摘　　要：【目的】明确南宁市柑橘木虱(Diaphorina citri)自然天敌种类以及柑橘木虱数量与天敌数量的相关性,为利用天敌防控柑橘木虱提供科学依据。【方法】2020年8月-2021年7月在广西大学农场多功能标本园内未喷施过化学农药的九里香绿篱和广西创新驱动专项基地内砂糖橘果树上采用随机取样法调查柑橘木虱自然天敌种类,统计捕食性天敌的数量及寄生性天敌的寄生率,每15 d调查1次。【结果】调查发现南宁市柑橘木虱的自然天敌共有15种,其中昆虫纲天敌9种,包括六斑月瓢虫(Menochilus sexmaculata)、龟纹瓢虫(Propylea japonica)、双带盘瓢虫(Lemnia bip-lagiata)、粗网巧瓢虫(Oenopia chinensis)、异色瓢虫(Harmonia axyridis)、中华草蛉(Chrysoperla sinica)、亮腹釉小蜂(Tamarixia radiate)、阿里食虱跳小蜂(Diaphorencyrtus aligarhensis)及豹纹花翅蚜小蜂(Marietta picta);蛛形纲天敌6种,条纹金蝉蛛(Phintella vittata)、角红蟹蛛(Thomisus labefactus)、锈宽胸蝇虎(Rhene rubigera)、多色金蝉蛛(P.versicolor)、斜纹猫蛛(Oxyopes sertatus)及园果大赤螨(Anystis baccarum)。发现亮腹釉小蜂的1种寄生蜂黄食虱跳小蜂(Psyllaphycus diaphorinae)。【结论】南宁市柑橘木虱自然天敌共15种,主要捕食性天敌为六斑月瓢虫,主要寄生性天敌为亮腹釉小蜂。当地柑橘木虱自然天敌资源丰富,在田间应加强保护和合理利用,提高天敌对柑橘木虱的自然控制能力。【Objective】To make clear the natural enemy species of Diaphorina citri in Nanning,and to investigate the correlation between quantity of D.citri and the number of natural enemy,so as to provide a basis for the control of D.citri by natural enemies.【Method】From August 2020 to July 2021,natural enemy species of D.citri were inves-tigated by random sampling method and the number of predatory natural enemies and parasitism ratio of parasitic natu-ral enemies were counted once every 15 days at the Murraya paniculata var.exotica hedgerow without chemical pesti-cide spraying in the Multi-functional Garden and citrus trees(Citrus reticulate cv.Shatangju)in Guangxi Innovation driven Special Base of the farm in Guangxi University.【Result】A total of 15 natural enemies of D.citri were found in Nanning,in which 9 species of natural enemies belonged to Insecta:Menochilus sexmaculata,Propylea japonica,Lemnia biplagiata,Oenopia chinensis,Harmonia axyridis,Chrysoperla sinica,Tamarixia radiate,Diaphorencyrtus aligarhensis and Marietta picta.And 6 species of natural enemies belonged to Arachnid:Phintella vittata,Thomisus labefactus,Rhene rubigera,P.versicolor,Oxyopes sertatus and Anystis baccarum.A parasitic wasp of T.radiate,Psyllaphycus diaphorinae was found.【Conclusion】There are 15 natural enemies of D.citri in Nanning,and the domi-nant predatory natural enemy is M.sexmaculata and the dominant parasitic natural enemy is T.radiate.
