The composition and potential hosts of mycophagous Drosophilidae from a section of the Brazilian Amazon forest in the Caxiuanã National forest were investigated. Sampling was performed in three different periods at long the wet season (January (beginning) and July (end) 2013 and May (middle) 2014). The samples were collected from existing trails by actively searching for fungal fruiting bodies where Drosophilidae were present. We present composition and richness analysis over two years of sampling sampling Drosophilidae and Fungi. We evaluate sampling completeness using asymptotic species richness estimators. Out of 159 fruiting body samples and 64 fungal species, 5,124 drosophilids belonging to 55 species and 5 genera were collected. The mycophagous Drosophilidae richness values estimated by Jackknife 1 and Bootstrap were 69 and 61, respectively. The estimated fly richness correlated positively with fungal richness and abundance. Among the Drosophilidae species identified in this study, approximately 5% represent new occurrences for Brazil and 56% represent new species. Four genera belonging to the Zygothrica genus group are found in the Amazon region, and these genera represent 80% of the fungus-associated fauna known to date for the tropics. In conclusion, our results show that the fungal richness and abundance were the factors that determined the high diversity of mycophagous Drosophilidae

Variação espacial e temporal de algumas espécies e grupos de Drosophila (Diptera) em duas reservas de matas isoladas, nas vizinhanças de Manaus (Amazonas, Brasil).

Coletas de Drosophila foram feitas com iscas em duas ilhas de floresta primária, nas proximidades de Manaus (Amazonas, Brasil) e na região recém-desmatada que lhes é circunvizinha. Algumas das espécies foram predominantes em um ou outro tipo de ambiente. locais com diferentes graus de perturbação por desmatamento apresentaram-se distintos com relação à oredem de abundância das espécies mais frequentes. As alterações na abundância das espécies ao longo do tempo foram irregulares especialmente em áreas perturbadas e não mostraram relação direta com as alterações sazonias (chuva e seca). Algumas das espécies mais frequentes demonstraram variação independente em abundância sugerindo respostas diferenciais às condições ambientais
