Abstract
We conducted quarantine insect species diversity monitoring using DNA barcoding with 517 lepidopteran samples that were obtained from quarantine inspections of foreign vessels entering Korea. For species delimitation and species identification of the analyzed samples, we applied a 2% cutoff rule. Consequently, 145 (368 samples) were considered taxonomically identified. Therefore the number of samples that were identified to the species level was relatively low, at approximately 71%. Thirty of 145 species were not known in Korea, three, i.e., Noctua pronuba (Noctuidae), Orthosia hibisci (Noctuidae), and Pieris brassicae (Pieridae), were checked as ‘Regulated pests’ in Korea.
