    Fall Armyworm Spodoptera frugiperda is an insect pest that feeds on more than 80 crop species, causing damage to such economically important crops as maize, rice, sorghum, paddy, legumes, vegetables and cotton, and leading to significant yield loss The United Republic of Tanzania is a leading producer of maize in East Africa region and the tenth producer in the world An estimated 6 59 million tonnes of maize are grown in the country each year by 4 5 million farm households, representing about 42 percent of Tanzanian farmers Primary outbreaks of FAW have been reported in Rukwa Kagera Pwani Geita Simiyu Mwanza, Morogoro Kilimanjaro and Njombe regions, with the Southern Highlands, the breadbasket of the country, and Southern regions also at high risk Because of the nature of FAW infestation, it is likely that the pest will colonize most African countries and have a negative impact on both food security and livelihoods.

    The Fall Armyworm (Spodoptera frugiperda), FAW, is an insect native to tropical and subtropical regions of the Americas. In the absence of natural control or good management, it can cause significant damage to crops. It prefers maize, but can feed on more than 80 additional species of crops, including rice, sorghum, millet, sugarcane, vegetable crops and cotton. FAO is taking an active role in coordinating partners’ activities, plans and approaches to provide sustainable solutions to the FAW challenge. An integral part of FAO’s sustainable management programme for FAW in Africa is the FAW Monitoring and Early Warning System (FAMEWS) that consists of a mobile app for data collection and a global platform for mapping the current situation.

    Worldwide, maize is the third most important cereal after rice and wheat. It occupies 197 million hectares of planted area. Asia contributes to nearly 30 percent of global maize supplies, and area and production of the crop is rapidly increasing in the continent. Minimum support prices, swelling market demand from the animal feed and processing industries, as well as human consumption, have all led to increased maize production in zones where precipitation limits rice cultivation. However, maize production is currently threatened by the arrival in Asia (in 2018) of the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) – a native to North America. It invaded India in 2018 and since then it has marched to most of the Asian countries. In 2019, its presence was confirmed in 13 Asian countries including Cambodia, China, India, Indonesia, Japan, the Lao People’s Democratic Republic, Malaysia, Myanmar, Nepal, the Philippines, the Republic of Korea, Sri Lanka, and Viet Nam. In 2020, it was confirmed in Australia, Timor-Leste and Papua New Guinea. In August 2021, it reached the Solomon Islands, posing a serious threat to other Pacific islands. FAW is a fast-dispersing, migratory, transboundary insect pest. While high FAW incidences have been reported on several crops in Asia, the most important economic damage caused is to maize (followed by sorghum). The FAW invasion threatens the food security of millions of family farms in Asia, with smallholder farmers being especially vulnerable. The negative economic impact of FAW is not only evident in yield loss: the pest also leads to a significant increase in insecticide applications, with associated health, environmental and cost issues. At the same time, resilience to FAW on the continent is currently weakened by the limited access to necessary tools, technologies and sustainable integrated pest management (IPM) practices for FAW. Thus, there is an urgent need to implement an effective approach to FAW management in Asia.
