Sulfoxaflor is a newly released fourth-generation neonicotinoid insecticide for management of sap-feeding peststhat have developed resistance to established insecticide groups. The risk of resistance developing to this pesticidein 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 after45 generations compared to the starting population. Life table analysis showed that the resistant strain had afitness 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 reducedby 17.19%, while the mean fecundity of the resistant strain was reduced by 15%. These findings suggestthat M. persicae can develop a high level of resistance to sulfoxaflor, but fitness costs may result in a recovery ofsensitivity when field populations are no longer exposed to sulfoxaflor.
