Abstract

Bemisia tabaci (Hemiptera: Aleyrodidae) is one of the major insect pests causing economic damages to over 900 different crops in the world. Especially, B. tabaci JpL (L. japonica) is known as a species living only in Japan and Korea so far, and mainly in Lonicera japonica and specific plant species. This study was conducted to investigate the occurrence and spread of B. tabaci JpL on Jeju Island in 2019. Of the total 25 areas surveyed, 1,003 individuals of B. tabaci JpL adults were collected from 24 L. japonica and one Conyza sumatrensis. All populations identified belonged to the JpL species. The result of this study showed that the population of B. tabaci JpL has increased at very high speeds to date compared to the previous reports in Korea.

노린재목(Hemiptera) 가루이과(Aleyrodidae)에 속하는 담배가루이(Bemisia tabaci Gennadius)는 전 세계적으로 900종 이상의 다양한 작물에 경제적 피해를 주고 있는 주요 해충이다. 특히 이 중 담배가루이 JpL (Lonicera japonica)은 현재까지 일본과 한국에서만 서식하는 종으로 보고되어 있으며, 주로 인동덩굴(Lonicera japonica) 및 일부 식물 종에만 서식하는 것으로 알려져 있다. 본 연구는 2019년 제주도 지역 담배가루이 JpL의 발생 현황 및 확산 정도를 확인하기 위하여 수행되었으며, 총 25개 채집지역 중 24개 지역의 인동덩굴 및 1개 지역의 큰망초(Conyza sumatrensis)에서 담배가루이 JpL 성충 1,003개체를 채집하였다. 채집된 담배가루이 성충의 유전자 염기서열을 분석한 결과, 분석된 모든 담배가 루이는 JpL로 확인되었으며, 본 연구의 결과 담배가루이 JpL의 개체수는 이전에 국내에서 보고된 이후 현재까지 매우 빠른 속도로 증가하고 있음을 확인하였다.
