本文用Ｃｏｂｂ－Ｄｏｕｇｌａｓｓ（库伯—道格拉斯）函数模型对越冬代玉米螟的产卵期进行了分析。结果表明：ｙ＝２８１３１１９８５．５ｘ－３．６９６８１ｘ－０．７５２８２ｘ－０．１８８４３可以提供较多的内涵专业信息，并可对越冬代玉米螟的产卵期进行预测
In this paper, we used the Cobb-Douglass function model to analyze the spawning period of overwintering generations of Ostrinia furnacalis. The results showed that: y = 281311985.5x-3.69681x-0.75282x-0.18843 could provide more connotative professional information and could forecast the spawning period of overwintering generation of Ostrinia furnacalis
