To clarify the spider fauna of Geojedo Island, a field survery was conducted in August, 1997. As a result, 92 species belonging to 56 genera of 20 families were collected. Identified spider are composed of 6.60% Palaearctic, 7.70% Holarctic, 2.20% Oriental, 3.30% cosmopolitan species. Spiders of Theridiidae, Araneidae and Salticidae were dominant, 82(90.1%) and 75 species(82.4%) of spiders were found in common with Japan, China, respectively. Faunal similarities between Geojedo island and Deogjeong Archipelago, Chejudo Island, Ulleungdo Island, Chindo Island, Paiklyeongdo Island and Kogeumdo Island are discussed.

The natural enemies of Black pine bast scale (Matsucoccus thunbergianae) were surveyed total 24species, 7families, 4orders in predatory insects and 29species 1 lfamilies in a predatory spiders. In insect, Coleoptera IOspecies, Hymenoptera 7species, Hemiptera 6species, Dermaptera 1 species were investigated. Among them high frequency and population density were Chilocorus rubidus, Harmonia axyridis of Coleoptera, Brachyponera chinensis, Vesp~ilac rabro flavofasciata of Hymonoptea, Sphedanolestes impressicollis, Velinos nodipes of Hemiptera. Anatis halonis, Anisostictu kobensis of Coleoptea and Cydnocoris russatus of Hemiptea were newly investigated. In spiders, Araneidae gspecies, Thomisidae Sspecies, Lycosidae 3species, Salticidae 3species, Pisauridae 2species, Theridiidae 2species, Tetragnathidae 2species, Oxyopidae lspecies, Gnaphosidae I species, Clubionidae I species, Atypidae 1 species were investigated. Which high frequency and concentrating predatory species were Argiope bruennichii, Araneus ventricosus, Neoscona melloteei, Neoscona scylloides of Araneidae, Lycosa suzurii, Pirata sp. of Lycosidae, Marpissu elongata of Salticidae, Dolomedes stellatus of Pisauridae, Oxyopes sertatus of Oxyopidae. Neosconu scylloides, Cvclosa laticauda of Araneidae, Synema globosum, Xysticus ephippiatus, Misumenops tricu~pidat~o~f .T~h, omisidae, Marpissa elongata, Dendryphantes atratus of Salitidae, Perenethis .fascigera of Pisauridae, Tetragnatha pinicola of Tetragnathidae, Zelotes asiaticus of Gnaphosidae.

Spider fauna of Mt. Gajisan in Miryang, Gyeongsangnam-do was investigated from June to October. Collecting spiders was made by sweeping, beating, sieving and pitfall trapping. Total 66 species of 59 genera belonging to 20 families were identified from 317 collected spiders. Species richness was high in Salticidae (12 species, 20.0%), Theridiidae (8 species, 12.1%), Linyphiidae (5 species, 7.6%), Araneidae, Corinnidae, Gnaphosiade and Thomisidae (4 species, 6.1% repectively), Tetragnathidae, Amaurobiidae and Philodromidae (3 species, 4.5% repectively). Zoogeographical species were 1 Pantropical species (1.5%), 4 Palearctic species (6.1%) and 3 Korean endemic species (4.5%). This result will be a valuable monitoring data in comparative study of mountain spiders.

Fine structural characteristics of the heart tube and its cardiac muscle cells in spider, Araneus ventricosus are investigated by both of scanning and transmission electron microscopes. The heart tube of the spider is extended mid-dorsally along the anterior part of the abdomen, and is consisted of the thin outer layer of connective tissue (epicardium) and the thick muscle layer (myocardium). The myocardium in the spider has a typical fanlike spiral structure toward anterior part put across between the muscle fibers. Therefore, it did not give rise to the intima, and muscle cells are in direct contact to the hemolymph. The heart tube appeared to be three pairs of ostia and numerous hemocytes accumulated at the inner surface of the myocardial layer. Among several kinds of the hemocytes, the oenocytoids are the most predominant hemocytes accumulated along the myocardial folds which stretched toward heart lumen. The heart muscle cells are cross striated, branched, and multinucleated. They contain a lot of mitochondria, which provide for the continuous energy demands of the heart. Thread-like ganglion on the dorsal side of the heart tube gives off axons that innervate the heart muscle cells.

A faunistic study on the spiders (Arachnida: Araneae) from Mt. Jumbong Kangwon-do was carried out from 1996 to 1999. During the survey period, 144 species of 88 genera belonging to 27 families including 5 undetermined species were identified from 900 collecting individuals. The dominant families were Linyphiidae 21 species; 14.6% of total species), Araneidae (20 species, 13.9%), Theridiidae (16 species, 11.1%), and Salticidae 12 species, 8.3%). The composition of the species of web builders was richer than that of hunters. As for species commonness with adjacent countries, the numbers of common species between Mt. Jumbong and Japan, Mt. Jumbong and China, and Mt. Jumbong and Russia were 15 species (80.4%), 98 species (68.5%), and 48 species (33.6%), respectively. The number of common species among these four regions were 39 species (27.3%). So, the spider species composition in Mt. Jumbong seemed being much similar to those in neighbor countries. An outline of biogeographical distribution of spiders can be summarized as 1 Cosmopolitan species (0.7%), 16 Palearctic species (11.2%), 7 Holarctic species (4.9%), 25 Korean endemic species (17.4%) and no Oriental species. In the spider fauna at Mt. Jumbong, therefore, there are high level of occurrence of Korean endemic species with northern spiders as Palearctic and Holarctic species. The level and direction of man-made development may have negative effect on regional biota.
