摘要

本研究針對南投縣地利地區的摺翅蝠(Miniopterus schreibersii)群集進行寄生於蝙蝠體外之蝠蠅種類鑑定，並檢驗蝙蝠的體重與性別對於寄生蝠蠅豐富度之影響情形。2007年9月至2008年8月共採樣了570隻摺翅蝠成蝠，從牠們身上共採集到2,698隻蝠蠅。蝠蠅皆隸屬於蛛蠅科(Nycteribiidae)，共2屬，其中屬於毛刷蛛蠅屬的姜宜蛛蠅(Pencillidia jenynsii)1種（310隻），而蛛蠅屬有2種，分別爲短鋏蛛蠅(Nycteribia parvula)（1,425隻）及長鋏蛛蠅(N. allotopa mikado)（963隻）。蝙蝠的體重與性別對蝠蠅豐富度影響的結果顯示，僅有短鋏蛛蠅的豐富度在體重較輕或較重二類群宿主間出現顯著性差異。

We investigated ectoparasitic flies of the bat Miniopterus schreibersii and determined the effects of sex and body weight of the bat on the fly abundance. About 30 adult males and 30 adult females of the bat was collected monthly at a predawn with a harp trap at the outlet of the water tunnel in Di-Li, Nantou County, Taiwan, September 2007 to August 2008. A total of 2,698 individuals of the bat flies were collected from 570 individuals of the bat. Three species of the bat flies were identified. They were Pencillidia jenynsii, Nycteribia parvula and Nycteribia allotopa mikado, belonging to the family Nycteribiidae. Only the abundance of N. parvula was found to correlate significantly with body weight of the bat.
