“…Prior to the present records, D. nasuta occupied 2.5 million km 2 in Brazil (Medeiros et al 2022). With the new locations of occurrence reported here, the area of occupation of the species has increased by 84%, corresponding to more than half of the country in approximately ten years of invasion.…”

“…A niche modeling study projected the expansion of the geographic distribution of D. nasuta in the Amazon Forest and Pantanal wetlands (Garcia et al 2022), which was also reported in the present study. Among the locations monitored here, D. nasuta had the highest relative abundance in the Amazon Forest (6.2%), representing a nearly fivefold increase since it was first recorded in this biome in 2017 (1.3%) (Medeiros et al 2022). These results demonstrate the adaptive success of the species in the Amazon Forest and the importance of the continuation of its monitoring in the area.…”

As a result of human activities and natural dispersal, exotic species can be brought to new areas, where they become established and spread, becoming invaders.These species are responsible for the loss of biodiversity and cause ecosystemic harm throughout the world. In this paper, we report the rapid, broad geographic expansion of the invasive fly Drosophila nasuta in Brazil. An 84% increase was found in its area of occupation in the country compared to previous studies. The present data reveal its arrival to the Pantanal wetlands in a location more than one thousand kilometers from the closest previous record in the Cerrado biome. We present the first record of D. nasuta in the Atlantic Forest in the states of Paraíba and Bahia. We report its introduction in the Amazon Forest in the state of Amazonas approximately 700 kilometers from previous records. The relative abundance of D. nasuta in this biome increased fivefold in comparison to a previous study. In the first decade of invasion in Brazil, D. nasuta has already colonized more than half of the country. The present data reveal its invasive potential and underscore the importance of following up the possible negative effects of this biological invasion.

“…The species D. nasuta and D. sturtevanti , classified as from both sites, have different biological and ecological aspects. D. nasuta is an exotic species, recently introduced in Brazil (first record in 2013, Leão et al 2017; Silva et al 2020), and first recorded in the Amazon in 2017 (from de de Medeiros et al 2022). Its invasive potential causes concern to native species, as this species has a high reproductive capacity and can use a great diversity of habitats and resources (Silva et al 2020; Montes et al 2021).…”

To mitigate the impacts of deforestation, Brazilian legislation requires the implementation of a Degraded Area Recovery Plan (PRAD). One way to assess the recovery of these areas is using bioindicators. This research tested the use of the drosophilid community structure as an indicator to evaluate post‐mining area restoration. We compared two regeneration techniques within the same chronological sequence and as reference used the forest remnants within the exploration area. The study was conducted in the municipality of Paragominas—Pará, in areas managed by Hydro mining company. Five sites of forest remnants were selected, five in natural regeneration and five in the nucleation technique, the latter two making up the PRADs. A total of 5,919 male drosophilids were collected belonging to 10 genera, and 32 species. Rarefaction showed the curves of the PRADs to be more asymptotic, than forested areas. Forest areas are potentially richer and, on average, have lower abundances and lower diversity. Beta diversity components in the forest present greater turnover and less nestedness processes when compared to PRADs areas. The PRADs showed no differences between them for any of the analyzed patterns. D. nasuta and D. sturtevanti behaved as generalists in relation to habitats, D. paulistorum and D. willistoni as forest specialists. D. malerkotliana, D. simulans, Scaptodrosophila latifasciaeformis, and Zaprionus indianus behaved as specialists in PRADs areas. The structure of the drosophilid community varied according to the environment, proving to be a good indicator for forest and regenerating environments, but it did not detect differences between the PRADs environments in early regeneration (6 years).

Although drosophilids have been extensively studied in laboratories worldwide, their ecology is still relatively poorly understood. This is unfortunate because some species are currently expanding their geographic distribution and infesting fruit crops. Here, we investigated the relationship between drosophilids and potential plant hosts in a commercial fruit and vegetable distribution center in the Neotropical region. We collected discarded fruits and vegetables from this commercial center during two time periods (2007–2008 and 2017–2018). Resources were weighted and individually monitored in the laboratory. The drosophilids that emerged were identified, and the relationship between them and their resources was explored. From the 99,478 kg of potential hosts collected, we identified 48 plant taxa, from which 48,894 drosophilids of 16 species emerged. On both collecting occasions, drosophilid assemblages were strongly dominated by basically the same exotic species, which explore a broader range of resources, especially those of exotic origin, when compared to neotropical drosophilids. These results are concerning because the studied site, Along with other urban markets around the world, might be acting as sources of generalist widespread species that disperse to surrounding natural vegetation and contribute to biotic homogenization.
