The voracious invaders feed in large numbers on the leaves and stems of more than 350 plant species, including staple crops such as maize, cotton, rice, and sorghum, with maize being the preferred host. The insect is among the most destructive transboundary pests. The outlook is dire: fall army worm comes with serious consequences.Ī More Than 50% Potential Yield Loss Drastically Impacting Farmers’ Livelihoods To date, fall armyworm has spread to over 70 countries. During the first half of 2021, it was confirmed in New Caledonia and the Canary Islands of Spain in Europe. As of May 2020, it reached Mauritania, Timor-Leste and United Arab Emirates. In January 2020 it was detected in Australia in far north Queensland, and in a mere three months was considered established in the country.

Indigenous to the tropical and subtropical regions of the Americas, fall armyworm in maize ( Spodoptera frugiperda) was first reported in 2016, followed by rapid spread throughout sub-Saharan Africa, and by 2018 began to spread like wildfire into the Indian subcontinent, China and Southeast Asia. And as if that wasn’t enough, a second – and equally devastating -transboundary and invasive pest continues to invade parts of the eastern hemisphere: fall armyworm (FAW). Last year, farmers in East Africa, Southwest Asia and areas of the Middle East battled their worst desert locust outbreak in decades.
