In this review, we evaluate the intentional mixing or blending of insecticidal seed with refuge seed for managing resistance by insects to insecticidal corn (Zea mays). We first describe the pest biology and farming practices that will contribute to weighing trade-offs between using block refuges and blended refuges. Case studies are presented to demonstrate how the trade-offs will differ in different systems. We compare biological aspects of several abstract models to guide the reader through the history of modeling, which has played a key role in the promotion or denigration of blending in various scientific debates about insect resistance management for insecticidal crops. We conclude that the use of blended refuge should be considered on a case-by-case basis after evaluation of insect biology, environment, and farmer behavior. For Diabrotica virgifera virgifera, Ostrinia nubilalis, and Helicoverpa zea in the United States, blended refuge provides similar, if not longer, delays in the evolution of resistance compared to separate block refuges.
在本综述中，我们评估了将杀虫种子与庇护所种子有意混合或掺和，以应对昆虫对杀虫玉米（玉米）产生抗性的情况。我们首先描述害虫生物学和种植实践，这些有助于权衡使用块状庇护所和混合庇护所之间的利弊。通过案例研究来说明在不同系统中利弊将如何不同。我们比较了几个抽象模型的生物学方面，以引导读者了解建模的历史，建模在关于杀虫作物抗虫管理的各种科学辩论中，对混合种植的推广或诋毁起到了关键作用。我们得出结论，在评估昆虫生物学、环境和农民行为之后，应逐案考虑使用混合庇护所。对于美国的玉米根萤叶甲、欧洲玉米螟和棉铃虫，与单独的块状庇护所相比，混合庇护所即使不能更长时间，也能提供类似的抗性进化延迟。
