Interpretive Summary: During the last 10 years, dozens of university, government, and industry scientists have collaborated in response to the invasion crisis caused by the accidental introduction of Drosophila suzukii, Spotted-wing drosophila (SWD), into the United States. This review article presents an up-to-date overview of the current integrated pest management approaches to strategically reduce the economic impacts of this pest on U.S. berry agriculture, where it is a major pest of raspberries, blackberries, blueberries, cherries, and occasionally strawberries. It includes information about monitoring technology, chemical, biological, and behavioral control options, and cultural practices including the efficacy of pruning, mulching, sanitation, physical exclusion, and post- harvest refrigeration. The article also discusses the seasonal biology of SWD as it relates to management, management economics, and the use of predictive modeling to enhance our understanding of yearly population dynamics.

Technical Abstract: Drosophila suzukii Matsumura (Diptera: Drosophilidae) also known as spotted-wing drosophila (SWD), is native to southeast Asia. SWD is one of the most challenging insect pests to manage since its invasion into key international production regions starting during 2008. All available integrated pest techniques need to be investigated in an attempt to keep insect pest populations below an economic threshold within economically valuable crops. SWD has expanded its range to affect all major European and American fruit production regions. Infestations of SWD generate direct and indirect economic impacts through yield losses and, shorter shelf life of infested fruit. Direct costs have significantly increased because of, monitoring, and treatments, but also because of increased post-harvest management. SWD infestations have in some cases resulted in rejections due crop quality and maximum pesticide residue levels. It has also resulted in the closure of some international markets. Organic production of susceptible fruit has been particularly severe, mainly because of limited effective control tools. SWD is a highly adaptive insect, able to disperse and survive and flourish in a range of environmental conditions. It is this capability that ultimately is believed to result in the severe economic impacts experienced by producers. This review attempts to evaluate some of the most promising methods studied as part of an integrated SWD control strategy across the world. We attempt to present the effectiveness, impact, sustainability and the stage of development of each of these current techniques.
