Bat flies are known to carry bat-related pathogens, therefore, are potential vectors of bat-related zoonoses. However, the capacity of bat flies in spreading bat-related infectious diseases depends on their host specificity. Two main mechanisms that have been proposed to affect host specificity of parasites are how easy parasites can "encounter" different hosts and "compatibility" of parasites, i.e., ability of parasites to survive and multiply on different hosts. Although bat flies have high degree of host specificity, few studies have been conducted to assess the relative importance of "encounter" and "compatibility" in affecting host specificity of bat flies. Therefore, we intend to evaluate the relative importance of "encounter" and "compatibility" in affecting host specificity of bat flies by transferring bat flies, Penicillidia jenynsii, which were collected from the cave-dwelling Japanese long-fingered bats (Miniopterus fuliginosus), to other 12 bat species in Taiwan. Taxonomy of Taiwan bat flies and their host list will also be created and updated by extensive filed survey of bats and bat flies in Taiwan. Results of the 2015-2016 project revealed 9 new record species of bat flies (3 Streblidae and 6 Nycteribiidae) in Taiwan. P. jenynsii can survive by feeding the blood of 11 out of 12 bat species tested (internal compatibility). However, P. jenynsii failed to survive on Rinolophus monoceros which is co-habited with M. fuliginosus. Although P. jenynsii has the potential of infecting more host species, it may show high degree of host specificity due to its preference. This project will continue to investigate how “preference” of bat flies and other relevant mechanisms affect host-parasite compatibility.蛛蠅科蝙蝠蠅科宿主專一性遭遇相容性偏好NycteribiidaeStreblidaehost-specificityencountercompatibilitypreference臺灣蝠蠅宿主專一性研究(三)
