Genetic lineage of the migratory locust, Locusta migratoria in Korea based on COI sequences of mtDNA
The migratory locust, Locusta migratoria, is one of the famous insect pests in the world. Although the species revealsseveral 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 withred-brown color were suddenly occurred in the southern region (Haenam-gun, Jeollanam-do) of Korea. In this study, mitochondrialCOI sequences were analyzed to recognize the genetic identity of L. migratoria with nymph or adult samples collectedfrom 15 localities in Korea. The analysis results reveal that most of all samples are belonging to the Nothern lineage,and the Southern lineage was discovered only in Iksan and Chunju of Korea.
