본 조사지인 돌리네 습지보호지역은 경북 문경시 산북면 굴봉산 정상부에 위치하였으며, 물이 고이기 힘든 돌리네(doline) 지형에 형성된 희귀 습지이다. 뿐만 아니라 멸종위기종과 법적보호종이 분포하는 등 생물다양성 또한 매우 풍부한 것으로 평가되고 있다. 그러나 습지보호지역 주변으로 과수원 등 경작지가 형성되어 있어, 관리 및 보전을 위한 조사 및 대책이 필요하다. 따라서 본 조사에서는 습지보호지역의 체계적인 관리를 위하여 돌리네 습지의 곤충상을 조사하였다. 조사 방법에는 곤충의 다양한 습성과 서식환경을 고려하여, Searching, Sweeping, Pitfall trap, Bucket trap으로 총 4가지의 채집방법으로 조사를 실시하였다. 그 결과 총 11목 82과 188속 237종이 확인되었으며, 이중 딱정벌레목이 가장 많이 출현하였다. 특이사항으로 환경부지정종 51종(중복포함)이 조사되었으며, 그중 멸종위 기종 1종이 확인되었다. 본 연구를 통해 돌리네 습지보호지역의 곤충상을 파악하고 관리 및 보전에 대한 기초자료를 제공하고자 한다.

본 연구지점은 전라북도 완주군 운주면 고당리에 위치한 왕사봉(300m)의 신갈나무-굴참나무군락으로 주변에 계류가 흐르고 있으며, 소규모 산지와 저수지가 다수 위치해 있다. 또한 인근에 운주계곡 캠핑장이 위치해 있어 인위적 간섭이 잦은 지역이다. 그러므로 산림생태계에서 중요한 역할을 담당하고 있는 곤충 중 하나인 딱정벌레목에 대하여 군집분석을 실시하였다. 조사 방법으로는 직접찾기, 버킷트랩, 함정트랩 을 이용하였으며, 2015년 6월에서 10월까지 매달 1회 채집을 실시하였다. 그 결과 총 24과 70속 88종 417개체의 딱정벌레목을 확인할 수 있었으며, 이 중 붉은칠납작먼지벌레의 우점도가 높은 것으로 나타났다. 군집분석 결과 비교 대상들 간의 우점 정도를 나타내는 지표인 우점도 지수(DI)는 0.434, 군집의 복잡성을 나타내는 다양도 지수(H’)는 3.105으로 확인되었다. 또한 군집 내 종조성의 균일한 정도를 나타내는 종균등도 지수(EI)가 0.693이며 단위 지역에 존재하는 종의 수를 뜻하는 종풍부도 지수(RI)가 14.42로 확인되었다.

The Celyphidae, commonly known as beetle flies or beetle-backed flies, are a family of Diptera. The scutellum is enlarged and forming a protective shell over the abdomen, giving them a beetle-like appearance. Species in the family are mostly found in tropical region, especially in South East Asia. Records of North East Asia are rare, in China, some species are found in Southern region. In Japan, few species found in Okinawa region, but only one record of Celyphidae near in mainland area. In this research we firstly record specimen of genus Spaniocelyphus sp., from Korea stored in National Science Museum Korea and Kyongpook National University with comparison of specimen from Tsushima island, Nagasaki prefecture stored in Osaka Natural History Museum.

In the past, only one species known for Subtribe Physoderina from Korea. In this study reporting 2 genera and 2 species, Lachnoderma asperum Bates, 1883 and Physodera unicolor Ma, Shi & Liang, 2017, as new record to Korea. Taxonomic key, adult habitus, genitalia and distributional information are provided.

Gonggeom-ji is designated wetland protected area by the Ministry of Environment of Korea in 2011 because of it’s high biodiversity and historic value. It contains a reservoir, paddy and forest site which has diverse niches for insects. Three transect lines of 50m were designated. Data were collected in May, October, November in 2017 represented as seasons for spring, summer and autumn respectively. Quantitative methods were conducted along each transect line by sweeping and pitfall trap. Based on this study total of 1079 individuals of insect fauna were collected, representing 170 species in 60 families and 8 orders. The highest diversity, richness and evenness index were observed in the forest site in May(4.77, 8.6 and 0.91 respectively) and the highest dominance index was observed in the forest site in November(0.64). The highest similarity index was observed in the reservoir site in May and August(0.519).

The mandible character of the Lucanidae is vary by considering of developmental difference in male individual specimen. Especially, species of Genus Cyclommatus Parry, 1862 presents strong mandibular allometry. In this research, The species group which related to Cyclommatus montanellus Möllenkamp, 1904 has been evaluated for the first time in this research with inner teeth composition and positioning to establish clear taxonomic key to each species.

