Zulkibar Bot fly; myiasis; opossum; parasitism. On the other hand, females may increase their home range areas to found more food due to increase energetic requirements associated with pregnancy and lactation that may increase their probabilities of being infested for parasites Krasnov et al. Bot flies of the genus Cuterebra are restricted to the New World and are distributed throughout most of the temperate and tropical areas. Their larvae are obligatory parasites of mammals, producing myiasis in dermic and subdermic tissues of these animals Catts ; Pape This present study suggests an expansion of C.

The prevalence of bot flies larvae parasitism in warm-wet season was 0. Canadian Journal of Zoology There is almost 70 species of Cuterebra and these flies are one of the most highly studied groups of insect parasites of New World wild mammals Slansky These studies have showed higher prevalence of bot fly larval parasitism in warm-wet season of the year, although few longitudinal studies demonstrate that such flies may be multivoltine Bergallo et al.
The neotropical oestrids bot flies seem to be multivoltine, but the season of the peak of reproductive activity varies widely between the regions. The gracile mouse opossum Gracilinanus microtarsus Wagner, is a small gsolitary, arboreal, nocturnal, and insectivorous marsupial commonly found in the Atlantic rainforest and forested physiognomies interspersed in savannas in the Cerrado biome.
There was a problem providing the content you requested Males and females may differ in prevalence of parasites due to fundamental biological differences between sexes. Journal of Wildlife Diseases After emergence the pupae were maintained buried in moist sand in gauzed-covered glass cups at ambient temperature until adult flies emerged pupariation lasted 30 to 32 days.
Sex-biased parasitism, seasonality and sexual size dimorphism in desert rodents. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. Trends in Parasitology Thus, the prevalence in each season was estimated by the number of times that one individual became infested for parasites. Some parasitized individuals were kept at the laboratory to allow natural emergence of the bot flies larvae.
The prevalence of Cuterebra simulans bot fly parasitism on marsupial Gracilinanus microtarsus was compared between sexes and seasons of the year. Cricetidae and Metachirus nudicaudatus Marsupialia: The prevalence of bot flies larvae parasitism in females was 0.
Services on Demand Journal. Therefore, other factors related to the biology of the oestrids bot flies may explain our results. This pattern agree with observations of others studies with oestrids flies in southern Neotropical areas, suggesting the occurrence of latitudinal change in the peak of bot flies reproductive activity related to seasons of the year along these systems.
Seasonality in reproduction, age structure and density of the gracile mouse opossum Gracilinanus microtarsus Marsupialia: Quarterly Review of Biology No significant difference was observed between females and males but prevalence was higher in warm-wet season than cool-dry season. Our results did not show differences in the parasitism prevalence of the C.
Oestridae infesting a neotropical forest rodent, Proechimys semispinosus Rodentia: Second, famklia of the Oestrid family undergo long periods of association with their natural hosts and have evolved lestridae complexity of the mechanisms by which larvae down regulate host immune system Otranto ; Stevens et al.
Journal of Tropical Ecology Effects of bot fly Alouattamyia baeri parasitism on free-ranging howler monkey Alouatta palliata population in Panama. In the Neotropical region, the studies concerning the prevalence and dynamics of bot fly larval parasitism in wild mammals are scarce and have been carried out mainly with rodents. Since the studies in the Neotropical have showed high seasonality in the prevalence of parasitism by Cuterebra larvae and that biological differences between hosts sexes may affect parasitism, the aim of our study was to investigate the differential prevalence of the bot flies larvae parasitism between sexes and seasons of the year on G.
Biology of New World bot flies: Biostatistical analysis4th ed. Mammals of the NeotropicsVol. Bot fly; myiasis; opossum; parasitism. The effect of botfly parasitism of Metacuterebra apicalis Diptera on reproduction, survival and general health of Oryzomys russatus Rodentiain southeastern Brazil.
On the other hand, females may increase their home range areas to found more food due to increase energetic requirements associated with pregnancy and lactation that may increase their probabilities of being infested for parasites Krasnov et al.
This species shows sexual size dimorphism with adult males being larger than adult females, and has a markedly seasonal pattern of reproduction tamilia in the warm-wet season when males competing for access to females Costa et al.
We set an 11 x 11 trapping grid with trapping-stations located 15 m from ostridae other. However, the knowledge available on the ecology and natural history of most species comes from studies carried out in temperate regions e.
The only knowledge about this fly species was restricted to its oesrridae, type-localities and respective original hosts. Notes on the hosts of neotropical cuterebrini Diptera: We captured 78 individuals of the G.
Cuterebridae infection in Ototylomys phyllotis Rodentia: Their larvae are obligatory parasites of mammals, producing myiasis in dermic and subdermic tissues of these animals Catts ; Pape We visually examined all the oeestridae to record the occurrence or absence of the bot flies larvae parasitism and the number of the larvae in each host.

Mikabar We need you! The number of the bot flies larvae in each host varied of 1 to 5. Thus, seem to occur a latitudinal change in the peak of bot flies reproductive activity related to the seasons along these systems but more studies are necessary to reinforce or to refute this hypothesis. Seasonality in reproduction, age structure and density of the gracile famolia opossum Gracilinanus microtarsus Marsupialia: Myiasis in man and animals in the Neotropical region.
