Abstract： To determine the control efficacy of spraying S -methoprene against tobacco beetle （Lasioderma serricorne） and its impact onthequalityof tobacco leaves during strippingandre-drying processlaboratorytests wereconducted todetect the biological activity of variousconcentrationsof Sα -methoprenesprayed on tobacco stripsagainst tobacco beetle，and S -methoprenewassprayed usingspecialiedspraerduringleaf sringadre-drying procesforaalyingcontroleicacyagainstbacobetleas wellas thechemicalcompositionsandsensoryqualityoftobaccostrips.Resultsshowedasthefolows.（1）Theemergenceratesof tobacco beetle reached 7.78% when the concentration of S -methoprenewas 1.25mg/kg ，while the emergence rates exhibited zerowhen the concentration was over 5mg/kg （2） Seven days after the spraying of 15mg/kg S-methoprene on the leaf stripping and re-drying line， the emergence rate of tobacco beetle introduced averaged only 2.49% （compared to 93.33% in the control group）， and one year after the storage of flue-cured tobacco treated with S -methoprene， the average emergence rate was 3.07% . （3）The inhibitory efficacy of Sλ methoprene sprayed on the leaf stripping and re-drying line against adult tobacco beetle was over 95% . （4） Spraying 15mg/kgS. methopreneon leaf strippngandre-drying line had no significantimpactonthechemicalcompositions and sensoryqualityof tobacco leaves. The application of S -methoprene via spraying on the leaf stripping and re-drying line can effectively control tobacco storage pests.
