Fall armyworm Spodoptera frugiperda (Lepidoptera: Noctuidae) is a polyphagous agricultural pest that damages about 80 species of plants. It mainly damages Poaceae and plants used as food resources for humans. Its original habitat is the American continent, but it unintentionally settled in tropical and subtropical Asia, including Africa, India, and Sri Lanka. It occurs every year even in southern China, which is geographically adjacent to the Korean Peninsula, causing damage to crops. In Korea, it was first discovered on Jeju Island in June 2019 and is being discovered every year in Jeju and some inland areas. In 2023, there were a total of 13 discoveries, including those in the Jeju and Jeonbuk regions. Quarantine agency identified the maternal genotypes of all currently discovered individuals using COI and identified differences in genetic traits between individuals using the sex-related Z-chromosome. For comparison with the information on the individuals that invaded the country, 15 individuals from Guangxi and Guangdong provinces in China were collected and secured. Through the analysis of overseas samples, a database has been added to compare genetic information with domestic invasive species, and the reliability of the analysis is expected to increase.

Solenopsis invicta, known as the red imported fire ant, is an insect native to South America. This species was unintentionally introduced into Australia, New Zealand, several Asian countries, Caribbean countries, and the United States. It shows a high survival rate and settlement potential in human-habitable and non-living areas such as tropical rainforests, disturbed areas, deserts, grasslands, and roads. In Korea, invasions of red fire ants have been reported every year since 2017, and two invasions were discovered in 2023. Quarantine agency analyzing the haplotype and colony social type of S. invicta for surveillance and control. Population genetic analysis using Microsatellite Alleleic data of 66 loci to trace the origin of the invasion. Through research cooperation with the United States Department of Agriculture (USDA), we have received samples and expanded our genetic information database. This study analyzed genetic differences between 15 invasive populations and 44 reference groups. As a result of microsatellite analysis, the domestic invasive population showed a genetic structure similar to those in Guangzhou, China, and Florida, USA.

농림축산검역본부에서는 수입식물 검역과정, 현지조사, 연구사업 등을 통해 다양한 병해충 표본들이 확보되고 있으며, 2016년도부터 병해충 표본자원의 DB구축사업을 실시하고 있다. 농림축산검역본부의 해충표본실에는 2018년도 9월까지 약 6,400점의 표본 등록 및 바코드화가 완료되었으며, 올해까지 총 7,000점의 표본이 등록될 것으로 예상된다. 그 중 노린재목(Hemiptera)이 5,500점으로 전체의 85%를 차지하고 딱정벌레목(Coleoptera)이 377점으로 6%, 파리목(Diptera)이 188점으로 3%를 차지한다. 국제적으로 생물자원의 중요성과 확보 경쟁이 치열한 상황에서 생물표본가치의 증가 및 자료 구축을 통해 앞으로의 첨단 동정기술 개발과 동정매뉴얼 제작 및 업데이트를 위한 필수적인 재료로써 활용될 것으로 기대된다.

각진장미흰깍지벌레, 참식나무흰깍지벌레와 후박나무굴깍지벌레로부터 채집된 Encarsia explorata (Silvestri) [후박굴깍지좀벌 (신칭)] 및 담배가루이로부터 채집된 Encarsia lutea (Masi) [가루이좀벌 (신칭)] 을 국내분포로 처음 보고한다. 또한 이들 종들의 검색표, 식별형질, 사진자료, 분포 및 기주 정보도 함께 제공하였다.

가루깍지벌레는 열대지역에서 일반적인 해충으로 관상식물과 과수류의 큰 문제를 일으키는 해충이다. 캄보디아와 라오스에는 현재 가루깍지벌레과 22종 및 12종이 각각 보고되어 있다. 최근 이들 지역에서 가루깍지벌레과 연구를 수행하여 13종이 채집되었으며, 그 중 캄보디아에서 3종인 Dysmicoccus neobrevipes (Beardsley, 1959), Phenacoccus solani (Ferris, 1918), Rastrococcus iceryoides (Green, 1908) 와 라오스에서 6종인 Dysmicoccus neobrevipes (Beardsley, 1959), Paracoccus invectus (Williams, 2004), Phenacoccus solenopsis (Tinsley, 1898), Planococcus litchi (Cox, 1989), Planococcus minor (Maskell, 1897), Pseudococcus jackbeardsleyi (Gimpel & Miller, 1996)가 이들 국가로부터 처음 보고된다.

사철나무 잎과 가지에 발생하는 사철깍지벌레로부터4종의 면충좀벌, 제줄깍지좀벌, 주걱깍지좀벌, 장미깍지좀벌 및 Pteroptrix machiaveli (Girault)가 채집되었고, 이중 Pteroptrix machiaveli (Girault) [사철깍지네마디좀벌(신칭)] 1종을 국내분포로 처음 보고한다. 또한 이들 종들의 식 별형질, 사진자료, 분포 및 기주 정보도 함께 제공하였다.

The family Pseudococcidae or mealybugs (Hemiptera) are common pests in tropical region of the world and also considered as important pests on ornamental plants and fruit trees. The mealybug faunas in Cambodia and Laos were known to nineteen species and eight species, respectively (ScaleNet, 2014; CABI, 2015; FAO-IPM, 2014). Recently, we have collected thirteen mealybug species in Cambodia and Laos. Among them, seven species of mealybug are found for the first time: Phenacoccus solani (Ferris, 1918) and Rastrococcus iceryoides (Green, 1908) in Cambodia; Dysmicoccus neobrevipes (Beardsley, 1959) and Phenacoccus solenopsis (Tinsley, 1898) in both counties; Paracoccus invectus (Williams, 2004), Planococcus minor (Maskell, 1897) and Pseudococcus jackbeardsleyi (Gimpel & Miller, 1996) in Laos.

 ,  , Aleurolobus marlatti (Quaintance), Massilieurodes formosensis (Takahashi), and Pealius rhododendri Takahashi were found for the first time in Korea. This study provides a brief summary and photographs of the major characters of these species and an updated identification key to the whitefly species known to occur in Korea.

 ,  , The Indian wax scale, Ceroplastes ceriferus (Fabricius) is redescribed so that it can be distinguished from Ceroplastes pseudoceriferus Green, which it most nearly resembles and has been confused with in Korea. A dichotomous key, photographs, and DNA barcode information are also presented for identifying three Ceroplastes species from Korea.

 ,  , Two pupillarial species, Cryptoparlatorea leucaspis Lindinger and Fiorinia japonica Kuwana, are recorded for the first time in Korea. Both species were found on coniferous trees, Cryptomeria japonica and Torreya nucifera. Also an identification key, brief diagnoses, and photographs of Korean pupillarial species are provided to assist in their identification.
