Interpretive Summary: The ‘Biological Control: A Guide to Natural Enemies in North America’ is a website providing up-to-date information on important natural enemies for biological control of various serious pests in North America. The spotted-wing drosophila fly is native to eastern Asia but has also become widely established in the Americas and Europe, and part of Africa, where it has become the most serious pest of berries and other small fruits. A parasitic wasp that is the fly’s major natural enemy in Asia has been approved for introduction and field release in the US after quarantine evaluations. At this website, we provide descriptions of this biological control agent. The information will be useful for stakeholders for effective use of this natural enemy for the management of this invasive pest.

Technical Abstract: Drosophila suzukii Matsumura (Diptera: Drosophilidae) is native to eastern Asia but has established widely in the Americas and Europe, and part of Africa, where it is a pest of numerous fruit crops. As part of a classical biological control program, one larval D. suzukii parasitoid, Ganaspis brasiliensis Ihering (Hymenoptera: Figitidae) has been introduced from Asia and approved for field release in North America after quarantine evaluation for the parasitoid's safety and effectiveness. The ‘New York State Integrated Pest Management Outreach & Education” is a website providing up-to-date information on important natural enemies for biological control of various serious pests in North America. Here, we provide descriptions of this important biological control agent for D. suzukii. This guide includes images of both D. suzukii and G. brasiliensis, descriptions of their life cycles and habits, and other useful information about this parasitoid. We hope this information will be useful for stakeholders to effectively use this biocontrol agent for the management of this invasive pest.
