摘　　要：长沙市东方红农场东塘分场共有稻田蜘蛛11科29属43种,其优势科为狼蛛科、皿蛛科、球蛛科和肖蛸科;优势种为拟水狼蛛、食虫沟瘤蛛、八斑鞘腹蛛和锥腹肖蛸.在水稻发育各期,综合防治田蜘蛛群落的丰富度(S)和个体总数(n)均大于化学防治田,晚稻田蜘蛛群落的丰富度(S)均大于相应防治的早稻田,同时发现稻田蜘蛛群落物种丰富度高的稻田,害虫的丰富度较低,反之则高.The result of the research on community structure makes it clear that there are total 43 species 29 genus 11 families of spider in the rice field in Dong Fanghong Farm,Changsha city.The dominant families are Lycosidae,Linyphiidae,Theridiidae and Terahnathidae;the dominant species are Pirata subpiraticus,Ummeliata insecticeps,Coleosoma simon and Tetragnatha maxillosa.The species richness and total individuals of spider community under IPM are higher than those in chemical controlling fields in every development stage of rice, the species richness and total individuals of spider community in the late rice field are also higher than those in the early rice field of the same controlling.The species richness of spider community is higher,while the species richness of pests community is low in the rice field.
