摘要
为利用天敌有效防治茶园蓟马,2015-2016年选择安徽农业大学农业科技试验基地的白毫早和乌牛早2种茶园进行试验,对2种茶园的蓟马数量及其天敌数量进行调查,采用地学统计学方法与灰色关联度法相结合方法综合分析与蓟马空间跟随关系密切的天敌种类。结果表明,2015年和2016年2年,白毫早茶园蓟马共2408头,其捕食性天敌共12156头,与蓟马空间跟随关系密切的前4位天敌依次是锥腹肖蛸Tetragnatha maxillosa、茶色新圆蛛Neoscona theisi、粽管巢蛛Clubiona japonicola和草间小黑蛛Erigonidium graminicolum,2年密切指数之和分别为1.952、1.843、1.800和1.751;2015年和2016年2年,乌牛早茶园蓟马共6540头,其捕食性天敌共12376头,与蓟马空间关系密切的前4位天敌依次是八斑球腹蛛Theridion octomaculatum、异色瓢虫Harmonia axyridis、茶色新圆蛛和锥腹肖蛸,2年密切指数之和分别为1.863、1.829、1.762和1.759。综合分析2年白毫早和乌牛早2种茶园,与蓟马空间关系密切的前4位天敌依次是锥腹肖蛸、茶色新圆蛛、异色瓢虫和草间小黑蛛,密切指数之和为3.710、3.605、3.512和3.473。
In order to use natural enemies to effectively control thrips,two tea gardens(Baihaozao and Wuniuzao)in the Agricultural Science and Technology Experimental Base of Anhui Agricultural University were selected for experiment in 2015 and 2016.The numbers of thrips and their natural enemies in the two tea gardens were investigated,and the geostatistics method and grey correlation method were used to comprehensively analyze the natural enemy species closely related to thrips in spatial-following relationships.The results showed that there were 2408 thrips,and 12156 predatory natural enemies in Baihaozao tea garden in 2015 and 2016.The most four natural enemies closely related with the thrips in spatial-following relationships were Tetragnatha maxillosa,Neoscona theisi,Clubiona japonicola and Erigonidium graminicolum,with a total closeness index in two years of 1.952,1.843,1.800 and 1.751,respectively.There were 6540 thrips,and 12376 predatory natural enemies in Wuniuzao tea garden in2015 and 2016,and the most four enemies closely related with the thrips in spatial-following relationships were Theridion octomaculatum,Harmonia axyridis,N.theisi and T.maxillosa,with a total closeness index in two years of 1.863,1.829,1.762 and 1.759,respectively.The comprehensive analysis showed that T.maxillosa,N.theisi,H.axyridis and E.graminicolum were the most four enemies closely related with thrips in spatial-following relationships in Baihaozao and Wuniuzao tea gardens in 2015 and 2016,with a total closeness index of 3.710,3.605,3.512 and 3.473,respectively.
