This study includes the taxonomy, description, and a key to species of mites in the Family Zerconidae(Acari, Mesostigmata) from the Korean Peninsula. Materials examined and information gathered were based on 1,020 specimens which has been collected nation-wide from April, 1994 to May, 2000. As a result of this study, the following 8 species were identified : Exhinozercon orientalis Blazak, 1975, Eurozercon pacificus Halaskova, 1979, Kaikiozercon mamillosus Halaksova, 1979, Kaikiozercon peregrinus Halaskova, 1979, Koreozercon bacatus Halaskova, 1979, Mesozercon coeranus Blaszak, 1975, Mesozercon plumatus (Aoki, 1966), Zercon szeptyckii Blaszak, 1976. Predominant species was Zercon szeptyckii which has been collected more then 600 specimens at 25 localities in the Korea Peninsula. Seven species except Mesozercon plumatus(Aoki, 1966) had been recorded from North Korea but newly recorded from the southern part of Korean Penunsula.

This study is based on specimens which had been collected from Chollabuk-do and Cuungcheongbuk-do provinces in November 1994 through February 2000. As a result, the following 2 species are described as new to science: Echinozercom fortunatus sp. n. and Eurozercon aserrisetarius sp. n.

This study was based on 8 species as follows. Specimens had been collected from 8 localities in Korea from April to September, 2002: Echinozercon orientalis Blaszak, 1975 Eurozercon pacificus Halaskova, 1979 Kaikiozercon mamillosus Halaskova, 1979 Kaikiozercon peregrinus Halaskova, 1979 Koreozercon bacatus Halaskova, 1979 Mesozercon coreanus Blaszak, 1975 Mesozercon plumatus (Aoki, 1966) Zercon szeptyckii Blaszak, 1976 The size of idiosoma and the length of setae on proscrotum and postscrotum were compared with the data of North Korean specimens . Two species (E. orientalis, Z. szeptyckii) are similar, three species (E. orientalis, K. bacatus, M. coreanus) are small but not much different and the rest three species (K. mamillosus, K. peregrinus, M. plumatus) are small and much different in measurements of setae from those of the North Korean specimens.

Mites were collected from organic cultivations of greenhouse cucumbers and identified as Tyrophagus neiswanderi (Acari: caridae). T. neiswanderi (length, $490.1{\mu}m;$ width, $288.1{\mu}m$) is a very small, milky-white, and egg-shaped mite, and it mainly causes damage to the leaves, flowers, and fruits of cucumber plants. In the early growing season of cucumbers, the shoots of seedlings became pale and yellow because of T. neiswanderi, and eventually shrinkage or bud-failing was observed in the plants. In the middle of the growing season, T. neiswanderi caused white spots on the leaves and flowers of the plants, and the spots gradually became holes. T. neiswanderi also caused severe damage to young fruits by feeding on the rinds of the fruits, inducing malformations and lowering the economic value.
