  • 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.

  • From the result of this study for the materials collected in Mt. Changbai-shan, six species of the family Noctuidae, Pangrapta marmorata Staudinger, P. griseola Staudinger, Ctenostola sparganoides (Bang-Haas), Cucullia amota Alpheraky, Xestia albonigra (Kononenko), and X. speciosa $(H\ddot{u}bner)$, are reported for the first time from China.

  • The genus Ephedrus Haliday, 1833 is a large taxon of Aphidiinae, consisting of 48 valid species in the world. This genus is considered to be important as a biological control agency, which includes solitary koinobiont parasitoids on aphids. One of its interesting characteristics is both male and female have 11-segmented antennae. In previous study, this genus was subdivided into three subgenus, Breviephedrus, Ephedrus and Fovephedrus, based on molecular and morphological characters. In this study, one Ephedrus species is firstly recorded from South Korea. Since it has been collected from Geumsan-gun in 2005 and deposited as dried specimen at Naturalis Biodiversity Center in Netherland, we recently confirmed it. Description and illustrations of the E. lacertosus are provided.

  • A unicellular green alga was axenically isolated from the Port of Jeongja, Ulsan, Korea. Morphological, molecular, and biochemical analyses revealed that the isolate belonged to Heterochlorella luteoviridis. This is the first report of this species in Korea. The microalgal strain was named as H. luteoviridis MM0014 and its growth, lipid composition, and biomass properties were investigated. The strain thrived over a wide range of temperatures ($5-30^{\circ}C$) and withstood up to 0.5 M NaCl. The results of gas chromatography/mass spectrometry analysis showed that the isolate was rich in nutritionally important polyunsaturated fatty acids. Its major fatty acids were linoleic acid (35.6%) and ${\alpha}$-linolenic acid (16.2%). Thus, this indigenous marine microalga is a potential alternative source of ${\omega}3$ and ${\omega}6$ polyunsaturated fatty acids, which are currently obtained from fish and plant oils. Ultimate analysis indicated that the gross calorific value was $19.7MJ\;kg^{-1}$. In addition, the biomass may serve as an excellent animal feed because of its high protein content (51.5%). Therefore, H. luteoviridis MM0014 shows promise for applications in the production of microalgae-based biochemicals and biomass feedstock.
