目的掌握台州市鼠类种群、密度和季节消长情况,为灭鼠巩固工作提供依据。方法每个县(市、区)随机选择居民区、重点单位和城中村为监测点,采用夹夜法捕鼠并计算鼠密度。结果台州市以褐家鼠为优势鼠种,2011—2014年月平均鼠密度波动范围为0.21%~0.58%,4—5月和8—10月出现高峰;年平均鼠密度为0.37%~0.40%;重点单位和城中村年平均鼠密度明显高于居民区(P<0.05)。结论春秋季是突击灭鼠的最佳时机,褐家鼠为优势鼠种,重点单位和城中村是巩固灭鼠工作的重要监测点。
Objective To understand the population, density and seasonal fluctuation of rodents in Taizhou and provide the basis for the consolidation of rodent control. Methods Each county (city, district) randomly selected residential areas, key units and the village in the city as the monitoring point. Results Rattus norvegicus was the dominant species in Taizhou. The monthly average density of rodent densities fluctuated from 0.21% to 0. 58% in 2011-2014, and peaked from April to May and from August to October. The annual mean rodent density was 0.37% -0.40 %; The annual average density of rodents in key units and urban villages was significantly higher than that in residential areas (P <0.05). Conclusion Spring and autumn are the best time to assault rodent. Rattus norvegicus is the dominant species. The key units and Chengzhongcun are important monitoring points to consolidate the anti-rodent work.
