상추는 수요가 연중 지속됨에 따라 재배면적과 생산량이 증가하고 있는데, 주로 생식으로 이용되며 수확간격 이 짧아 해충 다발생시 약제방제가 어려운 작물이다. 최근 검은무늬밤나방이 약제방제가 소홀한 포장에서 잎을 광포식하여 빠른 시간내에 직접적인 피해를 주고 있다. 본 연구에서는 검은무늬밤나방의 온도별 발육특성을 구명하여 방제를 위한 기초자료로 이용하고자 한다. 검은무늬밤나방은 시설재배 상추에 발생한 유충을 채집하 여 실내 사육 후 항온조건(15, 20, 25, 30℃)에서 발육단계별 발육기간을 조사하였다. 온도가 높아짐에 따라 각 태별 발육기간은 짧아지는 경향이었으며, 유충은 보통 4회 탈피하였다. 25℃에서 알기간은 2.5일, 유충기간 10.0 일, 전용기간 1.0일, 번데기기간 7.0일로 알에서 성충까지의 발육기간은 20.5일 이었다.

The genus Trichophysetis is one of the taxa that has recently undergone frequent changes in its taxonomic position. Only four species have been recorded in Korea, including synonymized Hendecasis species. Recent studies on the taxonomic classification of Trichophysetis have not addressed any species inhabiting Korea. Therefore, it is necessary to conduct a renewed morphological analysis of Korean species. In this study, we compare and analyze four Korean Trichophysetis species with one newly recorded species.

The genus Grapholita Treitschke, 1829 is a complex group belonging to the tribe Grapholitini of the subfamiliy Olethreutinae, due to their similar characteristics among the species. The genus comprises about 150 described species worldwide. The majority of described species occur in the Holarctic region. To date, eight species of Grapholita have been reported from Korea. The genus contains several notorious pests such as G. dimorpha Komai and G. molesta (Busck). Among them, G. inopinata has been doubtful in distribution. This study aim to optimize species specific sex pheromone composition/amount and establish the distribution of the pest species of the genus Grapholita in Korea.

줄수염나방아과는 나비목 중에서 가장 큰 분류군 중 하나인 밤나방과에 속한다. 분류군 내에서 날개무늬가 비슷한 경우가 있어 동정에 어려움이 많은 그룹 중 하나이다. 또한, 이 들은 산림 지역, 초지 및 물가 등 다양한 환경에 서식하며, 생활 습성에 따라 일부는 임업 및 농업에 피해가 큰 해충으로 알려져 있는 중요한 경제곤충 그룹이라 할 수 있다. 본 연구는 이와 같이 분류동정이 어려운 줄수염나방아과 곤충을 대상으로 야외채집조사, 표본제작, 생식기 해부검경 및 DNA 바코드 등을 수행하여 최종적으로 분류학적 동정지침서를 작성하고자 수행 되었다. 연구결과 19속 63종으로 정리되었다. 본 연구를 통해 확보된 DNA바코드 데이터는 정확한 바코드를 활용한 진단 및 동정 연구 등에 활용되고, 이들의 분포정보 구축, 형태적 특징 및 분자분석 연구의 기초데이터 확보를 통한 관련 분야 활성화 등에도 기여할 수 있을 것으로 기대된다.

The genus Hypsopygia was established by Hübner, 1825, with type species Phalaena costalis Fabricius, 1775. Hypsopygia is characterized by the elongated uncus and valva, and pointed saccus in the male genitalia. It consists of 105 described species (Nuss et al., 2003–2024) in the world, and 11 species have been recorded in Korea (Kim & Paek, 2020; Shin et al., 2023). In this study, we reported one newly recorded species in Korea. Illustrations of adults provided, with information of host plants of all examined species.

The genus Olethreutes, established by Hübner in 1822, is based on the type species Phalaena arcuella Clerk, 1759. Olethreutes is one of the largest group within the family Tortricidae, with more than 130 species worldwide. As of now, about 31 species of the genus Olethreutes have been reported in the Korean peninsula. The proposes of this study is to describe one new species, with three similar species form Korea.

