香蕉园害虫和捕食性节肢动物群落结构及动态研究

摘要

A survey of arthropod species including pests,predactious arthropod and neutral insects was did and 18 orders,74 families,181 species were found in the banana field in Nanning.Pest and spiders feature predominant subcommunities in banana arthropods.Stephanitis typica,Bagworm-(Psychidae),Paratrechina bourbonica,Uloborus guangxiensis,Hylyphantes graminicola,Pardosa pusiola are the main components of the community in the banana plantation.The paper analysed the temporal and spatial structures of four subcommunities and its numeral dynamics as well as its relationships with the ecological environment in the banana fields.%报道了南宁市香蕉园害虫、捕食性节肢动物和中性昆虫亚群落结构，由18目74科181种组成。害虫和蜘蛛是构成香蕉园节肢动物群落组成及功能作用的主要群落。香蕉冠网蝽(Stephanitis typica)、袋蛾类(Psychidae)、广西抚蛛(Uloborus guangxiensis)、草间钻头蛛(Hylyphantes graminicola)、幼豹蛛(Pardosa pusiola)、布立毛蚁(Paratrechina bourbonica)是群落的主体。且分析了香蕉园4个亚群落的时、空结构，数量波动及其与蕉园生态环境的相互关系。
