Abstract:In order to clarify the types of natural enemies that are closely related in Empoasca vitis at space, and to provide scientific basis for rational use and protection of natural enemies. Therefore we here use geostatistics analysis method to calculate the statistics of semivariogram of Empoasca vitis and its main 6 natural enemies in Baihaozao Tea Garden, Huangshan large-leaf Tea Garden, Nongkangzao Tea Garden, Pingyangtezao Tea Garden, and Wuniuzao Tea Garden in autumn and winter. We firstly use the gray system analysis method to analyze the gray correlation degree of the calculation results, and then used the analysis results are standardized. The standardized closeness index is used to judge the closeness of the spatial relationship between natural enemies and Empoasca vitis. The result is that:1) the top three natural enemies that are closely related to the Empoasca vitis in Huangshan large-leaf Tea Garden and Nongkangzao Tea Garden are the Clubiona japonicola, Tetragnatha squamata, and Oxyopes sertatus, but they have different orders. 2) The top three natural enemies of Baihaozao Tea Garden are the Tetragnatha squamata, Oxyopes sertatus, and Tetragnatha maxillosa. The first two species of natural enemies are the same as the Huangshan large-leaf Tea Garden and Nongkang Zao Tea Garden. 3) The top three natural enemies of Pingyangtezao Tea Garden are Tetragnatha squamata, Clubiona japonicola, and Erigonidium graminicolum. The first two species of natural enemies are the same as Huangshan large Leaf Tea Garden and Nongkang zao Tea Garden. 4) The top three natural enemies of Wuniuzao Tea Garden are Clubiona japonicola, the Erigonidium graminicolum and Misumenops tricuspidatus. Among the six dominant species of natural enemies, only the Clubiona japonicola is the same as Huangshan large-leaf Tea Garden and Nongkangzao Tea Garden natural enemy species. According to the sum of the close indices of the natural enemies' species in the five tea gardens and the ranking of the same species of natural enemies, the natural enemies closely related to the Empoasca vitis are all the Tetragnatha squamata, Clubiona japonicola and Oxyopes sertatus. After our investigation and research, we came to the conclusion that the change in the ranking of natural enemies is mainly caused by the change in the ratio of the number of pests to natural enemies. The smaller ratio of the number of individual pest to the number of individual natural enemy, the closer of follow-up relationship between natural enemies and pests is. The close reason is related to the shortage of bait resources.
