摘      要：Sitobion avenae(F.) and Rhopalosiphum padi(L.) are two important pests of wheat in *** typically coexist in fields during the late period of wheat *** is a novel sulfoximine insecticide that demonstrates broad-spectrum efficacy,especially in targeting sap-feeding *** study was carried out to investigate the sublethal effects of sulfoxaflor on the development,longevity,and reproduction of two species of wheat *** results showed that sublethal concentrations of sulfoxaflor did not cause significant effects on the fecundity or the longevity of the parent generation(F0 generation) of either *** or ***,it caused transgenerational sublethal *** ***,adult longevity of F1 generation was significantly *** significant differences were observed on the population parameters of *** in the F1 *** ***,the adult preoviposition period(APOP) and the total preoviposition period(TPOP) of F1 generation were significantly *** mean generation time(T) was significantly reduced in the *** F1 ***’s more,the intrinsic rate of increase(rm) and the finite rate of increase(λ) were significantly increased in the *** F1 *** together,these results suggest that exposure to the LC25 of sulfoxafl had no effects on the parent generation of *** or ***,but it reduced adult longevity of *** as a negative effect and increased the rm and λ of *** in the first progeny generation,which may have an impact on the population dynamics of ***.
