Fall Armyworm

Fall Armyworm (FAW), or Spodoptera frugiperda, is an insect that is native to tropical and subtropical regions of the Americas. In its larva stage, it can cause significant damage to crops, in not well managed. It prefers maize, but can feed on more than 80 additional species of plants, including rice, sorghum, millet, sugarcane, vegetable crops and cotton. In Africa, FAW was first detected in Nigeria in January 2016 and has quickly spread across virtually all of sub-Saharan Africa. Because of trade and the moth's strong flying ability, it has the potential to spread further. Farmers will need great support to sustainably manage FAW in their cropping systems through Integrated Pest Management.
