| 摘 要： | 对四会市大沙镇稻田主要节肢类捕食性天敌群落的结构和动态进行了研究。结果表明,节肢类捕食性天敌包括捕食性昆虫和蜘蛛两大类,共15科36种;群落的垂直结构可分为两个主要层。早稻群落结构随着时间的变化,优势种和亚优势种也在不断变化之中,晚稻群落中的优势种地位虽无变化,但种群数量却在不断波动。

| Abstract: | From September, 1992 to November, 1993, We investigated the main arthropod preda-tor community in rice field in Dasha Town of Sihui County, Guangdong Province. This paper dea-ls with the structure and dynamics of the community.The community was made up of 36 species which belong to 15 Families. The vertical struc-ture of community consists of two main layers: leaf layer and stem layer. Tetragnathidae, Aranei-dae, Oxyopidae, Clubionidae and Verania discolor occupy the leaf layer; Ummeliata insecticeps, Pirata spp. , Pardosa psudoannulata, Salticidae, Coleosama octomaculata, Hypsosinga pygmaea , Staphylinidae and Carabidae occupy the stem layer. The dominant species and subdominant species of communi-ty in early rice field changed continually. In late rice field, the dominant species unchanged, but its population changed continually and severely. |
