摘要
为明确茶园天敌与假眼小绿叶蝉Empoasca vitis之间关系的变化动态,用灰色关联度法和生态位法研究天敌与假眼小绿叶蝉在数量、时间、空间上的关系,综合分析假眼小绿叶蝉优势种天敌位次在茶树品种间和年份间的差异。结果显示,根据密切指数之和比较发现,2015年在乌牛早茶园与白毫早茶园中,与假眼小绿叶蝉跟随关系密切的前3位天敌中均有锥腹肖蛸Tetragnatha maxillosa和粽管巢蛛Clubiona japonicola,这2种天敌在2种茶园中的密切指数之和分别为5.493和5.784;2016年天敌中均有八斑球腹蛛Theridion octomaculatum和粽管巢蛛,这2种天敌在2种茶园中密切指数之和分别为5.296和5.448。2015年与2016年相比,乌牛早茶园前3位天敌中均有粽管巢蛛,白毫早茶园前3位天敌中均有锥腹肖蛸和粽管巢蛛。表明2个品种茶园不同年份假眼小绿叶蝉前3位优势种天敌为粽管巢蛛、锥腹肖蛸和八斑球腹蛛。
In order to define the dynamics of the relationships between the natural enemies and smaller green leafhopper Empoasca vitis,their relationships between natural enemies and E.vitis in number,time and space were studied by using grey relational degree method and ecological niche method.The differences in the natural enemies between the species of tea tree varieties and years were analyzed.The first three natural enemies closely related with E.vitis included Tetragnatha maxillosa and Clubiona japonicola in Wuniuzao and Baihaozao tea gardens in 2015.The total closeness index of T.maxillosa and C.japonicola in two tea gardens were 5.493 and 5.784,respectively.The natural enemies Theridion octomaculatum and C.japonicola were also observed in 2016.The total closeness index of Th.octomaculatum and C.japonicola were 5.296 and 5.448,respectively.Compared with 2015 and 2016,the first three natural enemies in Wuniuzao tea garden included C.japonicola.The first three natural enemies included T.maxillosa and C.japonicola in Baihaozao.The results indicated that the first three natural enemies closely related with the Empoasca vitis were C.japonicola,T.maxillosa and Th.octomaculatum.
