Apristus Chaudoir is one of the genera in the tribe Lebiini Bonelli (Coleoptera: Carabidae). This genus is morphologically similar to Anomotarus and Syntomus of Lebiini. However, Apristus can be distinguished from the other genera by having a combination of the following characteristics: basal pronotum with distinct posterior angles in dorsal view; tarsal claws smooth without denticulate or pectinate. A total of 61 species of Apristus are distributed worldwide and only one species, Apristus striatus Motschulsky has been known in the Korean peninsula. As results of taxonomic studies on Korean Apristus species, we discovered a newly recorded species, Apristus cuprascens Bates of Apristus. A key to the Korean Apristus species, photographs of diagnostic characteristics and illustrations of male genitalia are provided.

Recently, many habitat corridors have been constructed in Korea, but the effect of corridor types, i.e. overpasses and underpasses, on arthropods was poorly examined. Therefore, we compared the effect of habitat corridor types in terms of abundance, species richness, and composition of carabid beetles. As a result, 3,737 ground beetles belonging to 60 species were collected by pitfall trapping across the northwestern forest–habitat corridor–southeastern forest transects in 2015. Abundance and species richness of total carabid beetles in underpasses were significantly lower than overpasses. And species composition of underpasses corridors was significantly different compared to other habitats, such as overpasses and forests. Although more samples are needed to understand the effect of corridor types, the current underpasses may be unfriendly structures to movement of ground dwelling arthropods as well as carabid beetles.

Longhorn beetles (Coleoptera: Cucujiformia: Chrysomeloidea: Cerambycidae) are the most well known coleopteran family by their species-diversity, ecological importance and morphological attraction. Because of their popularity, the immature stages of longhorn beetle are relatively well-studied. However, hardly any study on immature stage of longhorn beetle has been done in Korea until now. Here we provide first intensive research on immature stage of Korean longhorn beetle. Especially, two basic methods used in immature stage research; classical larva-adult matching by rearing and molecular identification by using DNA barcoding will be presented. This study will provide a robust foundation for further study of immature stage identification, DNA barcoding and phylogeny of cerambycidae.

