Neung-Ho Ahn,Yang-Seop Bae,Euiyoung Kang 한국응용곤충학회 2014 한국응용곤충학회 학술대회논문집 Vol.2014 No.04
A tineid moth, Gaphara conspersa (Matsumura, 1931) is newly reported in Korea. Gaphara conspersa is myrmecophilous, associated with some species of ants such as Lasius (Lasius) japonicus, L. (Dendrolasius) spp., Polyrhachis spp., Camponotus spp., Pristomyrmex punctatus was known in Japan. The larva lives in a 8-shaped or gourd-shaped flat case are made of soil and sand. Larva scavenges food, dead ants and shed skins of ant larvae that are carried out by ants. Females lays eggs around the nests (Maruyama et al., 2013). In this study, Gaphara conspersa (Matsumura, 1931) was found for the first time from Korea. The larvae were collected in the ant nests at Mt. Cheonggye, Geumto-dong, Seongnam City, in 22. May 2013 and 16. June 2013. The larval cases have three level sizes (small, middle and large) were found at the same time. Figures of the adults, larvae and pupae, are given in this study.

Mine and gall makers among Lepidoptera are found in the family Gracillariidae. The genus Borboryctis Kumata et Kuroko, 1988, have 2 species B. euryae Kumata et Kuroko and B. triplaca (Mayrick). B. euryae is known a gall maker of Eurya spp. In this study, Borboryctis euryae Kumata et Kuroko, 1988 feeding on Eurya japonica Thunb. and E. emarginata Makino (Theaceae), is reported for the first time from Is. Jeju and Geoje, Korea. The host plant, Eurya spp. an evergreen tree, is widely distributed in East Asia including Korea. The early instar larva makes linear mine near the surface of the leaves and mature larva makes gall on the leaves of the host plant. Larval frass ejected behaviour were not observed. The mature larva makes a light brown spindle-shape cocoon on the somewhere of the host plant, mainly edge of the leaf. The descriptions and figures of the male and female genitalia, mine, gall, larvae and pupae in immature stages, are provided.
Subfamily Oecophyllembiinae Real et Balachowsky (Lepidoptera, Gracillariidae) new to Korea

Oecophyllembiinae moths are small leaf mining gracillariid subfamily which is consisting of 34 species in 6 genera on the world, and their wing expanse about only 5-10mm. Since Kumata (1998) redefined subfamily Oecophyllembiinae, and Vari et al. (2002) treated Oecophyllembiinae as a synonym of Phyllocnistinae. Kawahara et al. (2011) analyzed, however, the grouping Oecophyllembiinae together with Phyllocnistinae is supported weakly or not at all, but a sister-group relationship could not be rejected. Also, because of their character distinctions on hind wing venation and the larval thoracic spiracles, we would like to follow Kumata (1998) distinguished Oecophyllembiinae from Phyllocnistinae. In thisstudy, Eumetriochroa hederae Kumata, 1998 feeding on Hedera rhombea SIEB. et ZUCC. (Araliaceae), is reported for the first time from Goheung, Korea. The host plant Hedera rhombea is a species of ivy which is native to coast of East Asia and some islands of East Asia include China, Taiwan, Japan and Korea. Larva makes irregular linear mine on upper side of leaf throughout its whole stage. The mature larva makes an oval pupal chamber within the end of the mine. The figures of the male and female genitalia, mine, pupae in immature stages are provided. The subfamily Oecophyllembiinae Real et Balachowsky (Lepidoptera: Gracillariidae) is newly recorded from Korea for the first time.

There were no differences in the proportions of patients achieving normalisation of alanine aminotransferase (91.7%, 76.9%, 89.7%, respectively) and HBeAg seroconversion (11.11%, 15%, 9.52%, respectively) among all three groups. None of the patients had resistant mutations or increase in serum creatinine of >0.5 mg/dL from baseline. 64 (94.1%) patients on besifovir had lowering of serum L-carnitine (not tested in entecavir patients).

Blowfly and flesh fly have specific ecological characteristics that their larvae grow in decaying environments. To survive in this habitat against harmful pathogens and bacteria, the fly species produced antimicrobial peptides (AMPs), which are considered promising candidates for treating bacterial infections. In this study, to discover such valuable novel AMPs, three fly species were isolated from Pyeongchang-gun, Gangwon-do, South Korea. Through analysis of the mitochondrial cytochrome oxidase I gene, they were identified as Calliphora vicina, Lucilia illustris (Calliphoridae), and Sarcophaga kanoi (Sarcophagidae). Despite their medicinal and veterinary importance, the genetic information of these species has not been fully examined. Therefore, we generated transcriptome data sets of larval salivary glands and performed de novo transcriptome assembly. As a result, 29,531, 42,167, and 31,862 unigenes were assembled. These transcriptome data of blowfly and flesh fly isolated in Korea will allow the discovery of useful AMPs.
