The migratory locust, Locusta migratoria, is one of the famous insect pests in the world. Although the species reveals several morphological variations, it is largely divided into two lineages, Southern (Africa, Southern Europe, Southern Asia, and Australian) and Northern (East Asia, Eurasian continent). In 2014, a large number of L. migratoria nymphs with red-brown color were suddenly occurred in the southern region (Haenam-gun, Jeollanam-do), Korea. In this study, mitochondrial COI sequences were analyzed to recognize the genetic identity of L. migratoria with nymph or adult samples collected from 9 localities in Korea. The analysis results reveal that all individuals are belonging to the Northern lineage.
