摘　　要：针对枸杞蚜虫对常规农药产生抗药性且难于防治的现状,选用5种药剂进行大田药效试验,结果表明,0.5%苦参碱水剂800倍液、10%氟啶虫酰胺水分散性粒剂3 000倍液和10%溴氰虫酰胺可分散油悬浮剂800倍液对枸杞蚜虫有较好的防治效果,具有一定的速效性和持效性,药后1 d的防治效果分别达到54.49%、59.04%和62.75%,药后15 d的防治效果分别为88.83%、78.19%和76.73%,3种药剂的防治效果均高于20%呋虫胺可溶粒剂800倍液和70%吡虫啉水分散性粒剂7 000倍液,这两种药剂1 d和15 d的防治效果仅为29.14%、54.49%和32.63%、28.70%。氟啶虫酰胺和溴氰虫酰胺两种新型蚜虫防治药剂,可作为防治枸杞蚜虫的药剂进行使用;苦参碱属于生物农药,近几年在农业上广泛应用,且有良好的防治效果,可作为枸杞绿色防控和蚜虫发生前期的预防药剂。Aiming at the current situation that wolfberry aphids were resistant to conventional pesticides and difficult to control, 5 kinds of insecticides were selected to carry out field efficacy tests. The results showed that,0.5%matrine aqueous solution 800 times liquid, 10% flulidinamide aqueous dispersible granule 3 000 times liquid and10% cyananamide dispersible oil suspension 800 times liquid had better control effect on wolfberry aphids, and have certain quick-acting and sustained effect. The control effects of the three agents were 54.49%, 59.04% and62.75% at 1 day after administration, 88.83%, 78.19% and 76.73% at 15 days after administration, respectively.The control effects of the three agents were higher than 20% dinotefuran soluble tablets 800 times liquid and 70%imidacloprid aqueous dispersive tablets 7 000 times liquid. The control effects of these two agents on 1 day and 15 days were 29.14%, 54.49% and 32.63%, 28.70%, respectively. Flonicamid and Cyantraniliprole can be used as a medicament for controlling aphids. Matrine is a biopesticide, widely used in agriculture in recent years, and has good control effect, can be used as green control of wolfberry and aphids in the early stage of prevention.
