【目的】系统调查黄山大叶种茶园4种主要害虫假眼小绿叶蝉Empoasca vitis、茶蚜Toxoptera aurantii、萤叶甲类Galerucinae和八点广翅蜡蝉Ricaniaspeculum及其捕食性天敌的种群动态.【方法】应用灰色关联度法和生态位分析法分析4种害虫与其天敌在数量、时间和空间的关系,应用密切指数之和综合评判4种害虫的天敌优势种.【结果和结论】春夏季与秋冬季之间4种害虫的优势种天敌差别较大.春夏季假眼小绿叶蝉前3位的优势种天敌是斜纹猫蛛Oxyopes sertatus、茶色新园蛛Neoscona theisi和锥腹肖蛸Tetragnatha maxillosa;茶蚜前3位的优势种天敌是异色瓢虫Leis axyridis、龟纹瓢虫Propylea japonica和锥腹肖蛸;萤叶甲类前3位的优势种天敌是龟纹瓢虫、异色瓢虫和草间小黑蛛Erigonidium graminicolum;八点广翅蜡蝉前3位的优势种天敌是粽管巢蛛Clubiona japonicola、锥腹肖蛸和鞍形花蟹蛛Xysticus ephippiafus.秋冬季假眼小绿叶蝉前3位的优势种天敌是锥腹肖蛸、八点球腹蛛Theridion octomaculatum和鳞纹肖蛸Tetragnatha squamata;茶蚜前3位的优势种天敌是锥腹肖蛸、八点球腹蛛和鳞纹肖蛸;萤叶甲类前3位的优势种天敌是龟纹瓢虫、异色瓢虫和锥腹肖蛸;八点广翅蜡蝉前3位的优势种天敌是茶色新园蛛、斜纹猫蛛和鞍形花蟹蛛.
【Objective】 The objective of this study was to systematically investigate the population dynamics of four dominant pests such as Empoasca vitis, Toxoptera aurantii, Galerucinae and Ricaniaspeculum and their predatory natural enemies. Methods The relationship between quantity, time and space of four kinds of pests and their natural enemies was analyzed by gray relational analysis and niche analysis, and the dominant species of four kinds of pests were evaluated synthetically by the sum of indices. 【Result and Conclusion】 Spring summer and summer The dominant species of the dominant pests differed greatly among the four pests in autumn and winter.The dominant species of the dominant species of the three dominant green-leafhoppers in spring and summer were Oxyopes sertatus, Neoscona theisi and Tetragnatha maxillosa; The predominant dominant species of the tea aphid were Leis axyridis, Propylea japonica and Conchophyllum scoparium. The dominant species of the first three members of the Tea Aphid family were Propylaea japonica, And Erigonidium graminicolum, and the dominant species of the first three species of the eight-point Waxwing were the Clubiona japonicola, Xylocodylidae and Xysticus ephippiafus The predominant dominant species of the three dominant green-leafhoppers in this season were Theodion octomaculatum and Tetragnatha squamata. The predators of the first three dominant species of tea aphid were cone beetle, The dominant species of the first three species of Diabrotica were Coprinus comatus, Harmonia axyridis and Coprinus comatus; the predominant species predators of the eight Is a new brown garden spider, twisting cat spider and saddle crab spider.
