Community structure and Biodiversity of Rice field spiders in Korea
Spiders play an important role in regulating insect pests in the agricultural ecosystem. The community structure and biodiversity of rice field spiders were surveyed in 5 areas (Anseong, Nonsan, Imsil, Namwon, and Gurye) from 20 May to 30 September, 2021. A total of 5,525 spiders collected were identified as 64 species of 17 families. Species richness and abundance were high in Lycosidae, Tetragnathidae and Linyphiidae. The similarity of rice field spider communities among regions was about 72% and was divided into three groups: the middle inland area, the southern mountainous area, and the southern inland area. Species diversity averaged as 2.55±0.06. On the seasonaliy of The boidiversity tended to increase toward the latter half of cultivation.
