Similaridade na composição de espécies no espaço das coletas de imaturos dos Calliphoridae (Diptera, Brachycera) colonizadores de modelos natimortos de Sus scrofa L. (Suidae), em dois ambientes distintos, no Acre, Brasil

Resumo. A ecologia da decomposicao de cadaveres nao havia ainda sido estudada no Estado do Acre. Este estudo foi realizado em dois ambientes, Floresta e Pasto, entre 21 de dezembro de 2016 e 03 de marco de 2017, e usou oito individuos de Sus scrofa L. natimortos como iscas para os imaturos de Calliphoridae colonizadores. Foram observados cinco estagios de decomposicao (fresco, inchado, decomposicao ativa, decomposicao avancada e restos) em todas as carcacas. Foram identificadas, na Mata, Chrysomya albiceps (Wiedemann), Hemilucilia segmentaria (Fabricius), Hemilucilia semidiaphana (Rondani) e Lucilia eximia (Wiedemann); e, no Pasto, Ch. albiceps , Cochliomyia macellaria (Fabricius), H. segmentaria e L. eximia . H. segmentaria foi presente em todo o processo de decomposicao no ambiente de Mata. Ch. albiceps e L. eximia foram presentes em todo o processo de decomposicao no ambiente de Pasto. No Estado do Acre, as pesquisas em ecologia da decomposicao se iniciam com este estudo, o qual demonstrou estar presentes na regiao, pelo menos, algumas especies amplamente distribuidas no Brasil, com poucas diferencas entre ambientes. Similarity in the species composition in the space of immature collections of Calliphoridae (Diptera, Brachycera) colonizers of stillborn models of Sus scrofa L. (Suidae), in two distinct environments, in Acre, Brazil Abstract . The ecology of corpse decomposition (carrion ecology) had never before been studied at State of Acre. This study was carried out within two different environments, Forest and Pasture, from December 21th of 2016 to March 03rd of 2017. Eight stillbirth individuals of Sus scrofa L. were observed, intentionally placed as trap to be hosted by Calliphoridae offspring. It was observed in all decomposing carrion, five stages of decomposition (fresh, bloated, active decay, advanced decay and remains). In the Forest were identified Chrysomya albiceps (Wiedemann), Hemilucilia segmentaria (Fabricius), Hemilucilia semidiaphana (Rondani) and Lucilia eximia (Wiedemann); and in the Pasture Ch. albiceps , Cochliomyia macellaria (Fabricius), H. segmentaria and L. eximia . H. segmentaria has been present in the whole process of decomposition into the Forest environment. Ch. albiceps and L. eximia were observed all the stages while decomposition has been taken in Pasture. In the State of Acre, research about carrion ecology starts from this study beginning, which has demonstrated being present at this region, at least, some species widely distributed in Brazil, with few differences observed between the two studied environments.
