larvae in different years were found.
