| Abstract: | The Back Propagation algorithm of the neural network was used to analyse the data of field occurrence of rice planthoppers, the temperature difference in early, middle and late April, May and June, precipitation and relative humidity in the infested areas of Sichuan province. Based on such an analysis, a trial forecast was made of the occurrence of the pest and gave relatively satisfactory result. |
