2010年泰安市鼠密度监测结果分析

Monitor of rodent density in Tai'an city in 2010

目的掌握泰安市鼠类种群构成、季节消长和不同生境鼠密度情况,为制定鼠类防控方案提供科学依据。方法随机抽取特殊行业、自然村和居民区各1处作为监测点,采用夹夜法进行鼠类密度监测。结果 2010年共捕获鼠类4种103只,平均鼠密度为1.9%。其中,褐家鼠为优势种群,密度达1.1%,占捕鼠总数的58%。鼠密度消长呈单峰型曲线,高峰值出现在4月份。不同生境鼠密度季节消长曲线不同。特殊行业鼠密度最高,达2.6%。结论 2010年鼠密度水平较高,褐家鼠是重点防控鼠种。建议根据它们的孳生、栖息习性及季节消长特点,采取综合防治措施,并加强对鼠类及其传播疾病的长期监测、预警和控制对策的研究。

Objective To grasp the population composition and its seasonal fluctuation of rodent in Tai＇an city,and provide scientific basis for developing mosquito control program.Methods Night trap method was used to monitor the rodent density.Results A total of 103 rodent were captured,with the average rodent density of 1.9%.Of which,the dominant specie was Rattus norvegicus（58%）,and the density was 1.1%.The fluctuations of the rodent density followed a single-peaked curve,the peak value appearing in April.It was different from the seasonal fluctuations of the rodent density in different habitats.The rodent density in special industry was very high（2.6%）.Conclusion The level of rodent density is high,and the main control targets are Rattus norvegicus in Tai＇an city,so it should take the integrated measures to reduce the rodent density according to the characteristics of its breeding,habits and seasonal dynamics,and strengthen the surveillance,warning and measures of rodents and its diseases.
