摘　　要：目的为了解某地区动车组列车蟑螂密度现状及季节分布规律,为蟑螂防治提供科学依据.方法选取400节50组列车,每节车厢采用标准化作业方法进行防治和采用粘蟑法进行调查蟑螂侵害情况.结果动车组列车蟑螂种类主要为德国小蠊;2021年、2022年最高的车型均为外区2A(2.38、0.43只/节);2021年、2022年检出部位占比最高为座椅33.74%和茶炉柜39.41%;不同车厢之间侵害频次没有差异;1季度为蟑螂侵害高峰期.结论2022年蟑螂密度低于2021年.只有进行综合治理,才能长期有效地控制蟑螂密度.To investigate the current density and seasonal distribution pattern of cockroaches in CRH trains,and provide scientific basis for cockroach control and prevention.Methods 400 trains were selected,and standardized operation methods were used to prevent and control cockroaches in each compartment,while sticky traps were used to investigate the intensity of cockroach infestation.Results The cockroaches in CRH trains were mostly Blattella germanica.The highest density of cockroaches in 2021 and 2022 was found in the external type 2A trains(2.38 and 0.43 cockroaches per compartment,respectively).The highest detection rate for cockroach infestation in 2021 and 2022 was in the seats(33.74%)and the tea cabinet(39.41%).There was no difference in the frequency of infestation between different train compartments.The first quarter of the two years was the peak period for cockroach infestation.Conclusion The density of cockroaches in 2022 is lower than in 2021.Only integrated management can achieve the goal of long-term effective control.
