Spotted Wing Drosophila Fact Sheets Completed and Online

Posted: August 8, 2012

Thanks to receiving funding from the Northeast Integrated Pest Management (NE-IPM) Center, we were able to complete a set of four full-color fact sheets on spotted wing drosophila (SWD), and they are now available online. These fact sheets were written with northeastern United States growers of the most susceptible crops (raspberries, blackberries, day-neutral strawberries, and cherries) in mind.    

"Spotted Wing Drosophila, Part 1: Overview and Identification" is available at and briefly summarizes the concern surrounding spotted wing drosophila. The fact sheet contains photographs that illustrate in detail the differences between SWD adults and other local fruit fly species that could be mistaken for SWD. "Spotted Wing Drosophila, Part 2: Natural History" is available at < >. This fact sheet discusses the life cycle of SWD in detail, along with explaining how environmental conditions and nearby crops can affect presence and numbers of SWD. "Spotted Wing Drosophila, Part 3: Monitoring," at covers how to monitor for SWD adults in fields, and SWD larvae in fruit. The fact sheet also provides details on how to store and ship samples should identification from others be needed. "Spotted Wing Drosophila, Part 4: Management" at discusses cultural practices for minimizing populations, and chemical options that will provide effective control for growers of susceptible crops.
