Sulfoxaflor is a newly released fourth-generation neonicotinoid insecticide for management of sap-feeding pests that have developed resistance to established insecticide groups. The risk of resistance developing to this pesticide in target pests is unclear. We selected a strain of the green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae), for resistance to sulfoxaflor in the laboratory, which showed 199-fold resistance after 45 generations compared to the starting population. Life table analysis showed that the resistant strain had a fitness of 0.83 compared to the susceptible strain. Adult longevity of the resistant strain was reduced by 9.55% compared to the susceptible strain. The period when adults of the resistant strain produced offspring was reduced by 17.19%, while the mean fecundity of the resistant strain was reduced by 15%. These findings suggest that M. persicae can develop a high level of resistance to sulfoxaflor, but fitness costs may result in a recovery of sensitivity when field populations are no longer exposed to sulfoxaflor.
