Lethal effects of sulfuryl fluoride on eggs of different ages and other life stages of the warehouse moth Ephestia elutella (Hübner)

Sulfuryl fluoride (SF) is a fumigant used for the control of stored-product pest insects and is a feasible alternative to some uses of methyl bromide. SF was first registered in Germany in 2004 for disinfestation of emptied flourmills, emptied food storages and dried fruit. One- to 4-day-old eggs, larvae and pupae of the warehouse moth, Ephestia elutella (Hübner) (Lepidoptera) were investigated for their susceptibility to SF under different conditions. Each life stage was exposed for 18 h, 24 h or 48 h, to 11.6 g/m3 or 21.3 g/m3 at 15 °C, 20 °C or 25 °C and 65% relative humidity. A Fourier transform infrared (FTIR) spectrometer was used to determine the concentrations of SF. Within 18 h of exposure, all larvae and pupae of E. elutella died at 11.6 g/m3 at all three temperatures. The 1 and 2- day-old eggs were generally more susceptible, whereas the 3 and 4-day-old eggs were more tolerant to the SF treatment. All eggs of all ages were controlled within 48 h of exposure to the concentration of 21.3 ± 1.3 g/m3 at temperatures of 20 °C and 25 °C.
