Description
Summary:Keywords Spodoptera frugiperda, Pesticide resistance; Bt toxin resistance; Resistance mechanism; Pest management techniques Fall armyworm Spodoptera frugiperda (Smith) is a major migratory insect belonging to Noctuidae, Lepidoptera, and is native to tropical and subtropical regions of America111. In recent years, the rapid spread of S/ frugiperda in most tropical and subtropical regions has attracted extensive attention from the international community, and the resistance to chemical insecticides and Bt toxins poses a severe challenge to the control of this pest. In this paper , the status and mechanism of S/ frugiperda resistance to insecticide and Bt toxins were discussed, and the resistance control technology against Bt target pests such as S/ frugiperda was introduced. [...]combined with the actual agricultural production in China, the strategies of controlling S/ frugiperda were discussed. 1Status of S. frugiperda Resistance to Chemical Insecticides and Bt Crops 1.1Resistance to chemical insecticides Chemical pesticides are featured by quick effect, easy operation, not restricted by region and season, high economic benefits, which occupy an important position in the control of agriculture diseases and insect pests for a long time. In Brazil, Bt corn could be planted twice a year and there are multiple and overlapping generations of S. frugiperda every year, however, the proportion of conventional corn refuge is severely insufficient, this put great selection pressure on S. frugiperda132'351.
