Dasineura jujubifolia was introduced into Korea for the first time in 2011, a gall midge feeding on jujube (Ziziphus jujuba Miller (Rhamnaceae)). Since then the jujube gall midge become a serious insect pest of Jujube in Korea. In this year, we surveyed regulated and alien insect pests by collecting damaged leaf samples from different regions in Korea. Jujube gall midge and its life stage were identified by morphological and genetic characteristics. For molecular identification, we analyzed the cytochrome c oxidase subunit I (COI) sequences of pest. In this study, we report the morphological description and genetic information of D. jujubifolia.

Xyrosaris Meyrick, 1907 is a small genus of the family Yponomeutidae, established by Meyrick (1907) for its type species Xyrosaris dyropa Meyrick, 1907. A total of nine species were recognized in the world. Most of species of the genus have been described by Meyrick at the early 20th century. Up to date, X. lichneuta Meyrick, 1918 has been reported from Korea.
In the present study, we review the genus Xyrosaris from Korea, with two new species: X. sp.1 and X. sp.2. Key to species, illustrations of adult, male and female genitalia, diagnosis and short description are provided.
Nysius Dallas, 1852, is one of the most common and widely distributed genera under the superfamily Lygaeoidae. Species under this genus are hard to identify due to similarity of the species and variability of the coloration. The Nysius species were collected with the help of aspirator and plastic vile in the perilla crop fields in RDA, Miryang, Korea. Korean species of the Nysius were identified, and three species including a newly reported species N. inconspicuus were recognized. Morphological and genetic characteristics of species were illustrated, and a key to species of Korean Nysius was provided. The DNA barcoding information of N. plebeius and N. inconspicuus were recorded.
The genus Pachynoa Lederer, 1863 reported 13 species in the world.

흑백알락나비 (Hestina persimilis (Westwood, 1850))는 한반도의 평안남도 이남의 내륙지역에 넓게 분포하고, 국외의 경우 일본, 중국, 히말라야 일대에 서식하는 것으로 알려져 있다. 본 종에 대한 생활사 연구는 김과 서(2011)에 의해 월동유충, 종령, 번데기 등에 대한 일부 보고가 있을 뿐 자세한 생활사에 대한 기록은 전무하다. 본 연구를 통해 한국산 흑백알락나비의 생태적 습성 및 미성숙단계 (알, 유충, 번데기)의 형태적 특징 등 자세한 생활사 정보를 보고하고자 한다.
Here, we provided a lucid key for twelve lepidopteran quarantine pests in South Korea. They were selected based on border quarantine inspection data from 1996 to 2016 in S. Korea. They are belonging to eight families: Carposinidae, Crambidae, Pyralidae, Gelechiidae, Oecophoridae, Tineidae, Tortricidae and Geometridae, and also categorized into the three groups: prohibited, regulated and nonquarantine pests. The key includes diagnostic characters from head, thorax, fore- and hind-wings for each species examined.

Bursaphelenchus sinensis was first found in Austria from the wood packaging material imported from China. In Korea, B. sinensis was detected from dead branches of Pinus densiflora located in Jinju, Gyeongnam province. Morphology of B. sinensis was characterized by unique male spicule with weak rostrum and squared condylus, and female with small vulval flap and conical shaped tail. Genomic DNA of B. sinensis was extracted and ITS region was fully amplified by PCR. ITS-PCR product was analyzed by RFLP and also directly sequenced. Polymorphism by RFLP-ITS was matched with that of B. sinensis and ITS sequence data was identical to B. sinensis information in GenBank. The Korean isolate of B. sinensis, Bs-Jinju, was submitted to GenBank and acquired the accession number, #MG934676. Host pathogenicity of B. sinensis was tested by artificial inoculation of nematode (30,000/ sapling) on 5-year-old P. densiflora. There were no disease symptoms in all tested pines inoculated by B. sinensis, whereas 100% mortality showed on pine saplings by B. xylophilus inoculation. This is the first report of B. sinensis in South Korea.

전라북도 완주군 구이면에서 채집한 사마귀목(Mantodea) 사마귀과(Mantidae) 넓적배사마귀속(Hierodula)의 한국 미기록종 Hierodula formosana Giglio-Tos, 1912, 붉은긴가슴넓적배사마귀(신칭)을 처음 보고한다. 이 종은 그동안 국내에 알려진 Hierodula patellifera (Serville, 1839), 넓적배사마귀와 동일하게 느티나무, 벚나무 등 활엽수의 우거진 수관부에 매달려 전 생애를 보내는 생태적 특징이 있다. 형태적으로 같은 속 넓적배사마귀와 비교하였을 때, 수컷생식기의 차이가 뚜렷하고 앞다리 기절부에 9~11개의 돌기가 있다. 또한 전흉이 뚜렷이 길고 앞가슴 아랫면이 붉은 빛을 띠는 등 구별이 가능한데, 현재 일본에서 확산되고 있는 외래종 Hierodula sp.와 동일종으로 여겨진다. 2017년 9월 전주에서 처음 암컷 3개체가 비공식적으로 채집된 이후, 2018년 9월 완주군 구이면 일대를 조사하였을 때, 총 암컷 4개체, 수컷 10개체를 채집할 수 있었다. 또한 유충의 탈피각, 전년도 알집 등이 함께 확인됨으로써 국내에 최근 정착한 외래종으로 의심되어 이를 보고하고자 한다.
