【目的】 了解S-烯虫酯对重要储粮害虫持续处理的控制作用效果。【方法】 采用滤纸药膜法测定S-烯虫酯处理后4种重要储粮害虫（赤拟谷盗 Tribolium castaneum、杂拟谷盗Tribolium confusum、锈赤扁谷盗Cryptolestes ferrugineus和锯谷盗Oryzaephilus surinamensis）的幼虫存活率、幼虫死亡率、蛹期存活率、蛹期死亡率和羽化率。【结果】 S-烯虫酯持续处理4周后，锈赤扁谷盗和锯谷盗均得到有效控制，最高羽化率不超过10.00%；持续处理6周后，赤拟谷盗处理组大部分在幼虫期死亡，仅当S-烯虫酯处理剂量为2×10^﹣5 mg/cm²时，赤拟谷盗处理组羽化率最高为61.67%。S-烯虫酯处理剂量为4×10^﹣5 mg/cm²持续处理7周后，仅杂拟谷盗有羽化现象，羽化率为41.67%。与对照组相比，处理组4种储粮害虫的幼虫期和蛹期均有不同程度延长，且随S-烯虫酯处理剂量增加其生长发育历期呈延长趋势。【结论】 S-烯虫酯对4种重要储粮害虫均有一定控制作用，对不同害虫的控制作用效果与处理时间和处理剂量密切相关。

[Aim]  To understand the effects of continuous exposure to S-methoprene on four major stored grain pests. [Methods]  Insecticide-impregnated filter paper was used to measure the larval survival rate, larval mortality rate, pupal survival rate, pupal mortality rate, and emergence rate of four major stored grain pests (Tribolium castaneum, Tribolium confusum, Cryptolestes ferrugineus, and Oryzaephilus surinamensis) after S-methoprene treatment. [Results]  Four weeks of continuous treatment with S-methoprene effectively controlled both C. ferrugineus and O. surinamensis, both of which had a maximum emergence rate of < 10.00%. Most T. castaneum larvae died after 6 weeks of continuous treatment. The T. castaneum emergence rate reached a maximum of 61.67% only at an S-methoprene dosage of 2×10^–5 mg/cm². Only T. confusum had an emergence rate of 41.67% after 7 weeks of continuous treatment at a dosage of 4×10^–5 mg/cm². Compared to the control groups, the larval and pupal stages of all four stored grain pests treated with S-methoprene were prolonged to varying degrees, and this prolongation increased with increasing S-methoprene dosage. [Conclusion]  S-methoprene can control, to some extent, all four major stored grain pests tested, but the degree of control is closely related to the treatment duration and dosage.
