| 摘 要： | 本文利用福建省永安市１９７８－１９８８年诱虫灯下二化螟蛾发生期资料和气象资料，通过影响因子与预测对象的相关分析来选择初选因子．再应用逐步判别分析方法建立第一代二化螟蛾发生期的预测模型。经对历史资料的回报检验，该模型的判别率达９０．１－１００％；经１９８９和１９９０年实报，预报等级符合实际发生等级。

| Abstract: | The previous data on the moth occurrence date of rice stem borer[Chilosuppressalis(Walker)]under the forecasting light and the historical records ofmeteorological phenomena over the past successive year of 1978- 1988 in Yongan city wereused to select the preliminary factors according to the correlative analysis.The forecastingmodels of occurrence date for the first generation moth were established on the basis ofstepwise discriminatory analysis.The discrimination rate in the forecasting models reached90.1-100%through examination of the former data.The practical use of the models during1989- 1990 had verified the consistency between forecasting grades and actual occurrencegrades. |
