[目的 ]探讨环氧乙烷混合制剂在集装箱内熏蒸对德国小蠊、黑皮蠹的杀灭效果。 [方法 ] 2 0 0 1年 5月采用现场试验方法分别在试验组和对照组集装箱内不同位置放置等量试虫 ,按 1 0 0g/m3施放 1 0 %、2 0 %的环氧乙烷杀菌气 ,2 4h后分别观察试虫死亡数并计算死亡率。 [结果 ]在环境温度为 (33± 4)℃、相对湿度为 60 %～ 80 %时 ,对德国小蠊、黑皮蠹的杀灭率为 1 0 0 %。 [结论 ] 1 0 %、2 0 %环氧乙烷杀菌气可用于集装箱、密闭大型容器的害虫防制 [Objective] To investigate the killing effect of ethylene oxide mixture on German cockroach and black beetle in fumigation in container. [Method] In May 2001, field test was used to place the same amount of test insects in different positions in the container of the test group and the control group, respectively, and 10% and 20% of ethylene oxide Bactericidal gas, 24 h after the observation worm mortality were calculated and mortality. [Result] When the ambient temperature was (33 ± 4) ℃ and the relative humidity was 60% ~ 80%, the killing rate against German cockroach and black beetle was 100%. [Conclusion] 10%, 20% ethylene oxide sterilization gas can be used in container, closed pest control of large containers
