Interpretive Summary:

Technical Abstract: The spotted wing drosophila has become a major cherry pest in California. To develop sustainable management options for this highly mobile pest, we worked with cooperators at Oregon State University and the USDA to discover and import natural enemies of the fly from its native range in South Korea and China that could be suitable for release in the USA. We found several larval parasitoids that readily attack the fly in UC Berkeley quarantine evaluations. During 2016 we submitted petitions, which are pending with regulatory agencies, for field release of two promising candidate natural enemies, Leptopilina japonica and Ganaspis brasiliensis.
