This study analyzed quarantine inspection records for imported ginger seed rhizomes (Zingiber officinale) in Korea from 2015 to 2024, utilizing the Pest Information System (PIS) of the Animal and Plant Quarantine Agency. The aim was to characterize the occurrence and trends of plant-parasitic nematodes associated with ginger planting and to provide management implications for risk-based phytosanitary measures. A total of 1,327 cargo consignments were analyzed. Plant-parasitic nematodes were found in 496 consignments (37%), comprising 13 different nematode taxa. Two regulated taxa, Meloidogyne spp. and Pratylenchus spp., were identified in 149 cases, leading to the destruction of the corresponding consignments in accordance with quarantine regulations. The remaining 11 taxa (347 cases) were classified as non-quarantine pests and were released. Root-knot nematodes (Meloidogyne spp.) were the most prevalent, accounting for over 80% of all detections, with M. incognita (191 cases), Meloidogyne spp. (128 cases), and M. javanica (68 cases) being the most common. Although Gunsan Port had the highest number of consignments, the detection rate was relatively higher at Incheon Port, suggesting possible differences among production areas or exporters. Overall, the findings indicate that imported ginger seed rhizomes can serve as a pathway for nematode introduction. To reduce the risk of field-level transmission, it is recommended to enhance pre-export lot management and implement nematode suppression measures, along with providing post-import guidance for growers, such as hot-water treatment or approved dips before planting.

Jeju Island has been facing to threat of high-risk invasive pests from tropical areas. To protect domestic agriculture from those invasive pests, APQA has conducted a regular monitoring program on Jeju Island. We collected especially phototactic heteroceran pests by light bucket trap and identified them using their superficial appearances, and also mitochondria COI gene. As a result, a total of 24 families, 136 genera, 193 species, and 819 individuals were collected from around Jeju Island in 2023. Among them, two unidentified epidopteran pests, Palpita sp. (Crambidae) and Xyrosaris sp. (Yponomeutidae) were collected. In the present study, we report two unidentified micro-lepidopteran pests using superficial characteristics and mitochondria COI gene.

Xyrosaris Meyrick, 1907 is a small genus of the family Yponomeutidae, established by Meyrick (1907) for its type species Xyrosaris dyropa Meyrick, 1907. A total of nine species were recognized in the world. Most of species of the genus have been described by Meyrick at the early 20th century. Up to date, X. lichneuta Meyrick, 1918 has been reported from Korea. In the present study, we review the genus Xyrosaris from Korea, with two new species: X. sp.1 and X. sp.2. Key to species, illustrations of adult, male and female genitalia, diagnosis and short description are provided.

The genus Pachynoa Lederer, 1863 reported 13 species in the world. This genus was established by Lederer, 1863 have been treated within the genera Pitacanda Moore, 1886 by Hampson, 1896 and Hypermeces Turner, 1933 by Shaffer et al., 1996. Species of the genus Pachynoa are mostly distributed from India and Taiwan to Solomon island. In this study, the genus Pachynoa is newly recorded in Laos with two species, Pachynoa xanthochyta (Turner, 1933) and Pachynoa thoosalis (Walker, 1859). These species are redescribed with illustrations of the adults and the genitalia, and their distribution is updated.

The genus Coptotriche belongs to leafmining family Tischeriidae, comprising about 60 species in the world. They live in inside leaves during immature stage; larvae feed on tissue of the leaf, producing mining trace. The pupa also spend in the mine, and emerge to become a adult from the mine. In Korea, two species, C. angusticollella and C. heinemanni, are reported and are known as pest about Rosa multiflora and Rubus crataegifolius respectively. In the present study, we review three species of genus Coptotriche in Korea with a new species. Brief descriptions and illustrations of the adults, male and female genitalia, larvae, pupae, and host plants are provided.

The Pyraustinae is one of the large subfamily in Crambidae. In Korea, more than 60 species in 20 genera of the Pyraustinae have been reported. Recently, Demobotys pervulgalis (Hampson, 1913) and Ecpyrrhorrhoe dissimilis (Yamanaka, 1958) were recorded by Choi et al. (2015). Among of the Pyraustinae, the genera Callibotys and Sinibotys were established by Munroe and Mutuura (1969). In this study, we report two species of genera Callibotys and Sinibotys from Korea for the first time, with a newly recorded genus Callibotys. Illustrations of adults, male and female genitalia, description are provided.

The genus Meganola (Nolidae, Nolinae) was established by Dyar (1898), with the type species Meganola conspicua Dyar, 1898, from America (Type locality: Texas, Colorado, Arizona). This genus comprises 80 species described in the Palaearctic and Oriental region. In this study, genus Meganola Dyar is reviewed from Korea, with description of a new species. We redescribed 12 species and one new species. Illustrations of adults and genitalia of all Korean species are provided, with a key to the genus of Meganola based on the male genitalia.

The genus Yponomeuta Latreille belongs to the family Yponomeutidae, with over 75 described species worldwide. This genus is distributed mainly in the Palaearctic Region, comprising 42 species. In Korea, a total of 16 species have been reported from Korea. This genus is reported by Park (1983), with seven species in Illustrated Flora & Fauna of Korea Vol. 27. Bae & Byun (2003) reported four newly recorded species of this genus: Yponomeuta kanaiella, Y. montanatus, Y. sociatus, and Y. yanagawanus. Byun (2009) listed a Korean Micro-Lepidoptera, recording 12 Yponomeuta species, with a newly recorded species Y. solitariellus. Sohn et al. (2010) and Lee & Park (2016) added two species: Y. anatolicus and Y. cinefacta. In the present study, we reported three newly recorded species of Yponomeuta, including adults and genital photographs, host plants, distribution and short descriptions.

The family Tischeriidae belongs to superfamily Tischerioidea, comprising four genera and 115 species. Tischeriidae is known as a leafminer, Tischeriid larvae feed between the leaves of the host plants through all instars. In Korea, two genera and four species have been recorded. recently, Sohn (2007) reported one species and Byun et al (2009) arranged checklist of Tischeriidae. In the present study, we provided checklist of this family, including a newly recorded species from Korea. Brief descriptions of species and illustration of adult and genitalia are provided.
