By investigation on the relationship between period, quantity, extend of Ostrinia furnacalis emergence and meteorological factors in Qiqihaer, this paper analyzes the factors which effect on period, quantity, extend of Ostrinia furnacalis about annual wave. The beginning time of Ostrinia furnacalis pupae emergence depends on average temperature in May and June, weather conditions in July decide whether Ostrinia furnacalis pupae finish ahead of time; the beginning time of eclosion is decided by average lowest temperature and precipitation in May and June, and the end time of eclosion is decided by average lowest temperature in June and July, meantime, the length of time of Ostrinia furnacalis eclosion and time of grub emergence influence on the extent of Ostrinia furnacalis. An important condition of a great emergence of Ostrinia furnacalis is that how temperature matchs humidity, which substantially result in reduction of maize output.Based on above analysis, using statistical method such as similar regression step by step , the quantitative model and qualitative model for date quantity and extent of Ostrinia furnacalis forecasting were developed. By research the relationship among date, quantity and extent of Ostrinia furnacalis and yield of Maize, the estimated model of loss that yield of Maize was effected by date, quantity and extent of Ostrinia furnacalis was developed. The forecasting result was satisfactory after predicting. In the end sofeware was developed with VB . we can inquire the charicite and regular of Ostrinia furnacalis , input, modify and inquire factors of Ostrinia furnacalis, forcast and relevant prevention and cure occurring and growing of Ostrinia furnacalis. The software can be directly installed at every computer , it is easy to use and upgrade.
