| 摘 要： | 本文应用逐步判别分析模型对第一代小地老虎为害程度进行了研究。结果表明：历史符合率达９１３％，将１９９０年作为独立样本进行试报，预测结果与实测相符，为农业害虫发生程度的预测预报提供了一种新的研究方法。

| Abstract: | From the application of the progressively discriminatory analysis models, the
authors deduce 4 discriminatory equations to forecast the damage level of the first generation
of Agrotis ypsilon (Rottemberg). The results of the pest data tested show that the fitting rate was
91.3%, and that the forecast conformed to the occurance of pest for 1990. This new method may
also be tried for the forecasting of other population dynamics of insect pests. |
