观察以生态学方法为主的综合措施防制城镇居民区家栖鼠的效果

Observation on Prevention and Control for Houserats in Urban Residential Area Taking synthetic Ecological Measures

目的 :比较生态学方法的防制与单纯药物防制城镇居民区家栖鼠的效果。方法 :在 1995～ 1996年试验的基础上 ,按照试验的要求继续观察其效果 ,鼠密度监测由每月 1次改为每季度监测 1次。结果 :生态防制区家鼠密度明显下降 ,从试验的第 5个月直至结束后的 4年间鼠密度一直巩固在国家标准 3 %以下 ;药物区仍然是投药后的 1～ 2个月内鼠密度有所下降 ,其他月份均在 6%左右 ,有时高达 10 %以上 ;空白区一直在 10 %左右 ,最高时可达 12 %～ 14 %。结论 :从试验后连续 4年的观察结果表明 。

Objective:To compare the offect of preventing and controlling houserats by ecological method or by drugs only. Methods:On the basis of the experiment from 1995 to 1996, To observe the effect,monitoring the houserat density every season. Results:In ecological prevention area, the houserats density was reduced apparently to 3% (state standard).and it keeps the same level for four years: In the area applying drugs only the houserat density was reduced for the first two months,in the months later,it rised to 6%, sometimes even to 10%; in the bland area,the rat density may reach 12%-14%. Conclusion:With four year's observation, the effect of taking ecological measures to prevent and control houserats in Urban residential area was better and longer than that of using drugs only.