일반적으로 한라산과 같은 산지는 저지대에 비해 식생, 지형 등의 자연환경이 고도와 경사에 따라 급격하게 변화하 기 때문에 특정 환경에 적응한 동물들이 환경에 대한 다양 한 특징을 나타내고 있다(Lomolino, 2001). 일반적으로 곤 충은 환경조건에 따라 크게 영향을 받는 것으로 알려져 있 으며(Kim, 1988), 특히, 딱정벌레류의 대부분 곤충들은 서 식지 변화, 하층식생과 낙엽량, 숲의 나이와 토지 조건, 온도 와 습도 변화 등의 환경변화에 매우 민감하여 산림의 형태 에 따라 분포하는 종이 달라지기 때문에 고립된 상태 또는 제한된 공간 내에서 특정 종의 급격한 변화는 그 지역의 환경변화를 반영함으로 기후와 서식지 등의 변화를 분석할 수 있는 환경지표성 곤충으로 인식되고 있다(Thiele, 1977; Maclean et al., 1992; Niemela et al., 1993; Ishitani and Yano, 1994; Butterfield et al., 1995; Ings and Hartley, 1999; Magura et al., 2000; Niemela et al., 2000; Koivula and Niemelä 2002; Melnychuk et al., 2003; Rainio and Niemela, 2003; Argyropoulou et al., 2005; Ohsawa, 2005; Apigian et al., 2006; Avgin, 2006; Sandoval et al., 2007; Žiogas and Vaičikauskas, 2007; Timmetal., 2009; Riley and Browne, 2011). 국내에서도 이러한 환경변화에 대한 딱정벌레 이용 연구의 중요성을 인식하여 고도, 식생 등 환 경변화에 대한 종 다양도 및 풍부도 분석, 계절에 따른 개체 군 변동, 지역적인 발생과 변화 등에 관한 연구가 수행되고 있다(Park et al., 1997; Jung et al., 2005; Yeon et al., 2005; Yang et al., 2006; Jung et al., 2011; Lee, 2011; Oh et al., 2011). 본 연구는 한라산국립공원에 서식하는 딱정벌레의 월별· 계절별 분포 특성을 파악하기 위해 성판악(750m)에서부터 시작하여 정상인 백록담(1950m)과 어리목(970m)에 이르 는 동서길이 약 18km구간에서 23개 조사구에 Pit-fall trap 을 설치하고 2010년 5월부터 10월까지 월 4회씩 설치 및 수거를 하였다. 조사결과 분포가 확인된 딱정벌레류는 총 16과 71종(14,405개체)으로 딱정벌레과가 22종(30.99%)으 로 가장 많고, 검정풍뎅이과 10종(14.08%), 송장벌레과 9종 (12.68%), 잎벌레과와 소똥구리과 각 6종(8.45%), 방아벌 레과 3종(4.23%) 등의 순으로 나타났다. 조사시기별 종 다 양성은 6월에 43종으로 가장 많은 종이 출현하였고, 8월(32 종), 7월(30종), 10월(25종), 9월(23종), 5월(21종) 순으로 나타났다. 출현 개체수는 10월 4,575개체, 9월 4,065개체 순으로 많았고, 5월 561개체로 적었다. 군집분석 결과, 종다 양도(H')와 종균등도(EI)는 7월(H'=2.448, EI=0.720)이 가 장 높고, 종풍부도(EI)는 6월에 5.229로 가장 높게 나타났 다. 반면 종다양도와 종균등도는 10월(H'=0.695, EI=0.216), 풍부도는 9월(RI=2.647)에 가장 낮게 나타났다. 시기별 출 현종을 분석한 결과 윤납작먼지벌레의 연간 2세대가 발생 하는 종임을 재확인하였다. 또한 분류군에 따라 출현시기에 차이가 있는데 이는 한라산국립공원에 출현하는 딱정벌레 목 곤충들 사이에 공간적, 시간적 출현과 먹이자원의 이용 에 있어 서로 경쟁을 피하며 공존할 수 있는 여건이 형성되 어 있음을 알 수 있었다. 본 연구결과는 아열대 기후로 인해 이국적이고 다양한 식생들이 수직 분포를 잘 나타내고 있고, 많은 기생화산들 과 분화구 및 고산 습지와 고산초지대 등 다양한 환경으로 다른 공원에 비하여 동․식물들이 다양하고 풍부하며 자연환 경도 비교적 잘 보전되어 있는 한라산국립공원지역에서 딱 정벌레의 월별·계절별 분포특성을 조사하여 향후 환경변화 에 대비한 한라산국립공원의 안정된 자연생태계를 유지 관 리하는데 필요한 기초 자료로 제공하고자 한다.

지리산둘레길 주변의 딱정벌레류의 분포 및 다양성을 분석하였다. 2014년 5월부터 10월 초순 까지 조 사된 딱정벌레종수는 13과 38종이다. 가장 많이 채집된 종은 Harpalidae로 12종이며 다음으로 Carabidae가 10종으로 조사되었다. 개체수가 가장 많이 발견된 종은 Brachinidae로 1,059개체였다. 월 별 개체수는 5월이 332개체, 6월이 560개체, 7월이 501개체, 8월에는 955개체로 가장 많았으며, 9~10 월에는 736개체로 채집되었다. 고도별은 300m에서 474개체, 400m에서 975개체, 500m에서 657개체, 600m 이상에서는 978개체로 채집되었다. 사면별 분포는 남서사면에서 9과 26종 1530개체, 북동사면에 서는 11과 33종 1554개체가 채집되었다. 남서 사면 다양도 지수 2.224(0.966) 균재도 0.683 우점도 0.156이며 북동 사면 다양도 지수 2.079(0.903) 균재도 0.595 우점도 0.240이었다. 남서 사면에서 월 별 다양도 지수는 6월 2.141(0.930), 균재도 6월 0.791 우점도 는 8월 0.324로 가장 높다 북동 사면에 서 월별 다양도 지수는 5월 2.098(0.911), 균재도 5월 0.818 우점도 는 7월 0.451로 가장 높았다. 숲가 꾸기 지역에서 400m, 600m이상 지역의 대조구가 각각 368, 342개체로 많이 채집되었다.

