为了提高特殊环境灭鼠效果估计的准确性,深入认识各种灭效评定方法的性能和特点,在一次现场灭鼠试验中,对常用的家鼠密度调查方法——食饵法和迹粉法进行了考察。相关分析显示,两法所测得的鼠密指标之间不呈相关,因而不能相互代替:迹粉法本身的计点和计量指标之间呈高度相关,因而在用迹粉法估计灭效时将计量指标分得过细似无必要。灵敏度分析显示迹粉法优于食饵法,稳定性分析显示食饵法优于迹粉法,说明两法在评定同一次灭鼠效果中可以取长补短,互为补充,以提高对灭效估计的准确性,这在评价特殊环境的灭鼠效果中很有意义。
In order to improve the accuracy of estimation of rodent control in special environment and to deeply understand the performance and characteristics of various methods of evaluation of culling, in a field rodent control experiment, The inspection. Correlation analysis showed that the two methods did not correlate with each other and therefore could not replace each other: the dot count method itself has a high degree of correlation with the measurement index, It is unnecessary to divide the measurement index too carefully. Sensitivity analysis showed that the method of flour was superior to the bait method, and the stability analysis showed that the bait method was superior to the method of streak method, indicating that the two methods can complement each other in assessing the same deratting effect and complement each other to improve the accuracy of the estimation. , Which makes sense in assessing the effects of rodent control in special environments.
