摘要
Rachiplusia nu（Guenée）历来是巴西大豆的次要害虫，但却是阿根廷大豆的主要害虫。从 2021 年起，两国都有关于 R. nu 对表达苏云金芽孢杆菌（柏林根）Cry1Ac 毒素的大豆造成伤害的报道。在本研究中，我们利用含 Cry1Ac 的叶片组织筛选出对 Cry1Ac 有抗性和易感性的 R. nu 株系，并描述了抗性遗传、交叉抗性模式和适应成本。
Genetic basis of resistance to Cry1Ac in Rachiplusia nu (Lepidoptera: Noctuidae): inheritance mode, cross-resistance patterns and fitness cost
Rachiplusia nu (Guenée) was historically a secondary soybean pest in Brazil, but a key soybean pest in Argentina. From 2021 onwards, injury caused by R. nu has been reported in soybean that expresses the Cry1Ac toxin from Bacillus thuringiensis (Berliner) in both countries. In this study, we selected resistant and susceptible strains of R. nu to Cry1Ac using Cry1Ac-containing leaf tissue and characterized the inheritance of resistance, cross-resistance patterns and fitness cost.
期刊介绍：
Pest Management Science is the international journal of research and development in crop protection and pest control. Since its launch in 1970, the journal has become the premier forum for papers on the discovery, application, and impact on the environment of products and strategies designed for pest management.