This study was conducted to investigate the community structure and species distribution of ground beetle assemblages in Yeongwol-gun (19 sites) and Donggang river basin area (6 sites). Ground beetles were collected by pitfall traps from 19 study sites from 2013 to 2014. A total of 67 species were identified from 9,710 collected ground beetles. Species richness in mountainous forests of Yeongwol-gun (55.8±1.90) estimated by rarefaction curves was higher than those in Donggang river areas (28.0±0.06). Four dominant species, Synuchus nitidus (3,974 individuals) and Synuchus cycloderus (2,595 individuals), Synuchus sp.1 (830 individuals), and Eucarabus cartereti cartereti (434 individuals) were occupied 80.7% of total, but their relative abundance were different according to geographical locations. Species richness of total carabid beetles was positively related to elevation (linear regression, F1, 23 = 22.41, adj. r2=0.47, P < 0.001) and it showed a U-shaped curve with longitudinal gradient (curvilinear regression, F2, 22 = 10.82, adj. r2=0.50, P < 0.001). And species richness maps that are focused on south-western areas of Gangwon-do including Yeongwol-gun, Jeongseon-gun, and Pyeongchang-gun were generated using ArcGIS 10.1. In species composition, longitude and elevation were best predictors to determine the distribution of carabid beetles by MRT analysis (Error = 0.517, CV Error = 1.04). These results indicated that habitat management regimes for biodiversity conservation should be conducted in considering geography and topography, although further studies are still necessary on the distributional pattern of other insect taxa and the relationship between biodiversity and more environmental variables.

This study was conducted to investigate the distributional characteristics of ground beetles and to provide basis information for biodiversity management including the ground beetles in the Naejangsan National Park area. Pitfall traps were installed throughout 20 sites within Naejangsan National Park during 2008 to 2011 to collect ground beetles. A total of 2,409 collected ground beetles were identified with 35 species belonging to 19 genera of 8 subfamilies. Coptolabrus jankowskii jankowskii, Eucarabus sternbergi sternbergi, and Pterosticus audax were dominant at the core area, while Pheropsophus jessoensis, Synuchus nitidus, Synuchus cycloderus, and Chlaenius naeviger were dominant at the border of the National Park and adjacent to the road or grassland. These differences of dominant species also affected to the similarity of species composition between core and border area, and caused increasing dissimilarities between sites with cluster analysis. Although the result of the present study was a case study using ground beetles, it will be helpful to develop a management strategy of biodiversity conservation in Naejangsan National Park and its surroundings.

To identify the key effects of human disturbance on terrestrial ecosystems is a major issue in the contemporary conservation. We compared the community structure of ground beetles among different forest patch sizes according to the different forest types. In addition, we examined how different functional groups and species responded to patch size, and habitat and geographical variables. We sampled ground beetles in 9 continuous forests and 18 patches including 6 deciduous, 6 Korean pine, and 6 Japanese red pine. Ground beetles were collected using 5 pitfall traps in each site, and replaced every month during May to October in 2013. Individual-based rarefaction curves indicated that higher species richness was found in continuous forests than forest patches irrespective of the forest types. Positive relationships were found between forest patch size and species richness of each functional group associated with forest habitat. When all patch size, geographical, and habitat variables were considered simultaneously for multiple regressions, patch size, longitude, latitude, elevation, organic matter, and litter depth were generally selected as significant predictor variables of the abundance and species richness of forest specialists, brachypterous, dimorphic, and large-bodied species, although longitude was only selected as a best predictor for 27 study sites in MRT. In conclusion, decreasing patch size is a major factor to the loss of biodiversity for ground beetles. To reduce biodiversity loss caused by habitat fragmentation, therefore, protecting as large as old-growth forests and improving habitat quality are critical for the biodiversity conservation and enhancement.