The large copper butterfly Lycaena dispar (Haworth, 1803; Lepidoptera: Lycaenidae) has been categorized as a near-threatened species (NT) in South Korea from 2012 mainly due to limited distribution. In this study, we visited 36 sites spread across all South Korean provinces to verify the distributional range of the species and sequenced mitochondrial COI for 53 individuals from nine sites. We observed L. dispar at 15 sites in six provinces, including the two previously known provinces, indicating a southward range expansion. The in-field monitoring and genetic data collectively suggested that L. dispar does not have a limited distribution nor is it isolated, indicating that it should be reclassified as less vulnerable. Our study demonstrates that the combination of field and genetic data can provide a more reliable assessment of the stability of a species.

The clearwing moth, Synanthedon bicingulata (Staudinger, 1887), is a pest that infests various species of cherry trees. However, genetic information regarding the genus Synanthedon including S. bicingulata, is limited. In this study, we sequenced a complete mitochondrial genome (mitogenome) of the species. The 16,255 bp of S. bicingulata mitogenome differs from the typical gene arrangement formed in Lepidoptera: trnQ-trnS2-trnM-trnI arrangement between the A+T-rich region and the ND2 junction. Moreover, the genome has untranslated repetitive sequences in the intergenic space between lrRNA and trnV, as well as the CGA start codon in COI and the TTG start codon in ATP8. Similar observations are noted in species belonging to the tribe Synanthedonini within the genus Synanthedon.

The genus Argyresthia Hübner, [1825] of the family Argyresthiidae is known to comprise over 150 species worldwide. Among them, more than 70 species are recognized in the Palearctic region. The Korean fauna of the genus Argyresthia includes 11 described species to date. In this study, we report three species of the genus Argyresthia for the first time in Korea: A. brockeella (Hübner, [1813]), A. longalbella Liu, Wang & Li, 2017, and A. mala Liu, Wang & Li, 2017. All available information, images of adults and genitalia for species are provided.

The genus Grapholita, belonging to the tribe Grapholitini under the family Tortricidae, which is small to medium-sized moths ranging from 7mm to 16mm. It is a relatively diverse group in Grapholitini, comprising more than 150 species worldwide. This group is generally distributed throughout the world, with the majority of its species occurring in the Holarctic region. Some species in the genus Grapholita are known worldwide as serious pests that feed on leaves, roots, fruits and other plant parts. In Korea, the genus is known to have 8 described species up to date. In this study, we report two newly recorded species of the genus Grapholita from Korea, including a brief description and illustrations of adult and genitalia. Additionally, all available information including distribution, host plants and a taxonomic key to Korean Grapholita species is provided.

Here we review the genus Nycteola of the Nolidae (Lepidoptera). As the result of this study, we recognized already synonymized species N. costalis Sugi, 1959 of N. coreana (Leech, 1900) and newly recorded species N. dufayi Sugi, 1982. Whlie the number of Korean Nycteola species remain unchanged, the composition has been changed.

The Euonymus defoliator moth, Pryeria sinica Moore (Lepidoptera: Zygaenidae), is a pest that causes considerable damage to the Euonymus genus, especially Euonymus alatus and Euonymus japonicus. The biological characteristics of P. sinica have been studied in China, Japan, Taiwan, and the United States, but there has been no research conducted on this species in Korea. Also, P. sinica has two dormant phases in each generation, one as eggs in winter and the other as pupae in summer. Our purposes are to study the biological characteristics of Korean populations of P. sinica and to examine the effects of temperature and photoperiod on summer diapause. The biological characteristics were investigated in laboratory conditions (25 ± 1 ℃, 65 ± 1% R.H., 16L:8D) and the number of eggs in an egg mass, developmental periods and mortality rate in each larvae stage, and adults’ life span were determined. The results showed that 190.7 ± 31.64 eggs were contained in one egg mass and it took 25.57 ± 0.61 days from 1st larval stage to the pre-pupal stage. P. sinica has 4 larval stages and each stage took 4.28 ± 0.21, 6.2 ± 0.55, 6.02 ± 0.68, and 8.93 ± 0.88 days. The mortality rate of larvae peaked at 22.5% in 3rd larval stage. The adults’ life span was 4.67 ± 0.97 days in males and 4.61 ± 1.82 days in females. To study summer diapause, we divided pupae into 4 groups. Both low temperature and short daytime were effective in shortening the pupal stage. The pupal stage was the shortest in group D (122.12 ± 1.24 days), in which the initial condition was 25 ℃-16L:8D and the altered condition was 16 ℃ -12L:12D, and the longest in group A (161.92 ± 3.15 days, 25 ℃-16L:8D). These data could be utilized to propose the optimal timing for controlling the population of P. sinica.

