Abstract

An outbreak of the migratory locust, Locusta migratoria, in the environment-friendly reclaimed plantations of forage crops in Sanyimyeon, Haenam-gun, Jellanam-do, Korea in August 2014 caused severe damages to various crops. Owing to its first occurrence in the Korean history, the causes underlying the outbreak and phase-transition of the migratory locust were not known. It is critical to establish the genetic relationship of the migratory locust in Sanyimyeon, Haenam-gun with the other previously reported strains in the world in order to understand the mechanisms responsible for its outbreak. The gene sequences of the 16S ribosomal RNA (rRNA) and displacement-loop (D-loop) of the mitochondria of various regional species of the migratory locust were used to perform the phylogenetic analysis. Our results suggested that the migratory locusts in Sanyimyeon, Haenam-gun are closely related with the Eurasian strains of the northern lineage. In future, these two mitochondrial genes can be used for elucidating the genetic population structures in migratory locusts in various regions. In addition, the sequence information of these genes can be used to enhance our understanding of the genetic basis of the outbreak of migratory locusts.

전라남도 해남군 산이면에 있는 간척지 중 친환경 사료작물 재배지에서 2014년도 8월에 풀무치(Locusta migratoria)가 대발생을 하여, 식량작물과 사료작물에 커다란 피해를 주었다. 오랜 기간 작물에 피해를 주지 않던 migratory locust가 어떠한 원인들에 의하여 대발생하여 해충화 되었는지에 아직까지 모르는 실정이다. 대발생의 원인을 규명하기 위한 연구의 일환으로 해남군 산이면에서 발생한 풀무치의 마이토콘드리아에 존재하는 16S ribosomal RNA와 D-loop의 염기서열을 분석하여 이들과 다른 지역계통간의 유전적인 연관성을 분석하였다. 그 결과 해남군 산이면에서 대량 발생한 풀무치는 북방계통 중 유라시아 대륙지역형과 유전적으로 가장 가까운 것으로 나타났다. 앞으로 2개의 표적 유전자는 국내외 유전적 집단 구조 비교에 활용할 수 있으며 대발생 풀무치의 대발생 원인을 분석하는데 기여할 수 있을 것이다.
