动车组列车蟑螂种群分布及生态习性的研究

Investigation of EMU cockroach population distribution and ecological habits

目的摸清动车组列车蟑螂种群分布及生态习性,为动车组列车蟑螂防治提供科学依据。方法蟑螂屋粘捕法,跟踪观察蟑螂活动情况。结果动车组列车蟑螂种类主要为德国小蠊,蟑螂密度指数:废物箱后>饮水机后>配电室>吧台下>备品间>卫生间>储藏间;施药90 cm以下高度盗食率为81.11%。结论动车组列车蟑螂主要分布于废物箱后、饮水机后、配电室等部位,90 cm以下高度是蟑螂主要栖息及活动场所;其活动规律与其他场所蟑螂基本相同。蟑螂主要是餐车出售食品上货时带入,旅客行包带入,列车整备人员带入,乘务人员带入4种途径。

Objective To find out the population distribution and habits of EMU train cockroaches, and provide scientific basis for preventing and controlling the EMU train cockroaches. Methods House sticky cockroach recap- ture method, tracking and observing the activities of the cockroaches. Results The cockroaches on the EMU main mostly were German cockroach. Cockroaches density index ： after the waste box 〉 after water machine 〉 distribution room 〉 under bar counter 〉 spare parts storage 〉 bathroom 〉 storage room ; treatment medicine under 90 em, the per- centage of eating by stealth was 81.11%. Conclusion EMU cockroaches mainly distributed after the waste box, the water machine, the power distribution room and so on, the main habitat venues of cockroaches where height is less than 90 cm. The activity patterns are basically the same with the cockroaches in other places. Boarding way of the cockroaches are mainly the following four kinds：the sale of food on the dining car cargo, passengers line package, train preparedness personnel, crew members.
