为判断溴甲烷和硫酰氟对舞毒蛾不同虫态的杀灭效果,天津出入境检验检疫局科研人员在25℃下,分别在经过气密性检测的熏蒸桶内投入16、20、24、32克/立方米的溴甲烷和40、56、72、88克/立方米的硫酰氟,熏蒸处理舞毒蛾卵、1龄幼虫、蛹和成虫4.5小时。结果表明,经过4.5小时熏蒸,杀灭舞毒蛾卵、1龄幼虫、蛹和成虫的溴甲烷浓度分别为32、 In order to determine the killing effect of methyl bromide and sulfuryl fluoride on different insect states of Gypsy moths, researchers from Tianjin Entry-Exit Inspection and Quarantine Bureau put in 16, 20, 24, 32 G / m 3 of methyl bromide and 40, 56, 72, and 88 g / m 3 of sulfuryl fluoride, fumigated with Gypsy moth eggs, first instar larvae, pupae and adults for 4.5 hours. The results showed that after 4.5 hours of fumigation, the methyl bromide concentrations of the first instar larvae, pupal and adult adults were 32,
