目的了解马鞍山市鼠类种群构成、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。方法随机抽取农村自然村、城镇居民区2种类型监测点各1个,餐饮业2个,采用夹夜法进行鼠密度监测。结果 2010-2012年共捕获鼠类42只,平均鼠密度为0.20%,小家鼠(52.38%)与褐家鼠(47.62%)为城市优势种,不同生境鼠密度居民区﹥餐饮业﹥自然村;全年有两个密度高峰期即4月(0.39%)和6月(0.5%),5月、7-10月一直维持低密度,平均鼠密度与月平均气温呈现极显著正相关关系(r=0.67,P<0.01)。结论基本掌握了马鞍山市鼠种群构成及消长规律,建议根据鼠类栖息习性及季节消长特点,采取综合性防治措施。
Objective To understand the composition, seasonal fluctuation and density of rodents in different habitats in Ma’anshan, and provide a scientific basis for the development of rodent prevention and control programs. Methods A total of 2 types of monitoring sites in rural natural villages and urban residential areas were randomly selected and two in the catering industry were randomly selected. Results A total of 42 rodents were captured from 2010 to 2012, with an average rat density of 0.20%. Mus musculus (52.38%) and Rattus norvegicus (47.62%) were dominant species in urban areas. There were two density peaks (April (0.39%) and June (0.5%)) throughout the year. Low density was maintained in May and July-October. There was a significant positive correlation between mean rat density and monthly mean temperature ( r = 0.67, P <0.01). Conclusion The composition and growth and decline pattern of rat population in Ma’anshan are basically mastered. It is suggested that comprehensive prevention and control measures should be taken according to the characteristics of habitat and seasonal growth and decline of rodents.
