目的:掌握宁波市农村地区鼠形动物种群结构的动态变化和季节消长规律。方法:整理1996-2011年间鼠情监测的资料,进行分析。结果:16年来共捕获6个种的2 390只鼠形动物,其中褐家鼠为优势种,小家鼠和臭鼩鼱为常见种。农村野栖鼠种主要为褐家鼠。农村地区鼠形动物种群密度在3～4月和9～10月呈现两次高峰。结论:在每年的春、秋两季,选择杀灭效果较好的毒饵,采用合理的投饵方式,分别开展一次主要针对褐家鼠的灭鼠活动,以降低鼠类的密度。
Objective: To master the dynamic changes of population structure of rats in the rural area of Ningbo City and the seasonal fluctuation pattern. Methods: The data of rat monitoring during 1996-2011 were collected and analyzed. Results: A total of 2 390 mammals of 6 species were captured over the past 16 years, of which Rattus norvegicus was the dominant species and Mus musculus and Sesamum were common species. Rodent species in rural areas mainly for Rattus norvegicus. In rural areas, the density of mouse-shaped animals in April and April and September to October showed two peaks. Conclusion: In the spring and autumn of each year, poison bait with good killing effect was chosen. Rodent activities mainly aimed at Rattus norvegicus were carried out by using reasonable bait method to reduce the density of mice.
