This study presents a new record of an acronictine species from Korea, including descriptions, illustrations, and diagnostic characteristics. Additionally, the CO1 barcode data of the newly recorded species is compared with the global barcode reference at the species level. New data on the recently recorded species has been obtained from this study. This information will aid in the prompt identification and preparation for potential pest outbreaks.

Eriocraniidae is a microleidopteran family (Lepidoptera: Eriocraniidae) that includes six genera and distributed to the Holarctic region. The larvae of this family are known leaf miners, typically infesting Betula and Ouercus. Herein. the first reord of the genus Dyeriocrania Spuler, 1910 in Korea is presented, including the previously undscribed species. Adult and female genitalia are provided based on illustrations.

A taxonomic study was conducted on Spilonota Stephens, 1834 in Korea. As a result of the research based on materials from Incheon National University two new species; S. samseong Choi, Bae & Nasu, and S. laticucullusa Choi, Bae & Nasu from Korea. This study provides a brief description of the new Spilonota species in Korea, as well as comparisons with similar species and illustrations of adult and genital morphology.

The genus Paragabara is recognized as a member of the subfamily Boletobiinae, with six species in the Eastern Palaearctic. In Korea, three species of this genus are known. Konoenko et al. (2010) designated a lectotype for P. flavomacula (Oberthür, 1880) and described a new species, P. curvicornuta. In this study, the misidentification of the Korean P. flavomacula as P. curvicornuta has been corrected. Additionally, one newly recorded species, P. curvicornuta, is reported from Korea. In total, four Paragabara species are recognized in Korea. All available information, images of adults, a checklist, and male and female genitalia, etc., are provided.

Bombyx mandarina (Lepidoptera: Bombycidae), the presumed ancestor of the domesticated silkworm B. mori, has long been a subject of study to illustrate the geographic relationships in connection with origin of B. mori. We sequenced 100 mitochondrial genomes of B. mandarina collected from South Korea and Japan and these were combined with public data. Phylogenetic and population genetic analyses showed that all individuals collected in South Korea, except one individual from Inje, formed a strong group together with northern China and some individuals of southern China. This group was placed as the sister group to B. mori strains, suggesting that this group could have been served as an immediate progenitor for B. mori. For further robust inference more analysis is underway.

The family Glyphipterigidae comprises more than 500 described species worldwide. In Korea, only 11 species of 4 genera under 2 subfamilies recorded. In this study, a total of 16 species were discovered, including 5 new recorded species. The new recorded species discovered are as follows; Glyphipterix euleucotoma Diakonoff & Arita, 1976, G. gamma Moriuti & Saito, 1964, G. gemmula Diakonoff, 1976, G. mikadonis Arita & Owada, 2006 and G. semiflavana Issiki, 1930. All available information, adults and genital images structures are provided.

This study was conducted to review the genus Bucculatrix Zeller, 1839 belonging the family Bucculatricidae. In Korea, only three species have been reported to date (Park, 2013; Lee and Jeun, 2022; 2023). A total nine species were identified in Korea in this study. Among them. two species, Bucculatrix sp. nov.1 and B. sp. nov.2 was described as new to science. Also four species: B. duanwuia Liu, 2020, B. tsurubamella Kobayashi, Hirowatari & Kuroko, 2010, B. demaryella (Duponchel, 1840) and B. comporabile Seksjaeva, 1989 are reported for the first time from Korea. These species were identified by visiting Osaka Metropolitan University and comparing the specimens. Available information, host plants, images of adults and genitalic structures, and DNA barcode for the species are provided.

As climate changes and global trade volume increases, the spread of invasive alien species accelerates. Early prevention before occurrence is crucial for invasive pest control. Therefore, this study modeled the current and future potential distribution of the tomato leafminer(Tuta absoluta) (Meyrick) (Lepidoptera: Gelechiidae), the most significant pest affecting tomatoes, in Korea. This pest primarily feeds on Solanaceae crops and can cause extensive damage, resulting in 50-100% loss of crops in greenhouses or fields. While previously unreported in Korea, it invaded China in 2017, indicating a potential threat to Korea. The potential distribution of the tomato leafminer in Korea under current and three future climate scenarios (SSP1-26, SSP3-70, SSP5-85) was predicted using the MaxEnt model. Additionally, elevation and land cover were incorporated as abiotic factors considering the ecological characteristics of the pest.

