摘　　要：为了科学施药,合理利用和保护自然天敌进行茶黄蓟马Scirtothrips dorsalis的综合防治,用灰色系统分析方法、生态位分析方法和空间格局聚集强度指标分析方法对大别山区茶园缨翅目茶黄蓟马与捕食性天敌在数量、时间、空间格局等方面进行分析,综合排序的结果表明:茶黄蓟马的主要捕食性天敌依次是草间小黑蛛Erigonidium graminicolum、八斑球腹蛛Theridion octomaculatum、锥腹肖蛸Tetragnatha maxillosa、龟纹瓢虫Propylaea japonica和斑管巢蛛Clubiona reichini.茶黄蓟马种群聚集均数(λ)大于2,其聚集是害虫本身原因造成的,天敌的λ均小于2,其聚集是环境因子所致.The analyses on the quantity, time and spatial patterns of Scirtothrips dorsalis and the natural enemies were conducted with grey system analysis, ecological niche analysis and collective intention analysis of spatial framework in order to protect and use of natural enemies rationally. The synthetic ranking results indicated that the dominant natural enemies of S. dorsalis were in the order of Erigonidium graminicolum, Theridion octomaculatum, Tetragnatha maxillosa, Propylaea japonica and Clubiona reichini. The gathering average of S. dorsalis was greater than two due to the natural aggregation of the pests, while gathering averages of natural enemies were less than two due to the environmental factors.
