| 摘 要： | 用概率理论指出集团母蛾检验方法只是在总体病蛾率为０．５％以下，且样本有毒集团数（Ｓ）一般小于１３时才成立，当５大于１３时，某些有毒集团中含有２只病蛾的概率是较大的。针对不同总体，找出了Ｓ与有毒蛾数（ｄ）之间的关系，既依赖于总体大小，又依赖于总体病蛾率。其简化公式为ｄ＝［１．０７Ｓ＋０．０７］。

| Abstract: | According to the theory of probability , it is proved that the inspection of populationfemale mots can be carried out only under the conditions that the percent of a total pe-brinemoth is lower than 0.5%and the number of pebrine population in a samlpe (S) isless than 13. When the S is more than 13, the propability that there are 2 pebrine mothsin apopulation is high. According to the methed of probability statistics, the relation-ship between the S and the number of pebrine moth is found.It depends on not only the number of a total but also the percent of pebrine moths in a total.The formula of their relationship is: d=[1.07S+0. 07]. |
