Yeyeun Kim,Hyojoong Kim,Seunghwan Lee 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.05
The members of the genus Chaitophous(Hemiptera: Aphididae) has limited host specificity on two genera of the family Salicaceae, Salix and Populus. In this study, as a result, we discovered 5 species new to Korea: C. Horii Takahashi 1939, C. leucomelas Koch 1854, C. salijaponicus Essig & Kuwana 1918, C. tremulae Koch 1854, and C. populialbae yomefuri Shinji 1941.

Grapevines are cultivated globally, and are also damaged by a large number of insect pests especially including leafhoppers. Leafhoppers are one of the important insect pests on various crops including grape. Among them, the genus Arboridia Zachvatkin (Hemiptera: Auchenorrhyncha: Cicadellidae: Typhlocybinae) was known as insect pests against grape farming. Eighty species were described in the genus in the world, and eight species were recorded in the Korean Peninsula so far, which are: Arboridia apicalis, A. kakogawana, A. koreacola, A. maculifrons, A. nigrigena, A. okamotonis, A. silvarum, A. suzukii. Among them, A. apicalis, A. kakogawana, A. maculifrons, A. nigrigena, A. suzukii have been known as important insect pests on grapes. In this talk, we propose a new species from the Korean Peninsula, and confirmed two new records: A. agrillacea and A. lunula. Additionally we present differential diagnoses of the Arboridia species damaging on grapevines for the field of applied biology.

Genus Tautoneura Anufriev, 1969 (Hemiptera: Auchenorrhyncha: Cicadellidae: Typlocybinae) were recorded 59 species in the world. Among them, only 1 species: Tautoneura mori has been recorded so far in the Korean Peninsula. Tautoneura mori is known as a major pest of Mulberry in China and Japan, and we also confirmed that it appears on Mulberry in Korea. In this talk, we confirmed two new records: Tautoneura japonica, Tautoneura tricolor to the Korean typhlocybinae fauna, and we also discovered one new species to science. Additionally, we provide biological information such as host plants and distributional records, with a key to the Korean Tautoneura species. We also discuss potential status of each species as an agricultural pest concerning its biological traits.

Lee, Seung-Hwan 한국동물분류학회 2001 Animal Systematics, Evolution and Diversity Vol.17 No.1
한국산 인도볼록진딧물속 (Indomegoura)을 정리하여 2종을 확인하였으며, 이 중 꼬마볼록진딧물 (I. nigrotibiae)을 한반도에서 처음으로 보고한다. 각 종에 대한 형태적 기술과 더불어 종 검색표를 작성하고, 기주식물 및 생활사에 대하여 논하였다. Two species of the genus Indomegoura Hille Ris Lambers (Hemiptera: Aphideidae) are recognized in Korea, including I. nigrotibiae (Tao, 1963) new to Korean Peninsula, Besides the descriptions, the host plants nad the key to the species of genus Indomegoura are provided and the biology of each of each species are discussed.
Taxonomic Study of the Genera Capitophorus and Hyperomyzus (Hemiptera: Aphididae) in Korea
Hwalran Choi,Seunghwan Lee 한국응용곤충학회 2010 한국응용곤충학회 학술대회논문집 Vol.2010 No.10
In the tribe Macrosiphini (Hemiptera: Aphididae), we discovered two new records in Korea, Capitophorus formosartemisae (Takahashi, 1921) and Hyperomyzus lactucae (Linnaeus, 1758) collected on Artemisia princeps and Sonchus oleraceus, respectively. They are illustrated and described, based on the macerated slide specimens of the apterous viviparous females.

The citrus flatid planthopper, Metcalfa pruinosa (Say, 1830) (Hemiptera: Flatidae), has a native distribution in eastern North America, It has recently invaded Italy in 1979 and has since spread to other European countries. In 2009, Metcalfa pruinosa was discovered in Seoul and the Gyeonggi Province, Republic of Korea. This is the first record in the eastern part of Palaearctic. One year after its discovery, in July 2010, we found significant populations and serious damage on many deciduous forest trees, ornamental trees, and agricultural crops in central regions of the Korean Peninsula. In this paper, we report the status of the outbreak and discuss the biology, morphological characters, distribution, host plants, and the importance of M. pruinosa as a potential insect pest in the Korean Peninsula.

The genus Arboridia Zachvatkin belongs to the tribe Erythroneurini of the subfamily Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae). A total of 69 valid species have been described in the Palaearctic and Oriental region. So far, seven species of this genus have been recorded in the Korean Peninsula. In this study, we present two new species, Arboridia sp. nov. 1, Arboridia sp. nov. 2, and provide a key to the Arboridia species in the Korean Peninsula with biological information such as host plants and distributions.
New record of an exotic Flatid species, Metcalfa pruinosa (Say) (Hemiptera: Flatidae) in Korea
Yeyeun Kim,Sora Kim,Seunghwan Lee 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.10
Metcalfa pruinosa (Say) (Hemiptera: Flatidae), the citrus flatid planthopper(CFP) is suddenly discovered this year in Seoul and Gyeonggi Province, Korea. CFP is originally distributed in the Eastern parts of North America(Metcalf and Bruner 1948), and recently spreading to European countries(Baker et al. 2008) such as northern Italy, Spain, and France. It is an economically important plant-sucking insect having wide host range including many agricultural crops such as grapefruit and citrus, and ornamental trees, camellias, azaleas, and magnolias(Dean and Bailey 1961) mediating plant viruses. We discovered large samples on Hosta longipes (Franch. & Sav.) Matsumura, Liriope platyphylla F.T.Wang & T.Tang, Weigela subsessilis L.H.Bailey, etc. in Seoul and Suwon on August 2009. In this report, we announce their taxonomic position, morphological characters, distribution, host information, and importance as a possible pest in the Korean peninsula.

The family, Machaerotidae (Stål), called tube-making spittlebugs, (Hemiptera: Auchenorrhyncha: Cicadomorpha) four tribes, 31 genera and 115 species in the world, and is mainly distributed in the Oriental and Palaearctic Regions. In Korea, two species, Makiptyelus dimorphus (Maki, 1914) and Taihorina geisha (Schumacher, 1915) have been recorded. This group have unique morphological characters as follows: Scutellum stretched, spine-like, flat or with sharp carinae and projections, longer than pronotum and forewing distinctly membranous or transparent. Additionally, nymphs make a calcareous tube using some woody dicotyledons and immerses itself in a rather clear fluid excretion inside the tube. In this presentation, the family Machaerotiade is reviewed in Korea. Morphological data, shape of calcareous tube, biological notes, and the key to Korean Machaerotidae species are presented.
Survey of DNA barcoding of Hemiptera
Doo-Sang Park,Paul D.H. Hebert 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.10
Recently, hundreds thousands of CO1 barcodes have been produced in many insect groups however, relatively little is known in Hemiptera. In this study, we newly determine 1173 sequences for 374 species distributed among 190 genera and 33 families collected mostly from North America. Average age of the specimen was 12.2 years and about 70% of the specimens produce barcode over 500 bp among examined 1700 specimens. Con-generic divergency calculated by K2P distance was 9.99 which was 11fold higher than the mean intraspecific variation. A steady increase of genetic variation through increasing taxonomic levels was also observed. We found several taxon groups with deep divergency (over 2.0 K2P distance) which were morphologically identified as a same species. Some mixed clusters with several species were also found and suggested more detailed study for these clusters through both morphological and molecular biological method.
