| description | The brown marmorated stink bug, <i>Halyomorpha halys</i>, has become a severe threat to agriculture worldwide with continuous invasion and spread. Sulfoxaflor is the pioneering sulfoximine insecticide and has been widely employed for managing sap-feeding insect pests across diverse crops. However, the sublethal effects of sulfoxaflor on the growth and reproduction of <i>H. halys</i> remain unexplored. This study employed age-stage life tables and physiological parameters to evaluate the sublethal effects of sulfoxaflor on <i>H. halys</i>. The bioassay results indicated that the LC<sub>20</sub> and LC<sub>50</sub> values of sulfoxaflor against second-instar nymphs of <i>H. halys</i> were 7.75 and 20.97 mg/L, respectively. Treatment with the LC<sub>20</sub> concentration of sulfoxaflor reduced the lifespan of female adults by 11.74 days. Importantly, the oviposition period of females was shortened by 9.47 days, and the fecundity was decreased by 1.4-fold. Additionally, the activities of cytochrome P450 (P450s) and glutathione <i>S</i>-transferase (GSTs) enzymes in <i>H. halys</i> were enhanced 1.40 and 1.54 times after treatment with sublethal concentrations of sulfoxaflor. These findings demonstrate that sublethal concentrations of sulfoxaflor significantly inhibit the population development of <i>H. halys</i>. Moreover, the detoxification enzymes P450s and GSTs may be associated with the potential resistance to sulfoxaflor in <i>H. halys</i>. This information provides valuable insights into the application of sulfoxaflor in the management of this pest. |