The longhorn beetle (Coleoptera: Cucujiformia: Chrysomeloidea: Cerambycidae) is one of the major family of coleoptera which contains more than 30,000 species worldwide. Because of their species-diversity, morphological attraction and ecological status, the family has received a massive global attention. However, in Korea, no thorough study on this family has been conducted within last twenty eight years. Here we update the latest knowledge of Korean longhorn beetle fauna. First, we give an historical overview of the longhorn beetle studies in Korea and correct some common species misidentifications. Then we provide the information of updated cerambycidae fauna with 4 new species and 9 species newly reported to Korea. Lastly, we discuss the importance of studying immature stage of cerambycidae and provide brief morphological, ecological information of two recently described species.

This study to figure out the diversity patterns and community structures of ground beetle of the Gyebang Mountain newly is incorporated into Odaesan National Park, Korea. A total of 47 species belonging to 20 genera of 12 subfamilies were identified from 483 collected ground beetles. Species richness was high in Pterostichinae (18 species, 39%), Carabinae (8 species, 18%), Harpalinae (7 species, 15%), Lebiinae (3 species, 7%), Bembidiinae and Nebriinae (2 species, 5%) and others (1 species, 2%). Twenty-three species were brachypterous and 24 species were macropterous. The dominant species was Synuchus nitidus (19.05%) and a subdominant species was Eucarabus cartereti cartereti (14.49%). Dominance, species diversity, species richness, and species evenness index were 0.56, 3.00, 3.85 and 0.70, respectively. Also, Acoptolabrus mirabilissimus ssp. 1 is discovered in the Mt. Gyebang area for the first time.

The effects of thinning on community diversity of wood-boring beetles were examined in Japanese Larch (Larix kaempferi) forest in In-je, South Korea in 2013. Three study sites were selected and thinning in the plots was conducted in 2010, spring 2012, and autumn 2012, respectively. Wood-boring beetles were collected every week using the 12-unit Lindgren multi-funnel traps with pheromone lure (Ipsdienol +50/-50 40mg, Ipsenol +50/-50 40mg) from mid-April to early November. Total 5 families (Cerambycidae, Curculionidae, Dryophthoridae, Scolytidae, Platypodidae), 62 species, and 26,638 individuals were collected. Diversity indices were 2.08, 2.02 and 0.76, and evenness indices were 0.55, 0.49 and 0.19 in 2010, spring 2012 and autumn 2012 thinning area, respectively. Among wood-boring beetles, the number of species of bark and ambrosia beetles were accounted for 44.4, 41.9 and 46.3% in 2010, spring 2012 and autumn 2012 thinning area, respectively. The number of individuals of bark and ambrosia beetles were accounted for 86.9, 82.2 and 98.4% in 2010, spring 2012 and autumn 2012 thinning area, respectively. Our results showed that the density of wood-boring beetles was the highest in the most recent thinning area, suggesting that thinning timing can influenced on the abundance of bark and ambrosia beetles. Among them, Ips subelongatus, I. acuminatus, and I. sexdentatus are species that mainly attack Japanese Larch. Ips subelongatus emerged faster than others and was the most dominant species.

