摘　　要： 硫酰氟是国内外新推的一种安全、高效的害虫熏蒸剂。笔者采用薄膜密闭法,研究了硫酰氟对烟垛4种虫态烟草粉螟的熏杀效果。研究结果表明,硫酰氟对4种虫态烟草粉螟均具有很高的熏杀活性。用15 g/m3硫酰氟分别熏杀幼虫、蛹及成虫12 h,试虫的校正死亡率均为100.00%,以15 g/m3硫酰氟熏杀卵48 h,卵的校正死亡率为93.46%。4种虫态的烟草粉螟以成虫和幼虫对硫酰氟的敏感性最高,蛹次之,卵的敏感性最低。硫酰氟可作为一种有效的熏蒸剂用于防治烟仓烟草粉螟。 Sulfuryl fluoride （SF） is a new, safe, and effective fumigant used to control pest and insects. The fumigant effect of SF on Ephestia elutella （Hiibner） （Lepidoptera： Pyralididae） with four life stages were studied in tobacco stack sealed with plastic film. The result indicated that SF had excellent fumigant activities on four life stages of the tested pests. After treated with SF for 12 h at 15 g/m3, the corrected mortalities of adult, larva and pupae of the E. elutella were up to 100.00%, and the corrected mortality of E. elutella egg was 93.46% after treated for 48 h at 15 g/m3. four life stages of E. elutella, the adult and larva had the highest susceptibility to SF, followed by pupae and egg. SF might be used as an effective fumigant for control of E. elutella in tobacco warehouse.
