This study includes the taxonomy and occurrence of ticks and mites from Jinju, Kyogsangnamdo province, Korea. Materials examined were attraccted to carrions of chicken and cattle flesh from September 2002 to December 2003. As a result, the following seven species were identified. Suborder Ixodida Family Ixodidae 1. Haemaphysalis longicorttis Neumann, 1901 Suborder Mesostigmata Family Machrochelidae 2. Macrocheles muscaedomesticae (Scopoli, 1772) 3. Holostaspella ornata (Berlese, 1904) Family Ascidae 4. Protogamasellus micus (Athias-Henriot, 1961) 5. Lasioseius sugawarai Ehara, 1964 6. Proctolaelaps sp. Suboder Prostigamta Family Erythraeidae 7. Abrolophus sp. Of these, M. muscaedomesticae and Protogamasellus micus are dominant species. Holostaspella ornate(Berlese, 1904) and Protogamasellus mica(Athias-Henriot, 1961) are new to Korean fauna.

Two years-study with litter bag (mesh size : 0.4 mm, 1.7 m) was carried out from Nov., 1996 to Sept., 1998 to investigate the soil microarthropod community in the process of needle leaf secomposition of Korean pine (Pinus koraiensis) forest in Namsan and Kwangreung, where were supposed to be under different environmental selective pressures. Soil arthropoda collected from litter bags were sorted into suborders or higher taxa. Acari and Collembola were dominant groups, which were 61-68% and 27-35% of total soil arthropod in their numbers, respectively. Among Acari, Oribatida was major group, and Gamasida and Actinedida were minor groups. Abundance of Acari was a little higher in Kwangreng than in Namsan. But there was not significant difference between the arthropod community structure of Namsan and Kwangreng forest. And the different mesh sizes (0.4 mm and 1.7 mm) of litter bags could not make significantly different community structures in the litter bags. One taxon showed different pattern of population dynalics from another. But Oribatida, Gamasida and Collembola showed peak density in July, 1997. All taxa showed lower population densities in cold season i.e. Nov., Jan. and March. There was not significant difference in decomposition rate between Namsan and Kwangreng forest, and between mesh sizes of litter bags. % residual mass of needle leaf was about 40% at 22 months after litter fall.
