The obscure mealybug, Pseudococcus viburni Signoret (Hemiptera: Pseudococcidae) is a polyphagous cosmopolitan pest, damaging vineyards and fruit orchards. The species has long been quarantined in Korea and has never been recorded in the wild in Korea. In this study, to confirm the absence of P. viburni in Korea, we have searched for the species from the orchards. 533 sites of persimmon orchards, 144 sites of apple and other orchards, and 281 sites of nurseries and greenhouses were surveyed for the last three years (2015-2017). As a result, P. viburni occurs neither in the wild nor in nurseries in Korea.