본 연구는 검거세미밤나방(Agrotis ipsilon) 성페로몬 트랩에 혼재하여 유살되는 은무늬밤나방아과 형태적 분류와 동정법 수립을 위해, 날개 무늬의 형태계측학 분석을 실시하였다. 은무늬밤나방아과 개체는 2023년 11월 부터 12월까지 제주도 애월읍 일대에서 채집되었으며, 콩 해충으로 알려진 콩은무늬밤나방(Ctenoplusia agnata) 을 비롯하여, 다양한 농작물을 가해하는 것으로 알려진 붉은금무늬밤나방(Chrysodeixis eriosoma)의 수컷 성충이 포획되었다. 앞날개의 형태 및 무늬를 가지고 현장에서 쉽게 동정할 수 있는 형태적 특징을 도출하기 위하여, 각 성충 개체의 앞날개를 잘라 현미경 카메라로 촬영하고, 앞날개의 내횡선, 아외연선, 반점 크기 등 15개의 형질 을 측정하였다. 또한 각 형질 간의 상관관계를 분석하였으며 빈도분포를 통하여 두 종간 분리되는 형질을 파악하 였다. 최종적으로 다변량 분석법을 적용하여 두 집단이 어떻게 군집을 이루는지 분석하고, 날개형태만으로 붉은 금무늬밤나방과 콩은무늬밤나방을 구분할 수 있는 방안을 제시하였다.

This study reports the first records of four coleophorids, namely Coleophora kamchatica (Anikin, 1999), C. lativittella Erschoff, 1877, C. levantis Baldizzone & Oku, 1988, and C. citrarga Meyrick, 1934, in Korea. Additionally, the presence of two species, C. montaniella Oku & Kusunoki, 2018, and C. artemisicolella Bruand, 1855, in Korea has been overlooked in the previous checklist of the family Coleophoridae in Korea, despite there being evidence of their existence. Consequently, with these additions, the total number of known species in Korea has been confirmed to be 42, expanding from the previously identified 36 species. Diagnostic characteristics and photographs of adults and genitalia for the four newly recorded species are provided, along with evidence supporting the presence of the two overlooked species in Korea.

The family Erebidae (Lepidoptera: Noctuoidea) is known as one of the largest families in Lepidoptera, comprising about 1,760 genera and more than 24,569 described species worldwide. Within this family, the genus Plecoptera Guenée, 1852, belonging to the subfamily Anobinae, has been documented across the Palaearctic, Oriental, and Afrotropical regions. Here, we introduce the subfamily and genus for the first time in Korea, along with a new species. The diagnosis, description and photographs of adult and genitalia are provided here.

The family Pyralidae comprises over 6,000 species, and is composed of five subfamilies. Among those, the subfamily Phycitinae includes 3 genera, Addyme Walker, 1863, Calguia Walker, 1863, and Coleothrix Ragonot, 1888, with more than 3,300 species worldwide. However, several species of the genera have been erroneously stated and identified due to confusions caused by high morphological similarities. Therefore, we correct those errors through re-examinations of most of the type specimens, along with a diagnosis and table exhibiting the history of those genera. Additionally, we introduce two misidentified Korean pyralids belonging to the genus Addyme.

The family Gelechiidae (Lepidoptera: Gelechioidea) is known as one of the largest families in Microlepidoptera, encompassing about 600 genera and more than 5,000 described species worldwide. However, the genus Altenia Sattler, 1960 has been poorly studied in Korea, with only one known species. Here we introduce a new species, Altenia parascriptella sp. nov., from Korea, providing photos of adults and genitalia for both sexes, along with diagnostic characteristics.

Vietnam is a country in Southeast Asia, long from north to south, with temperate, subtropical, and tropical climates in different parts of the country. Based on the results of two years of insect surveys in the subtropical and tropical regions of Vietnam, we conducted a comparative analysis of the species diversity of the Noctuoidea (Insecta: Lepidoptera) in the two survey areas, Bach Ma National Park and Protected Forest in the Vạn Xuân region. In addition, the host flora of the identified moths were analysed to determine the differences in host communities.
