High abundance of neotropical drosophilids (Diptera: Drosophilidae) in four cultivated areas of central Brazil.

摘要: The drosophilid assemblages of four cultivated areas (soy, bean, corn, and orange plantations) grown in the core Neotropical region were analyzed by comparing their abundances compositions. collections, which gathered using 38 banana traps, captured 12,560 drosophilids, including nine six exotic species. Most flies collected bean (43%) soy (42%) fields. composition relative abundance species also varied among areas, with orchards presenting highest exotics due to dominance Afrotropical Zaprionus indianus (Gupta). Crop plantations dominated a species, Drosophila cardini (Sturtevant), has been shown be well adapted dry disturbed environments. We discuss them from neighbor urban natural low richness found this study is similar environments lower than forests, supporting pattern already known for other taxa. high drosophilids as (D. cardini) crop assemblages, was surprising result.
