报道海南省琼山县稻田蜘蛛群落的物种组成及其优势种群的动态变化。已鉴定的稻田蜘蛛种类有49种.分属11个科。食虫沟瘤蛛Ummeliata insecticeps Boes.et Str.、草间钻头蛛Hylyphantes gramini-colum(Sundevall)、拟水狼蛛Pirata subpiraticus(Boes.et Str.)、拟环纹豹蛛Pardosa pseudoannulata(Boes.et Str.)和真水狼蛛Pirata piraticus(Clerck)是群落的优势种,其种群数量占稻田蜘蛛总量的70.75％～78.84％。各优势种种群数量随水稻移植天数的增加而增加,至79 d(抽穗期)时达到最高峰。
This paper reports the species composition of spider communities in paddy fields and the dynamic changes of dominant populations in Qiongshan County, Hainan Province. Has identified the type of rice spiders 49 species belonging to 11 families. Ummeliata insecticeps Boes.et Str., Hylyphantes gramini-colum (Sundevall), Pirata subpiraticus (Boes.et Str.), Pardosa pseudoannulata (Boes.et Str.) And Pirata piraticus (Clerck) are the dominant species in the community, accounting for 70.75% -78.84% of the total population of spider in paddy field. The population of each dominant species increased with the days of rice transplanting, reaching its peak at 79 days (heading date).