A long term monitoring was carried out to compare altitudinal effects on insect community structures on high mountains and evaluate responses the monitoring and changed of insect communities induced by the climate change. These mountains were choose for Mt. Jeombong for northern part, Mt. Ilwol for middle and Mt. Beakun for southern. Each mountain was divided into three altitudinal gradients. They were collected three times a season from spring to autumn, using pitfall traps for ground beetles and UV light trap for moths. The present study presents preliminary results of analysis for the first year monitoring. In total 41beetle species and 326 moths were collected from the monitoring sites in 2012. abundance of ground beetles and moths were the highest in Mt. Baekun followed by Mt. Ilwol and lowest in Mt. Jeombong. Analysis of variance (ANOVA) results showed statistically significant differences among sampling area, species evenness and Shannon’s diversity index with altitude in species abundance as a response variable. Also we found statistically significant differences to three species of ground beetle and six species of moths with altitude. Although we expected a distinct cluster with the difference of altitude at each study site. one of ordination analysis, nonmetric multidimensional scaling (NMS), showed distinct clusters with the ground beetles assemblage at some altitude and moths assemblage at sampling date.

This study to figure out the diversity patterns, community structures, and seasonality of ground beetle assemblages in ecosystem and landscape conservation areas around the Wangpi-cheon area, Korea. A total of 38 species belonging to 20 genera of 8 subfamilies were identified from 2,486 collected ground beetles. Species richness was high in Pterostichinae (16 species, 42.11%), Carabinae (8 species, 21.05%), Harpalinae (5 species, 13.16%), Callistinae (3 species, 7.89%), Nebriinae (3 species, 7.89%) and others (1 species, 2.63%). The dominant species were Synuchus cycloderus(41.2%) and Aulonocarabus seishinensis seishinensis (13.4%) and their seasonal activities according to the sites were different. According to non-metric multidimensional scaling (NMDS), ground beetles and ecological grades could be divided into two distinct groups: St. 1, St. 2, St. 3 group and St. 4 group. Some species such as Pterostichus orientalis, P. vicinus and P. bellator bellator were particularly abundant at St. 4. Also, Acoptolabrus mirabilissimus ssp. 1 is discovered in the Wangpi-cheon area for the first time.

The present study is aimed to evaluate forest health in a fragmented urban forest using insects which are rarely used for evaluation of forest health. It is supposed that forest would be health if insect community in an urban forest is similar to that in healthy forests. Ants (Formicidae) and ground beetles (Carabidae) surveyed by pitfall trap method in the Hongneung forest located in the urban area of Seoul were compared with those in the Gwangneung forest. The Gwangneung forest is supposed to be health due to its high biodiversity and well-conserved nature. Ants of the Hongneung forest was much more abundant compared with those of the Gwangneung forest. However, ground beetles showed the opposite patterns; much more abundant in the Gwangneung forest than in the Hongneung forest. Species richness was higher in the Gwangneung forest than in the Hongneung forest, but species diversity was higher in the Hongneung forest. This dominance decreased species diversity in the Gwangneung forest. Thus, characteristics of insect community in the Hongneung forest were greatly different with that in the Gwangneung forest. This great difference of insect communities between the target and reference sites may indicate whether the Hongneung forest would not be health according to the working hypothesis, or may indicate simply the characteristic of the fragmented urban forest. In order to determine the significant decision, the repetitive studies are needed on this regard.

We investigated the spatial distribution of ground beetle species from the edge of secondary forests in Hwaseong-si, Gyeonggi-do. Nine secondary forests were selected, and 81 pitfall traps for collecting ground beetles were placed along forest interior―forest edge―forest exterior gradients during 14 June to 9 November, 2011. A total of 32 species belonging to 13 genera of 8 subfamilies were identified from 3710 collected ground beetles. Ten dominant species were selected for analysis. Five species such as Chlaenius micans (ANOVA, with Tukey's test, F2, 78=3.11, P=0.0502), Chlaenius ocreatus (F2, 78=2.76, P=0.0692), Dolichus halensis halensis (F2, 78=9.80, P=0.0002), Harpalus eous (F2, 78=2.73, P=0.0712), and Harpalus tridens (F2, 78=6.74, P=0.0020) were abundant at forest exterior. Three species such as Synuchus cycloderus (F2, 78=7.91, P=0.0007), Synuchus nitidus (F2, 78=9.72, P=0.0002), and Synuchus sp.1 (F2, 78=4.50, P=0.0142) were abundant at forest edge and forest interior. Coptolabrus smaragdinus branickii (F2, 78=3.24, P=0.0444) was abundant at forest edge and exterior. Finally, Chlaenius naeviger (F2, 78=1.39, P=0.2542) showed a wide distribution in this study. This study showed a significant edge effect on dominant ground beetles. Many environmental variables and prey items may be important factors for the spatial pattern of ground beetles. Because forest edges are generally important for many predaceous arthropods including ground beetles, the conservation and management of forest edges are important for maintaining biodiversity and ecosystem functions.

