摘　　要：为了合理保护和利用自然天敌进行害虫的综合防治,对安徽茶园主要害虫与天敌进行系统调查,进行了天敌对花蓟马和茶短须螨跟随效应的研究。运用地学统计学方法求得天敌与害虫半变异函数的变程,用灰色关联度分析方法分析变程之间的关联度,与害虫关联度值越大的天敌对害虫的跟随关系越密切。本文分析了花蓟马种群数量在全年最多时段(4月13日—7月8日)、茶短须螨种群数量在全年最多时段(5月13日—8月5日)内,茶园中5种主要天敌对两种害虫跟随关系的密切程度。结果表明,花蓟马与斜纹猫蛛、八点球腹蛛、粽管巢蛛、龟纹瓢虫和异色瓢虫半变异函数变程的关联度分别为0.658 3、0.614 6、0.607 1、0.753 8和0.647 1,茶短须螨与斜纹猫蛛、八点球腹蛛、粽管巢蛛、龟纹瓢虫和异色瓢虫半变异函数变程的关联度分别为0.718 9、0.615 6、0.701 0、0.676 5和0.697 6。表明与花蓟马跟随关系密切的天敌依次是龟纹瓢虫、斜纹猫蛛和异色瓢虫,与茶短须螨跟随关系密切的天敌依次是斜纹猫蛛、粽管巢蛛和异色瓢虫。In order to reasonably protect and utilize natural enemies for pest control,system survey of main pests and natural enemies was conducted in tea garden.Then the spatial relationships of Frankliniella intonsa and Brevipalpus obovatus with their predators were analyzed using the method of geostatistics and grey relational analysis.The ranges of spatial dependence(RSD S)of natural enemies and insect pests were separately calculated by the method of geostatistics,and the spatial relationships among enemies and pests were analyzed using grey relational analysis.The greater the correlation value,the closer relationships between enemies and pest.In this study,we analyzed F.intonsa and its enemies from April 13 to July 8 and B.obovatus from May 13 to August 5,at which the quantity of pests were great.The results showed that the relational grade of semivariogram RSDs of F.intonsa,Oxyopes sertatus,Theridion octomaculatum,Clubiona japonicola,Propylea japonica and Leis axyridis were 0.658,0.614 6,0.607 1,0.753 8 and 0.647 1,respectively.The relational grade of semivariogram RSDs of B.obovatus,O.sertatus,T.octomaculatum,C.japonicola,P.japonica and L.axyridis were 0.718 9,0.615 6,0.701 0,0.676 5 and 0.697 6,respectively.It was determined that the natural enemies of F.intonsa with closest spatial relationships were P.japonica,O.sertatus and L.axyridis,and the natural enemies of B.obovatus with closest spatial relationships were O.sertatus,C.japonicola and L.axyridis.
