  • Two species of Scopula, S. asthena Inoue, 1943 and S. tenuisocius Inoue, 1942, were newly recorded from Korea. Scopula asthena can be distinguished by the bipectinate male antennae and whitish wings with four blackish dots on each wing. This species is similar to S. superior (Butler, 1878) but differs in the large blackish discal dots on both wings. Scopula tenuisocius can be distinguished by its whitish forewing with light grayish, dentate antemedial line, short-line shaped discal dot and line light grayish, weakly rounded, dentate postmedial line, and whitish hindwing with a blackish discal dot and light grayish, undulating medial lines. Scopula tenuisocius is similar to S. floslactata (Haworth, 1809) but the species can be distinguished by the thinner and blackish subterminal line of the forewing that appears minutely dentate along the line. To date, 41 species of the genus Scopula are known in Korea.

  • Two geometrid species, Mixochlora argentifusa (Walker, 1861) and Scopula tsushimana Kaneko, 2018, were newly recorded from Korea. Mixochlora argentifusa, a species of Geometrinae, is characterized by dark greenish, inverse triangular central fascia with a large lunular discal dot and a thick subterminal line of the falcate forewing and band-shaped medial and subterminal lines of the hindwing. Scopula tsushimana, a species of Sterrhinae, is characterized by dark blackish, slanted, dentate ante- and postmedial, and subterminal lines with a black, minute discal dot of the forewing and a relatively thick, blackish antemedial line and strongly undulating postmedial and subterminal lines of the hindwing. We provide diagnosis, description of adults and immatures, if available, and illustrations of the adults, and male and female genitalia.

  • Fine structure of the dry adhesion system in the tarsal appendages of the jumping spider Plexippus setipes (Araneae: Salticidae) with examined using field emission scanning electron microscope (FESEM). The jumping spiders have the distinctive attachment apparatus for adhesion on smooth dry surface without sticky fluids. They attach to rough substrates using tarsal claws, however attachment on smooth surfaces is achieved by means of a tuft-like hair called a scopula. All eight legs have the scopulae with a pair of claws on the tip of feet, and each scopula is composed of two groups of setae that are capable of dry adhesion on smooth surface. The apex of each seta is flattened pad bearing many specialized adhesive setules on one side. The cuticular sensillae are interspersed at the dorsal surface of the seta. It has been revealed by this research that the contact area of the setule is always a triangular shape, and these cuticular surfaces are connected by the elongated stalks from the underlying setae. Moreover, adhesion between the numerous setules and the setae was prevented by the microscopic hairs, since these were interspersed on the upper side of the setae.

  • Carchesium polypinum and Vorticella campanula were collected in freshwater ponds and reservoirs on Jindo Island and other places in Korea. These two vorticellids are newly recorded in Korea. The two species are described using live and silver impregnated cell observations, morphometry, line drawings, and microphotographs. Characterizations were based on the following diagnostic features: Carchesium polypinum was observed mainly as a funnel to fanshaped colony, basically dichotomous branching pattern, discontinuous spasmoneme, subconical shaped zooid, J shaped macronucleus, ventrally positioned single contractile vacuole, and pellicular striation with 61-80 rows between the peristomial lip and aboral ciliary wreath, and 18-30 rows between the aboral ciliary wreath and scopula. Vorticella campanula was conspicuously characterized by the broadly bulged peristomial lip, wide conical shaped zooid, J or S shaped macronucleus, ventrally positioned single contractile vacuole and pellicular striation with 64-75 rows between the peristomial lip and aboral ciliary wreath, and 27-41 rows between the aboral ciliary wreath and scopula. We provide redescriptions of two well-known vorticellids with detailed drawings and descriptions of oral ciliatures from Jindo Island and other places on the Korean peninsula.

  • The cuticle of spider's exoskeleton is a hydrophobic and non-adhesive material, but the jumping spiders have the distinctive attachment apparatus for adhesion on smooth dry surface without sticky fluids. We have examined the whole tarsal appendages of the jumping spider, Plexippus setipes with using scanning electron microscope to reveal the fine structural characteristics of the dry adhesion system. All eight legs have the scopulae with a pair of claws on the tip of feet. Each scopula is composed of two groups of setae that are capable of dry adhesion on smooth surface, and the hook structure of the claw is advanced to move on the rough surface. The setae toward the bottom of the tarsal segment are densely covered by numerous setules on the underside which broadened from middle to distal portion. It has been revealed by this research that the contact area of the setule is always a triangular shape, and these cuticular surfaces are connected by the elongated stalks from the underlying setae. It is likely that the nano-scale structures including a triangular depression and a longitudinal groove on each setule could functionate when the spider detach its feet from the substrate.

  • Forty-eight fungal isolates were collected from the Korean traditional maejus and twenty-eight isolates of them were identified to be a hyphomycetous fungus(three genera and 20 species) Aspergillus flavus, A. flavus var columnaris, A. oryzae, A, oryzae var effusus, A. terreus, Scopula­riosis brevicaulis, Penicillium botryosum, P. gorlenkoanum, P. griseo-purpureum, P. citrinum, P. miczynskii, P. gaditanum, P. turolense, P. funiculosum, P. rubicundum, P. godlewskii, P. jensenii, P. roqueforti, P. volguense, P. verrucosum. Various 14 species of Penicillium were isolated from maejus, but all of them were not considered to be involved in the maeju fermentation. Otherwise, S. brevicaulis was especially collected from the maejus of various located areas, but were also related to the good quality of maejus under labratory conditions. A. flavus, A. oryzae P. tulolense, and P. funiculosum were also observed to be involved in the process of maeju.

  • This survey was conducted to illustrate insect pests and their natural enemies in soybean fields in Honam area. A total of 23 pest species in 13 families and 13 species of natural enemy were observed during 2002 to 2003. Delia platura, Medythia nigrobilineata, Spodoptera exigua and Aphis glycines occurred relatively with high population densities during the early growth stage of soybean. Dolycoris baccarum, Riptortus clavatus, Nezara antennata, Piezodorus hybneri and Halyomorpha halys began to occur between mid July to early August and lasted until the harvest time. Lepidopteran insect pests, Leguminivora glycinivorella, Pleuroptya ruralis, Scopula missaria, Macdunnoughia purissima and Spodoptera litura occurred significantly in late August in soybean field. Natural enemies of soybean insect pests observed in this survey were seven parasitoids, five predators, and an entomopahogenic fungus. Two egg parasitoid species for R. clavatus, two parasitoid species for P. ruralis, and five natural enemy species (including parasite, predator and entomopathogenic fungi) for either S. litura or A. glycines were identified, respectively. Among them two egg parasitoid species, Gryon japonicum and Ooenyrtus nezarae for R. clavatus, for and one parasitoid species for P. ruralis, that belong to Bethylidae, were new to Korea.
