Cecidomyiidae (Diptera) consists of six subfamilies, which are divided into three groups according to larval ecological habits (phytophagous, mycophagous, and zoophagous). The five basal subfamilies of Cecidomyiidae consist entirely of mycophagous species, with approximately 1500 species described worldwide and 29 previously known to occur in Korea. In this study, 37 named species (1 Lestremiinae, 29 Micromyinae, 4 Winnertziinae, and 3 Porricondylinae species) are newly reported from South Korea. We excluded Lestremia yasukunii Shinji from the list of Korean mycophagous cecidomyiids as it is a nomen nudum. Therefore, we herein officially recognize 65 species, 30 genera, and four subfamilies for the Korean mycophagous cecidomyiid fauna. We also provide diagnoses and photographs to aid species identification and discussion on the four years of gall midge taxonomic inventory in South Korea.

Mycophagous gall midges in the family Cecidomyiidae (Diptera) are poorly known in Korea, with only 14 recorded species. From our sampling throughout South Korea during 2015-2017, we present evidence of the Korean distribution of another 20 species as follows-Lestremiinae: Anarete angusta Mo & Xu, 2009; Micromyinae: Anodontoceras saigusai Yukawa, 1967, Campylomyza appendiculata Jaschhof, 2015, Campylomyza furva Edwards, 1938, Peromyia gotohi Jaschhof, 2001, Peromyia pumila Jaschhof, 2001, and Tekomyia populi Möhn, 1960; Winnertziinae: Leptosyna nervosa (Winnertz), 1852, Winnertzia nigripennis (Kieffer), 1894, and Winnertzia solidaginis Felt, 1907; Porricondylinae: Bryocrypta indubitata Mamaev, 1964, Camptomyia flavocinerea Panelius, 1965, Coccopsilis obscura (Mamaev), 1964, Coccopsilis paneliusi (Yukawa), 1971, Cryptoneurus muscicola (Kieffer), 1896, Dirhiza abludentis(Mamaev), 1998, Divellepidosis separata (Yukawa), 1971, Larimyia lavalis Fedotova & Sidorenko, 2007, Parvovirga latostylata Jaschhof, 2013, and Porricondyla nigripennis(Meigen), 1830.

경기도 8개 지역에서 2010년부터 2012년 동안 식균성인 노랑무당벌레의 발생기주를 조사한 결과, 흰가루병에 감염된 12종의 식물에서 관찰이 되었다. 특히 가장 밀도가 높았던 배과원에서 노랑무당벌레는 7월 상순부터 11월 상순까지 발견되었다. 식균성인 노랑무당벌레의 장내에서는 흰가루병 균사나 포자 외에 다른 먹이의 흔적이 발견되지 않았고, 알과 번데기를 제외한 전 발육단계에서 균을 섭식하는 특성을 볼 때 절대적 식균성 곤충으로 생각된다. $25^{\circ}C$에서 오이 흰가루병균을 섭식한 노랑무당벌레의 발육기간은 알, 유충, 번데기, 성충이 각각 3.9, 10.4, 4.1, 37.7일 이었고, 발육단계별 오이 흰가루병 섭식량은 45.6, 144.4, 372.2, 628.1, $473.7mm^2$로 4령, 성충, 3령, 2령, 1령 순으로 많았다. 본 연구를 통해 노랑무당벌레의 오이 흰가루병에 대한 섭식능력을 바탕으로 향후 유용 토착천적으로써 대량사육기술, 저독성 약제 선발 등 작물 흰가루병 종합방제기술(IPM)에 대한 연구가 필요하리라 사료된다.

Recently, Platypus koryoensis has been reported as a major pest of oak trees in Korea which can introduce the pathogenic fungus(Raffaelea sp.) by making galleries into the heartwood of the tree. As the beetle has developed its effective drilling mouthpart enough to make tunnels, we have analyzed the fine structural aspects of the mouthpart using the field emission scanning electron microscopy(FESEM) to reveal its mechano-dynamic characteristics. The mouthparts of this ambrosia beetle which consist of a labrum, a pair of mandibles, a pair of maxillae and the labium exhibit typical morphology of mycophagous coleopteran beetles and have those characteristics of chewing mouthparts that can excavate galleries in the hardwood. Both of maxillary and labial palpi have the functions of direct the food to the mouth and hold it while the mandibles chew the food. The distal ends of these palpi are flattened and have shovel-like setae. Females have larger maxillary palpi and a larger gular region than males in general.
