摘　　要：苹果绵蚜Eriosoma lanigerum (Hausmann)是苹果上重要害虫,为探求苹果园苹果绵蚜的防治适期及粘虫胶带阻隔法的防控效果,2021年和2022年对苹果园苹果绵蚜及其重要的寄生性天敌日光蜂和捕食性天敌异色瓢虫的种群数量动态进行了系统调查,同时研究了粘虫胶带阻隔处理对苹果绵蚜种群数量动态的影响并计算出苹果绵蚜高峰日和全年的防治效果。结果表明:每年的5月中下旬苹果绵蚜进入到发生高峰期,在此期间日光蜂的寄生率较低,仅为30%左右,异色瓢虫零星发生,田间自然天敌的控制作用不明显,需进行防控,防治适期为5月上中旬;粘虫胶带阻隔能显著降低苹果绵蚜高峰期的种群数量,2021年对苹果绵蚜高峰日和全年的防治效果分别为57.05%和51.57%,而2022分别为63.19%和68.94%。说明粘虫胶带阻隔法对苹果绵蚜具有一定防控效果。Woolly apple aphid,Eriosoma lanigerum(Hausmann)is an important pest on apple.To identify the suitable period for the control of E.lanigerum in the apple orchard and study the control effect of sticky bands barrier methods,we set up the sticky band barrier treatments and systematically investigated the population dynamics of E.lanigerum and its natural enemies,Aphelinus mali(Haldeman)and Harmonia axyridis(Pallas),in 2021 and 2022.The results showed that the peak period of the aphid occurrence began in mid to late May each year.During this period,the parasitism rate of A.mali was low,which was only about 30%,and H.axyridis occurred sporadically,indicating that the control effect of the parasitoid in the field was not obvious,and the appropriate control period was early May.The barrier of sticky bands could significantly reduce the aphid population in the peak period,and the control effect on the peak day and the whole year were 57.05%and 51.57%respectively in 2021,while those in 2022 were 63.19%and 68.94%,respectively.It means that the sticky band barrier methods had a certain control effect on apple aphids.
