We analyzed comparatively the ground beetle communities of 1993 and 2023, with 30 year interval, in broadleaf and coniferous stands of the Gwangneung forest, a biosphere reserve in South Korea. 2,906 individuals (53 species, 38 genera, and 15 families) were collected from broadleaf stands and 1,782 individuals (36 species, 32 genera, and 14 families) from coniferous stands in 1993. The dominant species was Synuchus cycloderus in both stands. In 2023, 1,682 individuals (110 species, 78 genera, 21 families) were collected from broadleaf stands and 990 individuals (92 species, 67 genera, 22 families) from coniferous stands. In 2023, the dominant species were Eucarabus (Parhomopterus) sternbergi sternbergi in broadleaf stands and Coptolabrus jankowskii jankowskii in coniferous stands. Species richness (R'), species evenness (E'), species diversity (H'), and dominance (DI) were all higher than in broadleaf (R'=15.472, E'=0.336, H'=1.601, and DI=0.371) and coniferous (R'=13.756, E'=0.369, H'=1.324, and DI=0.326) forests in 2023.

Vespidae are social insects and crucial predators that prey upon various insects. In particular, Vespa velutina nigrithorax, as a representative predator of honey bees, inflicts huge economic damage on apiary. Therefore, it is essential to investigate the national distribution of vespid wasps. In this study, collection was made, in 73 study sites, using hornetluring traps and malaise traps in Gangwon-do, Gyeonggi-do, Gyeongsang-do, Chungcheong-do, and Jeju-do from 2019 to 2022. As a result, a total of 24,974 individuals of 24 species, 5 genera, and 2 subfamilies were collected, with the largest number of species collected in Gangwon-do (22 species, 5 genera, and 2 subfamilies). Also, Vespa simillima simillima (38.2%), Vespa crabro flavofasciata (25.1%), Vespa crabro flavofasciata (23.8%), Vespa velutina nigrithorax (27.5%), and Vespa simillima xanthoptera (54.6%) are the dominant species in each province, respectively. Species richness (R') and species evenness (E') were highest in Gyeonggi-do (R'=2.712, E'=0.978), and species diversity (H') was highest in Gyeongsang-do (H'=2.981). Dominance was highest in Jeju-do (DI=0.719). Herein, we provide basic data needed in development of vespid damage management systems using regional sampling data and forest geospatial information in the study area.

The Gwangneung arboretum, affiliated to the Korea Forest Research Institute, was established in 1987 and it became the Korea National Arboretum (KNA) in May 24, 1999. The entomological collection of KNA currently holds a total of 510,365 specimens of 6,849 species including more than 330 type specimens of Lepidoptera, Hemiptera, Hymenoptera, and Coleoptera are deposited. As the results of recent systematic studies by KNA entomologists, 67 new species were described, and 108 species were newly recorded from Korea and other countries. Not only we have conducted taxonomic studies but also have broaden our research boundary to natural enemy surveys for pine wilt disease vectors, plant and insect interaction, and exotic insect species monitoring. In this presentation, we would like to briefly introduce current entomological researches of KNA in the hope of future collaborations with other entomologists.

Monochamus saltuarius Gebler are the insect vector of the pine wood nematode (PWN), Bursaphelenchus xylophilus (Steiner & Buhrer) mostly in the mid-northern areas of South Korea. In 2017, we installed sentinel logs to lure efficient parasitic wasps of the vector and to evaluate ecological characteristics of parasitoids in prior to the development of biological control strategy for the PWN transmitting insect vector. As a result of the survey, we found Spathius verustus Chao (Hymenoptera: Braconidae) as a predominant parasitoid with the highest parasitism rate among six species of larval parasitoids. The parasitism rate was higher along the edge (0m of the forest depth) of the survey sites than the inner sides (20m and 40m of the forest depth). Also, the parasitoid showed highest parasitism rate in late-May at one of Gapyeong_sites, where was supposed to be the oldest infected areas. Lastly, the parasitism rate along the trap heights was higher at height of 0m than the 1.8m above the ground.

In Korea, two species, Anoplophora chinensis and Anoplophora glabripennis, have been recorded until now. Recently, outbreaks of Anoplophora spp. were reported locally in Seoul, Ulsan, Incheon, Gimhae, and Jeonju from 2015 to 2017. In this study, Anoplophora spp. were collected in the four regions, Ulsan, Incheon, Gimhae, and Jeonju, and their morphological and molecular characteristics were compared with those of Anoplophora spp. collected from several local regions. Twelve COI sequences of the Incheon/Gimhae/Ulsan/Jeonju populations in A. glabripennis were identical to KY357648, KY357652, and KY357651, and two COI sequences of Ulsan populations in A. chinensis were identical to AB439163. These sequences were generated from Chinese and Japanese Anoplophora samples by foreign researchers, suggesting the possibility of the invasion of Chinese and Japanese populations of Anoplophora spp. into Korea.

Two species in Monochamus (Coleoptera: Cerambycidae) are wellknown vector species of the pine wood nematode (PWN) in South Korea. In 2018, the surveys using sentinel logs with two Monochamus species larvae were made from early June to last September in Pinus densiflora forests of Pohang city, South Korea. The experiments were repeated 10 times in order to investigate parasitism patterns of the larval parasitoids of M. saltuarius and M. alternatus. Three plots were chose at interval distance of 20 m (0 m, 20 m, 40 m) from the edge to the center of the forests (i.e. forest depths) in one damage area of the pine wilt disease for each of three different locations. For each time of the exposure ten sentinel logs were hung along the tree heights (i.e. sentinel logs positions) (height: 0 m, 1.8 m, 3.6 m, 5.4 m, 7.2 m). As the results of the surveys six larval parasitoids in total were identified, and most abundant parasitoids were Spathius verustus and Cynopterus flavator. Analyses showed that the parasitism rate on larvae of two Monochamus species was not affected according to forest depth, but the parasitism rate was the highest in the third plot. Also the parasitism rate was the highest at 5.4 m height of a tree. Lastly, parasitisms rate on M. alternatus was higher than that of M. saltuarius.

Monochamus saltuarius Gebler (Coleoptera: Cerambycidae) is a well-known as vector species of the pine wood nematode (PWN) in the northern areas of South Korea. In 2017, larval parasitoids of M. saltuarius and their parasitism patterns were investigated in Pinus koraiensis forests with consideration of sentinel logs positions (height: 0 m vs. 1.8 m), distances from the edge to the center of the forest (0, 20, 40, 60, 80m), and damage degrees of the pine wilt disease (infested area, buffer area, and uninfested area). In total six of larval parasitoids were collected: Spathius verustus, Sclerodermus harmandi, Cynopterus flavator, Heydenia testacea, Heydenia sp., Braconidae sp. The parasitism rate to larvae of M. saltuarius larvae was not affected by sentinel log positions. However, the parasitism rate was significantly higher in infested areas compared to the buffer and uninfested areas. In the infested area, the parasitism rate was increased with distance from forest edges.
