目的通过现场调查,研究采用上海地方标准及国家标准的防鼠设施合格率与鼠密度的关系,为鼠类防治提供科学依据。方法在本区范围内抽取一定数量的农贸市场、饭店、食品加工、食品销售、超市、宾馆、学校、医院等进行防鼠设施合格情况及鼠征阳性情况调查。结果全区共调查773家单位,鼠征阳性为388家,单位阳性率为50.19%。调查房间3 172间,710间为鼠征阳性,房间阳性率为22.38%。应有防鼠设施处数1 011处,防鼠设施合格数740处,合格率为73.19%。其中符合上海地方标准防鼠设施合格率为67.26%,符合国家标准防鼠设施合格率为73.19%。二者之间χ2值为8.52,P<0.01,统计有极显著意义。不同场所防鼠设施合格率与鼠征阳性率呈负相关,r值为-0.925,P<0.001。结论本次调查结果表明上海地方标准的防鼠设施合格率严于国家标准;鼠征阳性率与防鼠设施合格率呈负相关关系。
Objective To investigate the relationship between pass rate and rodent density of rodent control facilities adopting Shanghai local standards and national standards through field investigation to provide scientific basis for rodent control. Methods A number of farmer’s markets, restaurants, food processing, food sales, supermarkets, hotels, schools and hospitals were selected to conduct a survey on the compliance of rodent prevention facilities and positive signs of rats in the area. Results A total of 773 units were investigated in the district, with 388 positives, the positive rate was 50.19%. Investigation of the room 3 172, 710 for the positive sign of the room, the positive rate of the room was 22.38%. There should be 1,111 rodent control facilities, rodent control facilities, the number of pass 740, with a pass rate of 73.19%. Which comply with the Shanghai local standard rodent control facilities pass rate of 67.26%, in line with the national standard rodent control facilities pass rate of 73.19%. Χ2 value between the two was 8.52, P <0.01, the statistics have very significant significance. The pass rate of rodent prevention facilities in different places was negatively correlated with the positive rate of rodents, r value was -0.925, P <0.001. Conclusion The survey results show that Shanghai local standard rodent control facilities qualified rate is higher than the national standard; the positive rate of rodents and rodent control facilities pass rate was negatively correlated.
