RESUMO

In order to study the association between ectoparasitc arthropods and phyllostomid bats, 35 nightly collections of bats and their ectoparasites were made using mist nets, at the "Reserva Ecologica do Panga" (Uberlandia, MG), from August 1989 to July 1990. Twelve species of bats, 11 of Streblidae, 1 of Nycteribiidae and mites of the genus Periglischrus were collected. The fly Trichobius joblingi was found on Carollia perspicillata, showing preference for the wing membranes of adult male hosts. This preference for males could be explained by the predominance of this sex in colonies, and by the fact that females rest in isolation during the reproductive period. Hence, it was concluded that ecological factors are of importance in determining the preference of the parasit for sex and stage of development of the host. The flies Aspidopotera falcata and Megitopoda proxima were found on Sturnira lilium. The first parasite species showed preference for young and adult females, whereas M proxima did not show any preference in relation to sex and developmental stage of the host. However, A. falcata was found mostly on the wings and M proxima preferred the body of the host. In addition, there was a seasonal differentiation between the two Streblidae species. These differences can be explained by inter specific competition. In general, ectoparasites seasonality did not show any difference between dry and wet seasons, leading to the conclusion that it is related to the seasonality of the hosts
