Abstract：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.
