A total of 1,390 ectoparasitic flies were collected, belonging to 24 species of Streblidae and one of Nycteribiidae, parasitizing 227 bats of 15 species. Among the species found, the presence of Trichobius sp. on Lonchophylla mordax and the first occurrence of Hershkovitzia sp. on Thyroptera devivoi are highlighted. Lophostoma species presented the highest proportion of individuals with infracommunities and the highest values of parasitological indexes. The high number of bat fly species and hosts, as well as the high values for rates of parasitism and infracommunities, suggests that this area of cerrado has good shelter conditions for these species. The abundance of species and high rates of parasitism detracts from the hypothesis that a higher mean intensity of ectoparasites results from lower competition among flies for hosts in areas with lower ectoparasite species richness. Biogeographical and historical factors of host populations, besides the number of host species and individuals sampled, may contribute to species number and intensity of parasitism. Keywords Diptera, Streblidae, Nycteribiidae, Phyllostomidae, savannah, host-parasite associations Introduction Among the causes of variation in patterns of parasitism are characteristics both intrinsic to the host and to the parasite. By being associated with their hosts for most of their life cycles, their geographic distribution, behavior, body size, immune defenses and type of shelter are determinants in abundance and diversity of parasites in a region (Marshall 1982, ter Hofstede and Fenton 2005, Patterson et al. 2007). Moreover, the rate of reproduction, the reproductive behavior and sex ratio of ectoparasites (Reckardt and Kerth 2006, Dittmar et al. 2011), as well as the interspecific relationships in the same host (Patterson et al. 2009; Presley 2011) also contribute to their occurrence. The dipteran ectoparasites of bats, belonging to the families Streblidae and Nycteribiidae, are obligatorily hemato- phagous with great morphological variation and high specificity to their hosts (Marshall 1982, Wenzel et al. 1966, Dick 2007). In the neotropics, these families are distributed across various ecoregions (Prevedello et al. 2005), with more records in the Amazon region (Wenzel et al. 1966, Wenzel 1976, Guerrero 1997) and in deciduous forests of the south-central portion of the continent (Dick and Gettinger 2005, Bertola et al. 2005, Autino et al. 2009, Camilotti et al. 2010). In Brazil, the cerrado is characterized by diverse physiognomies and patterns of flora distribution throughout its extent (Oliveira-Filho and Ratter 2002). Therefore, this biome is of great importance for understanding the patterns of host-parasite associations in their remaining areas. In Brazil, studies on bats’ ectoparasitic flies in cerrado region have mainly comprised of faunal inventories (Graciolli and Coelho 2001; Graciolli and Aguiar 2002; Graciolli et al. 2006a, 2010).

In this paper we document the highest number of bat fly species relative to those previously reported from the Brazilian cerrado and describe quantitatively the associations between streblid and nycteribiid flies and their hosts. From the results discussed here, we intended to contribute to the knowledge of parasitism patterns of these Diptera in the cerrado and to encourage further research in other areas and cerrado physiognomies that have not yet inventoried. rainy season in the first six months of the year and drought in the other months (IMESC 2011). The predominant vegetation type is cerrado (sensu stricto), also showing formations of campo cerrado, cerradão, veredas and riparian forest, according to the classification of Oliveira-Filho and Ratter (2002). Bats were captured at 12 localities in cerrado (sensu stricto), each more than 3 km apart, and located approximately 200 m from roads. Between January and May 2011, five nights of capture were performed at each location (18h to 24h) during periods of waning and new moon. To capture the bats, we used 12 mist nets (2.5 m x 12 m) arranged in pairs, more than 20 m distant from each other. The total capture effort was 129,600 m².h according to standards proposed by Straube and Bianconi (2002). Materials and methods The study area is located in the municipality of Barreirinhas (3º0´S, 43º6´W), state of Maranhão, and represents the northern limit of cerrado in Brazil (Fig. 1). The climate is semi-arid hot tropical (Aw type according to Köppen’s classification – Peel et al. 2007), with mean annual temperature exceeding 27ºC. The annual rainfall varies between 1,200 mm and 1,600 mm, with For collection of ectoparasite flies, the bats’ body surface was searched and flies were collected with forceps and preserved in 70% alcohol. In order to identify the recaptures, all bats were marked, by cutting part of the dorsal fur, before being released. Bat species were identified according to the classification given by Gardner (2007). The ectoparasitic flies were identified using keys of Wenzel (1976), Wenzel et al. (1966) Fig. 1.

