本课题以空集装箱为实验场所,研究了溴化甲烷熏蒸消毒、杀虫、灭鼠实验效果,其杀灭能力按杀灭小白鼠、德国小蠊成虫、德国小蠊卵荚、细菌繁殖体、细菌芽胞的顺序由大到小排列,所需剂量时间乘积相差200倍以上(10～2400g/h/m~3);同时还分析了剂量为20g/m~3时溴化甲烷浓度时间乘积(CT值)与消毒效果之间的相关关系,并进行曲线拟合。建议采用低剂量、短时间熏蒸(20g/m~3,4h)进行杀虫、灭鼠也可取得较满意效果。
The subject of empty container as the experimental site, studied the fumigation of methane bromide fumigation, insecticide, rodent control experimental results, its killing ability according to kill mice, adult German cockroaches, German cockroach egg pods, bacterial propagules, The sequence of bacterial spores was arranged in descending order, the difference of the product of time required dose was more than 200 times (10 ~ 2400g / h / m ~ 3), and the product of methane concentration time CT value) and disinfection effect, and curve fitting. Proposed low-dose, short-term fumigation (20g / m ~ 3,4h) insecticide, rodent control can also be more satisfactory results.
