Analysis on the rodents density monitoring data in Fangshan District of Beijing, 2016-2017

ObjectiveTo 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.

MethodsThe 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.

ResultsTotally 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.

ConclusionThe 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.
