BAT FLY (DIPTERA: STREBLIDAE) PARASITISM IN DEGRADED AND PRESERVED AREAS IN A NEOTROPICAL SAVANNA.

We assessed the relationship between bat fly parasitism and habitat degradation. We used mist nets to capture 522 individuals of Carollia perspicillata and 429 individuals from eight fly species in the Brazilian Cerrado. Specimens were captured in degraded areas surrounding protected areas and within the protected areas. Trichobius joblingi was the most frequent parasite of Carollia perspicillata; consequently, it was analyzed in greater detail. Sex and age were not critical factors for parasitism. A robust anthropogenic influence was observed; unexpectedly, a higher prevalence and abundance of bat flies were observed in preserved areas. [ABSTRACT FROM AUTHOR]
