| 为了合理保护和充分利用天敌，明确茶园游猎蛛天敌捕食茶尺蠖Ectropis obliqua hypulina的种间竞争力及其差异。本文运用通经分析法、灰色关联度分析法、竞争系数分析法及竞争强度指数分析法对龙井43、黄山大叶种、乌牛早、安吉白茶、平阳特早和农抗早6类茶园中茶尺蠖高峰日时的7种游猎蛛捕食茶尺蠖的种间竞争作用进行分析。结果表明，按相关系数比较，乌牛早茶园茶尺蠖与条纹蝇虎Plexippus setipet的相关系数为-0.888，平阳特早茶园茶尺蠖与三突花蟹蛛Misumenops tricuspidatus和斜纹猫蛛Oxyopes Sertatws的相关系数分别为0.981和-0.902，均达相关水平，天敌间鞍型花蟹蛛Xysticus ephippiafus、三突花蟹蛛、斑管巢蛛Clubiona reichlini和斜纹猫蛛均与黑色跳蛛Plexippus paykulli相关，鞍型花蟹蛛、粽管巢蛛Clubiona japonicola和黑色跳蛛均与三突花蟹蛛相关。用灰色关联度法分析，与茶尺蠖数量上关系密切的前4种天敌依次是三突花蟹蛛、粽管巢蛛、黑色跳蛛和鞍型花蟹蛛。按竞争系数大小比较，前4种天敌依次是黑色跳蛛、粽管巢蛛、斑管巢蛛和三突花蟹蛛。按竞争强度指数大小比较，前4种天敌依次是黑色跳蛛、粽管巢蛛、斑管巢蛛和三突花蟹蛛。综合分析4种方法的结果，各类茶园中7种游猎蛛中竞争力强的前4种天敌分别是黑色跳蛛、粽管巢蛛、斑管巢蛛和三突花蟹蛛。本研究结果可为合理保护和充分利用游猎蛛绿色防控茶尺蠖提供重要的科学依据。 |

| In order to protect and make full use of the natural enemies, we should clarify the the interspecific competitiveness and differences of the natural enemies of hunting spiders in tea gardens in feeding on E.obliqua hypulina.Therefore we used general meridian analysis method, gray system analysis method, competitive coefficient analysis method and competitive intensity index method to analyze the competitive effect of hunting spiders feeding on E.obliqua hypulina in Longjing 43 Tea Garden, Huangshan large-leaf Tea Garden, Wuniuzao Tea Garden, Anji albino-tea Tea Garden, Pingyangtezao Tea Garden and Agricultural anti-zao Tea Garden. The results showed that, according to the correlation coefficient comparison, the correlation coefficient between E.obliqua hypulina and Plexippus setipet was -0.888 in Wuniuzao Tea Garden, and the correlation coefficient between E.obliqua hypulina and Misumenops tricuspidatus and Oxyopes sertatus were 0.981 and -0.902 in Pingyangtezao Tea Garden, respectively, which reach the correlation level. Xysticus ephippiafus,Misumenops tricuspidatus, Clubiona reichlini and Oxyopes sertatus were all related to P.setipet. X.ephippiafus, Clubiona japonicola and P.setipet were all related to M.tricuspidatus. We used grey correlation method to analyze, top four natural enemies that closely related to E.obliqua hypulina in number were M.tricuspidatus, C.japonicola, P.setipet and X.ephippiafus. According to comparison of competition coefficient, top four natural enemies were P.setipet, C.japonicola, C.reichlini and M.tricuspidatus. According to the competition intensity index, top four natural enemies were P.setipet, C.japonicola, C.reichlini and M.tricuspidatus. Based on the results of four analysis methods, top four competitive natural enemies among seven hunting spiders were P.setipet, C.japonicola, C.reichlini and M.tricuspidatus. These results provided an important scientific basis for the rational protection and green prevention and control of natural enemies of E.obliqua hypulina. |
