    白毫早和乌牛早茶园卵形短须螨和双斑长跗萤叶甲优势种天敌的差异

    Differences of dominant natural enemies of Monolepta hieroglyphica and Brevipalpus obovatus in Baihaozao and Wuniuzao tea gardens

      摘要
    • 摘要:
      目的 明确白毫早和乌牛早茶园卵形短须螨Monolepta hieroglyphica和双斑长跗萤叶甲Brevipalpus obovatus的优势种天敌。
      方法 采用平行跳跃法, 在茶园随机选取30个样方, 调查并记录害虫及天敌物种数和个体数; 应用灰色关联度和生态位分析法分析茶园中2种主要害虫卵形短须螨、双斑长跗萤叶甲与11种天敌在数量、时间和空间上的关系。
      结果 白毫早茶园卵形短须螨前6位优势种天敌分别是三突花蟹蛛Misumenops tricuspidatus、鳞纹肖蛸Tetragnatha squamata、草间小黑蛛Erigonidium graminicolum、八点球腹蛛Theridion octomaculatum、斜纹猫蛛Clubiona japonicola和粽管巢蛛Oxyopes sertatus, 乌牛早茶园分别是鳞纹肖蛸、广大腿小蜂Brachymeria obscurata、三突花蟹蛛、茶色新圆蛛Neoscona theisi、锥腹肖蛸Tetragnatha maxillosa和草间小黑蛛, 相同天敌比率为50%。白毫早茶园双斑长跗萤叶甲前6位优势种天敌是八点球腹蛛、草间小黑蛛、鳞纹肖蛸、粽管巢蛛、广大腿小蜂和茶色新圆蛛, 乌牛早茶园分别是草间小黑蛛、锥腹肖蛸、鳞纹肖蛸、茶色新圆蛛、广大腿小蜂和粽管巢蛛, 相同天敌比率为83.33%。
      结论 天敌的累计相同比率随着天敌种类的增加而增加, 表明茶树品种对卵形短须螨优势种天敌的影响大于对双斑长跗萤叶甲的。

       

      Abstract:
      Objective To determine the dominant natural enemies of Monolepta hieroglyphica and Brevipalpus obovatus in Baihaozao and Wuniuzao tea gardens.
      Method A total of 30 quadrats were randomly selected in Baihaozao and Wuniuzao tea gardens using parallel jumping method.The numbers of species of pests and their natural enemies, and individuals of each species were recorded.Grey correlation degree method and niche analysis method were applied to analyze the relationships between two pest species, M.hieroglyphica and B.obovatus, and eleven species of natural enemies in quantity, occurring time and space.
      Result The top six species of natural enemies of M.hieroglyphica in Baihaozao tea garden were Misumenops tricuspidatus, Tetragnatha squamata, Erigonidium graminicolum, Theridion octomaculatum, Clubiona japonicola and Oxyopes sertatus, and in Wuniuzao tea garden were T.squamata, Brachymeria obscurata, M.tricuspidatus, Neoscona theisi, Tetragnatha maxillosa and E.graminicolum.The overlapping natural enemies between two tea gardens accounted for 50% of the total.The top six natural enemies of B.obovatus in Baihaozao tea garden were T.octomaculatum, E.graminicolum, T.squamata, O.sertatus, B.obscurata and N.theisi, and in Wuniuzao tea garden were E.graminicolum, T.maxillosa, T.squamata, N.theisi, B.obscurata and O.sertatus.The overlapping natural enemies between two tea gardens accounted for 83.33% of the total.
      Conclusion The cumulative ratio of overlapping natural enemies between two tea gardens increases as the number of species of natural enemies increases.The influences of tea tree varieties on dominant natural enemies are higher for M.hieroglyphica compared to B.obovatus.
