Abstract: All life stages of Sitophilus granarius, as well as the fungi Fusarium avenaceum and Fusarium culmorum, were tested for their susceptibility to different exposure times and concentrations of carbonyl sulfide (COS) at 20°C and 70% r.h. Complete kill of S. granarius occurred at concentrations of 18 g m^-3 COS for 120 h or 32 g m^-3 COS for 72 h. The eggs were most tolerant to the toxic gas, followed by pupae and adults, whereas larval stages were most susceptible to the fumigant. Sublethal dosages prolonged the developmental periods of the immature life stages. Dosages lethal to S. granarius caused growth inhibition in F. avenaceum and F. culmorum, although the fungi recovered fully after treatment. In the presence of high relative humidity, COS was presumably degraded partly to H₂S, which caused corrosion on copper. The possibility was discussed of COS being an alternative to methyl bromide.
