摘　　要：2018—2022年3月下旬至10月中旬,在四川雅安市名山区3个茶树主栽品种名山特早213、福鼎大白茶和名山白毫131的茶园内,采用棋盘式取样法分别采取茶蓬不同部位叶片,镜检并计录害螨种类及数量,每7天调查1次。调查结果表明,当地茶园主要害螨为茶橙瘿螨、茶跗线螨和柑橘始叶螨;茶橙瘿螨和茶跗线螨主要分布于芽下2、3叶,柑橘始叶螨主要分布于成熟新叶和中下部老叶。茶橙瘿螨和柑橘始叶螨主要发生于4—6月,茶跗线螨可发生于5—7月和9月,同一茶园内,茶跗线螨发生晚于茶橙瘿螨和柑橘始叶螨。因此,4—7月和9月为茶园主要害螨发生高峰期,应加强监测预警和防控。The species and occurrence dynamics of the main mite pests were investigated in the tea gardens of Ya'an,Sichuan Province.From late March to mid-October in 2018-2022,the populations of major mite pests were investigated every seven days in three main tea cultivars(Camellia sinensis),MingshanTezao 213,Fuding Dabai,and Mingshan Baihao 131,by chessboard sampling method from different parts of the tea canopy.The species of mite pests and their populations were counted by microscopic examination,and the data were analyzed using Excel software.The results showed that the main mite pests in these tea gardens were Acaphylla theae,Polyphagotarsonemus latus,and Eotetranychus kankitus.A.theae and P.latus were mainly found in the second and third leaves below the bud,and E.kankitus was mainly found in the mature new leaves and middle and lower old leaves.A.theae and E.kankitus occurred mainly from April to June,and P.latus occurred from May to July and September.In the same tea garden,the occurrence of P.latus was later than that of A.theae and E.kankitus.Therefore,the monitoring and control of the main mite pests in the tea garden should be intensified from April to July and September.
