복숭아혹진딧물의 포식기생자인 콜레마니진디벌의 기능반응을 온도별(15, 20, 25, 30°C) 복숭아혹진딧물 밀도를 달리하여(2, 4, 8, 16, 32, 64, 128마리) 평가하였다. 모든 온도 처리에서 콜레마니진디벌은 제 3 유형의 기능반응을 보였다. 30°C에서 공격률(0.0043 day-1)은 높았지만 처 리시간(0.9268 day)은 다른 온도보다 길었다. 추정된 처리시간은 온도가 15°C에서 25°C로 증가할수록 감소하였다. 콜레마니진디벌의 24시간동 안 최대 공격률은 15, 20, 25, 30°C에서 29.1, 31.9, 59.3, 25.9이었다. 온도처리별 복숭아혹진딧물 기생률은 유사한 특징을 나타내었다. 가장 높 은 기생률은 15, 20, 25, 30°C에서 복숭아혹진딧물 32, 32, 16, 32마리에 대해 0.52, 0.54, 0.57, 0.40이었으며 25°C에서 콜레마니진디벌의 기생 력이 가장 높게 나타났다. 본 연구는 복숭아혹진딧물의 생물적 방제원으로서 콜레마니진디벌의 효율성을 여러 온도조건에서 평가하였다.

Hymenoptera is one of the most important pollinators for many crops and wild plants in Korea. Many species visit in flowers for acquirement energy source of adults, and especially bees need pollen for rearing larvae. So, bees forage on flowers more than other insects. In 2023, specice number of bees in Korea is 308 species under 6 families, 38genera. However, many bees as like bumblebees are reduced rapidly because of climate change to warm, habitat destruction as like urbanization and pestcide abuse as like Neonicotinate. For example, in Gwangreung forests there were 6 species records : Bombus ignitus, B. ardens, B. koreanus, B. ussuriensis, B. atripes and B. opulantus. But, in 2023 we could find only two species Bombus ignitus and B. ardens. Bees need protection of Habitat, healthe, and food plants by human.

Athalia japonica (Klug, 1815) is a significant insect pest of turnips in Korea. The complete mitochondrial genome of this species isolated in Korea is reported in this study, which is the first attempt to study Korean Athalia species. The circular genome is 15,662 bp in length and consists of 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and an A+T-rich region. Consistent with most members of the genus Athalia, five of the tRNA genes are rearranged from the typical ground pattern of ancestral insect gene order. Phylogenetic analyses inferred from the nucleotide sequences of 25 mitochondrial genomes indicate that the Korean A. japonica is a distinct member of the genus Athalia. This study accumulates mitochondrial genome data of A. japonica from various countries, providing useful information on mitochondrial genetic differences across geographical distances in the East Asian region.

Field surveys were conducted to collect and refine "Natural resource survey" and ecosystem research data of 23 National parks in South Korea, including Hallasan on Jeju Island and Palgongsan newly designated as national park in 2023. Among the collected data, a total of 1,538 species from 54 families of Hymenoptera insects were recorded. Within these families, the largest number of species was recorded in the family Ichneumonidae with 514 species, followed by Formicidae (118 species), Braconidae (112 species), and Tenthredinidae (135 species), exhibiting relatively high species diversity. Among the National parks, Jirisan, the first designated National park in South Korea with a relatively large area compared to other parks, recorded the highest species diversity with 618 species, while Taebaeksan recorded relatively low species diversity with 77 species. Correlation analysis between the number of Hymenoptera species and other factors revealed a statistically significant and relatively strong positive correlation (P > 0.005, R = 0.864) with the total number of insects, and a statistically significant but relatively weak positive correlation (P > 0.005, R = 0.615) with the park's area.

The North Korean sawflies housed in the Hymenoptera Collection of the Hungarian Natural History Museum are studied, with a focus on the subfamilies Athaliinae and Allantinae. Five genera and ten species of the two subfamilies are identified. Athalia indiana Benson is reported for the first time from East Asia (North Korea), and further eight species and one subspecies are discovered in the new country of North Korea: Allantus helanshanicus Wei, Li and Xiao, Apethymus kolthoffi (Forsius), A. sidorenkoi Sundukov, Athalia japonica (Klug), A. proxima (Klug), A. rosae ruficornis Jakowlew, Beleses satonis (Takeuchi), Taxonus carbonarius Takeuchi, and T. montanus Togashi. Additionally, Athalia infumata (Marlatt) syn. nov. is considered a junior subjective synonym of A. proxima (Klug). Diagnoses and photographs of the newly recorded species are provided, as well as new distributional records and brief notes on the new synonymy.

