“…This observation is consistent with the findings of Esbérard et al (2005), which indicate that the determination of host specificity of a parasite is a very complex issue involving anatomical, physiological, evolutionary and behavioural adaptations. Further studies should be carried out to assess spatial and temporal infestation preferences in different regions of the host body and at different times of the day (Bittencourt & Rocha 2002) and to increase our understanding of some of the complicating factors that determine host specificity.…”

We studied the ectoparasitic bat flies of three phyllostomid vampire bat species. Bats were collected monthly from April 2004-March 2005 True ectoparasites spend most of their adult lives, or all developmental phases, on the bodies of their hosts or in their hosts' shelters (Marshall 1982). Streblidae (Diptera: Hippoboscoidea) are obligate ectoparasites of bats (Dick & Patterson 2008) and, consequently, are found primarily in tropical areas with relatively few species in the subtropical and warm temperate zones .Knowledge of bat ectoparasites has provided important information on the host's biology, systematics and phylogeny (Fritz 1983) and is essential for better understanding the ecology of bats and bat behaviour in shelters. This knowledge has also explained aspects of larviposition and infestation by ectoparasites and the epidemiology of pathogen transmission in bats (Komeno & Linhares 1999).The host's roosting habits are important factors in the bat-ectoparasite system (ter Hofstede et al. 2004, Patterson et al. 2007, Seneviratne et al. 2009). The variability in bat roosting preferences and ectoparasite fauna provides significant insights relating to parasite ecology and specificity (ter Hofstede et al. 2004). Host specificity is typical for parasite-host associations and is often even higher in obligate or permanent parasite associa- tions (Dick et al. 2009). Ectoparasites can be classified as heteroxenous when they can infest many species in many genera, monoxenous when they are found on only one host species, stenoxenous when they are found on host species of the same genus and oligoxenous when they are found regularly on hosts of different genera (ter Hofstede et al. 2004).The Brazilian savannah, also known as the cerrado, covers approximately two million km 2 of Central Brazil and is considered one of the richest and most threatened biodiversity reservoirs in the world (Mittermeier et al. 2005). This region is responsible for most Brazilian soy and corn production and ranching in this region produces almost 40 million heads of cattle per year (Aguiar et al. 2008). Bats account for nearly 50% of the total mammalian fauna of the cerrado biome (Aguiar & Machado 2010). This generates a great deal of concern due to their association with rabies, though most rabies cases are caused by just one vampire species, Desmodus rotundus (Gonçalves et al. 2002). Of the vampire bat species, D. rotundus is the most common and widespread species in Central and South America. Their primary food source is mammalian blood, but they also feed on avian blood. The two other vampire bat species, Diaemus youngi and Diphylla ecaudata, are rare and feed mainly on avian blood (Aguiar et al. 2006).There are few studies on bat ectoparasites and their relationship with their hosts in Brazil (Gettinger & Gribel 1989, Komeno & Linhares 1999 Graciolli et al. 2008). The purpose of this study was to investigate the degree of host specificity of the bat flies on vampire bat species in the cerrado of Central Brazil. Previous studies of ect...

Estado Do Conhecimento Da Fauna De Invertebrados Não-Marinhos Da Ilha Grande (Angra Dos Reis, Rj)

RESUMOA Ilha Grande, situada ao sul do Estado do Rio de Janeiro, possui importantes remanescentes de Floresta Atlântica. Entretanto, o conhecimento sobre sua fauna de invertebrados não-marinhos ainda é restrito, tanto em abrangência de grupos taxonômicos como em áreas geográficas. Devido à importância de inventários de biodiversidade para a conservação e tendo em vista a falta de informação organizada sobre os registros disponíveis, elaboramos uma lista dos táxons citados e suas respectivas localidades, utilizando dados primários de projetos em andamento e as fontes bibliográficas disponíveis. O resultado consiste em uma lista com 465 táxons de invertebrados não-marinhos, a grande maioria do Filo Arthropoda (72,9%) seguido do filo Mollusca (22,15%). Dos táxons citados 27,2% estão na categoria específica e 60% na categoria gênero. A análise dos dados mostrou que houve um incremento de informação a partir de 1999, e que essa informação está concentrada no entorno da Vila Dois Rios. Os resultados apresentados demonstram a necessidade de realização de inventários de fauna, com ampliação dos grupos taxonômicos e das áreas estudadas, no sentido de completar as imensas lacunas detectadas. Palavras-chave: Banco de dados; diversidade; Floresta Atlântica; lista faunística; Rio de Janeiro. ABSTRACT CURRENT KNOWLEDGE OF THE NON-MARINE INVERTEBRATES FAUNA OF ILHA GRANDE (ANGRA DOS REIS, RJ). Ilha Grande, a continental island located at Southern of Rio deJaneiro state, has important remnants of Atlantic Rainforest. However, the knowledge of the non-marine invertebrate fauna is not sufficiently well known, concerning not only taxonomic groups but also geographic areas. Considering the relevance of biodiversity inventories to conservation, allied to the absence of organized information about the existing data, we prepared a taxonomic list of the non-marine invertebrates reported to Ilha Grande, including distributional data, based on primary data of ongoing research projects and literature. The list is composed of 465 taxa of non-marine invertebrates, mainly Arthropoda (72.9%), followed by Mollusca (22.15%). Among cited taxa 25.52% are in the species category and 60% are in the genus category. The data analysis revealed an information increase since 1999 and that this information are concentrated at Vila Dois Rios region. Results show the need for improving Ilha Grande faunistic inventories, focusing taxonomic groups and areas, in order to fill the huge existing gaps.

“…Studies that analyze reinfestation can clarify this pattern of choice. In relation to bats, the studies by Esbérard et al (2005) and demonstrated the behavior of ectoparasites in laboratory experiments. Esbérard et al (2005) showed that the Streblidae species Megistopoda aranea (Coquillet, 1899), Megistopoda proxima (Séguy, 1926), and Strebla guajiro (Garcia & Casal, 1965) search for their hosts by species: Artibeus lituratus (Olfers, 1818), Sturnira lilium (E. Geoffroy, 1810) and Carollia perspicillata (Linnaeus, 1758), respectively.…”

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.
