Estudos sobre a fauna de Sarcophagidae (Diptera) de Belo Horizonte - Minas Gerais. I- Levantamento taxonômico e Sinantrópico

Abstract

Com o objetivo de se conhecer a fauna de Sarcophagidae da região de Belo Horizonte, Minas Gerais, e se obter dados sobre seu comportamento, foram realizadas capturas sistemáticas em três áreas ecologicamente distintas, pelo período de um ano (maio de 1980 a abril de 1981). Para as capturas, foram utilizadas dois tipos de armadilhas apropriadas e cinco tipos de iscas; peixe cru, carcaça de camundongo, v´sceras de galinha, banana amassada com rapadura e fezes humanas. Foi capturado um total de 10.097 espécimens, dos quais foram estudados 9.582 exemplares, representados por 25 espécies. O índice de sinantropia foi determinado segundo a metodologia de Nuorteva (1963). Foram obtidos índices variáveis de sinantropia para as 25 espécies analisadas, sendo as mais sinantrópicas Parasarcophaga ruficornis (IS = + 94,7) e Bercaea haemorrhoidalis (IS = + 84,3), e as mais assinantrópicas Euboettcheria florencioi (IS = - 98,8) e Oxysarcodexia augusta (IS = - 96,9).<br>Over a period of one year (May, 1980 to April, 1981), systematic collections of Sarcophagidae were made in three ecologically distinct areas of Belo Horizonte, Minas Gerais. Two types of traps and five types of bait were used: raw fish, carcasses of mice, viscera of chickens, banana mashed with sugar, and human faeces. Of the total of 10,097 specimens captured, the 9,582 studied included 25 species. Indices of synanthropy (I.S.) for the 25 species varied considerably. The most synanthropic were Parasarcophaga ruficornis (I.S. = + 94.7) and Bercaea haemorrhoidalis (I.S. = + 84.3), and the least were Euboettcheria florencioi (I.S. = - 98.8) and Oxysarcodexia augusta (I.S. = - 96.9)

Composition, Abundance and Richness of Sarcophagidae (Diptera: Oestroidea) in Forests and Forest Gaps with Different Vegetation Cover

“…This may be related to the ample capacity of adaptation to the human-modi ied environments shown by lesh lies, even becoming dependent on them. The eusynanthropic characteristic of some species of this family has been already recorded (Linhares 1981, Dias et al 1984a, D' Almeida 1984.…”

“…The family Sarcophagidae shows different degrees of synanthropy, with some species that live only in natural environments and others that are adapted to live in the human environment, and some species even depend on this kind of enviroment (Linhares 1981, Dias et al 1984a, D' Almeida 1984. This situation and the rapid population responses suggest the possibility that patterns of abundance and richness of Sarcophagidae could be used as indicators of anthropic interference on natural environments.…”

Sinantropía de Sarcophagidae (Diptera) en La Pintada, Antioquia-Colombia

“…The transformation of natural environments into urban and rural areas, radically changes local fauna and flora, however, some species of flies can adapt to these new conditions; this association is called synanthropy and can be calculated for different ecological regions according to the formula proposed by Nuorteva (Ferreira 1979, Linhares 1981, Dias et al 1984, D'Almeida 1984, Ferreira & Lacerda 1993, Gomes & Von Zuben 2005, Montoya et al 2009, Uribe et al 2010, who considers synanthropy as "the capacity of some animals to make use of favorable conditions created by men" (Nuorteva 1963). …”

“…Sarcophagidae are an important component of synanthropic fauna in South America, however, there are few works done under this perspective, which have been developed mainly in some regions of Brazil as Curitiba (Ferreira 1979), Campinas (Linhares 1981), Belo Horizonte (Dias et al 1984), Rio de Janeiro (D'Almeida 1984) and Goiânia (Ferreira & Lacerda 1993). In Colombia, there are only two studies on synanthropy, one for the family Calliphoridae (Montoya et al 2009) and another for Muscidae (Uribe et al 2010) with none on Sarcophagidae associated to anthropic environments.…”

“…Para efetuar esta pesquisa, utilizaram-se algumas das espécies que obtiveram altos índices de sinantropia, em trabalhos efetuados no Brasil, portanto, insetos de importância sanitária (Ferreira 1978, Linhares 1979, d' Almeida 1983, Dias et al 1984.…”
