摘 要：
【目的】了解套种圆叶决明杧果园节肢动物群落的特征,明确套种圆叶决明是否有利于控制杧果园主要害虫,【方法】于2008年4—9月对福建省惠安县套种圆叶决明的杧果园和无套种的清耕园节肢动物群落进行系统调查。【结果】在套种园共采集到2纲、12目、52科、73种节肢动物;在清耕园共采集到2纲、12目、44科、57种节肢动物。套种杧果园优势种为中国小黑蚁Monomorium chinensis和红蚂蚁Tetramorium guineense,2者均为捕食性天敌昆虫;清耕园的主要优势种为茶黄蓟马Scirtothrips dorsalis和棉古毒蛾Orgyia postica,这2种昆虫均为危害杧果的害虫。套种圆叶决明显著提高了杧果树节肢动物总群落、天敌亚群落的物种丰富度和丰盛度以及中性昆虫亚群落丰盛度,但对其他群落特征指数间无显著影响。【结论】杧果园套种圆叶决明增加了天敌昆虫的种类和数量及中性昆虫的数量,对调节杧果园节肢动物群落结构具有一定的作用,利于杧果园害虫的综合治理。

摘 要：
【Objective】The objective of the study was to investigate the effect of interplanting Chamaecrista rotundifolia on arthropod community in mango orchard,and to definite whether interplanting C. rotundifolia is benefit to control pests or not in mango orchard.【Method】The composition and diversity of arthropodcommunities in the mango orchards with or without interplanting C. rotundifolia were investigated in Hui'an country,Fujian Province,China from April to September in 2008.【Result】The results showed that 73 arthropod species belonging to 12 orders,52 families in the interplanting orchards and 57 arthropod spe-cies belonging to 12 orders,44 families of Insecta and Arachnoidea in the non-interplant orchard were col-lected. The dominant species in interplanting orchard were Monomorium chinensis and Tetramoriumguineense which were predatory natural enemies,but the main dominant pests in non-interplanting or-chard were Scirtothrips dorsalis and Orgyia postica which harm mango. The species richness and individualof total community and natural enemies were greater in the interplanting orchard than in the non-interplantorchard,but interplanting showed no significant effect on the other subcommunities.【Conclusion】The re-sults suggested that interplanting C. rotundifolia in mango orchard could increase the species and quantityof enemy insect and the quantity of neutral insect,and have a certain degree of benefit to control the arthro-pod community structure,which are helpful to integrated pest management in mango orchard.
