摘　　要：为更好地利用黄色黏虫板诱集回迁桃园的秋迁蚜、降低桃园的越冬卵量,于2017、2018年在山西省晋中市太谷区不同桃园进行了黄板诱蚜试验。结果表明,桃蚜、桃粉蚜的秋迁蚜从9月下旬开始向桃园转移,10月为回迁高峰期;黄板悬挂的最佳高度和最佳密度分别为2 m和375块/hm^(2),与对照区相比,悬挂黄板可使桃树枝条上蚜虫的越冬卵量下降73.6%;此外,黄板诱集秋迁蚜对桃园天敌昆虫没有影响,回迁高峰期最高益害比仅为1∶113.3。可见,黄板诱集秋迁蚜可有效降低桃园蚜虫的越冬卵量,同时对天敌安全。因此,在桃蚜和桃粉蚜发生且存在季节性寄主转移的地区,可利用黄板诱杀秋迁蚜,以降低其危害。To control autumn-migrating aphids returning to the peach orchard and reduce the abundance of overwintering eggs quantity of autumn migrant aphid in the peach orchard,the trapping effects of yellow sticky traps were studied in different peach orchards in Taigu district,Jinzhong city,Shanxi province in 2017,2018.The results showed that the autumn-migrating aphids of Myzus persicae and Hyalopterus amygdali began to transfer to the peach orchard from late September,and the peak occured in October.The optimal hanging height and density for the yellow sticky traps were 2 m and 375 pieces/hm^(2),respectively,compared with the control area,the overwintering eggs of aphids on the branches of peach trees decreased by 73.6%when the yellow trops were hung.In addition,yellow sticky traps attract autumn migration aphid had no significantly effect on the natural enemies in the peach orchard.The maximum ratio of beneficial arthropods to pests(B/P)was only 1∶113.3 during the aphid migration peak.Therefore,yellow sticky traps effectively decreased the occurrence of the overwintering eggs,which was safe for the natural enemies in the peach orchard.Therefore,the yellow sticky traps can be used to control these two aphids in the region where seasonal host transfer occurs,and reduce the harm.