The genus Priopoda is a small group of the subfamily Ctenopelmatinae, comprising 22 species from worldwide, 10 species from the Eastern Palaearctic and 13 species from the Oriental region. This species and genus are report for the first time from South Korea. The Ctenopelmatinae comprises one of the two major radiations of parasitoids of sawflies. The approximately 1,350 species have been reported in 105 genera and nine tribes. In this study, diagnoses and photos of four unrecorded species from South Korea are provided.

The genus Helictes is a small group of the subfamily Orthocentrinae, comprising 11 species from worldwide, most species from the Palaearctic region, four species from the Nearctic, and two species from the Neotropical region. This subfamily is wide morphological variation between genera but most are readily recognizable as orthocentrines. They are generally small sized, clypeus strongly convex and malar space long. Among them, this genus is reported for the first time from South Korea. In this study, description, photographs of diagnostic characterists are provided.

We established a soybean banker plant system and evaluated the biological control effects of aphid control in bell pepper greenhouses. The soybean banker plant was B.communis breeding system and developed as an alternative aphid control agent to the most common Barley banker(Barley-Colemani). After inoculating approximately 50 soybean aphids(Aphis glycines, aphid starter population) on 2 week old soybean seedling pot after sowing and then releasing aphid parasitoids, an average of 348.7 parasitic wasps per a soybean banker plant could be produced without additional host aphid inoculation. Common recommendation for installation in the greenhouses are about 2 soybean banker plants per 330㎡ before or immediately after planting. If the number of aphids per stem is fewer than three on 2 weeks after installation of the banker plant, additional supplementation of 20~30 aphids is necessary to maintain this system for one month. When one soybean banker plant was installed per 120㎡, the aphid control effect was about 60% on the 21st day after installation.

M. pruinosa has been found on 98 families and 345 species of plants, indicating a wide host range. Since its first report in a persimmon orchard in Gimhae in 2009, it had spread to 126 municipalities over 12,429 ha. Because of powerful dispersal ability, it’s difficult to control with insecticides. Therefore, it is necessary to reduce the population density through the release of M. pruinosa’s natural enemy, N. typhlocybae. N. typhlocybae females prey on or externally parasitize the nymphs of M. pruinosa. This natural enemy was introduced from Italy in 2017 through an international cooperative project between National Institute of Agricultural Sciences and University of Padova for controlling the sporadic pest, Metcalfa pruinosa. This study reported the results of mass rearing N. typhlocybae indoors and releasing them outdoors from 2020 to 2023 in 21 regions nationwide, showing an average parasitism rate of 27.3% and an average production of 7.9 cocoons per host, suggesting the possibility of their establishment in Korea.

The genus Megastylus is a moderate group of the subfamily Orthocentrinae, comprising 38 species in two subgenera from worldwide. The subfamily Orthocentrinae is a high proportion of the genera are cosmopolitan in distribution. Orthocentrines are known as almost solitary koinobiont endoparasitoids. We report this genus for the first time from South Korea. In this study, descriptions of some new species, photographs of diagnostic characterists are provided.

Native to southern Europe, Lepisiota frauenfeldi (Mayr, 1855) is an invasive species that has been introduced worldwide through cross-border trade. It has been documented to be distributed in the Mediterranean, Middle East, Africa, and Indo-Malaya. This species, also known as Browsing ant, was first found around a warehouse in Gwangyang, Jeollanam-do, South Korea, and was probably introduced into the country via cargo. The external morphology and gene sequences were checked for taxonomic identification, and it was identified as Lepisiota frauenfeldi based on comparative analysis of the morphological classification key and NCBI data. This study is the first report of a newly invasive alien ant and provides basic data on the species, including external morphological and ecological features and sequencing results.

We analyzed trends of ants intercepted on imported plants and lumber over the past 30 years, using data extracted from the Pest Information System (PIS). There were 1,629 cases of about 112 species (5 subfamilies, 45 genera) from planting plants such as Asparagales, Alismatales, and Saxifragales, and 2,217 cases of about 86 species (7 subfamilies, 42 genera) from lumbers such as square lumber, pellets, and solid wood. For intercepted trends by continent, Asia was the most frequently detected at 91%, followed by Europe at 1% and North America at nearly 1%. Among Asian countries, Malaysia (27%) represented the highest number of interceptions, followed closely by Indonesia at 26%.

Pararhabdepyris Gorbatovsky, 1995, is a small genus in Bethylidae (Hymenoptera, Chrysidoidea), currently comprising only six valid species worldwide. A new species is described and illustrated from South Korea. Pararhabdepyris sp. nov., which appears closely related to P. paradoxus, is characterized by the combination of the following characters: the basal two-thirds of the scape are dark castaneous, coxa and femora are dark castaneous, the median and submedian metapectal-propodeal disc is rugulose, and the transverse posterior carina is straight. Images of diagnostic characteristics and an updated key to the seven world species of the genus are presented.

