From Penn State Extension
-Kathy Demchak & Dave Biddinger, Penn State University;
and Bryan Butler, University of Maryland

• Part 1: Overview and Identification 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. 
• Part 2: Natural History 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. 
• Part 3: Monitoring 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. 
• Part 4: Management Discusses cultural practices for minimizing populations, and chemical options that will provide effective control for growers of susceptible crops.
