基于通用的置信区间型序贯抽样方法，提出了两种新的序贯抽样模型：（１）用两个可靠性指标来估计判断调查虫口是否达到一个防治指标。（２）用一个可靠性指标来判断调查虫口是否达到经济阈值和经济损失水平两个防治指标，将经济核算与防治决策直接结合使用
Based on the common confidence interval sequential sampling method, two new sequential sampling models are proposed: (1) Two reliability indexes are used to estimate whether the detection of the population of insects reaches a control index. (2) Using a reliability index to determine whether the survey population has reached the economic threshold and the economic loss level two prevention and control indicators, the economic accounting and prevention and control decisions directly with the use of