Vespa binghami (Hymenoptera: Vespidae) is one of the 10 species in the genus Vespa distributed in South Korea and is the only nocturnal wasp. In this study, we sequenced complete mitochondrial genome (mitogenome) of the species using the Sanger method and using Vespa-specific 30 primer sets. The length of V. binghami was 15,957 bp and the total A/T content was 80.6%. The A+T-rich region of V. binghami was 152 bp, and other Vespa species ranged from 39 bp (V. velutina) to 2,230 bp (V. v. auraria). Compared to the majority of insects, the gene arrangement of V. binghami had differences as followings: trnY-trnI-trnM-trnQ, trnN-trnE-trnS1-trnF, and trnS2-trnL1. However, all species in the genus Vespa registered in GenBank to date were composed of the same arrangement. Phylogenetic analysis using 13 PCGs and 2 rRNA genes showed the sister relationship between V. binghami and V. orientalis with the higher nodal supports.

The genus Vespa consists of 22 species worldwide, and their phylogenetic relationships are well established through adult morphology and molecular analyses. However, taxonomic studies of larvae are lacking. In this study, we provided descriptions and taxonomic keys for eight species of Korean Vespa larvae.

Chromosomal level of Korean Diadegma fenestrale (Jeju strain, JK-2023a) of genome assembly was achieved through a combined approach utilizing Nanopore long-read sequencing and Illumina NovaSeq short-read sequencing (approximately 217.2× coverage). The assembled genome spans 221.1 Mb, comprises 68 scaffolds, with most of the genome contained within 11 chromosomal level scaffolds. The completeness of the assembly is reflected in BUSCO assessment, with values reaching 99.6%. Scaffold N50 was 17.4 Mb, and GC % was 40%. RNAseq was performed using RNA extracted from larvae, pupae, and adults at various developmental stages (trimmed RNA-Seq data, 11.3 Gb), and a total of 13,544 genes were predicted by synthesizing the transcriptome information with the annotation information of five closely related species such as, Campoletis sonorensis (GCA_013761285.1), Venturia canescens (GCF_019457755.1), and Nasonia vitripennis (GCF_000002325.3, and GCF_009193385.2). Of these, 13,498 genes were identified by BLAST and are being further analyzed. Although the frequency of DfIV genome integration into the host’s 11 chromosomes varies from 0 to 32%, it was confirmed that all 62 DfIV genome fragments were inserted into the Hymenopteran host genome.

The Chalcididae belong to a medium-sized family of parasitoids in the superfamily Chalcidoidea (Hymenoptera). Chalcidids can be recognized by the swollen hind femur, the indistinct prepectus, the sharp occipital carina bordering the gena posteriorly, and the strong punctation of the mesosoma. They have been recorded parasitizing six insect orders, and several species are facultative or obligate hyperparasitoids. More than 1,500 species in 90 genera have been recorded worldwide, of which 12 species in six genera have been recorded in South Korea. As a result of taxonomic and faunal studies on Korean Chalcididae, we have found two newly recorded species, Haltichella nipponensis Habu and Dirhinus anthracia Walker, in Korea. These species were discovered using Malaise traps, Lindgren funnel traps, and observation with the naked eye in Jeonbuk, Gangwon province, and Sejong city in 2023. The genus Haltichella Spinola, 1811, is recorded in Korea for the first time. In this presentation, we provide morphological and ecological information on these species.

The box tree moth (BTM, Cydalima perspectalis Walker) is a pest that infests various plants within the Buxus genus. Although a specific parasitoid wasp species associated with the BTM has been observed in the Republic of Korea, no research on this species has been published. Here we describe the fundamental biological and morphological characteristics of this parasitoid. We placed the wasp under the genus Eriborus (Hymenoptera: Ichneumonidae: Campopleginae). Eriborus sp. parasitizes within the living host body, with one wasp emerging from each host. The parasitism rate in collected BTM populations was 33.1%. The emergence rate was 87.1%, with all emerging adults being females, resulting in a sex ratio of 0. The pupal period averaged 9.5 days, and the adult lifespan averaged 10.5 days. Eriborus sp. parasitized BTM larvae from the first to the fourth instar and reproduced by parthenogenesis. Eriborus sp. exhibited morphological differences compared with previously reported Eriborus species in Korea, particularly in the length of the ovipositor sheath. In addition, the proportion of the highest similarity in nucleotide sequences of mitochondrial cytochrome oxidase I DNA was only 94.53%, rendering species identification using GenBank’s mt cytochrome c oxidase 1 DNA sequences unfeasible. These data suggest Eriborus sp. could be used as a biological control agent for managing BTM infestations.
