| Abstract: | The insect forecast is a difficult problem in plant protection. This paper has analysed the main factors which influence the insect density and made a new neural network predicative model. This method has a capacity for learning and can solve the forecasting problem which the traditional method could not. We have used this method to forecast the insect density in cotton field.The result shows that this method is better than other predicative methods and very useful in practice. |
