The genus Dichaeta Megen is a small group of acalyptratae flies belonging to the subfamily Notiphilinae in the family Ephydridae. Up to now, six species are recorded only in the Northern Hemisphere. Adults are small flies and typically found in the sedge and grass around lentic and lotic aquatic systems, and larvae feed on saprophytic microorganisms. Adults are readily recognized with the following peculiar morphology of the male abdomen: fourth abdominal tegite with some markedly long setae along its posterior margin, and these setae sometimes extend beyond the length of the posterior apex of the abdomen; modified fifth abdominal tergite produced posteriorly, either forming a slender and elongated tube with two to three larger and elongated terminal setae. This genus is recorded for the first time in the Korean fauna based on the discovery of a nominated species, Dichaeta caudata (Fallén, 1813). Diagnoses and figures about the firstly recorded species are provided herein.

The genus Brachydeutera Loew, 1862 comprises a small group of Acalyptratae flies belonging to the subfamily Ephydrinae of the family Ephydridae. So far, 16 described species have been recorded worldwide, and although the genus occurs in all fauna regions, it is most diverse in the subtropics and tropics, particularly in Africa and Asia. This genus has been recorded for the first time in the Korean fauna based on the discovery of a nominated species, B. meridionalis (Rondani, 1856). This paper provides the diagnosis, the morphological features, and an ecological photograph of the first recorded species.

Flies of the genus Scatella are small and dark-gray, and many species have distinctive whitish spots on their gray wings. Most species are found in damp environment, such as the borders of marshes, seashore areas, swamps, lakes, ponds, streams, and paddy fields. The Korean shore fly genus Scatella Robineau-Desvoidy has been taxonomically noted. A total of five species have been identified: S. calida Matsumura, 1915, S. nipponica Miyagi, 1977, S. obsoleta Loew, 1861, S. paludum (Meigen, 1830), and S. tenuicosta Collin, 1930. This is the first report of S. calida Matsumura, 1915 from Korea. A key to the Korean Scatella species and photographs of the external features have been provided.

The genus Opius Wesmael, 1835 (Hymenoptera: Braconidae: Opiinae) generally parasitizes larvae of Agromyzidae, Anthomyiidae, Drosophilidae, Tephritidae, Ephydridae and Cecidomyiidae, of which 32 species are recorded in South Korea. In China, seven new species of the genus Opius have been known. Among them, Opius crenuliferus Li & van Achterberg, 2013 is reported for the first time in South Korea. Specimen was collected by sweeping in West Daeshin-dong, Busan, Korea. In this study, description, and diagnostic illustration of O. crenuliferus are provided.

The genus Phaedrotoma Foerster, 1862 (Hymenoptera: Braconidae: Opiinae) parasitize in larvae of flies, Tephritidae, Agromyzidae, Ephydridae, Anthomyiidae, Scathophagidae, and Drosophilidae, of which 12 species are recorded in South Korea. As results of our survey, Phaedrotoma rugulifera Li et al. (2013) and Phaedrotoma vermiculifera Li et al. (2013) are reported for the first time in South Korea. Those specimens were collected by sweeping. Descriptions, and diagnostic illustrations of P. rugulifera and P. vermiculifera are provided.

Habitat, reproduction and feeding habit of endangered fish Koreocobitis naktongensis from Jaho stream, Gyeongsangbuk-do, Korea were investigated from March 2010 to June 2011. This species inhabits at the upper and middle parts of stream, which were composed of cobbles and pebbles bottom. The current velocities in these microhabitat were 5~10 cm/sec and depth were 50~110cm. The sex ratio of female to male was 1 : 0.92. It is presumed that the spawning season is from May to June when water temperatures were 17 ~ 20$^{\circ}C$. The average number of mature eggs in ovary were about 22,643 (15,909~30,323), mean egg diameter was 0.87${\pm}$0.05mm. K. naktongensis fed mainly on Chironomidae (IRI, 72.0%) and Ephydridae (26.9%) of Diptera.

This study was conducted to monitor and prevent outbreak of insect pestsin dredged soil dumping area after completion of dredging construction in Masan City. Monitoring was carried out using tent trap, colored sticky trap, and CDC light trap. A total of 217,073 individuals belonging to 23 species from 10 families in 3 orders were collected. In overwintering survey using tent trap, 3 species were collected. 2 species (Leptocera fuscipennis (Haliday) and Ephydra japonica Miyagi) of them were outbreak species. In color sticky trap, more than 96% of total individuals were comprised of five species: Urolepis maritima Walker (43%), E. japonica (19%), Fucellia sp. 1 (13%), Philotelma sp. 1 (10%), and Homalometopus sp. 1 (9%). In CDC light trap, three dominant species were Homalometopus sp. 1 (91%), Glyptotendipes tokunagai Sasa (6%), and L. fuscipennis (1%), representing about 98% of the total. To prevent damage caused by outbreak of insect pests, we carried out ecological control methods such as covering the fresh soil in outbreak area, using light trap, pumping up water and so on, minimizing use of thermal fogging and insect growth regulatorwhen the insect pest population was rapidly increasing.
