摘　　要：为了科学施药,合理利用和保护天敌进行假眼小绿叶蝉、通草粉虱、黑刺粉虱和茶蚜的综合防治,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潜山县茶园4种半翅目主要害虫与其捕食性天敌在数量、时间、空间格局等方面进行分析,评判出害虫的主要天敌,与假眼小绿叶蝉数量上跟随关系密切的天敌是三突花蟹蛛、斑管巢蛛、鞍型花蟹蛛、茶色新圆蛛和八点球腹蛛;时间上是三突花蟹蛛、斑管巢蛛、鞍型花蟹蛛、八点球腹蛛和茶色新圆蛛;空间上是三突花蟹蛛、斑管巢蛛、草间小黑蛛、八点球腹蛛和茶色新圆蛛;把与假眼小绿叶蝉在数、时、空方面参数大小的序号积加,和最小的即是第一位天敌,其综合排序得出假眼小绿叶蝉的主要捕食性天敌依次是三突花蟹蛛、斑管巢蛛、八点球腹蛛、茶色新圆蛛和鞍型花蟹蛛。与通草粉虱数量上跟随关系密切的天敌是锥腹肖蛸、日本球腹蛛、草间小黑蛛、龟纹瓢虫和八点球腹蛛;时间上是龟纹瓢虫、锥腹肖蛸、草间小黑蛛、八点球腹蛛和日本球腹蛛;空间上是八点球腹蛛、草间小黑蛛、龟纹瓢虫、异色瓢虫和三突花蟹蛛;把与通草粉虱在数、时、空方面参数大小的序号积加,综合排序得出通草粉虱的是龟纹瓢虫、草间小黑蛛、八点球腹蛛、锥腹肖蛸和异色瓢虫。与黑刺粉虱数量上跟随关系密切的天敌是草间小黑蛛、锥腹肖蛸、八点球腹蛛、异色瓢虫和鞍型花蟹蛛;时间上是草间小黑蛛、八点球腹蛛、锥腹肖蛸、异色瓢虫和斑管巢蛛;空间上是八点球腹蛛、草间小黑蛛、异色瓢虫、锥腹肖蛸和龟纹瓢虫;把与黑刺粉虱在数、时、空方面参数大小的序号积加,综合排序得出黑刺粉虱的是八点球腹蛛、草间小黑蛛、锥腹肖蛸、异色瓢虫和斑管巢蛛。与茶蚜数量上跟随关系密切的天敌是异色�At present, the major insect pests of Hemiptera in tea gardens are Empoasca vitis, Dialeurodes citri, Aleurocanthus spiniferus and Taxopetera aurantii. To scientifically utilize and conserve enemies for integrated control of insect pests of tea, in the present work, the quantity as well as temporal and spatial patterns of the four major pests of tea and their natural enemies in Qianshan area, Anhui province were systematically studied using grey system analysis, ecological niche analysis and aggregated-intensity index analysis of spatial patterns. The results showed that the orders of the closely followed natural enemies of Empoasca vitis were Misumenops tricuspidatus, Clubiona reichin, Xysticus ephippiatus, Neoscona theisi and Theridion octomaculatum in quantity, Misumenops tricuspidatus , Clubiona reichini , Xysticus ephippiatus , Theridion octomaculatum and Neoscona theisi in time, as well as Misumenops tricuspidatus, Clubiona reichin, Erigonidium graminicolum, Theridion octomaculatum and Neoscona theisi in space, respectively. The synthetic ranking results indicated the orders of main natural enemies of Empoasca vitis were Misumenops tricuspidatus, Clubiona reichini, Theridion octomaculatum, Neoscona theisi and Xysticus ephippiatus. For Dialeurodes cirri, the orders of its closely followed natural enemies were, respectively, Tetragnatha maxillosa , Enoplognatha japonica, Erigonidium graminicolum , Propylaea japonica and Theridion octomaculatum in quantity, Propylaea japonica, Tetragnatha maxillosa , Erigonidium graminieolum, Theridion octomaculatum and Enoplognatha japonica in time, and Theridion octornaculatum, Erigonidium graminicolum, Propylaea japonica, Harmonia axyridis and Misumenops tricuspidatus in space. And the synthetic ranking results demonstrated that the orders of main natural enemies of Dialeurodes citri were Propylaea japonica, Erigonidium graminicolum, Theridion octomaculatum, Tetragnatha maxillosa and Harmonia axyridis. The further analysis showed that the orders of the closely followed natu
