Abstract:

Objective To investigate the feasibility and application effect of powder trace method in outdoor surveillance of rodent density in urban communities. Methods The powder trace method and rodent trace method were used simultaneously to monitor the outdoor rodent densities in 10 communities of Huangshi, China, and the surveillance results were subjected to statistical analysis. Results The powder trace method showed that the valid powder rate was 89.11% and the positive rate of rodent traces was 6.41%. The rodent trace method showed that the path index was 20.08 places/km. The correlation analysis revealed no significant correlation between the surveillance results of the two methods (r=0.407, P=0.243). Conclusion The powder trace method can be applied for outdoor surveillance of rodent density in urban communities when the weather is favorable.

摘要：

目的 探讨粉迹法应用于城市社区室外鼠密度监测的可行性和应用效果。方法 同时采用粉迹法和鼠迹法,对黄石市10个社区室外鼠密度进行监测,对监测结果进行统计分析。结果 10个社区室外鼠密度监测,粉迹法监测有效粉块率为89.11%,鼠迹阳性率为6.41%;鼠迹法监测结果,路径指数为20.08处/km。将两种方法的监测结果进行相关性分析,差异无统计学意义(r=0.407,P=0.243)。结论 选择适宜的天气,粉迹法可应用于城市社区室外鼠密度监测。
