摘要
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.
To protect and utilize natural enemies reasonably , spatial relationships between natural enemies and Empoasca vitis, Dialeurodes citri, Scirtothrips dorsalis and Toxopetera aurantii were investigated re-spectively in tea plantations in Qianshan , Anhui.The ranges of spatial dependence ( RSDs) of these pests and their natural enemies were calculated by GIS and the spatial relationships among natural ene -mies and four pests were analyzed using grey relational analysis .The results showed that two main natural enemies ( Theridion octomaculatum and Clubiona reichlini) had a close spatial following relationship with Empoasca vitis.The synthetic results demonstrated that two natural enemies ( Theridion octomaculatum and Erigonidium graminicolum) had a close sptial relationship with Dialeurodes citri, while two main nat-ural enemies of Scirtothrips dorsalis were Erigonidium graminicolum and Theridion octomaculatum in spa-To protect and utilize natural enemies reasonably , spatial relationships between natural enemies and Empoasca vitis, Dialeurodes citri, Scirtothrips dorsalis and Toxopetera aurantii were investigated re-spectively in tea plantations in Qianshan , Anhui.The ranges of spatial dependence ( RSDs) of these pests and their natural enemies were calculated by GIS and the spatial relationships among natural ene -mies and four pests were analyzed using grey relational analysis .The results showed that two main natural enemies ( Theridion octomaculatum and Clubiona reichlini) had a close spatial following relationship with Empoasca vitis.The synthetic results demonstrated that two natural enemies ( Theridion octomaculatum and Erigonidium graminicolum) had a close sptial relationship with Dialeurodes citri, while two main nat-ural enemies of Scirtothrips dorsalis were Erigonidium graminicolum and Theridion octomaculatum in spa-tial relationships .And the two close natural enemies of Toxopetera aurantii were Harmonia axyridis and Erigonidium graminicolum in space .
