摘要
1999～2000年在广东、海南、福建3省的3个稻作亚区选取27个样地,调查早、晚稻田蜘蛛群落,分析各种蜘蛛的优势度。结果表明:食虫沟瘤蛛和拟水狼蛛是闽粤桂台平原丘陵双季稻亚区(Ⅰ_1)早稻田的优势种,四斑锯螯蛛、拟环纹豹蛛和一些地区的拟水狼蛛是晚稻田的优势种。江南丘陵平原双季稻亚区(Ⅱ_3)的食虫沟瘤蛛和拟水狼蛛是早、晚稻田的优势种,四斑锯螯蛛和锥腹肖蛸是部分地区的优势种。琼雷台地平原双季稻多熟亚区(Ⅰ_3)的拟环纹豹蛛、四斑锯螯蛛是晚稻田的优势种。
In 1999 and 2000,spiders were investigated in 27 sampling rice fields of Guangdong, Fujian and Hainan Provinces. In the Ⅰ1 rice sub - region,dominant species were Ummeliata insecticeps and Pirata subpiraticus in the first rice season,and Dyschiriognatha quadrimaculata and Pardosa pseudoannulata in the second rice season;in some sampling sites, Pirata subpiraticus was the dominant species in the second rice season. In the Ⅱ3 rice sub - region,Ummeliata insecticeps and Pirata subpiraticus were the dominant species in both seasons; in some sampling fields, Dyschiriognatha quadrimaculata and Te-tragnatha mazillosa were the dominant species in the second rice season. In the second rice season in Ⅰ3 rice sub -region,dominant species were Pirata subpiraticus and Dyschiriognatha quadrimaculata.