Spodoptera eridania and S. ornithogalli (Lepidoptera: Noctuidae), which are polyphagous pests that damage various crops such as tomatoes and beans are regulated quarantine species that are highly likely to invade South Korea. Therefore, it is crucial to promptly and accurately identify the presence of S. eridania and S. ornithogalli in crop fields to effectively eradicate as a regulated quarantine species. In this study, we developed a loop-mediated isothermal amplification (LAMP) assay, which allows for rapid in-field identification. To develop the LAMP　assay, we selected target species-specific genomic regions from the whole-genome sequences of one target and 13 other lepidopteran species. We validated each five and six primer sets that consistently produced positive reactions in S. eridania and S. ornithogalli, respectively. To test the sensitivity of the each locus, LAMP reactions were performed using various reaction times using crude DNA, which was extracted from various types of adult tissues. All sensitivity tests were also successful.

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.

뒷흰가는줄무늬밤나방은 쌀, 밀, 옥수수와 같은 농작물에 피해를 주는 해충이다. 본 연구에서는 국내 뒷흰가는줄무늬밤나방의 미토콘드리아 게놈(15,314b)을 분석하였다. 13개의PCG와2개의 rRNA (13,376bp)를 연결한 서열을 사용한 계통발생 분석 결과, 뒷흰가는줄무늬밤나방과 멸 강나방 사이의 가장 높은 노드 수치로 자매분류군을 형성하였다. 밤나방상과(Noctuoidea)의 각 과(Noctuidae, Euteliidae, Nolidae, Erebidae 및 Notodontidae)들은 가장 높은 노드수치로 단계통을 형성하였다.

뒷흰가는줄무늬밤나방은 열대거세미나방 성페로몬 트랩에 지속적으로 상당수 유인되는 있는 비래해충이지만, 국내에서 뒷흰가는줄무늬 밤나방에 대한 정보는 매우 미흡한 실정이다. 향후 뒷흰가는줄무늬밤나방에 대한 다양한 연구 진행을 위해서는 대량사육에 관한 선행연구가 요구 된다. 본 연구에서는 뒷흰가는줄무늬밤나방 대량사육을 위한 인공사료 2종의 개별 및 조합 공급과, 집단 또는 개체사육이 발육 및 산란에 미치는 영향을 분석하였다. 기존 나방류 사육용 2종의 인공사료에 대한 발육특성을 비교한 결과, 검거세미나방 인공사료 제공시 유충은 높은 생존율과 빠른 발육을 보였으나, 번데기 무게는 감소하였다. 2종 인공사료 간 산란수에는 유의한(P < 0.05) 차이가 없었다. 집단사육은 개체사육에 비해 유 충의 빠른 발육과 번데기 무게 및 생존율 감소를 야기하였다. 또한, 먹이와 사육 방법에 따라 암컷과 수컷에 미치는 영향이 달랐다. 뒷흰가는줄무 늬밤나방의 대량 사육을 위해서는 부화 직후 검거세미밤나방 인공사료를 이용해서 집단 사육한 후, 2령 혹은 3령 이후에는 개체사육하는 것이 효 율적일 것으로 판단되었다.

벼밤나방[Sesamia inferens (Walker, 1856)](나비목: 밤나방과)은 벼 줄기를 가해하는 해충이다. 본 연구는 국내 몇 지역에서 벼밤나방의 연 중 세대수를 추정하였다. 북위 38° 부근의 세 지역에서 벼밤나방 성충이 성페로몬트랩에 포획되었다. 이는 국내 모든 지역에서 벼밤나방이 서식하 는 것을 나타냈다. 조사된 지역 대부분에서 단일사인곡선의 유효적산온일도 모델로 추정된 세대별 성충 발생 시기는 관찰된 성충 세대의 발생 시기 와 차이가 없었다. 이 모델을 사용하여 추정된 월동유충은 성충 마지막 세대로부터 유래할 가능성이 있다고 추정되었다. 중남부지역에서 가을동안 벼 포장에서 채집된 유충들을 25°C에서 사육하였을 때, 번데기의 약 70%가 용화전 유충 탈피를 보이지 않았다. 경남 고성에서 3월초에 채집된 유 충은 25°C 사육에서 유충 탈피 없이 용화하여 이 지역에서는 주로 마지막 유충 영기로 월동할 것으로 추정되었다. 모든 결과를 종합하여 벼밤나방 은 북위 38° 부근 지역에서는 주로 2세대, 북위 35.3° ~ 37.3° 사이 지역에서는 3세대가 경과할 것으로 결론지었다. 별도로, 시토크롬 c 산화효소 1 유전자의 염기서열을 분석한 결과, 성페로몬트랩에 포획된 종의 35%가 다른 종이었고, 이들은 형태적으로 벼밤나방과 혼동되지 않았다.

