Research on cockroach killing method on CRH trains

目的探索动车组列车杀灭蟑螂的有效方法。方法采取毒饵、胶饵、毒饵+胶饵3种施药方法进行杀灭效果对比观察。结果 3种施药方法施药3 d时杀灭率分别为89.10%、52.65%and 89.52%,经统计学检验具有显著性差异。结论联合法适合于蟑螂密度较高时的大面积快速杀灭,蟑螂密度较低时仅采用胶饵法即可达到良好的杀灭效果。

Objective To explore the killing cockroach effective method on CRH trains. Methods Taking the bait powder method,gel bait,bait powder gel bait combined method to observe the effect of sterilization. Results Three kinds of application methods of spraying 3 day killing rate were 89.10% ,52.65% and 89.52% respectively, which the statistics was a very significant difference. Conclusion Bait powder combined with gel bait is suitable for high density of cockroaches at large area. When cockroach density is low, gel bait can achieve long term efficacy.
