Helicoverpa zea is a destructive pest and target of maize and cotton expressing Cry and Vip3Aa proteins in North America. The efficacy of Cry proteins against H. zea in the USA has been largely compromised by resistance. A rapid shift towards planting Bt cotton and maize producing Vip3Aa will accelerate evolution of resistance to Vip3Aa in H. zea. Research on the genetic basis of Vip3Aa resistance in H. zea is urgently needed, and can provide fundamental information for managing resistance in this pest. Here, we characterize the inheritance of Vip3Aa resistance in H. zea.

Helicoverpa zea对Vip3Aa Bt蛋白抗性的遗传基础

Helicoverpa zea是一种破坏性害虫，是北美地区表达Cry和Vip3Aa蛋白的玉米和棉花的靶标。在美国，Cry蛋白对玉米的抗药性已大大受到抗药性的影响。对种植Bt棉花和玉米生产Vip3Aa将加速性的进化Vip3Aa在迅速转变美洲棉铃虫。研究Vip3Aa抗性的遗传基础上，美洲棉铃虫迫切需要，并能在这种害虫抗性管理提供基础信息。在这里，我们表征了H. zea中Vip3Aa抗性的遗传。
