目的掌握中蒙边防部队营区鼠种与密度,为鼠类防治提供科学依据。方法采用目测法与鼠夹法。结果经鉴定有2个鼠种,分别为灰苍鼠、小家鼠,分别占鼠数的75.15%、24.85%,鼠密度下降至5.81%,密度下降率为93.16%。结论该边防连队营区虽然位于中蒙边境贸易口岸附近,人车来往频繁,物流量大,但营区鼠类仅2种,鼠夹灭鼠法效果明显,同时要考虑综合方法进行防治,加强防鼠设施建设尤为重要。 Objective To understand the species and density of the battalion of the Sino-Mongolian border troops in order to provide a scientific basis for the prevention and control of rodents. Methods Visual method and mouse clamp method. Results Two species of mice were identified as gray and white mice, accounting for 75.15% and 24.85% of the total. The density of rats decreased to 5.81%, and the density decreased to 93.16%. Conclusions Although the border company’s camp area is located near the border trade port between China and Mongolia, there are frequent traffic and traffic between the vehicles and vehicles, but there are only two kinds of rodents in the battalion area. The effect of rat-trap rodent control is obvious. At the same time, comprehensive methods should be taken to prevent and control rodents Construction is particularly important.
