Interpretive Summary: Effective monitoring methods are essential to manage spotted wing drosophila (SWD). In areas where SWD has recently invaded, monitoring is needed to detect whether it is present and know the areas of infestation. In areas where SWD has established, monitoring tools are used to capture the first overwintering flies, track seasonal biology, assess effects of management tactics. Most research has focused on the development of adult SWD trapping devices and attractants, while larval monitoring has been mainly used in post-harvest evaluations. In this chapter, we will summarize current research on adult SWD traps, chemical ecology as it relates to efforts to improve attractants, seasonal and daily activity patterns as detected in monitoring traps, crop effects on adult monitoring, and larval sampling methods and implications.

Technical Abstract: Effective monitoring methods are essential to the management of both invasive and established Drosophila suzukii populations. In the case of invading populations, tools are needed to detect initial introductions and to delineate infested areas. For established populations, monitoring tools which can capture the first overwintering flies, track seasonal biology, assess effects of management tactics, and provide guidance for marketing fruit are necessary. The development of adult D. suzukii traps and attractants has been the focus of significant research efforts while larval sampling and monitoring efforts have been largely focused on post harvest evaluation of fruit crops. In this chapter, we will summarize current research on adult D. suzukii traps, chemical ecology as it relates to efforts to improve attractants, seasonal and daily activity patterns as detected in monitoring traps, crop effects on adult monitoring, and larval sampling methods and implications.
