The Fall Armyworm is a pest that primarily affects crops like corn, rice, and sorghum. It is known for its rapid reproduction and ability to travel long distances, making it a significant threat to agriculture. The larvae are green or brown and can consume large amounts of plant material, leading to substantial crop damage. Originally from the Americas, the Fall Armyworm has spread to various parts of the world, including Africa and Asia. Farmers often use integrated pest management strategies to control its population, which may include biological control methods and the use of insecticides.
