我们使用一个监管模型，在两个害虫的抗性演变杀虫Bt棉和拟除虫菊酯（一种传统的杀虫剂），以检查非Bt棉（避难所）种植的要求，旨在管理Bt抗性演变在中南部。我们的分析表明，减少避难所的要求将提高生产者的盈利能力，喷洒避难所比未喷洒避难所更具成本效益，生产者将获得略高的回报动态相对于静态避难政策。其中一种害虫对拟除虫菊酯的敏感性是一种可再生资源，与Bt棉花中拟除虫菊酯使用相关的毒素混合效应是中南避难政策的重要考虑因素。
We use a regulatory model with resistance evolution in two pests to insecticidal Bt cotton and pyrethroids (a conventional insecticide) to examine non-Bt cotton (refuge) planting requirements designed to manage Bt-resistance evolution in the midsouth. Our analysis suggests that reduced refuge requirements would enhance producer profitability, sprayed refugia are more cost effective than unsprayed refugia, and producers would receive slightly higher returns under dynamic relative to static refuge policies. Pyrethroid susceptibility in one of the pests was a renewable resource, and toxin-mixture effects associated with pyrethroid use in Bt cotton were important considerations for midsouth refuge policies.
