Abstract: The meteorological conditions for the occurrence of corn borer were divided into 5 grades.It was supposed that each meteorological factor was linear with the occurrence of corn borer and all of factors were addable.The predict equation of meteorological suitability grade for the occurrence of the first generation of corn borer in Jilin Province was constructed.The equation was validated by the historic data of meteorology and occurrence of the corn borer in recent 26 years.The meteorological suitability grade for the occurrence of the corn borer in 2007 was predicted.The results showed that the model could be used for monitoring and prediction of meteorological suitability grade for the occurrence of corn borer.

Key words: Prediction of meteorological suitability grades, Prediction of meteorological suitability grades, Corn borer, Jilin Province
