Ah Ram Son,Deuk-Soo Choi 한국응용곤충학회 2019 한국응용곤충학회 학술대회논문집 Vol.2019 No.04
해외 수입농산물의 양이 점차적으로 증가하여 다양한 병해충의 유입 가능성이 증가함에 따라, 이들을 신속하고 정확하게 판별하기 위하여 DNA 염기서열을 이용하여 형태학적 동정을 보완하고 있다. 현재 바구미과의 Sternochetus속 에 속하는 관리해충은 S. mangiferae와 S. frigidus, 그리고 S. olivieri가 있으며, 태국에서 수입된 망고에서 2018년 9월부터 2019년 1월까지 7차례에 걸쳐 바구미류가 검출되었고, 형태학적 형질 및 DNA 바코드를 이용하여 S. olivieri로 동정하였다. 추가로, Sternochetus속에 속하는 종들의 분류학적 형질을 이용하여 동정의 수단을 제공하였다. 본 연구결 과는 수입 및 반입되는 망고에서 검출되는 바구미류의 신속하고 정확한 진단에 활용될 수 있을 것으로 판단된다.

Ah Ram Son,Deuk-Soo Choi,Kyung-ill Lee,Soo Jung Suh 한국응용곤충학회 2018 한국응용곤충학회 학술대회논문집 Vol.2018 No.10
In 2017, a total of 82 non-target species representing six orders of insects were captured in four types of tephritid fruit fly (Diptera: Tephritidae) surveillance traps located in Korea; the species included 6 families of Coleoptera, 1 of Dictyoptera, 17 of Diptera, 2 of Hemiptera, 3 of Hymenoptera, 1 of Neuroptera, 4 of Lepidoptera, and 1 of Raphidioptera. Of these, Diptera were the most abundant; the main families included Muscidae, Tephritidae, and Anthomyiidae. Herein, based on a survey, we present a list of the species of non-target insects captured in the tephritid fruit fly surveillance traps.

A total of 53 nontarget species representing six orders of insects were captured in the codling moth surveillance traps placed in Korea over the last eight years. These included 20 species (37.7%) of moths (Lepidoptera) belonging to 9 families of which 9 species were tortricids, 12 species (22.6%) of beetles (Coleoptera) belonging to 10 families, 11 species (20.8%) of flies (Diptera) belonging to 7 families; 4 families of true bugs (Hemiptera) including one species of Anthocoridae (9.4%); 1 family of Hymenoptera including 2 species of Formicidae (3.8%) and 1 family of Neuroptera including 3 species of Chrysopidae (5.7%). A list of the species of nontarget insects captured in the codling moth surveillance traps is provided. A brief diagnosis and photographs of Aterpia issikii Kawabe, the tortricid moth newly documented in Korea are provided.
Insects collected from pheromone traps for monitoring on exotic pests over the last seven years
Ah Ram Son,Soo Jung Suh,Jae Myeong Heo,Kyung-bong Koh 한국응용곤충학회 2017 한국응용곤충학회 학술대회논문집 Vol.2017 No.10
Korea has been importing large quantities of plant materials from countries annually all over the world. Accordingly,various kinds of pests have been also detected during import inspections. In addition, these days the weather in Koreahas been getting warmer and a number of imported subtropical and tropical crops are being cultivated in greenhouses.In these regards, conducting a monitoring survey by using pheromone traps is required in order to prevent introductionand settlement of invasive species to Korea. we provide a list of insects collected from five types of pheromone trapscollected while monitoring exotic pests over the last seven years. Data from the monitoring surveys of pheromone trapsfrom 2010 to 2016 was extracted from database of the Plant Quarantine Integration System (PQIS) developed by theAnimal and Plant Quarantine Agency (APQA). As a result of our review on the PQIS database, 119 species were identified.The families forming the main groups are Tephritidae, Tortricidae, Camillidae and Cosmopterigidae. We believe that researchersand inspectors in charge of quarantine need to be well aware of the species collected from monitoring traps.

혈관 수축력 및 혈압 조절에 관여하는 것으로 알려진 아라키돈산을 물질 대사시키는 CYP2C19 유전자는 최근 심혈관 질환 관련 연구의 새로운 유전자로 제시되고 있다. 본 연구에서는 CYP2C19 유전자의 2 종류 다형성(CYP2C19<SUP>*</SUP>2와 CYP2C19<SUP>*</SUP>3)과 고혈압 간의 연관성을 조사하고자 하였다. 연세대학교 의료원 심장혈관병원에서 수집한 1,241명(환자군: 537명, 대조군: 704명)을 대상으로 SNaPShot™ assay를 이용하여 유전자형을 결정하였다. 두 종류의 다형성 가운데 CYP2C19<SUP>*</SUP>3의 대립인자형 및 유전자형의 빈도 분포가 환자군과 대조군 간에 유의한 차이를 나타냈다(p=0.019, p=0.023). 다중 로지스틱 회귀분석 결과, dominant model에서, CYP2C19<SUP>*</SUP>3 A 대립인자형은 본태성 고혈압과 매우 유의한 연관성을 나타냈다(OR, 0.723, p=0.032). 또한 CYP2C19 G-A haplotype은 고혈압 발생 위험을 매우 유의하게 감소시키는 것으로 조사되었다(OR, 0.714, p=0.015). 따라서 본 연구 결과는 CYP2C19<SUP>*</SUP>3 다형성이 본태성 고혈압 발생에 대한 보호 효과작용에 관여할 것이라는 증거를 제시하고자 한다. In humans, CYP2C19, a member of the cytochrome P450 subfamily, metabolizes arachidonic acid to produce epoxyicosanoid acids, which are involved in vascular tone and regulation of blood pressure (BP). Recent findings suggest that CYP2C19 gene polymorphisms might be considered as a novel candidate gene for cardiovascular disease. We thus focused on the Korean population to explore the association of two polymorphisms (CYP2C19<SUP>*</SUP>2 and <SUP>*</SUP>3) in this gene and essential hypertension (EH). A total of 1,241 participants (537 hypertensive subjects and 704 healthy controls) were recruited from the Yonsei Cardiovascular Genome Center in Korea. The CYP2C19 polymorphisms were genotyped using the SNaPShot™ assay. The allele and genotype frequencies of CYP2C19<SUP>*</SUP>3 showed significant difference between hypertensives and normotensives (P=0.019 and P=0.023, respectively). Logistic regression analysis indicated that the CYP2C19<SUP>*</SUP>3 A allele carriers were significantly associated with EH (OR, 0.723; 95% CI, 0.538-0.972, P=0.032) under a dominant model. In addition, CYP2C19 G-A haplotype (2C19<SUP>*</SUP>2 G-<SUP>*</SUP>3 A combination) was found to significantly reduce EH risk (OR, 0.714, P=0.015). We believe this provides evidence that CYP2C19<SUP>*</SUP>3 polymorphism may contribute to a protective effect in the development of EH.
