摘  要:
根据湖北省主要产棉区 195 4~ 1997年棉铃虫第 3、4代发生程度的系统资料 ,应用Bayes判别分析原理 ,建立了棉铃虫发生程度的判别分析模型。通过对历史资料的回测及独立样本的预测 ,结果令人满意 ,从而为棉铃虫的长期预测预报提供了一个新的研究方法 ,亦可为其他虫害的预测预报提供借鉴

摘  要:
According to the data of the H. armigera (Hübner) generation degree in Hubei Province from 1954 to 1997, and applying the method of Bayes discrimination analysis, discriminant models of the H. armigera (Hübner) generation degree were established. Using models to simulate the historical records and to forecast independent samples got satisfactory results. In brief, this article provides a new forecasting method of H. armigera (Hübner) generation degree. It is also beneficial to other pests prediction.
