Fumigant Effect of Sulfuryl Fluoride on Ephestia elutella (Hübner) with Different Life Stages in Tobacco Warehouse

Sulfuryl fluoride (SF) is a new, safe, and effective fumigant used to control pest and insects. The fumigant effect of SF on Ephestia elutella (Hübner) (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.
