Interpretive Summary: The invasive spotted wing drosophila fly is a major pest of soft fruits worldwide. This note extends the distribution of this species to a western state of Argentina, a massive range expansion for South America. As Argentina is major trading partner with the United States, this information is critical for future food safety. Also recorded are species of natural enemy wasps that kill spotted wing drosophila. Biological control workers, extension agents, and APHIS cooperators worldwide will find this research product essential for their own work.

Technical Abstract: The invasive Spotted Wing Drosophila (SWD), Drosophila suzukii Matsumura, is reported for the first time in La Rioja, Argentina. This represents a major range expansion for this species. The natural enemies of SWD, Leptopilina clavipes and Ganaspis hookeri were also collected with the SWD at the same time.
