测试居民区住宅外鼠密度的可行性研究

目的塑料地板胶制鼠迹板测试居民区住宅外鼠密度可行性。方法在居民区住宅外分3种生境进行试验，次日观察鼠迹板阳性率、损坏率和丢失率。结果普通地面平均损坏率为49．1％，楼梯、外长廊为16．3％，楼顶、露台损坏率为10．0％。经秩和检验，普通地面与另外2种生境之间的鼠迹板损坏差别有统计学意义（U=5．72和6．37，P〈0．001），而楼梯、外长廊与楼顶、露台之间比较鼠迹板损坏差别无统计学意义（U=0．97，P〉0．05）。结论鼠迹板适合监测鼠情，测试居民区外环境鼠密度有待研究。

Feasibility study on testing rat density in residential districts

Objective To study the feasibility on the rat density tested by the plastic rat trace board in residential districts. Methods Residential area which was divided into three environments was tested, observed by the rat trace board of positive rate, loss rate and lost rate in the following day. Results The average loss rate at common ground was 49. 1% , which was 16.3% at stair and verandah, 10. 0% at the roof and gazebo. By rank-sum test, the loss of rat trace board between the common ground and another environments was remarkable （ U = 5.72 and 6. 37, P 〈 0. 001 ）, while was not remarkable between the other two environments （ U = 0. 97,P 〉 0. 05 ）. Conclusion The rat trace board method is reasonable for monitoring the rat condition, but the method of testing the rat density in residential districts is to be studied.