The voucher specimens of each species of bats and ectoparasites are deposited in the Zoological Reference Collection of the Federal University of Mato Grosso do Sul (ZUFMS) and in the Zoological Collection of the Laboratory of Entomology and Vectors, Federal University of Maranhão. We adopted the definitions proposed by Bush et al. (1997) for the component community (set of ectoparasite species found on one host species), infracommunity (community of ectoparasite populations on a single host), prevalence (number of infested hosts/number of captured hosts) and mean intensity of infestation (mean of parasites per infested host). The percentage of the total abundance of a single ectoparasite species found on each host species is presented in the specificity index, according to Dick and Gettinger (2005). To calculate the confidence intervals for the prevalence and mean intensity of infestation we used the software Quantitative Parasitology 3.0 (Rózsa et al. 2000). Infestations in non-primary hosts occurred on nights when the main host was captured were considered accidental, according to Dick (2007). Results We captured 487 bats belonging to 27 species and four families (Molossidae, Phyllostomidae, Vespertilionidae and Thyropteridae). The phyllostomid species totaled 85.2% of the captures, the most abundant being Artibeus cinereus Gervais, Table I.

We collected 1,390 ectoparasitic flies, representing 24 species (10 genera) of Streblidae and one of Nycteribiidae; N % 4 19 among them, 22 (88%) were monoxenous (associated with a single host species), two oligoxenous (present in congeneric host species) and one polyxenous (associated with non-congeneric host species). Four bats with ectoparasites were recaptured: three individuals of the species C. perspicillata – infested by 12 flies of the species Trichobius joblingi Wenzel, 1966, one of Speiseria ambigua Kessel, 1925 and one of Strebla guajiro (García et Casal, 1965); and one individual of Lonchophylla mordax Thomas, 1903 parasitized by the streblid Trichobius sp. The streblids on hosts that were recaptured were not considered for analyzing the patterns of parasitism, since they do not represent an independent sample of the population. Most host-parasite species associations were exclusive (68.7%), with specificity index equal to 100% (Table I), and with one streblid species (59.5% of infested hosts). The species with the highest number of infracommunities of ectoparasites was L. carrikeri, with 44.7% of associations with three streblid species and 48.9% with two (Table II). Regarding the ectoparasites, the species with highest number of nonaccidental associations was Mastoptera minuta (Costa Lima, 1921), found in four host species.

In cerrado areas, other studies have recorded fewer species, including Graciolli et al. (2010, 21 species), Eriksson et al. (2011, 17) and Komeno and Linhares (1999, 12). Among factors that may attribute to the highest number of bat fly species found in the cerrado, we propose: 1) the study area’s location near the Amazon eastern transition zone (Ab ‘Saber 1977), which includes the distributional limit of various host species (Simmons 2005) that can support different component communities; 2) factors external to the host that can affect the abundance of ectoparasites and their hosts, such as the type of climate, vegetation (Prevedello et al. 2005) or host shelter (Wenzel et al. 1966, Patterson et al. 2007); 3) the highest number of individuals and host species than those reported in other studies with less rich and abundant fauna, such as those conducted in deciduous forest (Camilotti et al. 2010) and caatinga (Rios et al. 2008), a result that could favor the sample of host species with different component communities as well as the finding of bat fly species that occur in low prevalence in their host species; 4) the major sampling effort that may contribute to the finding of more host species and individuals, which is comparable just to the realized in Atlantic forest by Bertola et al. (2005, with 84% of our sampling effort and 22 bat fly species) and is greater than the others already carried out in cerrado (Graciolli et al. 2010, Eriksson et al. Brought to you by | Fundação Universidade Federal do Mato Grosso do Sul UFMS Authenticated Download Date | 9/24/15 8:04 PM 211 Parasitism on bats in the northern cerrado boundary 2011) – that had, at most, the half of the sampling effort of this study. Changes in component communities of ectoparasitic flies in host species can be