ABSTRACT
Objective To understand species, population density, and seasonality of rodents in Fangshan District of Beijing and provide the information for prevention and control of rodents and rodent-borne diseases. Methods The rodents were captured by using the trap at-night method in Mukezhai, Xianfenggu, Liushilu, Gushanzhai, Wanjingxiangou.The rodents pieces were identified and the density was calculated. Results Totally 4 665 traps were placed and 268 rodents were captured during 2016-2017.Among the seven identified species, the proportion of Apodemuspeninsulae was the highest (31.0%).The density of rodents was higher in primary forest area (7.29%) and edge area (6.10%) than in living area (2.94%)(P < 0.05).The density of rodents was 6.43% in 2016, and 4.44% in 2017(P < 0.05).The highest density (10.7%) was found in September. Conclusion The rodent species with highest density was Apodemuspeninsulae that can transmit Yersinia pestis.Comprehensive prevention measures should be taken to reduce the rodent density for controlling rodent-borne diseases.
