绿色Myzus persicae（Sulzer）是一种重要的全球性害虫，广泛危害园艺和粮食作物。控制M。桃蚜主要依赖杀虫剂，然而，该物种具有很高的发展杀虫剂抗性的倾向，并且已经发展了对来自世界各地不同化学组的80多种杀虫剂的抗性。在澳大利亚，M.桃蚜种群是常见的。鉴于M.为了迅速建立对新化学品的抗性，需要在新杀虫剂广泛使用之前监测其敏感性的程序。在这项研究中，我们使用浸叶生物测定法，以产生敏感性数据，并调查潜在的交叉抗性在多个领域收集的人口澳大利亚M。烟蚜对两种最近注册的杀虫剂氟啶虫酰胺和阿非啶虫酮的敏感性。暴露144和168 h后，M.烟粉虱种群对氟啶虫酰胺或阿非啶虫酮的敏感性，并且没有证据表明田间敏感性发生变化。此外，没有证据表明氟啶虫酰胺或阿非啶虫酮与氨基甲酸酯、拟除虫菊酯、有机磷酸酯和烟碱类杀虫剂的多种已知抗性机制之间存在交叉抗性。在田间抗性演变之前，本研究中产生的敏感性数据为未来的抗性监测提供了一个有用的起点，并允许制定和实施杀虫剂抗性管理策略，这些策略应延长氟啶虫酰胺和阿非啶虫酮对M.桃蚜。
The green peach aphid, Myzus persicae (Sulzer) is a significant global pest of a broad range of horticultural and grain crops. Control of M. persicae is primarily dependent on insecticides, however, this species has a high propensity to evolve insecticide resistance and has evolved resistance to over 80 insecticides from various chemical groups worldwide. In Australia, widespread resistance to carbamates, organophosphates, pyrethroids and neonicotinoids in M. persicae populations is commonplace. Given the ability of M. persicae to establish resistance to new chemistries quickly, programs are needed to monitor susceptibility to new insecticides before their widespread use. In this study, we used leaf-dip bioassays to generate sensitivity data and investigate potential cross-resistance in multiple field-collected populations of Australian M. persicae to two recently registered insecticides, flonicamid and afidopyropen. After 144 and 168 h exposure, we found little variation in the susceptibility of M. persicae populations to either flonicamid or afidopyropen, and no evidence of sensitivity shifts in the field. Additionally, there was no evidence of cross-resistance between flonicamid or afidopyropen and multiple known resistance mechanisms for carbamate, pyrethroid, organophosphate and neonicotinoid insecticides. The sensitivity data generated in this study prior to the evolution of field resistance provides a useful starting point for future resistance monitoring, and allows for the development and implementation of insecticide resistance management strategies which should prolong the long-term efficacy of flonicamid and afidopyropen against M. persicae.
