摘要
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 deals with the structure and dynamics of spider community- in paddy fields from Qiongshan County of Hainan Province. 49 spider species, which belong to 11 families, were collected in 1980 and 1981. Ummeliata insecticeps Boes. et Str. ,Hylyphantes graminicolum (Sundevall), Pirata subpiraticus (Bocs. et Str. ), Pardosa pseudoannulata (Boes. et Str. ), Pirata piraticus (Clerck) were the dominant species of spider community. The dominant species populations made up 70. 75% - 78. 84 % of the total spider, increased with the increase of the days after transplanting, and peaked on the 15th day after transplanting.
