Transgenic crops expressing Bacillus thuringiensis Berliner (Bt) have been cultivated throughout the world as a great technological tool for developing integrated pest management. We hypothesized that artificial landscapes containing Bt and non-Bt cotton plants (Gossypium hirsutum L., Malvaceae) at small scales could influence dispersal by ballooning of Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae). We also simulated how ballooning dispersal combined with walking movement could impact resistance evolution in various scenarios of plant mixtures involving non-Bt and Bt cotton plants with high-dose and low-dose events. The ballooning frequency of Cry1F-resistant larvae in a treatment with non-Bt cotton as a natal plant and Bt cotton in adjacent sites was two-fold lower compared to when Bt cotton was the natal plant and non-Bt cotton was in the adjacent sites. Our model results suggested that the higher rate of walking movement associated with ballooning promoted faster resistance evolution in low-dose events, and contamination of Bt cotton fields with non-Bt cotton plants in a high-dose event showed the longest time to resistance. Therefore, a high rate of walking movement associated with ballooning negatively impacted the time for resistance to evolve in low-dose events.

草地夜蛾在 Bt 和非 Bt 棉花植物混合物中膨胀和步行扩散的贝叶斯推理的进化过程建模

表达苏云金芽孢杆菌柏林 (Bt) 的转基因作物已在世界各地种植，作为开发综合虫害管理的重要技术工具。我们假设包含小规模Bt 和非 Bt 棉花植物（Gossypium hirsutum L.，锦葵科）的人工景观可能通过草地贪夜蛾的膨胀影响扩散（JE 史密斯）（鳞翅目：夜蛾科）。我们还模拟了气球扩散与步行运动相结合如何在涉及非 Bt 和 Bt 棉花植物高剂量和低剂量事件的各种植物混合物场景中影响抗性进化。用非 Bt 棉花作为出生植物和相邻地点的 Bt 棉花处理 Cry1F 抗性幼虫的气球频率比 Bt 棉花作为出生植物和非 Bt 棉花在相邻地点时低两倍. 我们的模型结果表明，在低剂量事件中，与气球相关的较高步行运动速率促进了更快的抗性演化，并且在高剂量事件中，非 Bt 棉花植物对 Bt 棉田的污染显示出最长的抗性时间。所以，
