摘　　要：以桃树桃蚜为试材,通过田间试验比较22.4%螺虫乙酯悬浮剂、22%氟啶虫胺腈悬浮剂、99%矿物油乳油、60%吡蚜酮水分散粒剂4种药剂对其防治效果。结果表明,22.4%螺虫乙酯悬浮剂4500倍和22%氟啶虫胺腈悬浮剂5000倍液药后1d的防效虽差异显著,但防效很低,速效性差;药后14 d的防效均在97%以上,显著好于99%矿物油乳油100倍、60%吡蚜酮水分散粒剂4000倍液,表现出很好的持效性。60%吡蚜酮水分散粒剂4000倍液的速效性差,持效性可达70%以上。99%矿物油乳油100倍液的速效性、持效性都很差。在桃树安全生产中,建议轮换使用22%氟啶虫胺腈悬浮剂、22.4%螺虫乙酯悬浮剂和60%吡蚜酮水分散粒剂适时防治,不建议使用99%矿物油乳油。Myzus persicae was used as the test material,four insecticides were used for the investigation of the control effects against Myzus persicae in field.The results showed that there was a significant difference between the control effect of 22.4%Spirotetramat SC 4500 times and 22%Sulfoxaflor SC 5000 times on the first day after treatment,but the control effect was very low and the rapid action was poor.After 14 days,the control effect was above 97%,which was significantly better than that of 99%mineral oil emulsion 100 times and 60%Pymetrozine WG 4000 times,60%Pymetrozine WG 4000 times of the quick effect is poor,the persistence can reach more than 70%.The quick effect and the persistence of the 99%mineral oil emulsion100 times are poor.Conclusion:In the safe production of peach trees,it is recommended to use 22%Sulfoxaflor SC,22.4%Spirotetramat SC and 60%Pymetrozine WG to control peach aphid timely,and it is not recommended to use 99%mineral oil emulsion to control peach aphid.
