The migratory locust, Locusta migratoria, is one of the famous insect pests in the world. This species reveals several morphological variations; however, 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 with red-brown color were suddenly occurred in the southern region (Haenam-gun, Jeollanam-do) in Korea. Generally, L. migratoria collected in Korea has revealed green color, indicating that the occurrence of the red-brown L. migratoria is unprecedented. In this study, mitochondrial COI sequences of 6 red-brown and 6 green individuals of L. migratoria were analyzed to examine 1) linage of the Korean L. migratoria and 2) co-relation between color and genetic difference. The analysis results reveal that all 12 individuals are belonging to the Northern linage; however, they have genetic divergences from 0% to 0.9%, consisting of five haplotypes. In addition, the red-brown and green individuals did not show genetic differences. Our study suggests that the Korean L. migratoria has genetic divergence which do not related with color differences. Additional studies should be need to examine the origin of the Korean L. migratoria and their geographical relationships.
