    摘要:

    以我国东部粘虫Mythimna separata(Walker)一代成虫迁飞期公主岭地面诱蛾量和同期降雨量的数据为预测因素,该世代成虫繁殖的危害种群在吉林省的发生程度和发生面积为预测目标,应用逐步回归法研究发生预测的数学模型。用Basic语言的计算机程序完成了计算、分析、筛选、组建多元回归方程式并与历年数据拟合的过程,提出了吉林省春季粘虫的发生预测模式。

    Abstract:

    The forecast elements were chosen from the data of field catches and rainfall of Gongzhuling,and the forecast targets were determined on the damage degrees and areas of outbreak of the yearly first generation adults and their next generation larvae of oriental armyworm,Mythimna separata(Walker),in Jilin province.The stepwise regression method was applied to study the forecast mathematic formula,and the computing,analysis,selecting,formation of polynomial regression equations and fitting of historical data were carry out by computer programs of Basic language.The forecast models of the spring generation oriental armyworm of Jilin province were put forward.