Erebinae, a subfamily within the family Erebidae, represents one of the largest classification groups in Lepidoptera. This taxonomic group exhibits remarkable ecological diversity and astonishing predator defense adaptations. Erebinae possesses what is presumed to be the most sensitive tympana (hearing organs) among Lepidoptera, allowing them to evade predators such as bats. Furthermore, they have distinctive hindwings, in contrast to their inconspicuous forewings, which they can suddenly expose as a strategy to escape danger from predators. The classification of the subfamily Erebinae is based on molecular studies conducted by Zahiri et al. (2012). However, despite these efforts, there is no single external feature that can reliably identify all Erebinae, and the boundaries of this group remain somewhat unclear. Many specimens have yet to be thoroughly studied, and numerous genera are still awaiting placement within the phylogenetic framework.

The Blastobasidae is microlepidopteran, narrow-winged moth and account of more 500 species among 23genera worldwide. This family is defined by the following characteristics: i) presence of antennal pecten in head; ii) Rs and M1 separate in the hindwing; iii) valva with well-developed digitate saccular processus in male genitalia; iv) aedeagus with a band-like internal sclerite.

The family of Pterophoridae, also called ‘Plume moth’, is distributed all around the world. More than 1,100 species have been studied and reported in the most recent world catalogue, and it has been discovered 34 species from Korea. The reason why they are called Plume moth is that they have a distinct shape of wings, which makes them easily distinguished. This group have a 6－40mm wingspan, mostly have two-pronged forewings and three-pronged hindwings. Interestingly, their resting posture is T-shaped with the narrow forewings held perpendicular to the body, while the hindwings tucked under or folded within the forewings. They have slender bodies with long, fragile legs, and also have three types of color : plain white, mottled gray or brown. Pterophoridae has unique morphological characteristics, and it is an interesting group for us to look over them in general.

곡나방과는 날개 편 길이 10~20mm 정도의 미소나방으로, 전 세계적으로 11속 100여종이 알려진 작은 분류군 이다. 이들은 단풍나무, 자작나무 등의 잎을 가해하며, 1령 유충은 잠엽성 생태를 보이고 그 이후에는 기주식물의 잎을 둥글게 잘라 은신처를 만들고 그 안에서 생활하는 독특한 생태를 보인다. 국내에는 현재 3종이 알려져 있으 며, 인접 국가의 현황을 보면 잠재적인 종이 좀 더 분포할 것으로 예상된다. 본 연구를 통해 국내 곡나방과를 소개 하고 추후 연구의 기틀을 마련하고자 한다.

그림날개나방과는 날개편 길이 10~12mm 정도의 작은 나방으로 파좀나방아과와 그림날개나방아과로 구성 된다. 파좀나방아과는 앞날개 외연 중앙에 삼각형의 흰색 점이 있다는 형태적 특징이 있지만 종간 특징이 매우 유사하다. 그림날개나방아과는 앞날개에 반짝이는 금속성 무늬가 있으며 주행성이라는 특징이 있다. 그림날개 나방과는 세계적으로 약 500여종이 기록되어있으며 중국은 57종, 일본은 41종이 기록되었지만 한국은 11종만이 알려져 있어 추가적인 연구 가능성이 충분한 분류군이다. 따라서 본 연구는 최신화 된 한국산 그림날개나방과의 정리를 목표로 한다.

좀날개나방과(Eriocraniidae)는 나비목 중 4번째로 분화한 분류군으로 잘 알려져 있으며, 현재 5속 29종으로 이루어져 있다. 성충의 머리에는 큰턱의 흔적기관이 남아있으며, 흡관이 관찰되어 흡관아목에 속한다. 출현시기 는 3~4월의 초봄에 나타나며, 주로 아침에 활동하는 것으로 알려져 있다. 국내에는 Eriocarnia 속에 속하는 자작나 무좀굴나방(Eriocrania sparrmannella) 한 종만이 알려져 있으며, 인근 국가의 분포 현황을 보았을 때 잠재적인 종이 분포할 것으로 예상된다. 본 연구에서는 Eriocraniidae의 서식환경 및 생태를 소개하여 추후 연구의 기틀을 마련하고자 한다.
