[Aim]  To assess the baseline susceptibility of Tuta absoluta to seven insecticides; tetraniliprole, chlorantraniliprole, lambda-cyhalothrin, dinotefuran, spinetoram, emamectin benzoate, and indoxacarb, and the current level of resistance to these insecticides among populations of this species in Shanxi Province. [Methods]  The leaf-dipping method was used to establish the baseline sensitivity of a susceptible, laboratory population of T. absoluta to the seven insecticides. Levels of resistance to these insecticides among five T. absoluta populations in Shanxi Province were also determined. [Results]  All five Shanxi populations had low susceptibility to lambda-cyhalothrin and dinotefuran (LC₅₀ values generally > 300 mg/L), but were sensitive to most of the other insecticides. Populations from Linyi (LY) and Dingxiang (DX) showed reduced susceptibility to tetraniliprole, whereas those from Taigu (TG) and Shangdang (SD) had low-level resistance to tetraniliprole (resistance ratios of 5.176 and 5.384, respectively). The Taigu population had also developed low-level resistance to emamectin benzoate (resistance ratio of 6.174). [Conclusion]  Populations of T. absoluta in Shanxi province remain susceptible to most of the insecticides tested, although they are relatively resistant to lambda-cyhalothrin and dinotefuran. The effectiveness of tetraniliprole and emamectin benzoate should be closely monitored, and these should only be used in rotation with other insecticides to delay the potential development of resistance.
