目的了解建筑情况对鼠类种群数量的影响。方法在辖区内随机抽取建筑为砖混结构且地面硬化等居住(生活)条件较好和建筑为土木结构且泥土地面等居住(生活)条件较差居民区进行鼠密度调查。结果总鼠密度为2.5%(χ2=0.4,P>0.05),差异无统计学意义;室内鼠密度1.7%(χ2=1.6,P>0.05),差异无统计学意义;室外(农耕地)鼠密度4.3%(χ2=3.94,P<0.05),差异有统计学意义;鼠体染蚤率55.0%,蚤指数为7.8,为印鼠客蚤;家鼠体表均有不同程度的染蚤,褐家鼠染蚤率高(100.0%),蚤指数高(17.0);鼠种间染蚤率差异无统计学意义(χ2=0.23,P>0.05)。结论蒙自市农村居住(生活)条件较差居民区室外(农耕地)鼠密度比居住(生活)条件较好的居民区高。
Objective To understand the impact of building conditions on the number of rodents. Methods Randomly surveyed the density of residential areas with poor living (living) conditions such as brick-concrete structure, hardened ground and other living (living) conditions, and civil engineering structures and soil surfaces. Results The total rat density was 2.5% (χ2 = 0.4, P> 0.05), but the difference was not statistically significant. The indoor rat density was 1.7% (χ2 = 1.6, P> 0.05) The density was 4.3% (χ2 = 3.94, P <0.05), the difference was statistically significant. The flea flea rate was 55.0% and flea index was 7.8, Rattus norvegicus had a high rate of flea infection (100.0%) and a high flea index (17.0). There was no significant difference in the rate of flea infection between species (χ2 = 0.23, P> 0.05). Conclusion Residents living in rural areas of Mengzi have poorer conditions than those in residential areas with better densities than living (living) conditions.