The wood-boring and bark beetle (Cerambycidae, Curculionidae, Scolytinae) community in Korean white pine, Pinus koraiensis Sieb. & Zucc., forests was surveyed using Malaise traps in 2007. A total of 1,669 wood-boring and bark beetles were collected, including 193 cerambycids from 16 species, 221 curculionids from 21 species, and 1,255 scolydid beetles from 6 species, of which the dominant species was the ambrosia beetle Xyleborus mutilatus Blandford. Ranked by order of population size, the wood-boring and bark beetle community in Korean white pine showed high dominance by one species of Scolytinae, suggesting the community was unstable and had low biological diversity. Thinning in Korean white pine forests influenced the abundance of bark and ambrosia beetles, whose populations in particular stands increased 1 year after thinning, and then decreased the following year.

Myanmar, which has a total area of 678,500 square kilometers (262,000 sq mi), is the largest country in mainland Southeast Asia, and the 40th-largest in the world. It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. Much of the country lies between the Tropic of Cancer and the Equator. It lies in the monsoon region of Asia, with its coastal regions receiving over 5,000 mm (196.6 in) of rain annually. Annual rainfall in the delta region is approximately 2,500 mm (98.4 in), while average annual rainfall in the Dry Zone, which is located in central Myanmar, is less than 1,000 mm (39.4 in). The average annual temperature is about 27℃(about 80℉). This expedition was conducted two times in two years (8.7~8.17, 2011; 2.2~2.9, 2012). As protected forest from government, these areas were almost natural conservation field. Pitfall trap, sweeping method, light trap and searching etc. were used to collect insect. As the result, totally about 30 families in Coleoptera was collected, among them Oodes species of Carabidae was highest number and species in Chrysomelidae, Cicindelodae, Scarabaeidae and Dynastidae etc., were collected. It was difficult to identification because of lack of references of this areas. Maybe lots of new or new recorded species will discover from Myanmar. Among Coleoptera species, with big sized beetles as the central figure, photos for species of dominant, rare, nominated species of new or new recorded were introduced, and also collecting sites and activities were presented.

 ,  , This study was conducted to elucidate the patterns of occurrence of bark beetles on deadwoods of Quercus serrata Fisher and Carpinus laxiflora Blume which are expected to increase due to climate change. The survey was carried out at the LTER site in Gwangneung forest in Gyeonggi Province in 2007-2008. Bark beetles were collected using emergence traps and attraction traps (funnel trap and window trap). A total of 408 beetles belonging to 12 species in two subfamilies were collected. Platypus koryoensis (Murayama) was the most abundant species. P. koryoensis and Xylosandrus germanus (Blandford) occurred mainly in deadwoods of Q. serrata. All other species, except two rare species, occurred commonly in deadwood of both tree species. Species richness and abundance of bark beetles were higher in the attraction traps than in the emergence traps, and higher in Q. serrata than in C. laxiflora. These indexes were higher in classes Ⅰ-Ⅱ or Ⅰ-Ⅲ than in classes Ⅲ-Ⅳ or Ⅳ of deadwood. Bark beetle communities differed according to years and showed a little difference between tree species.
