摘　　要：为了探究捕食小贯小绿叶蝉Empoasca onukii的游猎蛛的种间竞争作用,调查2021年‘平阳特早’‘乌牛早’‘龙井43’‘农抗早’‘安吉白茶’和‘黄山大叶种’6个茶园盛发期小贯小绿叶蝉与其天敌游猎蛛的种群动态,运用通径分析法、灰色关联度法和竞争系数法分析不同游猎蛛之间竞争作用并得出竞争力最强的游猎蛛,再将灰色关联度与竞争系数相结合引申出竞争强度指数的概念以验证所得结果的准确性。结果表明,取食高峰日小贯小绿叶蝉时,黑色蝇虎Plexippus paykulli和斑管巢蛛Clubiona deletrix竞争力最强,条纹蝇虎Plexippus setipes竞争力最弱。研究结果为合理保护和利用游猎蛛防治小贯小绿叶蝉提供科学依据。To explore interspecific competition among wandering spiders feeding on Empoasca onukii in tea plantations,population dynamics of E.onukii and its natural enemies in‘Pingyangtezao’‘Wuniuzao’‘Longjing 43’‘Nongkangzao’‘Anjibaicha’and‘Huangshandayezhong’tea plantations were investigated.The most competitive spiders were analyzed by using path analysis method,gray correlation method and competition coefficient method,and then the concept of competition intensity index was derived by combining gray correlation and competition coefficient to verify the accuracy of the obtained results.The results showed that Plexippus paykulli and Clubiona deletrix were the most competitive,while Plexippus setipes was the least competitive,when feeding on E.onukii,which provided a scientific basis for the reasonable protection and use of wandering spiders to control E.onukii.
