摘　　要：目的分析动车组列车的特殊内部环境特点,结合动车蜚蠊的生活习性,为提供专门的动车蜚蠊防治方法提供科学依据。方法对某铁路局的动车进行全面摸底调查〔17组车体,共计230个车厢(包括驾驶员室)〕,监测动车车厢内蜚蠊密度,运用SPSS统计软件,找出动车灭蠊的关键控制点进行灭蠊,总结动车灭蠊经验。结果动车组列车蜚蠊成若虫的侵害率为19.13%,吧台、保鲜柜、座位下等部位的蜚蠊分布最为密集。选择灭蟑胶饵(每片含1%的氟虫胺)进行试验,最终监测结果蜚蠊平均密度均<1只/厢。结论掌握动车蜚蠊的生活习性和分布特点,探索出适合动车组列车的灭蠊方法。试验结果证明该方法与原灭蠊方法(喷洒法)效果比较差异有统计学意义。Objective The characteristics of the internal environment of CRH（China Railway High-Speed） trains were analyzed to provide the basis for development of the specialized roach control measure for CRH trains based on the living habits of cockroaches therein.Methods A thorough investigation into the CRH trains of a certain railway bureau was conducted（17 carriages,230 compartments including the driver＇s room） to monitor the cockroach density in the trains.SPSS was used to identify the critical control points for elimination of cockroaches for the CRH trains.Results The infestation rate of adult and nymphal cockroaches in the CRH trains was 19.13%.The highest density of cockroaches was found at the buffet,fresh cabinets and under the seats.Gel baits for cockroach（containing 1% sulfluramid each tablet） were applied for testing;finally,the average cockroach density was less than of one per compartment.Conclusion The cockroach control method suitable for CRH trains was developed based on the living habits and distribution patterns of cockroaches.Experimental results showed significant difference in the control effect between the developed method and the original method（insecticide residual spraying）.
