Zaprionus tuberculatus (Diptera, Drosophilidae): A generalist species that deserves attention

The Drosophilid family comprises over 4000 species, with several species posing potential threats to agriculture, as identified by the European and Mediterranean Plant Protection Organisation (EPPO). Among these species, Drosophila suzukii, Zaprionus tuberculatus and Z. indianus have received attention due to their geographic expansion and potential risks to crops. This research aims to consolidate global data on Z. tuberculatus hosts, with a specific focus on this species' presence in Brazil's Federal District, its first reported location in the Americas. Reviewing existing literature and conducting fieldwork, we identified 61 plant species from 25 botanical families as potential hosts for Z. tuberculatus worldwide, from which 23 species are new hosts. It was noted that Z. tuberculatus had a high density on certain fruits, raising concerns about its potential as a pest. The presence of Z. tuberculatus alongside other pest species, such as Z. indianus and Drosophila suzukii, highlights the complexity of invasive species' interactions and their ecological impacts. These findings emphasize the need for standardized methodologies to evaluate invasive drosophilids' ecological and economic implications, enabling informed management strategies to mitigate their adverse effects on agriculture and ecosystems.
