No. of bitstreams: 1 Dissertação - Emanuelle de Sousa Farias.pdf: 2780340 bytes, checksum: bac6d0e67ce460607bfe6e587aa2068a (MD5) Previous issue date: 2014-02-26 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The biting midges Culicoides are vectors of some etiological agents to humans and other mammals. There are just a few studies in Amazon basin about that insects and the diversity and richness of this genus is underestimated. The aims of this study were to describe the fauna of midges in a rural settlement in Amazon and to understand how the anthropic effects may affect the richness and abundance of these putative local vectors. Collections were done by CDC light traps in some environment as primary forest, forest borders, secondary forest, fruit garden and peridomiciliary area with animal shelters. We identified 6.093 individuals, distributed in 42 species, 39 morphotypes of seven subgenera and /or species groups and five new species of Reticulatus group. We found 13 new occurrence to Amazonas State C. aldomani, C. batesi, C. brownie, C. debilipalpis, C. flavivenula , C. franklini, C. glabellus, C. guamai, C. guttatus, C. ocumarensi, C. paramaruim, C. pusilloides and C. tidwelli, and two new occourence to the country, the species C. brownie and C. tidwelli. Our results show that different anthropic levels affect the abundance and diversity of midges. The diversity was high in less anthropized environments. The peridomiciliary areas had a high richness and abundance of Culicoides. / Os Culicoides são insetos transmissores de agentes patogênicos ao homem e outros animais. Na região amazônica existem poucos estudos sobre esses insetos e o número de espécies é subestimado. Este estudo objetivou conhecer a fauna de Culicoides de um assentamento rural na Amazônia e verificar se o efeito antrópico afeta a diversidade e abundância dos mesmos. As coletas foram feitas com armadilhas luminosas do tipo CDC em ambientes de floresta, borda de floresta, capoeira e peridomicílio. Foram identificados 6.093 indivíduos, distribuídos em 42 espécies, 39 morfótipos de sete subgênero/grupo e cinco espécies novas do grupo Reticulatus. Foram encontrados 13 novos registros de espécies de Culicoides para o estado do Amazonas: C. aldomani, C. batesi, C. brownie, C. debilipalpis, C. flavivenula , C. franklini, C. glabellus, C. guamai, C. guttatus, C. ocumarensi, C. paramaruim, C. pusilloides e C. tidwelli, sendo C. brownie e C. tidwelli novos registros para o Brasil. Os resultados indicam que diferentes graus de antropização do ambiente influenciaram a abundância e diversidade dos Culicoides, cuja diversidade foi alta em ambientes menos antropizados. Ambientes totalmente antropizados, como peridomicílio, apresentaram maior abundância e riqueza.
