Prevalence of bat ectoparasites on sympatric Myotis lucifugus and M. septentrionalis was quantitatively characterized in Nova Scotia and New Brunswick by making systematic collections at swarming sites. Six species of ectoparasite were recorded, including Myodopsylla insignis, Spinturnix americanus, Cimex adjunctus, Macronyssu scrosbyi, Androlaelap scasalis, and an unknown species of the genus Acanthophthirius. Male M. lucifugus and M. septentrionalis had similar prevalence of any ectoparasite (22% and 23%, resp.). Female M. lucifugus and M. septentrionalis had 2-3 times higher prevalence than did conspecific males (68% and 44%, resp.). Prevalence of infection of both genders of young of the year was not different from one another and the highest prevalence of any ectoparasite (M. lucifugus 64%, M. septentrionalis 72%) among all bat groups. Ectoparasite prevalence and intensity varied positively with roost group size and negatively with grooming efficacy and energy budgets, suggesting that these variables may be important in ectoparasite community structure.
通过在群居地点进行系统采集,对新斯科舍省和新不伦瑞克省同域分布的北美鼠耳蝠和北方鼠耳蝠身上的蝙蝠体外寄生虫的流行情况进行了定量描述。记录了六种体外寄生虫,包括无斑鼠蚤、美洲蝠螨、副臭虫、克氏巨螨、斯氏安德罗巨螨,以及棘虱属的一个未知物种。雄性北美鼠耳蝠和北方鼠耳蝠身上出现任何一种体外寄生虫的流行率相似(分别为22%和23%)。雌性北美鼠耳蝠和北方鼠耳蝠身上的流行率比同种雄性高出2至3倍(分别为68%和44%)。当年幼蝠两性的感染流行率彼此无差异,且在所有蝙蝠群体中,出现任何一种体外寄生虫的流行率最高(北美鼠耳蝠为64%,北方鼠耳蝠为72%)。体外寄生虫的流行率和感染强度与栖息地群体大小呈正相关,与梳理效率和能量收支呈负相关,这表明这些变量可能对体外寄生虫群落结构很重要。
