Additional information on DNA barcoding of the African armyworm, Spodoptera exempta (Walker) (Lepidoptera, Noctuidae) from Japan

摘要

After the occurrence of Spodoptera exempta (Walker) as a pest in Japan in 2010, we identified this pest again in the Nansei Is., Japan in 2012 and 2013. Using the method of standard DNA barcoding based on the additional specimens of S. exempta, we have identified three haplotypes from Japan. When compared the haplotypes of individuals from Africa, Australia, Papua New Guinea and Japan, the genetic structure of the Asia-Oceanian population was distinguished from that of the African population.
