  • 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.

  • 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.
