为了合理保护和利用天敌,开展了潜山县茶园假眼小绿叶蝉Empoasca vitis、通草粉虱Dialeurodes citri、茶黄蓟马Scirtothrips dorsalis和茶蚜Toxopetera aurantii与其主要天敌之间空间关系的研究.运用地学统计学方法分析天敌和害虫空间变程,应用灰色关联度分析方法分析害虫与天敌变程的关联度,得出以下结果:与假眼小绿叶蝉空间跟随关系密切的前2位天敌是八点球腹蛛Theridion octomaculatum和斑管巢蛛Clubiona reichlini;与通草粉虱空间跟随关系密切的前2位天敌是八点球腹蛛和草间小黑蛛Erigonidium graminicolum;与茶黄蓟马跟随关系密切的前2位天敌是草间小黑蛛和八点球腹蛛;与茶蚜跟随关系密切的前2位天敌是异色瓢虫Harmonia axyridis和草间小黑蛛.
In order to rationally protect and utilize natural enemies, the spatial relationships among Empoasca vitis, Dialeurodes citri, Scirtothrips dorsalis and Toxopetera aurantii and their major natural enemies in Qianshan tea plantation were studied. Statistical methods were used to analyze the spatial variability of natural enemies and pests. Gray relational analysis method was used to analyze the association degree between pests and natural enemies, and the following results were obtained: The first two natural enemies closely related to the space of green leafhoppers Theridion octomaculatum and Clubiona reichlini; the first two natural enemies closely related to the spatial distribution of M. tabaci were Erigonidium graminicolum, an eight-pod ball and closely related to the yellow thrips The first two natural enemies were black grasshopper and black-bone spider, and the first two natural enemies closely related to tea aphid were Harmonia axyridis and black grass spider.
