中文摘要: 【目的】 为了明确与广翅蜡蝉Ricania speculum空间上跟随关系密切的优势种天敌,为合理保护和利用自然天敌防治广翅蜡蝉提供科学依据。【方法】 用地学统计学法和灰色关联度法相结合,综合评判与广翅蜡蝉在空间上跟随关系密切的优势种天敌。【结果】 年度间比较,2015年和2016年乌牛早茶园与广翅蜡蝉空间跟随关系密切的前四位天敌依次是鳞纹肖蛸Tetragnatha squamata、锥腹肖蛸Tetragnatha maxillosa、茶色新圆蛛Neoscona theisi和八斑球腹蛛Theridion octomaculatum。2015年和2016年白毫早茶园与广翅蜡蝉空间跟随关系密切的前四位天敌依次是粽管巢蛛Clubiona japonicola、八斑球腹蛛、茶色新圆蛛和草间小黑蛛Erigonidium graminicolum。两茶树品种间比较,广翅蜡蝉前四位天敌中相同的天敌,2015年是锥腹肖蛸和粽管巢蛛,2016年是草间小黑蛛和八斑球腹蛛。【结论】 对两种茶园2015年和2016年密切指数总和及序号总和的综合分析,与广翅蜡蝉空间上跟随关系密切的前三位天敌是八斑球腹蛛、粽管巢蛛和茶色新圆蛛。研究结果明确了两种茶园合理利用和保护蜘蛛天敌的种类。
英文摘要:

 [Objectives]  To identify the dominant natural enemies of Ricania speculum and to provide a scientific basis for the comprehensive protection and utilization of such species for the control of this pest. [Methods]  Geo-statistics and grey correlation were used to analyze the spatial relationships between R. speculum and its natural enemies in two tea plantations in 2015 and 2016. [Results]  The four natural enemies whose spatial distributions were most closely correlated with that of R. speculum in the Wuniuzao tea plantation were Tetragnatha squamata Karsch, Tetragnatha maxillosa, Neoscona theisi and Theridion octomaculatum. The four natural enemies whose spatial distributions were most closely correlated with that of R. speculum in the Baihaozao tea plantation were Clubiona japonicola Boes. et Str, Theridion octomaculatum, Neoscona theisi and Hylyphantes graminicola. The four natural enemies whose spatial distributions were most closely correlated with that of R. speculum were the same in two tea varieties; in 2015, these were T. maxillosa and C. japonicola and in 2016, they were Hylyphantes graminicola and T. octomaculatum. [Conclusion]  Comprehensive analysis, including close index summation and serial number summation, indicate that the three natural enemies whose spatial distributions were most closely correlated with that of R. speculum in both tea plantations in both years, were T. octomaculatum, C. japonicola and N. theisi. These results promote the rational use and protection of natural enemies of R. speculum.
