蒙自市农村农户养猫降低鼠密度的效果观察

Observation on effects of reducing rodent density by raising cats in rural areas of Mengzi City

目的了解蒙自市农村农户养猫降低鼠密度的效果,找出农村农户养猫和不养猫自然村鼠密度的变化情况。方法分层随机抽取蒙自市辖区内山区和坝区乡镇各1个,在抽到的乡镇中再随机抽取不养猫及养猫农户为25%、50%、74%、100%的自然村进行鼠密度调查。结果农村农户不养猫与不同养猫比例自然村的鼠密度无关联(P>0.05);春季室内外鼠密度高于秋季室内外鼠密度(P<0.05)。结论农村农户不养猫及养猫多少对鼠密度没有影响。

Objective To learn about the effects of reducing rodent density by raising cats,and find the difference between villages which raise and don ＇t raise cats.Methods Two towns were selected respectively in mountainous areas and non-mountainous areas of Mengzi City by stratified random sampling method.In chosen towns,the villages with proportion of raising cats as 0%,25%,50%,74% and 100% were randomly selected to detect the rodent density.Results There was no relationship between cats raising and rodent density（P 0.05）;The rodent density inside or outside room in Spring was higher than that in Autumn（P 0.05）.Conclusions There was no relationship between cats raising and rodent density.
