IPM program development for an invasive pest: coordination, outreach and evaluation

Abstract

BACKGROUND: Spotted wing drosophila (SWD), Drosophila suzukii Matsumura, was found along the west coast of the United States, beginning in 2008 and 2009, infesting a wide variety of small and stone fruit crops. This pest is a serious economic threat, as noted in its native range (Asia), because it lays eggs within ripening fruit before harvest, leading to crop loss. The aim of this paper is to describe the process in order to create collaboration, communication routes and evaluation methods in response to a new invasive pest. RESULTS: Funding was secured and a program (SWD*IPM) was quickly developed to address social, economic and biological components. Communication routes were outlined, and a stakeholder advisory panel was established to guide program objectives. A central website was created to host up-to-date information. An online monitoring and mapping program for D. suzukii in Oregon fruit-growing regions illustrated the range, distribution and seasonal abundance of the pest. In addition, a program for backyard fruit growers was initiated to examine citizen scientists' roles in managing D. suzukii infestations in the urban setting. A monitoring kit, laminated educational cards, dry fly mounts and quick-time videos were some of the tools used to educate growers. First-year challenges for dealing with a new pest are discussed. CONCLUSION: The discovery and subsequent response to an exotic pest is information intensive and requires a well-planned, coordinated Extension and evaluation effort.
