Insect fauna were surveyed in 2011 at Ungok wetland, Obeygol, located in Gochang, Jeonbuk, Korea. In total, 149 species belonging to 11 orders and 57 families were surveyed. Among them, Lepidopterans composed 23.5% (35 species) of the total insect numbers surveyed, comprising the most abundant group, and followed by Coleoptera, Hemiptera, and Odonata with a composition of 22.1% (33 species), 17.4% (26 species), and 10.1% (15 species), respectively. Bothrogonia japonica Ishihara was the most dominant species, and followed by Gastrophysa atrocyanea Motschulsky and Celastrina argiolus (Linnaeus). Phytophagous insects accounted for 60 percent of the total species. Dominance index was the highest in spring by 0.21. Diversity, richness, and evenness indices were the highest in summer by 4.07, 11.84 and 0.96, respectively. In the study area, the legally-protect species were grouped into five groups; 9 export-restricted species, 17 endemic species, 28 indicator species, 1 climate-sensitive biological indicator and 3 southern characteristic species. Additionally, twenty forest insect pest species were surveyed, belonging to 5 orders and 15 families. Therefore, it is required to conduct long-term monitoring and appropriate management based on the ecological characteristic of the habitats to continuously conserve and maintain of wetland.

Among non-timber forest products, Tricholoma matsutake is a high value added item. Many countries, including Korea, China, and Japan, are doing research and technology development to increase artificial cultivation and productivity. However, the production of T. matsutake is on the decline due to global warming, abnormal temperatures and pine tree pest problems. Therefore, it is necessary to identify trends in domestic and foreign research on T. matsutake, respond to preemptive research and development to preserve the genetic resources of T. matsutake and increase its productivity. Based on the correlation between keywords in the high frequency keywords, it was observed that microbial clusters of T. matsutake are mainly found in Korea. The main focus in China has been the pharmacology studies on the ingredients of T. matsutake. The main focus in Japan has been on preserving the genetic diversity and species of T. matsutake. Thus, future domestic studies of T. matsutake will require pharmacological studies on the ingredients of T. matsutake and on its genetic diversity and species conservation. In addition, unlike China and Japan, genetic keywords did not appear in Korea at high frequency. Therefore, Korea will have to proceed with research using modern molecular biology techniques.

Finger millet is more nutritious than other and millets and widely cultivate in tropical regions of the world. Furthermore, it is more tolerant against biotic and abiotic stresses such as pest, drought and salt. For this reason, finger millet is one of the putative crops to introduce and cultivate on reclaimed land and prepare the global climate exchange in Korea. In present study, genetic diversity and structure of different populations of finger millet from Africa and South Asia was examined at molecular level using newly developed EST-Simple Sequence Repeat (EST-SSR) markers. In total, 46 primers produced 292 alleles in a size range of 100-500 bp and mean Polymorphism Information Content (PIC) and Marker Index (MI) were 0.372 and 1.04, respectively. 46 primers showed polymorphism and 21 primers were identified as having a PIC value above 0.5. Principal coordinates analysis and the dendrogram constructed out of combined data of both markers showed grouping of finger millet accessions to their respective area of collection. The 156 accessions were more classified into four groups, such as three groups of Africa collection and one group of Asia. Results of present study can be useful in identifying diverse accessions and management of this plant resource. Moreover, the novel SSR markers developed can be utilized for various genetic analyses in this species in future.

Diadegma fenestrale is known as a parasitoid of the potato tuber moth, Phthorimaea operculella. The potato tuber moth, Phthorimaea operculella (Zeller) is one of the most destructive pest of potatoes. Also, we found this species attacking the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae). Ratio of parasitism is 20-30% and cocoon of lepidopteran was parasitic ichneumonid species after 3 days. This species and the genus Diadegma are recorded for the first time from Korea. In this paper, description of the parasitoid and photographs of the diagnostic characteristics are provided.

Two species of Cryptophlebia: C. nota Kawabe and C. ombrodelta (Lower), are reported from Korea for the first time. This is in fact the first record of Cryptophlebia from Korea, as the previous Korean records of the genus were based on one species, Cryptophlebia hematoma Diakonoff, currently assigned to Thaumatotibia Zacher. Photos of the superficial and genital features are provided for the two Korean species of Cryptophlebia and their distribution and host plants are summarized. Cryptophlebia ombrodelta is recognized as an adventive species in Korea and a potential pest on leguminoseous crops.

Three species of Acrolepiopsis: A. issikiella (Moriuti, 1961), A. japonica Gaedike, 1982, and A. postomacula (Matsumura, 1931), are recorded from Korea for the first time. Acrolepiopsis issikiella is characterized by having the white costal strigulae and a large dorsal patch on the forewing. Acrolepidopsis japonica is the smallest congener in Korea. Acrolepiopsis postomacula is the only Korean species of Acrolepiinae associated with Hosta. Distributions and larval biology of the three species are summarized. Two species, A. issikiella and A. japonica, are potential pest species of yam-cultivating farms in Korea. Superficial and genital features of the species, if available, are illustrated.

Ranging from a variety that a consumer to purchase and consume, and a variety with high quality and pest resistance, sustaining biological diversity as well as hiring global experts who understand breeding policy, it tightly maintains relationship with producer, consumer, and exporter to promote superior species for customized export to exporting country. By carrying out researches on cost saving and how to shorten the period of apple to cultivate, it consolidates its stance as a competent apple exporting country of apple and pear with high competetiveness. In order to compete against apple and pear of New Zealand, farmers argue that they need budget and researchers also argue that "No money, no research." Due to certain limit of governmental budget support, it is believed that it is time to fund our own way to promote apple research center. To come up with the best apple production, all of those who associates with apple such as farmers, researchers, government, exporters, and consumer should do their best to enhance the apple and pear industry.

The genus Grapholita Treitschke, belonging to the tribe Grapholitini, comprises over 150 species worldwide with the majority occurring in the Holarctic region. However, in other regions, only few species are reported owing to a lack of collection and taxonomic study. The genus includes important agricultural pests worldwide that feed on several plants in the families Fabaceae and Rosaceae. In Korea, a comprehensive taxonomic study is required as only eight species have been reported to date. In this study, two species of Grapholita Treitschke, G. latericia Komai, 1999 and G. pallifrontana (Lienig & Zeller, 1846) are newly recorded from Korea. We provide redescribed and illustrated adult and available genitalia. Additionally, all available information, including collecting localities, distribution, host plants and biological characteristics is presented.
