摘　　要：探讨蜘蛛类天敌与茶尺蠖(Ectropis obliqua hypulina)的空间关系和数量关系,为茶园茶尺蠖的综合治理提供科学依据。于2021年7月8日至2021年9月17日对安徽农业大学国家高新技术农业园安吉白茶、黄山大叶种、龙井43、农抗早、平阳特早和乌牛早茶园的茶尺蠖及其天敌进行种群数量调查。运用地学统计学方法结合角余弦系数法、密切指数和灰色关联度法对6种茶园茶尺蠖幼虫及其天敌种群动态进行分析,研究蜘蛛类天敌与茶尺蠖空间和数量关系的密切程度。根据密切指数之和得出,6种茶园中与茶尺蠖幼虫空间关系密切的前2位蜘蛛依次是鳞纹肖蛸(Tetragnatha squamata)和三突花蟹蛛(Misumenops tricuspidatus),与茶尺蠖幼虫数量关系密切的前2位蜘蛛依次是草间小黑蛛(Erigonidium graminicolum)和鳞纹肖蛸。综合分析得出,与茶尺蠖幼虫在空间和数量上关系密切的前3位蜘蛛依次是鳞纹肖蛸、八点球腹蛛(Theridion octomaculatum)和三突花蟹蛛,鳞纹肖蛸是6种茶园中茶尺蠖幼虫最主要的自然蜘蛛类天敌。研究结果可以为合理保护和利用蜘蛛类天敌提供重要科学依据。To exlore the spatial and quantitative relationship between natural enemy of spiders and Ectropis obliqua hypulina,so as to provide scientific basis for the comprehensive management of E.obliqua hypulina in tea garden.From July 8 to September 17 in 2021,the population of E.obliqua hypulina and its natural enemy in National High Tech Agricultural Park of Anhui Agricultural University,including Anji albino tea,Huangshan large leaf,Longjing 43,Nongkangzao,Pingyangtezao and Wuniuzao.The population dynamics of E.obliqua hypulina larvae and their natural enemy in 6 tea gardens were analyzed by using geostatistics,angle cosine coefficient method,closeness index and grey correlation degree,and the close degree of spatial and quantitative relationship between spider natural enemy and E.obliqua hypulina were studied.According to the sum of closeness index of the 6 tea gardens,the top 2 spiders closely related to the space of E.obliqua hypulina were Tetragnatha squamata and Misumenops tricuspidatus.The top 2 spiders closely related to the number of E.obliqua hypulina were Erigonidium graminicolum and T.squamata.According to the comprehensive analysis,the top 3 spiders closely related to the space and number of E.obliqua hypulina were T.squamata,Theridion octomaculatum and M.tricuspidatus.T.squamata was the most important natural spider natural enemy of E.obliqua hypulina in 6 tea gardens.The results provided a reference for the biological control,rational protection and utilization of spider natural enemy of E.obliqua hypulina.
