Habitat fragmentation and the prevalence of parasites (Diptera, Streblidae) on three Phyllostomid bat species

Ectoparasitism in bats seems to be influenced strongly by the type of roost preferred by the hosts, and group size; however, the effect of habitat loss and fragmentation on the prevalence of ectoparasites in bats has scarcely been studied. In northeastern Yucatan, Mexico, we estimated the prevalence of infestation by Streblidae flies in three phyllostomid bat species with different roost preferences (caves, trees, or both) in two types of landscape matrices (tropical semi-deciduous forest and man-made pastures) that differed in area of forest cover and the number of forest fragments. Habitat fragmentation and the presence of a contrasting matrix may limit the availability of roosts (trees) and the movement of bats across the landscape. Accordingly, we hypothesized higher prevalence of Streblidae infestation in the pasture matrix and in the group of bats that roost in trees. Bat abundance was higher in the pasture matrix; however, the prevalence of infestation was significantly higher in the continuous forest matrix and in bats that roosted in caves. The prevalence of some species of Streblidae was affected by habitat fragmentation in species that roost in caves, such as Desmodus rotundus, as well as those using foliage and caves, such as Artibeus jamaicensis. Our results provide evidence that some species of Streblidae may respond differently to habitat fragmentation than their hosts, generating changes to bat-ectoparasite interactions in fragmented areas. Environmental variations involving roosts, not evaluated in this study, may influence our results, since these factors affect ectoparasite abundance and reproduction.Abstract in Spanish is available with online material.

“…This pattern was not observed in the present study. The competition between parasite species does not seemed to affect the infracommunities of bat flies, but probably the ecology, behavior, and morphology of the host can affect the occurrence of these infracommunities (Tello et al, 2008;Presley, 2011;Patrício et al, 2016).…”

The objective of this work was to evaluate the occurrence and infestation rates of Streblidae species on bats in a semideciduous seasonal forest fragment in western Paraná, South of Brazil. A total of 289 specimens of eight Streblidae species were collected from six species of bats belonging to the family Phyllostomidae. The most frequent Streblidae species were Megistopoda proxima (Séguy, 1926), Aspidoptera falcata Wenzel, 1976 and Paratrichobius longicrus (Miranda Ribeiro, 1907). The highest prevalence found was Megistopoda aranea (Coquillet, 1899) on Artibeus planirostris (Spinx, 1823). The highest intensity found was M. aranea on Artibeus lituratus (Olfers, 1818). The highest abundance found was M. proxima on Sturnira lilium (E. Geoffroy, 1810). All recorded species were highly specific to their hosts, except M. aranea. Two infracommunities were recorded: M. aranea and Metelasmus pseudopterus (Coquillett, 1907) on A. planirostris, and M. proxima and A. falcata on S. lilium. The results showed a trend of occurrence of ectoparasites on females, considering the most frequently captured bats, the seasons had no pattern in the prevalence and intensity factors in this sampling area to them. Studies evaluating the life cycle of these parasites, and the behavior and morpho-physiology of these hosts are necessary since the parasitism rate can be affected by other factors that were not evaluated in this study.

“…Nonetheless, this increased susceptibility has been not found for A . planirostris juveniles or pregnant females (Patrício et al ., 2016). We raised that small and ephemeral tree hollows available for A. planirostris in the Pantanal could favour an increased aggregation of parasites across host individuals if compared with large and perennial rocky shelters available in the plateaus (Sallun-Filho et al ., 2010).…”

“…In all sites, at least 30 individuals of A. planirostris were captured. We considered all captured individuals regardless of age, sex or reproductive stage because effects of these traits on bat flies is unclear (Bertola et al, 2005;Patrício et al, 2016), and because we did not find significant differences in the proportion of the host age, sex or reproductive stage between regions. We inspected every captured A. planirostris individuals for ectoparasites, collected the streblids manually or with tweezers, and stored them in microtubes containing 1.5 mL of 70 or 99% alcohol.…”

Bat flies aggregation onArtibeus planirostrishosts in the Pantanal floodplain and surrounding plateaus

For parasites in natural systems, the most common pattern of spatial distribution is aggregation among hosts. The main causes of such aggregation are variable exposure of hosts to parasites and heterogeneity in host susceptibility. The objective of this study was to determine if there are differences in the aggregation pattern of two species of ectoparasitic flies between the Pantanal and Cerrado regions of Brazil on the bat Artibeus planirostris. We collected the ectoparasites from bats captured between 2002 and 2017 with mist nets in 21 sites in the Pantanal and 15 sites in the surrounding plateaus. The results showed that the aggregation of ectoparasitic flies in Pantanal was more pronounced than in Cerrado. The discrepancy aggregation index (D) of the bat fly Megistopoda aranea was 0.877 in Pantanal and 0.724 in Cerrado. The D values of Aspidoptera phyllostomatis was even higher, with 0.916 and 0.848 in the Pantanal and Cerrado, respectively. Differences in the shelters used may be the main factor shaping variation in aggregation, since the Pantanal does not have rock formations, with only foliage, crowns and hollow tree trunks. These differences likely affect host exposure to the parasites, leading to an increase in parasite aggregation.
