摘要
研究了北太平洋海温与鲁西南第三代玉米螟发生程度、卵峰日的相关性，找出了优势相关区。利用优势相关区中相关最显著的海温因子建立了预报模式，预报时效可提前２０ ｄ 以上。经检验。
How severely Generation 3 (G3) maize borer breaks out in Southwest Shandong and when it lays the most eggs are related to sea surface temperature (SST) of the North Pacific. Predominant correlative zones are found and the SST in the zones is used to establish a forecasting model for the borers outbreak degree and egg peak date. Results show that the model is applicable and can make a forecast 20 days ahead of the borers breaking out.
