This study aims to systematically investigate the insect diversity within the distinct coastal grassland and mountain habitats of East Busan, Busan Metropolitan City. The objective is to gather foundational data that will inform natural environment conservation plans and contribute to policy formulation. Employing a comprehensive collection approach, we utilized trapping nets, pitfall traps, and flying insect traps to capture a broad spectrum of insect species. The investigation identified a rich diversity of 132 species across 9 orders and 52 families. Coleoptera emerged as the most prevalent order with 13 families and 41 species, followed by Diptera with 8 families and 24 species, and Lepidoptera with 9 families and 21 species. To assess the biodiversity and structure of these communities by habitat type, we applied several biodiversity indices: the Shannon-Wiener index (H'), Margalef index (R), and Pielou evenness index. Coastal grasslands exhibited an H' of 3.153, R of 11.08, and a Pielou evenness of 0.371; coastal mountains showed an H' of 2.922, R of 13.02, and a Pielou evenness of 0.202. These metrics reveal no significant differences in diversity and evenness between the two habitats. The endangered Copris tripartitus was notably observed in coastal grasslands, alongside 20 species classified as Least Concern (LC) in the National Red List across both habitats. The comparative analysis of biodiversity and evenness levels across coastal grassland and mountain areas highlights the ecological significance of both habitats in supporting a diverse insect fauna. The detection of endangered and LC species within these areas emphasizes the critical need for ongoing monitoring and the development of effective conservation strategies tailored to protect Busan's coastal ecosystems. The findings underscore the necessity of conducting periodic surveys to monitor faunal changes and inform conservation efforts actively. By ensuring the continued protection of insect diversity, these efforts will play a pivotal role in maintaining the ecological integrity of coastal areas, thereby supporting broader environmental conservation objectives.
Understanding the landscapes and the elements that make up the landscapes can help us understand the entire natural ecosystems and biodiversity. Landscape ecology has been studied since the past. however, many studies are conducted on single landscapes, and comparative studies between landscapes are few. We compared insect species diversity and community structure within a single plant community across landscapes and habitat. Additionally, identify environmental factors that affect diversity. Our results showed that above-ground and below-ground insect communities were clearly distinguished. Additionally, species diversity was high below-ground in all landscapes. Insect community structures across landscapes did not differ in above-ground. However, below-ground, the urban was differentiated from the forest and agricultural land. We identified the urbanization indices GMIS and PHBASE as factors responsible for these difference.
This study was conducted to identify changes of insect compositions and diversity after construction of an onshore wind farm. We investigated insect fauna and compositions between a grassland deforested by the construction and a forest located at Yeongdeok and Yeongyang, Gyeongsangbuk-do, Korea. Insects were collected using a sweeping net and light trap. A total of 11 orders, 50 families, and 246 species, and 1,076 individuals were collected at study sites. By taxonomic group, Lepidoptera species were the most frequently found with 141 species, 417 individuals (38.8%), followed by Hymenoptera (20.6%), Hemiptera (16.2%), and Orthoptera (12.3%). There were also significant differences in insect species and community compositions between sites. Creating open-field deforested forests are beneficial for some insect groups such as Hymenoptera and Orthoptera. Our results suggest that deforesting by the construction of an onshore wind farm might affect the composition and diversity of insects. Results of this study provide basic data for research on onshore wind farms.

In the forest ecosystem, trees are important components among many life forms, supporting biodiversity. This biodiversity is found not only in living trees but also in dead trees, where they provide rich environment for dead wood-associated organisms. Among saproxylic invertebrates, insects play pivotal roles in dead wood ecosystem and comprise of a huge proportion of diversity. In this study, we categorize Quercus dead wood into three decay classes, and seek to understand the association of saproxylic insect assemblages and different decay classes. Using emergence traps, we examine how many insect species and individuals appear in each decay class, and how insect assemblages change across the full range of decompositional stages of Quercus dead wood. This will highlight the importance of retaining various dead wood to conserve saproxylic biodiversity.
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.
This study was done to develop environmental risk assessments and a biosafety guide for insect-resistant genetically modified rice at a LMO (Living Modified Organism) isolation field. In the LMO quarantine area of Kyungpook National University, the species diversities and population densities of non-target insects found on insect-resistant genetically modified rice (Bt-T) resistant to Cnaphalocrocis medinalis and on non-GM rices (Dongjin-byeo and Ilmi-byeo) were investigated. The Bt-T event was therefore evaluated under field conditions to detect possible impacts on the above ground insects and spiders. The study compared transgenic rice and two non-GM reference rices, Dongjinbyeo and Ilmi-byeo, at Gunwi in Southern Korea in 2016 and 2017. A total of 9,552 individuals from 51 families and 11 orders were collected from the LMO isolation field. In the three types of rice fields, a total of 3,042 individuals from the Bt-T, 3,213 individuals from the Dongjin-byeo, and 3,297 individuals from the Ilmi-byeo were collected, respectively. There was no difference between the population densities of the non-target insect pests, natural enemies and other insects on the Bt-T and non-GM rices. The data of insect species population densities were subjected to principal component analysis (PCA), which not distinguished among the three varieties, GM and non-GM, reference cultivar in all cultivation years. However, PCA results were clearly separated the samples based on the cultivation years. These results suggest that insect species diversities and population densities during plants cultivation are determined by environmental factors (growing condition and seasons) rather than by genetic factors.
The Ministry of Environment in Korea published 'The Compilation of National List of Indigenous Insect Species ofthe Korean Peninsula' in 1996 including 11,853 species. The National Institute of Biological Resources (NIBR) originallycompiled the national species list of insects to establish a national inventory of endemic biological assets with the joinedefforts from all distinguished Korean taxonomists since 2008. For the convenience of taxonomists participating in theproject concurrently, the NIBR has developed the NIBR inventory description method and inventory system from 2008to 2017. Until September 2017 in this study, the NIBR has established the national insect inventory of 17,493 speciesincluding Collembola. The insect fauna of the Korean Peninsula comprises 579 families from 30 orders. The largest ordersare Coleoptera (114 families, 4,489 species), Lepidoptera (72 families, 3,868 species), Hymenoptera (63 families, 3,581species), Hemiptera (88 families, 2,102 species) and Diptera (79 families, 2,128 species). The fractions of the main insectorders in the fauna of the Korean peninsula correspond to those in the Holarctic temperate zone.
The members of the genus Flavivirus are noteworthy, as they cause infectious diseases in humans, such as Zika, denguefever, yellow fever, West Nile, and Japanese encephalitis. Due to the increased awareness of the public health risk posedby flavivirus-infected mosquitoes, mosquito collections were performed in six urban parks of South Korea, as the parksare designated for human recreation but also provide suitable habitats for mosquitoes. We examined the diversity andabundance of mosquito species and conducted molecular diagnostics for the detection of flavivirus infections. Monthlycollections were carried out in each park from March to August in 2017. A total of 4,851 mosquitoes (5 genera and13 species) were collected using BG-sentinel traps and then investigated for flavivirus infections. Pathogenic flavivirusinfections causing human diseases were not observed in the field-collected mosquitoes. However, insect-specific flavivirus(ISF) infections were detected in several mosquito pools. ISF has been previously known to enhance or suppress the replicationof medically important flaviviruses in co-infected mosquito cells. In this study, partial sequences of ISF were analyzed.However, further studies are needed in order to determine its genetic characterization and biological function in vivo.
