The mark-recapture method allows analysis on the variation in the abundance of bat ectoparasites at consecutive captures. The objectives of this study were to compare the pattern of Streblidae parasitism between capture and recapture of C. perspicillata; ascertain whether the abundance of Streblidae varied with time after removal of ectoparasites at capture and analyze whether the intensity of parasitism remained the same in each individual at capture and recapture. Using bats netted in the State of Rio de Janeiro, 42 individuals of C. perspicillata parasitized by two Streblidae species, Trichobius joblingi Wenzel, 1966 and Strebla guajiro (Garcia & Casal, 1965), were selected. The pattern of parasitism observed at capture was similar at recapture. No relationship was observed between the capture-recapture time interval and the abundance of ectoparasites. There was no relationship between the abundances of ectoparasites at capture and recapture of each individual.
标记重捕法可用于分析连续捕获时蝙蝠体外寄生虫数量的变化情况。本研究的目的是比较在捕获和重新捕获短尾果蝠时蝠蝇科寄生虫的寄生模式；确定在捕获时去除体外寄生虫后，蝠蝇科的数量是否随时间变化，并分析在捕获和重新捕获时每个个体的寄生强度是否保持不变。利用在里约热内卢州捕获的蝙蝠，选取了42只被两种蝠蝇科物种寄生的短尾果蝠，这两种物种分别是1966年的约氏毛鼻蝠蝇和1965年的瓜希罗蝠蝇。在捕获时观察到的寄生模式在重新捕获时相似。未观察到标记重捕时间间隔与体外寄生虫数量之间的关系。每个个体在捕获和重新捕获时体外寄生虫的数量之间也没有关系。
