  3. The transformants of strain ybt - 1535 displayed significantly higher toxicity against s. exigua than strain ybt - 1535 ( at least 8 times ), but the toxicity against heliothis armigera and plutella xylostella changed little. for the strain ybt - 1520, the effect was not the same as strain ybt - 1535

    結果菌株ybt - 1535的轉化子對甜菜夜蛾的毒力有非常顯著的提高（ 8倍以上） ，對棉鈴蟲和小菜蛾的毒力影響不大，轉化子的綜合毒力高於ybt - 1535 。
  4. Thus, in the last of the thesis, we construct a artificial neural network model based on the improved bp algorithm to predict the plant diseases and insect pests of cotton heliothis armigera. the simulation used matlab to the artifical neural network indicated that the prediction is correct and ( completely

    因此，在文章的最後，構建了一個基於本文提出的改進的bp演算法的神經網路模型來預測棉花棉鈴蟲病蟲害，通過對此神經網路的matlab模擬表明，預測準確，達到了很好的效果。
