  • Pardosa pseudolaevitarsis n. sp. and Hygrolycosa umidicola Tanaka, 1978 belonging to Lycosidae are described from Korea. To date, fourteen species in the genus Pardosa C. L. Koch, 1847 have been described from Korea. H. umidicola belongs to Hygrolycosa Dahl, 1908 was once described from Korea, but the previous description of this species could not provide adequate scientific evidence for adding H. umidicola to the Korean spider fauna. Pardosa pseudolaevitarsis n. sp. is similar to P. laevitarsis Tanaka & Suwa, 1986 in the shape of its epigyne and palp, but can be distinguished by the followings: epigynal atrium small; spermathecae extending to the end of atrium; shape, location and orientation of fertilization duct in epigyne and internal genitalia; blunt basal spur of median apophysis in palp; number, shape and arrangement cheliceral teeth on both margins. Both species were collected using pitfall traps on a ridge between rice fields and seem to prefer habitats with relatively high humidity.

  • To study the faunal compositiion of spiders as natural enemies of the insect pests and their seasonal fluctuation in paddy fields of Taegu, the survey was carried out 12 times between June and September. 1971. 1. The spiders collected in paddy field of Taegu during the survey period were 45 species of 30 genera of 10 families. 2. In percentage composition the spiders of the genus Pirata were most abundant. Among the other genera, the species of the genus Neoscona, Lycosa, and Marpisa were more abundant in the above-written order. 3. Pirata subpiraticus, Neoscona doenitzi, Lycosa sp., Pardosa T-insignita and Marpisa magister were the 5 major species of abundant spiders. 4. Comparing the spider-fauna of the paddy field of Korea with that of Japan, Taiwan and Thailand, 2 species of 2 genera of the family Gnaphosidae were found in Korea only The abundant and common species It·ere deeply different each other. 5. Pirata subpiraticus, Lycosa sp. and Pardosa T-insignita appeared abundantly between June and July while Neoscona doenitzi and Marpisa magister were few in these periods. But no Pirata subpiraticus, Lycosa sp. and Pardosa T-insignita appeared in August while Neoscona doenitzi and Marpisa magister were abundant in this period. Then, in September as between June and July, Pirata subpiraticus, Lycosa sp. and Pardosa Tinsignita were abundant while Neoscona doenitzi and Marpisa magister decreased.

  • This study was conducted to compare the community structure and biodiversity of arthropods between conventional and organic red pepper fields. A total of 36 species of 24 families belonging to 10 orders from collected 28,718 arthropods; 6,901 individuals from conventional field and 21,871 individuals from organic field. A number of species comprising arthropod community was same in both fields as 32 species. Species richness of Diptera was the highest in conventional field and that of Hymenoptera and Colembolla was the highest in organic field. Abundance of Frankliniella intonsa was the highest regardless of farming method. Helicoverpa assulta was dominant in conventional field, and Homidia mediaseta, Diptera sp. 4 and Pardosa astrigera were dominant in organic field. Diversity of community on the ground was higher in organic field and statistically different. Similarity of arthropod community showed difference with 34.07% on the ground and 26.95% in the plant above ground. In the ecologically functional guild: species richness of general, pest and parasitoid of natural enemy groups in the plant above ground were statistically different and pest and parasitoid groups were higher in organic field, abundance of predator group of natural enemy on the ground was 2 times higher in organic field and statistically different and diversity of general and parasitoid groups in the plant above ground were statistically different. In the relative occupancy rate, pest group was the highest in conventional field and decomposer group was the highest in organic field. The results of present study is considered to provide useful information of arthropod community for developing efficient insect pest management in organic farming.
