摘要： 为了判断多种害虫各自的主要天敌,通过对茶园害虫及其天敌的系统调查,对害虫和天敌调查 数据用灰色关联度分析法、生态位分析法和空间格局聚集强度指数分析法进行分析,以明确江淮丘陵茶 园的主要害虫种类 。综合排序表明 :假眼小绿叶蝉的主要天敌是八斑球腹蛛、锥腹肖蛸蛛和鞍型花蟹蛛; 茶蚜的主要天敌是龟纹瓢虫、异色瓢虫和薄翅螳螂 ;茶白粉虱的主要天敌是茶色新圆蛛、大草蛉和异色 瓢虫 。3种主要害虫中的假眼小绿叶蝉和茶白粉虱种群聚集均数λ值都大于2,说明其聚集是本身原因 引起的 ;而茶蚜的λ值小于2,说明其聚集是环境中某些因子引起的 。
Abstract: To determine the major natural enemies of pests,the tea pests and their natural enemies were investigated systematically,and the survey data of the pests and natural enemies were further studied using grey correlation analysis,ecological niche analysis and spatial pattern of aggregation intensity index analysis to identify the major kinds of major pests in Jianghuai hilly tea plantation . The synthetic ranking result indicated that the main natural enemies of Empoasca vitis were Theridion octomaculatum,Tetragnatha maxillosa and Xysticusephippiatus;the main natural enemies of Toxoptera aurantii were Propylaea japonica,Harmonia axyridis and Mantis religiosa;and the main natural enemies of Pealius akebiaewere Neoscona theis,Chrysopa septempunctata and Harmonia axyridis . Gathering averages of E . vitis and P . akebiae of major three pests were greater than two due to the aggregated nature of the insect,while that of T . aurantii was less than two due to the certain environmental factors .
