遗憾的是，它也和许多已被人类淘汰的其它熏蒸剂一样，由于它属于消耗大气臭氧层的物质[1]，为了保护人类子孙万代良好的生活环境，已经在国际上取得共识，把它列为逐步淘汰的物质[2]，而且已于1979年开始采取了具体的法规性行动[3][4]。

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.

主要研究结果如下：1、甲酸乙酯和二甲基二硫对仓储害虫具有良好的控制作用，应加快甲酸乙酯替代溴甲烷防治仓储害虫开发应用，同时，二甲基二硫是很有潜力的仓储害虫防治熏蒸剂，要深入进行二甲基二硫控制有害生物的技术研究，以期获得新的溴甲烷替代熏蒸剂。2、利用循环熏蒸系统测定了甲酸乙酯、二甲基二硫和甲硫醚对米象Sitophilus oryzaeL。
