摘　　要：【目的】为了合理保护和利用天敌及科学地选取抽样方法,2015年和2016年开展了合肥地区白毫早茶园八点广翅蜡蝉Ricania speculum Walker、茶尺蠖Ectropis obliqua Warren、花蓟马Frankliniella intonsa Trybon和茶蚜Toxoptera aurantii Boyer与其天敌之间的空间关系研究。【方法】运用地学统计学方法求得天敌和害虫各自的变程,用灰色关联度方法分析害虫与天敌变程的关联度,关联度值越大的天敌在空间上对害虫的跟随关系越密切。并分析比较害虫的同一种天敌与该害虫空间跟随关系密切程度年度间差异的原因。【结果】8种天敌中,与害虫跟随关系密切的前3位天敌,2015年八点广翅蜡蝉的天敌是粽管巢蛛Clubiona japonicola Boes.et Str(0.859 3)、斜纹猫蛛Oxyopes sertatus L.Koch(0.805 8)、草间小黑蛛Erigonidium graminicolum Sundevall(0.804 7),2016年的是草间小黑蛛(0.806 2)、鳞纹肖蛸Tetragnatha squamata Karsch(0.792 9)、茶色新圆蛛Neoscona theisi Walckenaer(0.792 2),两年间前3位天敌中只有草间小黑蛛一种相同。2015年茶尺蠖的天敌是粽管巢蛛(0.7909)、八斑球腹蛛Theridion octomaculatum Boes.et Str(0.790 4)、斜纹猫蛛(0.789 4),2016年的是茶色新圆蛛(0.877 7)、草间小黑蛛(0.872 0)、粽管巢蛛(0.823 0),两年间前三位天敌中也只有粽管巢蛛一种相同。2015年花蓟马的天敌是斜纹猫蛛(0.890 0)、八斑球腹蛛(0.878 9)和粽管巢蛛(0.843 5),2016年的是锥腹肖蛸Tetragnatha maxillosa Thorell(0.879 7)、八斑球腹蛛(0.866 5)和粽管巢蛛(0.855 3),两年间前3位天敌中有八斑球腹蛛和粽管巢蛛2种天敌相同,且位次相同。2015年茶蚜的天敌是锥腹肖蛸(0.819 9)、茶色新圆蛛(0.816 4)和鳞纹肖蛸(0.814 2),2016年的是茶色新圆蛛(0.840 7)、三突花蟹蛛Misumenops tricuspidatus Fabr(0.814 7)和八斑球腹蛛(0.806 8),两年间前3位天敌中只有茶色新圆蛛一种相同。【结论】初步分析表明年度间与害虫跟随关�[Objectives] To protect and utilize natural enemies, and develop more scientific sampling methods, spatial relationships among natural enemies of Ricania speculum, Ectropis obliqua, Frankliniella intonsa and Toxoptera aurantii Boyer were investigated in the ＂Baihaozao＂ tea gardens in suburban Hefei, China in 2015 and 2016. [Methods] Ranges of spatial dependence（RSDs） of natural enemies were calculated using geostatistics and the spatial relationships among predators and pests were analyzed using grey relational analysis. This paper analyzes why the spatial distribution of natural enemies of insect pests closely match that of their hosts. [Results] Relational grade analysis indicated that the spatial distribution of the three main natural enemies, Clubiona japonicola（0.859 3）, Oxyopes sertatus（0.805 8） and Erigonidium graminicolum（0.804 7） closely matched that of Ricania speculum in the ＂baihaozao＂ tea garden in 2015. However, in 2016, the three main enemies were Erigonidium graminicolum（0.806 2）, Tetragnatha squamata（0.792 9） and Neoscona theisi（0.792 2）, i.e. only one of the top three predators was the same in both years. The spatial distribution of Clubiona japonicola（0.790 9）; Theridion octomaculatum（0.790 4） and Oxyopes sertatus（0.789 4） also closely matched that of Ectropis obliqua in 2015, but in 2016 the three main enemies were Neoscona theisi（0.877 7）, Erigonidium graminicolum（0.872 0） and Clubiona japonicola（0.823 0）. Again, only one of the top three predators was the same in both years. The spatial distribution of Oxyopes sertatus（0.890 0）, Theridion octomaculatum（0.878 9） and Clubiona japonicola（0.843 5） closely matched that of Frankliniella intonsa in 2015, but in 2016 the three main enemies included Tetragnatha maxillosa（0.879 7）, Theridion octomaculatum（0.866 5） and Clubiona japonicola（0.855 3）; only two of the top three predators was the same in both years although their relative ranking was the same.
