The genus Trichophysetis is one of the taxa that has recently undergone frequent changes in its taxonomic position. Only four species have been recorded in Korea, including synonymized Hendecasis species. Recent studies on the taxonomic classification of Trichophysetis have not addressed any species inhabiting Korea. Therefore, it is necessary to conduct a renewed morphological analysis of Korean species. In this study, we compare and analyze four Korean Trichophysetis species with one newly recorded species.

Mocis frugalis (Fabricius, 1775), the sugarcane looper, was collected in Byeonsanbando National Park in South Korea for the first time. This species is known as a major crop pest, especially to sugarcane at tropical and subtropical regions. Due to climate change and the subtropicalization of the southern part of the Korean Peninsula, some tropical and subtropical crops are cultivated in Korea, including sugarcane. Besides, Oryza sativa L. and Zea mays L., which of main crops in Korea, are known as host plants of M. frugalis in the Oriental region. Even if unclear of domestic settlement, precision monitoring will be necessary.

Global warming and changes in ecosystems are either causing a rapid decline in insect diversity on earth or, on the other hand, are increasing the likelihood of unexpected insect pests emerging. This study summarizes and reports the followings: Introduction to the Insects of Red Data Book of Korea and Nationally Protected species, the establishment of monitoring strategy for exotic insects by the investigation of species distribution range through field surveys and others, the dispersal of exotic insects, and with the expansion of exotic insects and development of ecosystem impact prediction model.

Two new species, Stericta jaeshini Kim & Bae, sp. nov. and S. atroaurantiaca Kim & Bae, sp. nov. are described from Laos and Cambodia. About 50 species of the genus Stericta have been recorded from Southeast Asia, but it has not been recorded to occur in Laos and Cambodia previously. We record the presence of this genus in these two countries for the first time in this study. Illustrations of adults and genitalia of examined species are provided.

금번 연구를 통해 외래산림해충 확산 분석 플랫폼 K-SDM (K-SDM)의 해충 분포 기능이 개발되었다. 해충 분포를 보여주는 기능은 2가지로 구현되며, 조사 자료를 바탕으로 현재 국내의 해충 분포를 나타내는 “외래산림 해충분포”기능과 데이터를 분석하여 예측되는 미래의 해충 분포를 제공하는 “외래산림해충예측”기능이 있다. “외래산림해충분포”는 조사자에 의해 현장에서 구축된 DB 현황을 지도상에 수치로 나타내며, 입력 기간, 해충 종 별로 구분이 가능하여 원하는 해충종의 분포를 선택하여 볼 수 있다. 지도 좌측에는 각 도별로 조사된 해충 개체수의 통계를 도표로 제공하여 수치상으로도 해충 분포를 파악할 수 있다. “외래산림해충예측”은 DB를 분석 하고 미래 기후 시나리오를 적용하여 도출한 미래의 해충 예측 분포도를 사용자에게 제공되며, 미리보기 이미지 와 함께 원본자료가 첨부되어 좀 더 자세한 정보를 열람할 수 있다. 본 플랫폼의 해충 분포 기능은 최근 기후변화 등으로 외래산림해충의 발생이 증가하는 추세에 맞춰 이들의 현재 분포와 미래의 분포양상을 조기 파악하여 이를 통한 추후 조기 방제 및 대응책 마련 등에 크게 기여할 것으로 기대된다.

Recently, as the possibility of unexpected outbreaks of alien insects has increased due to climate change such as global warming, the importance of early control through rapid and accurate spread of exotic forest pest and change prediction diagnosis is required. This study summarizes and reports the followings: the establishment of monitoring strategy for exotic insects by the investigation of species distribution range through field surveys and others, the development of new diagnostic technique through microstructures and life-cycle, the dispersal of exotic insects, and ecological impact assessment using ecological methods and with the expansion of exotic insects and development of ecosystem impact prediction model.
