Abstract：Objective To understand the three major vectors infestation in key types of industries(places)in Jiangxia District of Wuhan,so as to provide data basis for vector control in the region.Methods From August to November 2023,a field investigation was conducted to evaluate the current infestation status of rodent,fly and cockroach in 16 different units/places in 13 streets and towns in Jiangxia District of Wuhan.The rodent density were measured by rodent trace method and the density of flies and cockroaches were measured by visual observation method.Results The rate of rodent traces indoor was 6.21％,the percent of rooms that were correctly installed and used with rodent-proof facilities indoor was 89.17％,and the route index of rodent in outdoor areas was 0.73 traces per km.The percent of the rooms that were aggrieved by flies was 7.04％,the percent of rooms that were correctly installed and used with fly-proof facilities was 90.01％,and the rate of fly breeding sites was 2.81％;the infestation rate of adult and nymphae cockroach was 2.42％,the detection rate of cockroach egg was 2.80％,and the detection rate of cockroach trace was 2.04％.Conclusion The current status of three major vectors infestation in different types of industries(places)in Jiangxia District of Wuhan obtained in this investigation provides background data for the establishment of long-term management mechanism of vector control in the region in the future.
