Abstract：Objective To analyze the population density and distribution characteristics of cockroaches in rehabilitation and convalescence centers and formulate precise prevention and control strategies.Methods Based on ecological niche differences,the monitoring area was divided into four types of habitats:vacant houses,nutrition buildings,convalescent rooms and family quarters.Sticky paper was randomly placed in cockroach houses at a ratio of 20％,and continuous monitoring was carried out for five months.All the collected specimens were taxonomically identified and statistical analysis were carried out.Results A total of 400 pieces of sticky paper were placed in the cockroach house(386 valid sticky papers were recovered),and 60 cockroaches were captured,with an overall density of 0.16 cockroaches per piece.The distribution of cockroaches reached its peak in December(with a density of 0.22 cockroaches per sheet),and the differences in the room invasion rate and the catch of cockroaches in each month were statistically significant(all P＜0.05).Among them,Blattella germanica was the dominant population(accounting for 90.0％),and its density shows a significant niche differentiation from that of Periplaneta americana(accounting for 10.0％).Conclusion The prevention and control of cockroaches in this rehabilitation and convalescence center should focus on strengthening environmental management during the high-incidence period from December to January of the following year,and optimizing the pest control plan based on the characteristics of the dominant population of B.germanica.At the same time,a continuous monitoring system should be established in combination with the business characteristics of convalescent institutions,and the cockroach prevention and control measures in rehabilitation and convalescent center should be constantly improved.This will effectively reduce the risk of vector transmission,improve the convalescent environment,and further ensure the health and safety of convalescent institutions and staff.