attributed to the regional differences in species composition of bats, to the biogeographic history of the area or to the lack of specificity of ectoparasites (Rui and Graciolli 2005). In addition to the new records of associations (Table I), we found the following variations in the component communities: the absence of Paraeuctenodes similis Wenzel, 1976 on C. perspicillata, association observed in regions of Atlantic forest (Bertola et al. in 2005, Prevedello et al. 2005) and Amazon forest (Guerrero 1996); the absence of Metelasmus pseudopterus Coquillet, 1907, which is found parasitizing species of Artibeus from the south-central Brazil (Eriksson et al. 2011, Bertola et al. 2005); the lower number of ectoparasitic species on Desmodus rotundus (E. Geoffroy, 1810), that in other areas of cerrado is also parasitised by Trichobius furmani Wenzel, 1966 and Strebla wiedemanni Kolenati, 1856 (Eriksson et al. in 2011, Aguiar and Antonini 2011); the absence of Trichobius uniformis Curran, 1935 and Strebla curvata Wenzel, 1976 on Glossophaga soricina (Pallas, 1766), found on this species in cerrado areas (Eriksson et al. 2011, Graciolli et al. 2010), in addition to the parasitism by Paraeuctenodes longipes Pessoa et Guimaraes, 1937 recorded in the southern Brazil (Graciolli and Rui 2001). It is also highlighted the absence of parasitism on A. cinereus, a species with register of parasitism by ectoparasitic flies of the genus Neotrichobius Wenzel and Aitken, 1966 in the Amazon region (Guerrero 1994a). Only two accidental associations were recorded, T. joblingi on L. carrikeri and Stizostrebla longirostris Jobling, 1939 on Lophostoma silvicolum Tomes, 1863. Excluding these associations, we found a proportion of monoxenous species (88%) similar to the study performed by Dick and Gettinger (2005, 87.1%), who also prioritized methods that reduced the number of accidental associations. The only polyxenous species found (M. minuta) is currently grouped into a complex, by having little morphological variation among individuals from different host species (Wenzel 1976). However, its greater specificity recorded in Lophostoma (99.6%) in this study corroborates its high abundance on bats of this genus (Guerrero 1995, Wenzel 1976). The prevalence and mean intensity of infestation of T. joblingi on C. perspicillata (54.7% and 2.3, respectively) had a value intermediate to those found in other regions of cerrado by Komeno and Linhares (1999, 66%, 2.1) and Eriksson et al. (2011, 40.5%, 2.8). We observed this difference in prevalence also in the associations between: Trichobius parasiticus Gervais, 1844 and D. rotundus (53.3%), higher than those recorded in Paraguay (Dick and Gettinger 2005, 31.4%) and in caves from the central-western Brazil (Aguiar and Antonini 2011, 29.5%); Aspidoptera falcata Wenzel, 1976 and Sturnira lilium (E. Geoffroy, 1810) (66.7%), with higher values than those observed in cerrado (Eriksson et al. in 2011, 21.3%), Atlantic forest (Graciolli et al. 2006b, 10%) and Araucaria for- est (Graciolli and Bianconi 2007, 13.5%). Although most studies do not show the confidence interval of ectoparasite prevalence, this variation among values observed in studies from different regions supports the hypothesis that the streblid distribution in the different host populations is highly variable (Graciolli and Bianconi 2007). The protection and durability of host’ shelters are factors that favor the increase of infestation of flies on bats, since they favor the development of ectoparasite pupae in these shelters (ter Hofstede and Fenton 2005) and favor the likelihood of bats to colonize upon eclosion (Patterson et al. 2007). Among the parasitized species found, there was a higher proportion of phyllostomines (46.7%) and nectarivorous (20%) bats than in other studies in the Neotropics with similar capture effort, in which represented less than 40% of species infested (Bertola et al. 2005, Eriksson et al. 2011, Komeno and Linhares 1999). The species of these groups have more durable shelters, mainly inhabiting hollow trees, caves and nests of termites (Fenton et al. 2001, Bernard and Fenton 2003). This major occurrence of phyllostomines and nectarivorous species possibly have contributed to the greatest number of bat flies species recorded, since their roosting habits could favor them to harbor parasites (Patterson et al. 2007). Likewise, the lower frequency of parasitism on stenodermatines, the most abundant group found, may be related to their lower fidelity and