A Review on Fall Armyworm (Spodoptera frugiperda) Insecticide Resistance

Abstract

The commonly known fall armyworm (Spodoptera frugiperda) is an important pest of corn, cotton, and other crops in the Americas, Africa, and Asia. The species is native to tropical and subtropical regions of the Americas, but it has spread to other parts of the world in recent years. The pest has a wide host range, including important crops like corn, cotton, rice, sorghum, and vegetables. Large populations of fall armyworms can cause significant damage to crops, leading to reduced yields and lower crop quality. The threat of insecticide resistance in S. frugiperda is a growing concern for agricultural production and food security. Insecticides are an important tool for managing fall armyworm populations, but the development of resistance to these chemicals has become a major issue in many regions. This pest has shown resistance to several classes of insecticides, including pyrethroids, organophosphates, and carbamates. To effectively manage insecticide resistance in S. frugiperda populations, it is important to consider these factors and develop integrated pest management strategies that take them into account. This may include the use of alternative control methods, such as biological control and cultural control, and the judicious use of insecticides to minimize selection pressure for resistance development. It is important for farmers, researchers, and policymakers to work together to develop and implement integrated pest management strategies that can effectively manage S. frugiperda populations while minimizing the development and spread of insecticide resistance.
