Diversidade de Calliphoridae (Insecta: Diptera) na base de extração petrolífera da Bacia do Rio Urucu, na Amazônia brasileira. Acta Amazonica, Manaus, v. 40, n. 3, p. 579-583, set. 2010.

Acesso em:.1809-4392https://repositorio.ufpa.br/handle/2011/6327The 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.porAcesso AbertoCalliphoridaeMoscas varejeirasAbundânciaRiqueza de espéciesAmazôniaBlow fliesAbundanceRichnessAmazonArtigo de Periódicohttp://dx.doi.org/10.1590/S0044-59672010000300018
