Abstract
The fauna of spider species inhabited near paddy fields have been investigated in Chinju and Namhae areas. The spiders collected near the paddy fields in Chinju and Namhae areas were 34 species of 31 genera belonging to 10 families: 34 species on paddy levees; 16 species on barley fields; 17 species on fallow fields; and 18 species on paddy fields. The species diversity was the highest on paddy levee. The dominant species collected from each habitat near the paddy fields were Pardosa astrigera on the paddy levees and barley fields, Pirata subpiraticus on the fallow field, and Pachygnatha clercki on the paddy fields. The spiders inhabited near rice fields can be classified into nine groups based on the ecological and taxonomical characteristics: 1. Pirata spp. 2. Pachygnatha clercki 3. Teridiidae, Erigonidae, Linypidae 4. Tetragnatha spp. 5. Dolomedes surfureus 6. Pardosa spp. 7. Salticidae 8. Thomisidae 9. Clubionidae Among the nine spider groups, the spiders belong to the group 1-5 prefered wet ground or paddy to dry ground, in contrast to the group 6-9 which prefered to live on dry land. The difference of the habitat preference indicated that the former five groups do the important roll as pest predators in paddy, while the latter four group mainly suppress the overwintering pest populations on paddy levees.
