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.
