It is necessary to carry out a thorough study on pest control technology with DMDS, with an expectation of obtaining a new fumigant of methyl bromide alternative.2. Investigation of the toxicity of fumigation on adult and mixed stages of the three most tolerant insect species -- Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum -- under a range of EtF、DMS and DMDS doses in a Flow-through Fumigation System shows that the FTFS procedure offers a constant concentration of fumigant with low CO2 concentrations and ensures that the fumigant toxicity is effectively not compromised by CO2. In comparison with chamber fumigation method, the toxicity data of EtF、DMS and DMDS obtained from this experiment is more accurate by using FTFS.
