The leafhopper family Cicadellidae (Hemiptera: Auchenorrhyncha) is plant feeders, with mouthparts adapted for sucking. Almost of the them cause injuries of destruction to plants, including fruit trees and grain crops, and can be vectors of plant diseases. Therefor, Cicadellidae is one of the most important pests in the world. However, their identifications are very difficult because of small size and morphological similarities, and their exact biological information such as host plants, life cycle and distribution are not clear for most species. So, we provide and integrated biological database that present accurate diagnostic methods and ecological infromation.

중기문응애목에 속하는 기생응애과(Parasitidae) 응애는 몸집이 크고 활동력이 왕성한 중요 토양 포식자이다. 토양응애 다양성 연구 중 국내 미기록종 기생응애과를 발견하여 보고하는 바이다. 이 논문에서는 온판기생응애속(genus Cycetogamasus) 2종, 한국온판기생응애(Cycetogamasus coreanus), 주름온판기생응애(C. corculatus), 두판기생응애속(genus Neogamasus) 5종, 두판기생응애(Neogamasus eogenualis), 티코미로비두판기 생응애(N. tikhomirovi), 이쁜두판기생응애(N. laciniatus), 경기두판기생응애(Neogamasus kengicus), 마훈카두판기생응애(Neogamasus mahunkai) 를 한국의 미기록종으로 보고한다.

Pine wood nematode (Bursaphelenchus xylophilus), the pathogen of pine wilt disease (PWD), is transmitted to new host trees through Monochamus spp., vector insects. In Korea, aerial application has been allowed conventionally to eliminate the vectors in their flying season. In this study, thiacloprid was applied to four-year-old Pinus densiflora, which were fed to adult M. alternatus emerged from PWD infected logs for 72 h in the condition of 1 DAT (Days after treatment of thiacloprid) and 15 DAT, respectively. We confirmed the presence of nematodes in each beetle applied to experiment by Baermann funnel method and PCR with species-specific ITS primers. After 72 h of 1 DAT and 15 DAT, thiacloprid residues in pine trees were 0.59-16.32 and 0.043-0.131 mg/kg and the mortalities of the beetle were 100 and 99.2%, respectively. Detection rate of B. xylophilus was 51.3%. The incidence rate of PWD in 1 DAT and 15 DAT showed no mortality and 5.55% compared with 55.5% of control, respectively.

The leafhopper subfamily, Typhlocybinae (Hemiptera: Auchenorrhyncha: Cicadellidae), caused direct damage by sap-sucking or indirect damage by transmission of viruses or diseases to the host plants, so Typhlocybinae is one of the most important insect pests in agriculture, urban ecology, forest, etc. in the world. However, their identifications are very difficult due to small size and morphological similarities, and their exact biological information such as host plants and life cycle are not reported yet for most species. So, we construct an integrated biological database that presents accurate diagnostic methods (illustrated key characters, DNA barcoding data), patterns and seasons of occurrences, and some ecological photographs such as dorsal habitus of specimens and plant damages

The subfamily Iassinae Walker belongs to the family Cicadellidae (Hemiptera: Auchenorrhyncha). A total of 124 genera with 1,999 species have been described in the world. To date, two genera, Batracomorphus Lewis and Iassus Fabricius, and 5 species of the subfamily have been recorded in Korea. In this talk, one new species and one new record of the genus Batracomorphus and one new species and two new records of the genus Iassus from Korea are presented. And we also provide biological information such as host plants and distributional records of the Korean Iassine species.
