The invasive butterfly species Pseudaletia unipuncta, commonly known as the Asian Armyworm, has been wreaking havoc on citrus trees in areas of the United States. Native to Japan and China, the butterfly was first identified in Florida in late 2019. The larvae of the Asian Armyworm feed on the leaves, buds, and fruit of citrus trees and have been known to strip entire trees of their foliage. The larvae can survive in cold temperatures, making them especially difficult to eradicate. To manage the infestation, experts are focusing on preventive measures such as early detection and monitoring, as well as the use of insecticides and biological controls. The Asian Armyworm has the potential to cause significant damage to citrus production in Florida and other regions of the United States.
