摘　　要：以广东口岸进口原木和废纸上携带的红火蚁Solenopsis invicta Buren为杀灭对象,测定了溴甲烷对其的熏蒸效果。在空箱内分别按6.01、12.01、22.52、25.53、28.53、31.53、34.53及37.54g/m3的浓度投药;在实箱内分别按25.53、28.53及31.53g/m3的浓度投药,每个处理分别熏蒸2,4,6和8h,试验结果表明:在空箱内投药浓度为34.53、28.53和22.52g/m3时分别熏蒸4、6及8h,货柜箱内的红火蚁全部被杀灭。在实箱内投药浓度为31.53、28.53、及25.53g/m3时分别熏蒸4、6及8h,均能完全杀灭货柜箱内红火蚁。其它投药浓度和熏蒸时间的组合均不能达到检疫除害的要求。In this paper,the suffocating efficacy of methyl bromide fumigation on the red imported fire ant was determined.When the density is 6.01 g/m3,12.01 g/m3,22.52 g/m3,25.53 g/m3,28.53 g/3,31.53 g/m3 and 37.54 g/m3 respectively in empty containers,25.53 g/m3,28.53 g/m3 and 31.53 g/m3 in full containers.Every container was fumed 2 h,4 h,6 h and 8 h respectively.The result indicates that methyl bromide 34.53 g/m3,4 h,28.53 g/m3,6 h and 22.52 g/m3,8 h can completely kill the red imported fire ant in empty containers.In full containers,31.53 g/m3,4 h,28.53 g/m3,6 h and 25.53 g/m3,8 h can effectively fumigate against the red imported fire ant.The other treatment can not meet the need of quarantine pesticides.
