摘要

表达苏云金芽孢杆菌Cry和Vip3Aa杀虫蛋白的转基因作物是控制秋粘虫（Spodoptera frugiperda）种群的主要工具。秋粘虫原生区对Cry蛋白的抗性进化增加了对Vip3Aa抗性的依赖性和选择性。在这项研究中，我们确定了原产于美国路易斯安那州的frugiperda LA-RR菌株对Vip3Aa的抗性机制。

Reduced processing and toxin binding associated with resistance to Vip3Aa in a strain of fall armyworm (Spodoptera frugiperda) from Louisiana

Transgenic crops expressing Cry and Vip3Aa insecticidal proteins from the bacterium Bacillus thuringiensis are a primary tool for controlling fall armyworm (Spodoptera frugiperda) populations. The evolution of resistance to Cry proteins in the native range of the fall armyworm has increased reliance and intensified the selection of resistance to Vip3Aa. In this study, we identified mechanisms of resistance to Vip3Aa in the LA-RR strain of S. frugiperda originating from Louisiana (USA).
