The Old‐World bollworm, Helicoverpa armigera (Hübner), was recently documented attacking cotton and soybean plants in Brazil; however, restricted basic knowledge on host plant interactions and landscape use in Brazil have limited the effectiveness of control measures. In this study, we evaluated the suitability of different crops commonly cultivated in Brazil as hosts for H. armigera and H. zea, and examined their contribution to the establishment and size of H. armigera and H. zea field populations. We also estimated the proportions of H. armigera and H. zea moths that used cotton, noncotton C3 plants, and C4 plants as hosts in four regions in Brazil through the length of the cropping season.

据报道,旧世界的棉铃虫Helicoverpa armigera(Hübner)袭击了巴西的棉花和大豆植物。然而,巴西关于寄主植物相互作用和景观利用的基本知识有限,限制了控制措施的有效性。在这项研究中,我们评估了巴西普遍种植作为主机上的不同作物的适宜棉铃虫美洲棉铃虫,并检查它们的建立和贡献大小棉铃虫美洲棉铃虫田间种群。我们还估计的比例棉铃虫美洲棉铃虫蛾即用棉,noncottonç 3种植物和C 4 整个种植季节,巴西四个地区的植物都是寄主。
