  • This study investigated the impact of the fire disturbance and the pattern of recovery of soil dwelling oribatid mite communities with respect to the resilience from the fire disturbance. Oribatid mites are important decomposer animals of plant debris in soil with the feeding habits of saprophagy and mycophagy. Massive wild fire reduced soil oribatid mite abundance and diversity. The impact varied relative to the intensity of the disturbance. The proportion of the species common to the non-disturbed natural site increased as the time after the disturbance elapsed, which implying some degree of naturalness occurring in reorganization phase of the oribatid mite community. From the sites with different degree of fire impact, we found higher diversity in intermediately disturbed sites than in severely disturbed or non-disturbed site, supporting the intermediate disturbance hypothesis. Also this study showed that with differential degree of disturbance plots, resilience pattern after the disturbance can be explored even with shorter period research relative to the ecological succession of community.

  • Four mite species (Acari: Scutacaridae: Scutacarus acarorum (Goeze, 1780), Chaetodactylidae: Sennertia alfkeni (Oudemans, 1900); Ascidae: Proctolaelaps longanalis (Westerboer, 1963), Laelapidae: Hypoaspis (Pneumolaelaps) marginepilosa (Sellnick, 1938) are found on the body of bees deposited in the Hungarian Natural History Museum, Budapest. The host bee species were collect in Democratic People's Republic of Korea; the found four species are collected at first time in Democratic People's Republic of Korea.

  • This research is aimed at evaluating the potential abilities of the natural acaricide of F. suspense oil against Tyrophagus putrescentiae and Dermatophagoides spp. Based on the $LD_{50}$ values, in contact bioassay, F. suspense oil (8.19, 3.28, and $4.35{\mu}g/cm^2$) showed acaricidal effects against T. putrescentiae, D. farinae, and D. pteronyssinus, respectively. Fumigant toxicities of F. suspense oil showed similar patterns as those observed with contact toxicities. GC/MS analysis showed the major components of F. suspense oil to be ${\beta}$-pinene (45.88%), myrtenol (13.86%), (+)-${\alpha}$-pinene (13.09%), (-)-trans-pinocarveol (7.34%), sabinene (6.64%) and pinocarvone (4.13%). These findings indicate that F. suspense oil has potential as a natural acaricide.

  • Mites of the genus Antennoseius of family Ascidae are free-living soil predator mostly observed on the open grass field. In Korea, only two species, Antennoseius imbricatus Ishikawa, 1969 and A. japonicus Ishikawa, 1979 were reported in 1990s. Recent series of soil acarine biodiversity survey in Gyeongbuk province during 2009-2015. We recovered a new record of Antennoseius avius (Karg, 1976) to Korean inventory from riparian grassland. Detailed description of the species as well as the identification key to the genus and species were provided.

  • Assocations of wingless mites with winged arthropods highlight important life history strategies and ecological interactions. Here we report a mesostigmatan mite species association with an earth-boring dung beetle. Mite spciemens were collected from the soil of organic apple orchards in the Province of Gyeongsangbuk-do, Republic of Korea, and cattle dung was collected from grassland in Mongolia. The species was identified as Alliphis necrophilus Christie, 1983 (Acari: Eviphididae). This is the first report of any species in the genus Alliphis in Korea. Some descriptive details and ecological remarks are also provided.

  • Four feather mite species, Grallobia fulicae (Trouessart, 1885), Grallobia gallinulae Gaud, 1968, Grallolichus proctogamus (Trouessart, 1885) and Megniniella gallinulae (Buchholz, 1869), previously unrecorded in South Korea are reported. Specimens of Grallobia fulicae and Grallolichus proctogamus were collected from the eurasian coot, Fulica atra in Cheongju-si. Grallobia gallinulae and M. gallinulae were found on the common moorhen, Gallinula chloropus in Yesan-gun. The genera Grallobia Hull, 1934, Grallolichus Gaud, 1960 and Megniniella Gaud, 1958 are new records for South Korea. Here, we provide illustrations and morphological descriptions of these four feather mite species as well as the partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) as DNA barcodes.

  • Cockroach antigen have been known as a cause of allergic disease. German ockroach(Blattella germanica L.) was chosen because it has the highest distribution range and poulation density. To identify the common and specific antigens of adult and larval stage of german cockroach, we made monoclonal antibodies which were confirmen by SDS-PAGE and EITB. Anti-B. germanica antibody producing hybridomas were 24 among the total 960wells. Only 4 hybridomas did not have cross reaction to other species of cockroach and hluse dust mites(Dermatophagodies farinae and D. pteronyssius). SDS-PAGE revealed about 20 bands from 90Kd to 15Kd to 15Kd. ETB showed specific antigens a6 60, 72 and 82Kd which were experimented by the culture supernatant of 4 selected hybridomas. Especially 60Kd coincided with a band of immunized mouse sera.

  • 전보에서 외국산에 의해 기록된 한반도산 날개응애류 26종과 필자가 채집한 미기록종 29종 도합 65종의 목록을 발표한 바 있다. 그 후의 채집품을 조사결과 다수의 미기록종이 발견되었기에 전보를 증보하여 발표한다. 이로서 한반도산 날개응애류는 29상과, 59과, 99속, 158종이 되었다. 이밖에 미정리분중에도 약 50중의 미기록종이 포함되어 있으므로 한국산 날개응애류는 200여종이 되는 셈이지만 한국에 실재하고 있는 종수는 그 $2\~3$배가 될 것으로 추측된다. 또한 분포를 논할 단계는 아니지만 일본과의 공통종은 69종, 구주와의 공통종은 51종, 3자공통종은 55종이 되어 한반도 고유종은 34종이 된다. 그러나 우리나라와 인접해 있는 중국대륙의 날개응애상이 밝혀지면 고유종은 줄어들고 중국과의 공통종이 많아질 것이다.
