Over the past 20 years, potato pest management in the Pacific Northwest (PNW) region of the United States has changed dramatically with the emergence and resurgence of new insect pests, including vectors of new, devastating plant pathogens. This chapter reviews the status of pest management in the PNW, along with future research aimed at enabling growers to maintain economically viable and sustainable potato production. The chapter describes the life cycles and effects of the main arthropod pests in the region, including the beet leafhopper, the potato tuberworm and the most significant emerging pest, the potato psyllid, vector of zebra chip disease.
