Parasitic rate of A. orientalis was calculated and compared with parasitic rate five years ago, immediately after release, and parasitic rate was also compared according to the distance away from the release point. In addition, haplotype of A. orientalis was confirmed and the association with life cycle characteristics was decided. The survey was conducted in 2022 and 2023. The parasitic rate of release point in Buyeo increased significantly from 3.6% in 18 years to 91.21% in 22. And the parasitic rate by distance from release point is 91.21% (200m), 44.46% (12km), and 65.75% (46km). At all points of survey, only haplotype C and D were found, and there was no significant difference between haplotype C and D in the parasitic rate and sex ratio.

The Eurytoma appendigaster species-group is a second large group within the genus Eurytoma Illiger found in the Palearctic region. This group comprises 44 species by Zerova, but in Korea, only one species, E. appendigaster (Swederus), has been previously reported. They are well-known for their predation on phytophagous insects, mainly the genus Tetramesa which is belonged to the family Eurytomidae and associated with grasses (Poaceae). In this study, we report seven species of the appendigaster species-group from Korea for the first time. Also, key to Korean species of appendigaster species-group and photos of diagnostic characteristics are provided.

Eurytomidae Walker, 1832 are relatively medium-sized group in the superfamily Chalcidoidea with approximately 1600 species of three subfamilies and 73 valid genera. In Palearctic region, more than 600 species have been recorded, and only 11 species are recorded in South Korea. In this presentation, we report 21 eurytomid species including one subfamily, three genera and 10 species new to South Korea.

Tineobius Ashmead, 1896 is a relatively small group in the family Eupelmidae. It can be distinguished by the following characters: head with conspicuously lengthened maxillary palpus, mesotibia without apical groove, gaster with deeply emarginate syntergum and filiform ovipositor sheaths. Most species of Tineobius were recorded from Afrotropical, Australasian and Oriental region. However, in Palearctic region, only one species (Tineobius tamaricis Ribes & Fusu) is discovered from Spain by Fusu & Ribes (2017). In this study, the genus Tineobius is reported from South Korea for the first time, with two newly recorded species. Also, a key to South Korean species of Tienobius, diagnoses and photographs of the diagnostic characteristics are provided.

Eupelmidae Walker, 1833, belongs to the superfamily Chalcidoidea, with more than 1,000 described species within48 genera worldwide. They are distinguished from other families as following characters: females and some males withlarge and undivided mesopleuron; gaster subsessile; male antenna with seven funiculars and only single anellus.Most species of this family are idiobiont ectoparasitoids or predators of the immature stage of Coleoptera, Homoptera,Lepidoptera, Neuroptera, Orthoptera and even other Hymenoptera, or some species are endoparasitoids of eggs of Araneae,Dictyoptera, Hemiptera, Lepidoptera, Orthoptera and Phasmida.In this study, history, descriptions, photos of habitus and a key to genera and species of South Korean Eupelmidaeare provided.

Monodontomerus Westwood is widely distributed genus in Torymidae Walker, and it consists of 41 species with one fossil species. In Palearctic region, 18 species are recorded, each 5 species are known from Japan and China, and 8 species from Russia. However, in South Korea, only two species are known as follows: Monodontomerus dentipes (Dalman) and M. minor (Ratzeburg). In this study, four species are newly reported and a key to South Korean species of the genus Monodontomerus Westwood, diagnosis, photos of characteristics are provided.

Leucospidae Walker are a relatively small family in Chalcidoidea, and they consist of four genera and about 140 species in worldwide. In neighboring countries, 12 species are known from China and four species are known from Japan, but only one species is known from South Korea by Paik (1974). In this study, Leucospis yasumatsui Habu is reported for the frist time from South Korea. A key to South Korean species of the genus Leucospis Fabricius, diagnosis, photos of characteristics and distribution from South Korea are provided.