Until now, 12 subspeceis of Eucarabus (Parhomopterus) sternbergi has been recorded in South Korea and some were described by foreign entomologist without comparative examination. In addition, most of them were not reviewed since the original description. Therefore, based on this study, all subspecies of this group in South Korea were revised taxonomically, and a new subspecific key was provided. As a result, 8 subspecies of Eucarabus (Parhomopterus) sternbergi were confirmed in South Korea and their new synonyms are as follows: Eucarabus (Parhomopterus) sternbergi sternbergi (Roeschke, 1898) = E. (P.) s. gimhwa (Rapuzzi, 2015); E. (P.) s. honamensis (Kwon et Lee, 1984) = E. (P.) s. jindoensis (Rapuzzi, 2015) = E. (P.) s. goheungicus (Rapuzzi, 2015); E. (P.) s. schnelli (Lassalle, 1999) = E. (P.) s. deogyusan (Rapuzzi, 2015).

Carabidae is one of the largest family in Coleoptera, approximately as a 90% of Adephaga. Up to now, 40,000 species of 33 subfamilies are known worldwide. Therefore, they have been adapting to a variety of environments. This family belong to the superfamily Caraboidea of suborder Adephaga. Among them, family Trachypachidae is very similar to family Carabidae and family Rysodidae sometimes has been treated as a subfamily of this. In addition, from the past to the present, the classification of family Carabidae has been complicated in the states of higher taxa by authors etc. Recently, the taxonomic studies upgraded according the advanced natural science, genetic or phylogenetic methods and development of new methods etc. Nevertheless, their classification is still mainly based on the external morphology and the genital characters. Multiple application of these classification methods, including genetic analysis, endophallus inflation and microscopic observation etc., are being help to solve the taxonomic problems of family Carabidae.

Background: The plant Aster koraiensis has long been used as an ingredient in folk medicine. It has been reported that Aster koraiensis extract (AKE) prevents the progression of diabetes-induced retinopathy and nephropathy. However, although these beneficial effects of AKE on diabetes complications have been identified, the antidiabetic effects of AKE have not yet been completely investigated and quantified. In the present study, the glucose-lowering and antioxidant effects of aqueous and ethanolic AKEs were evaluated. Methods and Results: The glucose-lowering effects of aqueous and ethanolic (30%−, 50%−, and 80%-ethanol) AKEs were investigated via α-glucosidase inhibitory assays. The mode of inhibition by AKEs on α-glucosidase was identified through kinetic analysis. The total antioxidant capacity of each of the 4 AKEs was evaluated by assessing their conversion rate of Cu2+ to Cu+. The content of chlorogenic acid and 3,5-di-O-caffeoylquinic acid, the bioactive compounds in AKE, in each extract were analyzed by high performance liquid chromatography (HPLC). The AKEs showed potent α-glucosidase inhibitory activity with mixed inhibition mode, and significant antioxidant capacity. Conclusions: These results of this study suggested that the AKEs tested had α-glucosidase inhibitory and antioxidant effects. Among the extracts, the 80% ethanol extract showed the most significant α-glucosidase inhibitory activity, with a half maximal inhibitory concentration (IC50 value) of 1.65 ± 0.36㎎/㎖ and a half maximal effective concentration (EC50 value) for its antioxidant activity of 0.42 ± 0.10㎎/㎖. It can therefore be used as a source of therapeutic agents to treat diabetes patients.

Background : Dry eyes are caused by highly increased osmolarity of tear film, inflammation, and apoptosis of the ocular surface. Polygonum cuspidatum is a herbaceous perennial plant of the genus Polygonum found in Asia and North America. However, the effects of P. cuspidatum aqueous extract (PCE) on hyperosmolarity-induced inflammation and apoptosis in human corneal epithelial cells have not been examined. Methods and Results : Hyperosmotic media induced human corneal epithelial cell (HCEC) cytotoxicity though increased inflammation, apoptosis, and oxidative stress. PCE treatment significantly inhibited expression of cyclooxygenase-2 and inflammatory cytokines (interleukin-6 and tumor necrosis factor-α), and activation of NF-κB p65 in hyperosmolar stress-induced HCECs. In addition, Hyperosmolarity-induced increase in BAX expression and activation of cleaved poly (ADP-ribose) polymerase and caspase 3 were attenuated in a concentration-dependent manner by PCE. PCE treatment restored anti-oxidative proteins such as Heme oxygenase-1 (HO-1), Superoxide dismutase-1 (SOD-1), and Glutathione peroxidase (GPx) in hyperosmolar stress-induced HCECs. Conclusion : PCE protected against hyperosmolar stress-induced inflammation, apoptosis, and oxidation by inhibiting expression of COX-2, BAX, MMP9; activation of NF-κB, caspase 3, and PARP; and increasing expression of MUC4 and anti-oxidative proteins. Overall, our data provide insight into the protective effects of PCE as a candidate for eye health.
