Occurrence of an exotic whitefly, Siphoninus phillyreae (Haliday) (Hemiptera: Aleyrodidae) in South Korea and its potential pathway analysis
Keywords:Ash whitefly, invasive, monitoring, spread
The ash whitefly, Siphoninus phillyreae (Haliday) (Hemiptera: Aleyrodidae), was first found in southern areas of South Korea during September 2019. During the survey of 2021, no additional specimens of the ash whitefly were found other than the previously reported regions. Attempts to trace a possible pathway for exotic ash whitefly suggested that this species probably followed pathways of illegal importation of infested plants from China or Japan and was unintentionally introduced into South Korea based on a survey-based study. This whitefly has not been intercepted at ports of entry to South Korea on imported plant material between 1999 and 2019 according to the PIS database (2021). Because of its wide host range and an ability to buildup massive populations, it will require continuous monitoring to prevent the spread to other areas of the country and to minimize potential losses of agriculturally and horticulturally important plants.
