With the expansion of China’s territory, the distinguished character system of Chinese language continue to spread to its surrounding areas, which includes various ethnic areas in the south of china. As a subject to the influence of Chinese character. In the history of Vietnam, the influence of Chinese character begins from North genus period. During the thousand years of the north genus had the policy of feudal forces of northern china, the Chinese characters are different in form afferent Vietnames language, the Vietnamese people with their own different ways to accept, borrowed and used Chinese characters in Vietnam as a second language. Though, the Vietnamese no longer use Chinese characters now, but Chinese characters in Vietnamese culture and history still plays an important role.

This study was conducted to clarify the faunistic data for the genus Olethreutes from North Korea, which is one of the biggest genus in the family Tortricidae. Eventhough there have been several investigations by previous researchers, no comprehensive study on the genus from North Korea has been conducted to date. In the present study, a total of 19 species of the genus Olethreutes were recognized from North Korea. All available information for the species, including the host plants, synonymies, and distributional ranges, is also provided.

In North Korea, the Tortricidae has been poorly studied until Byun et al. (1998) reviewed 350 species from Korea, including 63 species of Tortricinae and 40 species of Olethreutinae. Then Razowski (1999) presented a checklist of 358 species of Tortricidae from Korea, including 176 species of the North Korean Tortricidae with mostly based on the avaialble materials in Poland and previous literatures. Later, a serial studies on the family Tortricdae of North Korea with the material deposited in the Hungarian Natural History Museum provided several additional data for the North Korean tortricid fauna (Byun 2009; Byun 2011a; Byun 2011b; Byun 2011c; Byun et al. 2007) During the course of the study on the Tortricidae of North Korea deposited in Hungarian Natural History Museum, the author found three species of Olethreutes for the first time from North Korea. Of them, Olethreutes aviana Falkovitsh is also newly reported to the Korean peninsula. The aim of the present study is to report the three species of Olethreutes as new to North Korean fauna. In the present study, three species of the genus Olethreutes: O. aviana Falkovitsh, O. obovata (Walsingham), and O. orthocosma (Meyrick), based on the material deposited in the Hungarian Natural History Museum, are reported for the first time from North Korea. Among them, O. aviana Falkovitsh is recorded as new to the Korean peninsula. Photographs of the adults and genitalia of the species are presented.

Genus Spilonota is a small group of the family Tortricidae, including over 29 described species worldwide (Brown, 2005). Most larvae of the genus feed on various plant families including Pinaceae, Rosaceae, Leguminosae, Betulaceae, Salicaceae, and Juglandaceae, with economical importance (Park, 1983, Zhang & Li, 2005). Even though this genus has been relatively well investigated in East Asia: five species from South Korea (Byun et al., 2009); ten species from China (Zhang & Li, 2005); eight species from Russian Far East (Kuznetsov, 2001); thirteen species including four unidentified species from Japan (Kawabe, 1982, Oku, 2003), it has been very poorly studied from North Korea with only two recorded species to date (Razowski, 1999, Byun et al., 2009) The aim of the present study is to clarify the fauna of the genus Spilonota from North Korea, including two new records, based on the material deposited in the Hungarian Natural History Museum, Budapest, Hungary (HNHM). In the present study, the author examined all available material from North Korea. In this study, four species of Spilonota are recognized. Among them, two species, Spilonota lechriaspis Meyrick, 1932 and Spilonota ocellana (Denis et Schiffermüller, 1775), are reported for the first time from North Korea. A key to the species is provided. Photos of adults and the genitalia are provided with brief comments on the distribution.

The genus Tetramoera Diakonoff (Tortricidae: Olethreutinae) is small group, including 6 species worldwide (Brown, 2005). Among them, 4 species, T. flavescens Kuznetsov, T. isogramma Meyrick, T. paragramma Meyrick, and T. schistaceana Snellen, have been described from the Oriental region in the early 20th century. And the other two species, T. gracilistira Turner, and T. leptalea Diakonoff were reported from Australia and South Africa respectively. During the course of the study on North Korean Tortiricidae based on the material deposited in the Hungarian Natural History Museum, Budapest, Hungary, one species of the genus Tetramoera Diakonoff was found. In the present study, the genus Tetramoera Diakonoff, is reported for the first time from the Korean Peninsula. Also a new species, Tetramoera bongwaensis sp. nov., is described as new to science. Photographs of the adults and male genitalia are presented.
