化学品被广泛用于保护大田作物免受蚜虫害虫和蚜虫传播的病毒性疾病的侵害。其中一个物种是桃蚜（Myzus persicae）（Sulzer），这是一种全球性害虫，攻击各种农作物并传播许多具有经济破坏性的植物病毒。由于在世界许多地方广泛和重复使用化学品，该物种已进化出对大量杀虫剂化合物的抗性。在这项研究中，我们调查了一种新的植物保护产品，螺虫乙酯，化学控制失败后，抗性的演变。我们的研究提供了明确的表型和基因型证据螺虫乙酯抗性的人群中的M。来自澳大利亚的persicae。我们发现，在同一化学组中，对其他杀虫剂，即螺甲螨酯和螺螨酯存在交叉抗性。我们还证明了耐药性与先前报道的螺虫乙酯乙酰辅酶A羧化酶靶位点A2226V突变有关。我们的基因分析发现所有耐药M。桃蚜种群属于相同的多位点克隆类型，并携带A2226V突变，这似乎是作为该物种的显性性状遗传的。我们的发现为A2226V赋予的抗性提供了新的见解，并对M.在澳大利亚和世界各地的桃。在这项研究中开发的诊断方法应作为一个有价值的工具，为未来的抗性监测和支持害虫管理战略的实施。© 2022作者有害生物管理科学由John Wiley & Sons Ltd代表化学工业协会出版。桃蚜对除草剂的抗药性在世界许多地方都很普遍。这包括对螺虫乙酯（和其他第23组化合物）的耐药性，我们发现这与乙酰辅酶A羧化酶的突变有关。这种突变，A2226V，似乎是遗传作为一个显性性状在这个物种。
Chemicals are widely used to protect field crops against aphid pests and aphid‐borne viral diseases. One such species is Myzus persicae (Sulzer), a global pest that attacks a broad array of agricultural crops and transmits many economically damaging plant viruses. This species has evolved resistance to a large number of insecticide compounds as a result of widespread and repeated chemical use in many parts of the world. In this study, we investigated the evolution of resistance to a new plant protection product, spirotetramat, following reported chemical control failures. Our study provides clear phenotypic and genotypic evidence of spirotetramat resistance in populations of M. persicae from Australia. We show there is cross‐resistance to other insecticides within the same chemical group, namely spiromesifen and spirodiclofen. We also demonstrate that resistance is associated with the previously reported mutation, A2226V in the target site of spirotetramat, acetyl‐CoA carboxylase. Our genetic analysis found all resistant M. persicae populations belong to the same multi‐locus clonal type and carry the A2226V mutation, which appears to be inherited as a dominant trait in this species. Our findings provide new insight into the resistance conferred by A2226V and have implications for the control of M. persicae in Australia and worldwide. A diagnostic assay developed in this study should serve as a valuable tool for future resistance monitoring and to support the implementation of pest management strategies. © 2022 The Authors. Pest Management Science published by John Wiley & Sons Ltd on behalf of Society of Chemical Industry. Insecticide resistance in Myzus persicae is commonplace in many parts of the world. This now includes resistance to spirotetramat (and other Group 23 compounds), which we show is associated with a mutation in acetyl‐CoA carboxylase. This mutation, A2226V, appears to be inherited as a dominant trait in this species.
