Spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is an invasive pest that was introduced into Florida in 2009. Spotted wing drosophila survives well under Florida’s climatic conditions. In 2014, losses to berry crops in Florida were estimated at $35 million. Losses are due to maggot-infested fruit, which is unacceptable for the fresh berry market, and puncture holes in the fruit made by egg-laying females. The holes lead to secondary infection by fungal and bacterial pathogens. This 4-page fact sheet written by Lindsy E. Iglesias, James F. Price, Craig R. Roubos, Justin M. Renkema, and Oscar E. Liburd and published by the Department of Entomology and Nematology describes the flies and some strategies to identify them and manage them in berry operations.
Spotted wing drosophila (SWD) is a tiny invasive fruit fly pest of small fruits. It has been found infesting fruits in Europe and North and South America. Since its first capture in California in 2008, SWD has established populations throughout the United States in over 47 states. This trifold brochure written by Lindsy Iglesias, Teresia W. Nyoike, and Oscar E. Liburd and published by the Entomology and Nematology Department describes how to identify and monitor these tiny pests and explains a few strategies to control them and limit the damage they cause to fruit crops.
The spotted wing drosophila is a recently discovered invasive species native to parts of East Asia. It was first detected in the continental United States in California in 2008 and in Hillsborough County, Florida in 2009. Since then, the spotted wing drosophila has spread to over 28 counties in Florida. SWD is polyphagous, meaning it feeds on many different host plants, including most thin-skinned fruits. The major hosts of concern to the Florida agriculture industry are blueberries, strawberries, blackberries and grapes. This 5-page fact sheet was written by Oscar E. Liburd and Lindsy E. Iglesias, and published by the UF Department of Entomology and Nematology, June 2013.
Most Drosophila flies are associated with rotten or over-ripened fruits and are nuisance pests. However, a few species such as the spotted wing drosophila, D. suzukii (Matsumura), can infest un-ripened fruits and are of economic significance. First detected within the continental United States in August 2008, D. suzukii has become a serious threat to fruit crops. This 6-page fact sheet was written by Rajinder S. Mann and Lukasz L. Stelinski, and published by the UF Department of Entomology and Nematology, May 2011.
