使用热烟雾技术对旅客列车这一密闭环境进行灭蟑效果试验,空调与非空调旅客列车热烟雾灭蟑,2h后的蟑螂平均杀灭率分别为95.8％和92.1％,二者无显著性差异(P>0.05);30d后蟑螂平均杀灭率分别下降为80.0％和78.8％,30d后,各车厢蟑螂密度有所回升。建议定期进行监测,再次杀虫以保证蟑螂低密度。
Using hot smog technology to test the cockroach killing effect of passenger trains in a closed environment, the average killing rates of cockroaches after 2 hours were 95.8% and 92.1% respectively for air-conditioning and non-air-conditioned passenger train hot fogging. There was no significant difference between the two (P> 0.05). After 30 days, the average killing rate of cockroaches dropped to 80.0% and 78.8%, respectively. After 30 days, the cockroach density in each cabbage increased. It is recommended to monitor regularly to kill insects again to ensure low density of cockroaches.
