  • This study focused on the isolation and characterization of wild yeasts in Korea. The yeasts were identified by phylogenetically analyzing the D1/D2 domains of the 26S rDNA regions. Consequently, we identified seven strains, NNIBRFG856, NNIBRFG3732, NNIBRFG3734, NNIBRFG3738, NNIBRFG3739, NNIBRFG5497, and NNIBRFG6049, which were confirmed to be Kabatiella microsticta, Pichia membranifaciens, Candida vartiovaarae, Candida sake, Debaryomyces hansenii, Candida railenensis, and Schwanniomyces polymorphus, respectively, all of them being new in Korea. Morphological and cultural characteristics of these yeast species were investigated. None of the strains formed ascospores or pseudomycelia. Moreover, these yeasts grew in a pH range of 4-8. NNIBRFG3732, NNIBRFG3738, NNIBRFG3739, NNIBRFG5497, and NNIBRFG6049 were halotolerant or halophilic, and NNIBRFG3732, NNIBRFG3734, and NNIBRFG6049 grew in vitamin-free medium. NNIBRFG3732, NIBRFG3739, and NNIBRFG6049 grew at 35 ℃, but not at 40 ℃.

  • The genus Bitomus Szepligeti, 1910 (Hymenoptera: Braconidae: Opiinae) is known to parasitize in mining flies (Diptera: Agromyzidae), of which four species are recorded in Korea. Bitomus was revised by Fischer (1987, 1994) and recently treated by Papp (1978, 1981) in Korea. Bitomus is distinguished from other genera by the immovably joined second-third or fourth metasomal tergites, forming a carapace. In this study, Bitomus indicus is recognized for the first time in Korea. This study provides a diagnosis, description, distribution, and diagnostic illustrations.

  • Mold contamination is one of the detrimental factors affecting sawdust media-based shiitake cultivation in greenhouses. During mold monitoring of indoor air of greenhouses, several fungi were isolated. Among them, Aspergillus pulverulentus and Cosmospora butyri were found to be new in Korea and Lecanicillium psalliotae and L. antillanum were known in Korea without taxonomic validation. In this study the morphological characteristics and phylogenetic analysis based on the internal transcribed spacer (ITS) rDNA region or ${\beta}$-tubulin gene of the four identified species were described.

  • Three species of the order Perciformes collected from coastal waters of Cheju Island, Korea were documented with photographs, all of which are newly known to Korea. Nemipterus bathybius Snyder, 1911 of the family Nemipteridae is distinguished by seven anal soft rays and the most upper ray at the caudal fin elongated. Cirrhitichthys aureus (Temminck et Schlegel, 1842) of the family Cirrhitidae (New Korean name: Hwangbokdom-kwa), is characterized by the five to six light black spots on the dorso-Iateral sides, 12 dorsal soft rays and a dorsal fin without spots and bands. Parapercis aurantiaca D$\ddot{o}$erlein, 1884 of the family Pinguipedidae, has several taxonomic characters. The dorsal spines and the soft rays of the dorsal fins were connected without a notch. The five to six dark yellow bands with the same size of eye length were shown on the lateral region. A new Korean name Kinsilkkoridom is proposed for the Nemipterus bathybius, and Cirrhitichthys aureus, Hwangbukdom, and Parapercis aurantiaca, Hwangssangdonggari.

  • Spathius ibarakius Belokobylskij et Maeto, which belongs to the Spathius exarator species group (Hymenoptera: Braconidae: Doryctinae) was found as an ectoparasitoid of the first- and second-instar larvae of the citrus longhorned beetle, Anoplophora chinensis ($F{\ddot{o}}rster$) from Gwangneung, Pocheon, Korea. The discovery of this braconid wasp was made during the survey for parasitoids of the Asian and citrus longhorned beetles by using the sentinel log method. We herein describe diagnostic characters of S. ibarakius, including those of the male, and also provide illustrations. In addition, we present a host list of Korean species belong to genus Spathius.

