白僵菌防治烟田小地老虎的仿真研究

以烟田生态系统的关键物种小地老虎为中心,对于使用白僵菌防治小地老虎这一害虫生物防治过程进行仿真。使用Netlogo仿真工具进行实验,设置不同剂量的白僵菌反复运行模型。通过分析实验数据,研究一定面积的烟田中白僵菌的用量与烟株受损率以及小地老虎存活率之间的关系。实验结果表明,在大约为2500烟株的烟田中,烟株受损率、小地老虎存活率随投放白僵菌粉的数量的增加而下降,下降趋势从一开始的剧烈下降到最后趋势平缓。

Simulation on Control of Agrotis Ypsilon Rottemberg in Tobacco Field with Beauveria Bassiana

The experiment uses Agrotis ypsilon Rottemberg and Beauveria bassiana as objects to simulate the biological control process of using Beauveria bassiana to control Agrotis ypsilon Rottemberg .The experiment uses Netlogo as a tool to study the relationship between the amount of Beauveria bassiana used in certain area of tobacco field and tobacco damage rate and black cutworm survival rate through setting different amount of Beauveria bassiana and analyzing the experiment data acquired. The results showed that...
