In this study, in order to examine the change of soil animals by vegetation restoration types, experimental sites with biotope restoration method, forest topsoil paving method, small diameter trees planting method and multi-layer community planting method were applied and the control site was selected. The naturalness of soil animals was analysed by studying the change of soil animals. It was confirmed that the control site has a high level of the naturalness of soil animals as it includes a mixture of fauna sensitive and insensitive to environment distributed widely over the site. The experimental site with biotope restoration method showed a similar level of the naturalness of soil animals as the control site. Furthermore, the naturalness of soil animals in the experimental sites with small diameter trees planting method and multi-layer community planting method also showed a progressive restoration although the level of the naturalness of soil animals is lower than the experimental site with the biotope restoration method. Therefore, it is confirmed that the experimental site with biotope restoration method shows a faster recovery of soil animal than other sites. This is because this method uses the portion of topsoil and subsoil that were dug from the intact forest during transplantation.

This study includes the taxanomy, description and a key to species of mites in the family Bdellidae from Korea. Specimens were collected at 60 localities in Korea from January, 1994 to June, 1997. As a result of this study, the following 7 species were identified : Bdella longicornis ( Linnaeus, 1758), Bdella muscorum Ewing, 1909, Cyta latirostris (Hermann, 1804), Biscirus thori Womersley, 1933, Spinibdella tenurostris (Ewing, 1914). Six species excluding Bdella muscorum of them are newly recorded from Korea.

Astigmatid mites collected from forest and pasture soil in Korea during the period of June, 1997 to July, 1998 were examined, and seven species were identified as follows. 1. Tyrophagus putrescentiae (Schrank, 1781) 2. T. longior (Grevais, 1844) 3. T. similis Volgin, 1949 4. Rhizoglyphus robini Claparede, 1869 5. Suidasia nesbitti Hughes, 1948 6. Histiostoma feronarium (Dufour, 1839) 7. H. sapromyzorum (Dufour, 1839) of them T. longior, T. similis, H. feronarium and H. sapromyzorum are newly added to Korean fauna.

Effects of temperature, pH, and salt concentration on the preservation of the infective juvenile entolopathogenic nematodes, Steinernema carpocapsae, were analyzed. The effects of acclimation to sublethal low temperature and glycerol concentrations on rapid cold hardening of the nematodes were also evaluated to set up the conditions for their cryopreservation. All tested environmental factors could change the storage effectiveness of the nematodes. These analyses indicated that the optinal storage condition for the nematodes consisted of $15^{\circ}C$, pH 8.5, and 0.5-1.0% salt concentration. The nematodes showed a rapid could hardening in response to $5^{\circ}C$ for 2h. Glycerol induced the nematodes to increase the cold hardiness. Its high concentration over 10%, however, gave a harmful effect on the nematode survival.

According to the related references, up to now the systematic studies on the ants from Mt. Moak have not been professionally surveyed yet. On order to classify the the ants from Mt. Moak, authors had collected the ants in this area from Octorber, 1993 to June, 1995. Examining all the collections, 44 species of 23 genera of 17 tribes under 3 subfamilies were identified.

This study includes the taxanomy, description and a key to species of mites in the genus Asca from Korea. Specimens were collected from December 1993 to May 1996. As a result of this study, the following three species were identified. 1. Asca (Asca) aphidioides (Linne, 1758) 2. Asca (Asca) sculptrata Aoki, 1968 3. Asca (Asca) garmani Hurlbutt, 1963 These three species have not been described from Korea.
