Abstract

  • At three bird ringing stations in eastern Austria, a total of 298 louse flies of nine different species were collected between 2013 and 2022. These came from a total of 228 birds of 38 different species of predominantly passerine birds. The records of Icosta minor (Bigot in thomson, 1858) and Ornithomya chloropus (Bergroth, 1901) are the only ones from Austria so far. Also, the numerous records of Ornithoica turdi (latreille, 1812), which is more common in the Afrotropis, and the generally rare Ornithophila metallica (schiner, 1864) are remarkable. In all species, females clearly outnumbered males. Comparing the most common reed warblers and tits, the smaller birds were more often parasitized by Ornithomya fringillina curtis, 1836 and the larger ones by Ornithomya avicularia (linnaeus, 1758). Phoresy with mites occurred in five louse fly species, with O. turdi showing the highest phoresy rate of 25%. In one case, two different louse fly species were found on a Common Blackbird at the same time. The monoxenous Ornithomya biloba (dufour, 1827) lives on Barn Swallows, but was also found on a Eurasian Wryneck, a Sand Martin, a Common Kingfisher and a Eurasian Blackcap. Furthermore, the mammalian louse fly Lipoptena cervi (lin-naeus, 1758) was found on a Dunnock. In one case, the malformation of a wing was observed in Ornithomya biloba. Zusammenfassung Lausfliegen-Nachweise von drei Vogelberingungsstationen in Ostösterreich von 2013 bis 2022 (Di ptera: Hippoboscidae). − In drei Vogelberingungsstationen im Osten Österreichs wurden in den Jahren 2013 bis 2022 insgesamt 298 Lausfliegen neun verschiedener Arten gesammelt. Diese stammten von insgesamt 228 Vögeln von 38 verschiedenen Arten. Dabei handelte es sich vorwiegend um Sperlingsvögel. Die Funde von Icosta minor (Bigot in thomson, 1858) und Ornithomya chloropus (Bergroth, 1901) stellen die bislang einzigen Nachweise aus Österreich dar. Bemerkenswert sind ferner die zahlreichen Belege der in der Afrotropis häufigeren Ornithoica turdi (latreille, 1812)
