摘　　要：针对苹果黄蚜防治药剂类型单一、药剂敏感性下降等问题,采用浸叶法开展几种药剂对苹果黄蚜室内毒力测定,并用共毒系数法进行联合毒力评价。结果显示,氟啶虫胺腈和阿维菌素在8∶1~1∶8、氟啶虫胺腈和吡虫啉1∶1、氟啶虫胺腈和高效氯氟氰菊酯在4∶1~1∶4配比范围对苹果黄蚜有增效作用,3种组合最佳增效比均为1∶1。田间应用结果显示,药后3~21 d,22%氟啶虫胺腈SC单剂对苹果黄蚜防效达94.77%~99.40%;22%氟啶虫胺腈SC分别与5%阿维菌素EC、70%吡虫啉WG和2.5%高效氯氟氰菊酯EW按有效成分1∶1混配后对苹果黄蚜防效达86.43%~97.00%,均显著高于相应单剂对照,持效期可达21 d。推荐采用氟啶虫胺腈单剂及氟啶虫胺腈与阿维菌素、吡虫啉或高效氯氟氰菊酯混配剂作为替代药剂防治苹果黄蚜。Aiming at the problems of few insecticide varieties and the decreased insecticide sensitivity,the combined toxicities of several insecticides to Aphis citricola were measured by slide slip method and evaluated by co-toxicity coefficient method.The results showed that the mixture ratios of sulfoxaflor and abamectin in 8∶1-1∶8,sulfoxaflor and imidacloprid in 1∶1,sulfoxaflor and lambda-cyhalothrin in 4∶1-1∶4 were synergistic combinations to A.citricola,and the optimum synergistic ratio of the three combinations was 1∶1.Field trials indicated that the control efficiency of sulfoxaflor 22%SC against A.citricola were 94.77%-99.40%after 3 to 21 days,and that of the mixture of sulfoxaflor 22%SC with abamectin 5%EC,imidacloprid 70%WG or lambda-cyhalothrin 2.5%EW was 86.43%-97.00%,significantly higher than that of the single control agent,and the persistence was 21 days.Accordingly,sulfoxaflor and the three synergistic combinations could be recommended as alternative insecticides to control A.citricola.