durability of their shelters, since these bats refuge mainly in foliage and may change shelter more frequently (Fenton et al. 2001). The associations of Pseudostrebla greenwelli Wenzel, 1966, Strebla tonatiae (Kessel, 1924) and Trichobius silvicolae Wenzel, 1976 with L. silvicolum, in spite of having low prevalence, were considered natural, since their primary hosts were not captured on the same night. Pseudostrebla greenwelli and S. tonatiae are found mainly in Lophostoma brasiliense (Peters, 1866) (Guerrero 1994a, Dias et al. 2009, Graciolli and Bernard 2002), the first having only six specimens in collections (Guerrero 1996, Graciolli and Bernard 2002). However, the species T. silvicolae, although appearing with greater prevalence in L. brasiliense, parasitizes mainly L. silvicolum (Wenzel 1976, Graciolli and Bernard 2002). The species of Lophostoma primarily use termite nests as shelter (Bernard and Fenton 2003, Kalko et al. 1999), which in cerrado areas play a key role as refuges resistant to seasonal burning (Redford 1984). Since L. silvicolum had been found in three of the four capture points where L. brasiliense was present, the inverse prevalence of ectoparasitic flies between these hosts species may be related to shelter sharing by individuals of Lophostoma. The low availability of termite nests in the study area for the abundance of Lophostoma observed may be the reason for this probable sharing, as well as for the highest values of the parasitological indexes in these species (Table I). In the neotropics, bat species harboring more than one fly species has been observed also in areas of tropical forest (Teixeira and Ferreira 2010, Bertola et al. 2005), cerrado Brought to you by | Fundação Universidade Federal do Mato Grosso do Sul UFMS Authenticated Download Date | 9/24/15 8:04 PM 212 Ciro Líbio Caldas dos Santos et al. (Aguiar and Antonini 2011), Venezuela (Wenzel 1976) and eastern Amazon forest (Santos et al. 2009). In this study, the highest proportion of hosts with infracommunities of ectoparasitic flies (40.5%) was found mainly in Lophostoma species (Table II). We note also the occurrence in all infracommunities of the same host species the presence of the most abundant fly species (M. minuta, T. costalimai and T. joblingi), co-occurrence pattern also observed in other studies in the parasitism of M. proxima on S. lilium (Bertola et al. 2005), T. joblingi on C. perspicillata and T. costalimai on P. discolor (Santos et al. 2009). With the exception of species of Lophostoma, all infracommunities of other host species had been recorded in other studies (Bertola et al. 2005, Santos et al. 2009). Regarding the number of individuals with infracommunities, we found a value higher than that reported by Bertola et al. (2005) and Santos et al. (2009) for S. lilium, even with less number of infestations (four) in this species. In C. perspicillata, we observed lower proportion of individuals infected with infracommunities (25.4%) than in these studies, which have captured less infested individuals (30 and 12, respectively). The variation in the frequency of infracommunities of flies may suggest the existence of ecological factors of the bats (e.g., type of shelter or level of aggregation within their colonies) which should facilitate finding hosts by parasites, which in turn would favor the co-occurrence of fly species (Presley 2011). This relationship may be responsible for higher incidence of infracommunities of flies on hosts with more durable shelters, as the species of Lophostoma herein recorded. The high number of bat fly species and hosts, as well as the high values of parasitism rates and infracommunities, shows that the northern cerrado area has good shelter conditions for these species. This abundance of both species and ectoparasites per host is opposed to the hypothesis that a higher mean intensity of ectoparasites would be a result of less competition for hosts by flies in areas with lower richness of ectoparasite species (Camilotti et al. 2010). Probably, biogeographical and historical factors of host populations in each area, besides the number of species and individuals sampled, should also have their contribution in species number and intensity of infestation of ectoparasites. However, further efforts are needed to understand the processes influencing patterns of parasitism over the distribution of ectoparasite fly species, in order to relate them to different types of climate, vegetation and host populations in the Neotropics.
