【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。
【Objective】 The objective of this study was to determine the predominant species of natural enemies of the white pearl and Monolipta hieroglyphica and Brevipalpus obovatus in the early tea plantation of Wuniu. 【Method】 By using parallel jump method, 30 sample plots were randomly selected in the tea plantation to investigate and record the number of species and individuals of pests and natural enemies. The gray relational degree and niche analysis were used to analyze the distributions of 2 major pests, , The relationship between the species of Diabrotica philoxeroides and the 11 kinds of natural enemies in quantity, time and space. 【Result】 The results showed that the predominant predators of the 6 dominant species of Parasitized Ovipodiaceae were Misumenops tricuspidatus, Tetragnatha squamata, Erigonidium graminicolum, Theridion octomaculatum, Tilapia spider Clubiona japonicola and the dumpling tube nest spider Oxyopes sertatus, Wuniu morning tea garden are Scylla serrata, the broad leg bee Brachymeria obscurata, the three Prothalia crab spider, amber new spider Neoscona theisi, cone belly Tetragnatha maxillosa And black grass spider, the same natural enemy ratio of 50%. White cephalophoric tea garden double-spotted long flutter Diabrotica A predominant species predators are eight-point ball abdominal spider, grass black spider, scales Xiao Zan, Zong pipe nest spider, broad leg wasp and brown new spider, black Cattle early tea garden were black grasshopper spider, cone Xiao Shao, Scylla serrata, the new brown spider spider, wasps and dumplings tube nest spider, the same natural enemy ratio was 83.33%. 【Conclusion】 The same cumulative rate of natural enemies increased with the increase of natural enemy species, indicating that the effect of tea tree species on the dominant natural enemies of short ovoid mites was greater than that of the native species Pterophylla niloticus.
