    Califorídeos (Diptera, Oestroidea) associados a cadáveres suínos em uma área de cerrado na Reserva Ecológica do Inhamum, Caxias, Maranhão, Brasil: subsídios para aplicação em processos forenses
    (Universidade Federal do Pará, 2012-05-22) SILVA, José Orlando de Almeida; ESPOSITO, Maria Cristina; http://lattes.cnpq.br/2112497575917273
    The objective of this study was to determine the fauna and the pattern in the temporal distribution of blow flies collected visting or reared from pig carcasses in a cerrado area at the Reserva Ecológica do Inhamum (REI), Caxias, MA. Two experiments were performed, one in the dry season (July and August of 2010) and the another in the rainy season (March and April of 2011). In each experiment three pig carcasses weighing 12 kg each were utilized. The carcasses were placed inside wire metal cages to prevent the access of large scavengers. A suspended trap was placed above each cage to capture adult blow flies that visited the pig carcass. Trays containing sawdust were placed under the cages in order to collect larvae leaving the carcass for pupation. A total of 51,234 specimens was collected. Of these, 25,093 adults were collected in the suspended traps and 26,141 adults were reared from the carcasses. The following species were identified: Chloroprocta idioidea (Robineau-Desvoidy, 1830) Chrysomya albiceps (Wiedemann, 1819), Chrysomya megacephala (Fabricius, 1794), Chrysomya rufifacies (Macquart, 1843), Cochliomyia macellaria (Fabricius, 1775), Hemilucilia benoisti Séguy, 1925, Hemilucilia segmentaria (Fabricius, 1805), Hemilucilia townsendi Shannon, 1926, Lucilia eximia (Wiedemann, 1818) and Lucilia sp1. Chrysomya rufifacies and H. townsendi are new records for Brazil. Cochliomyia macellaria and C. idioidea were the most abundant among the adults collected in traps, and C. albiceps and C. rufifacies were most abundant among reared specimens. The species of Hemilucilia were the only ones not reared from the carcasses. The mean time of decomposition of the pig carcasses was 10 days, and there was no difference between carcasses exposed in dry and rainy seasons. In adition, the duration of each decomposition stage did not vary between the two seasons. The duration of the stages was different, and the fermentation stage was the longest. Lucilia eximia, C. idioidea and C. macellaria, collected in the traps, were the pioneers in colonizing the pig carcasses, and they were found in all stages of decomposition. However, only L. eximia showed an association with the Initial stage, according to the IndVal index. The larvae of L. eximia were the first to leave the carcasses for pupation, followed by C. macellaria, C. albiceps and C. rufifacies. According to the IndVal index, the adults of H. townsendi and H. benoisti collected in the traps, were the only species that showed an association with only one stage, the Bloated stage. Chrysomya rufifacies and C. megacephala showed an association with the Black Putrefaction and Fermentation stages. The other species showed an association with four stages. With respect to species reared from carcasses, L. eximia and C. macellaria were the only ones that showed an association with the Bloat stage, and C. rufifacies and C. albiceps were the only species that had an association with the Dry Decay stage. The abundance values of L. eximia, C. idioidea, C. macellaria, C. albiceps, and C. rufifacies, collected in the traps, were different between the stages of decomposition, and the Black Putrefaction was the more attractive to these species. The abundance values of C. albiceps, C. rufifacies, and L. eximia, reared from the carcasses, were different between the stages, and the Dry Decay and Black Putrefaction stages showed the higher abundance of Chrysomya species and L. eximia, respectively. The species of L. eximia and C. idioidea, collected in the traps, and reared specimens of C. rufifacies were more abundant in the rainy season. With respect to the specimens collected in the traps, the ordination analyses showed that the community of blow flies has higher similarity between the Black Putrefaction, Fermentation and Dry Decay stages, due to higher richness and abundance values. However, with respect to the reared species, the community of the Fermentation and Dry Decay stages were the most similar. These results contribute to understanding the successional process of visitors adults and reared larvae of blow flies during the decomposition of pig carcasses in a cerrado area of the state of Maranhão.

    Diversidade de Calliphoridae (Insecta: Diptera) na base de extração petrolífera da Bacia do Rio Urucu, na Amazônia brasileira
    (Instituto Nacional de Pesquisas da Amazônia, 2010-09) ESPOSITO, Maria Cristina; SOUSA, José Roberto Pereira de; CARVALHO FILHO, Fernando da Silva
    The diversity and abundance of blow flies in three environments (anthropic gaps, tree-fall gaps, and primary "terra firme" forest) of Porto Urucu/AM were evaluated in annual collects realized in 2004, 2005, and 2006. During these three years were collected 2,121 specimens belonging to 14 species. The most abundant species were Chloroprocta idioidea (Robineau- Desvoidy), Eumesembrinella randa (Walker), and Hemilucilia semidiaphana (Rondani). Primary forests and tree-fall gaps enviroments, showed higher blow flies abundance than anthropic gaps, with diversity and equitability index higher than anthropic gaps, when the dominance value was high.

    A fauna de califorídeos e sarcofagídeos (Insecta, Diptera) das matas e clareiras com diferentes coberturas vegetais da base de extração petrolífera, Bacia do Rio Urucu, Coari, Amazonas
    (Universidade Federal do Pará, 2008-07-21) SOUSA, José Roberto Pereira de; ESPOSITO, Maria Cristina; http://lattes.cnpq.br/2112497575917273
    This research was done at the oil extraction field of Urucu River in Coari, Amazonas, during the months of April, June and October of 2007, in 16 areas, 12 of them forest clearings and four forests, arranged in four environments (C1,C2,C3 and MT) according to type of forest cover. The objective was to study the composition, abundance, wealth, and diversity of Calliphoridae e Sarcophagidae (Insecta, Diptera) and also assess the possibility of these taxons to be used as parameters for evaluation of the condition of vegetal recuperation in clearing areas. The number of calliphorid collected were 7.215 (three subfamilies, eight genera and 16 species), being Chloroprocta idioidea (Robineau-Desvoidy,1830) (88,06%) and Paralucilia adespota Dear,1985 (4,35%) the most abundant species. The patterns of calliphorid abundance did not differ among the environments, however the e distinctive in relation to the estimated richness and diversity, forming two groups (C1-C2) and (C3-MT). The ordination analysis (non-metric multidimensional scaling) showed that the environment differed among themselves, as well as a greater similarity between C1-C2 and C3-MT, in relation to the structure of calliphorid communities. From the Sarcophagidae family 3.547 species were collected, distributed in 10 genera, six subgenera and 23 species , being Sarcodexia lambens (Wiedemann,1830) (47,05%) and Peckia (Peckia) chrysostoma (Wiedemann,1830) (19,11%), the most abundant species. The patterns of abundance, estimated richness and diversity for this family differed among environments and separated them into two groups, one from the clearings (C1,C2 and C3) and the other from the forest (MT). The ordination analysis (non-metric multidimensional scaling) showed a separation between sarcophagid fauna from clearings and those from the forests. The canopy cover influenced the pattern of abundance of Eumesembrinella randa Sarcophagidae family, only the abundance of Peckia (Pattonella) intermutans species (Walker,1861) was greater on environments with higher rates of forest canopy. The abundance of Oxysarcodexia amorosa (Schiner,1868), O. fringidea (Curran & Walley,1934), O. thornax (Walker,1849), P. (P.) chrysostoma and S. lambens species presented a negative linear relation with the forest canopy. These results indicate the possibility for use of these patterns as parameters to assess change in the vegetation structure.