  • One hundred and sixteen seed samples of 16 different crops were tested by routine seed health testing methods. Seeds of rice, soybean and barley were found to be associated with 18, 15 and 7 species of fungi, respectively. Discoloration and spotting of various kinds were observed in rice seeds. Epicoccum purpurascens, Pyricularia oryzae and Trichoconiella pedwickii were higher in these discoloured than in normal seeds of rice. Macrophomina phaseolina, the charcoal-rot fungus is a new record for soybean in Korea. Seeds of sesame were infected by 13 fungi Alternaria sesami, A. sesarmicola and Corynespora cassiicola were detected predominantly. Twenty one species of fungi were detected in seed samples of 12 commercial vegetable crops. Alternaria, Colletotrichum and Fusarium were found predominantly. Some seed samples of commercial vegetable crops were heavily infected with pathogenic fungi and showed heavy seed and seedling rot.

  • Rhipicephilus sanguineus (Latreille 1806) the brown dog tick, is one of the most widely distributed ixodid ticks in the world, however, there was no report for the discovery of the species in Korea. Specimens unfed or partly fed were collected from the dogs rearing in the livestock farms and the pastures near the farms located in Kyunggi-Do, Chungchong-Namdo, Cholla-Pukdo and Cheju-Do, in summer seasons during 1981 to 1984. The specimens were examined at the Institute of Veterinary Research in Anyang and were identified as R. sanguineus. The morphological characteristics observed by means of the scanning electron microscope were presented with some SEM microphotographs. As. R. sanguineus is firstly discovered to occur in Korea, a total of 20 species of ticks belonging to E: genera, such as, Argas, Amblyomma, Boophilus, Dermacentor, Haemaphysalis, Hyalomma, Ixodes and Rhipicephilus, has now been recorded.

  • We presented detailed morphological descriptions of the eggs, larvae and juvenile of Acanthaphritis unoorum based on specimens collected with bongo nets from Korean waters during the period May 2017-July 2018. We collected 18 individuals including eggs (n= 4, 0.77-0.85 mm in egg diameter), preflexion larvae (n= 6, 4.11-6.31 mm in standard length, SL), flexion larvae (n= 4, 6.60-7.82 mm SL), postflexion larvae (n= 3, 8.94-13.46 mm SL), and one juvenile (n= 1, 14.67 mm SL). The mitochondrial (mt) DNA 16S rRNA sequences of the eggs, and the cytochrome c oxidase subunit I (COI) sequences of the larvae were identical to those of A. unoorum adults (genetic distances <0.01). The A. unoorum larvae and the juvenile that we collected were morphologically similar to those of Dactylopsaron dimorphicum, but the A. unoorum specimens were readily distinguishable by the presence of lateral melanophores. This is the first record of A. unoorum in Korean waters. We propose a new Korean name for A. unoorum: "O-ri-bu-ri-nuntung-i".

  • This study is a record of ethnomedicinal knowledge in Begumganj province focussed on medicinal plants and their local uses for primary health care. The aim was to document and preserve the ethnomedicinal knowledge used by traditional healers of Begumganj upazila, Bangladesh, to treat human diseases and evaluate the relative efficacy of the medicinal plants. The uses of medicinal plants were documented as an ethnomedicinal data sheet using direct observation, field interview, plant interview and group interview techniques from December 2012 to January 2014 in the study area. Data were collected from 98 traditional healers through a questionnaire survey and analyzed through informant consensus factor and fidelity level. This study revealed comprehensive relationship among various diseases and families, forms and parts of plants and modes of preparation. Overall, 75 plant species under 71 genera of 47 families were documented, which are used to treat 41 diseases. Data analysis revealed that 41.33%, 14.67%, 36% and 8% of the medicinal plant species were herbs, shrubs, trees, and climbers, respectively. Leaves were the most used parts, followed by stem, root, fruit, bark, latex and rhizome. The most frequently treated diseases were dysentery, rheumatism and skin diseases. This is the first ethnobotanical survey, which recorded the importance of medicinal plants in Begumganj upazila, Bangladesh. This study can contribute to preserving the indigenous knowledge on the traditional use of medicinal plants in this region and new drug development with attracting future generations towards traditional healing practice.

  • In May 2020, a single larval specimen (5.14 mm in total length) was collected from the southeastern sea of Jeju Island of Korea using bongo net. The specimen was identified as Lepidotrigla longifaciata based on mitochondrial DNA cytochrome c oxidase subunit I sequences. The morphological traits of the L. longifaciata larva are as follows: a long snout, a large mouth, large fan-shaped pectoral fins, and black melanophores scattered on the abdominal cavity and nape. We propose the new Korean name 'Gin-meo-ri-dal-jae' for this species, which was first discovered in Korea.
