A new 3-D animation video published yesterday shows farmers how to scout for and identify the fall armyworm (Spodoptera frugiperda).
The video shows scouting techniques and highlights the importance of identifying any pest damage at the early stages of crop growth. If the fall armyworm is present, integrated pest management practices can help farmers protect against this pest.
Farmers should avoid applying an indiscriminate amount of chemical pesticides, as that will lead to the fall armyworm building resistance to pesticides. It may also cause harm to people and to the environment.
The video was produced by Scientific Animations Without Borders (SAWBO), funded by USAID and developed by the International Maize and Wheat Improvement Center (CIMMYT), the International Institute of Tropical Agriculture (IITA) and Michigan State University.

The fall armyworm (FAW), Spodoptera frugiperda, a devastating insect-pest, has been identified for the first time on the Indian subcontinent. Native to the Americas, the pest is known to eat over 80 plant species, with a particular preference for maize, a main staple crop around the world. The fall armyworm was first officially reported in Nigeria in West Africa in 2016, and rapidly spread across 44 countries in sub-Saharan Africa. Sightings of damage to maize crops in India due to fall armyworm mark the first report of the pest in Asia.
Scientists from the College of Agriculture at the University of Agricultural and Horticultural Sciences (UAHS) confirmed the arrival of the pest in maize fields within campus grounds in Shivamogga, in the state of Karnataka, southern India. Both morphological and molecular techniques confirmed the identity as FAW.
A pest alert published on July 30 by the National Bureau of Agricultural Insect Resources (NBAIR), part of the Indian Council of Agricultural Research (ICAR), further confirmed a greater than 70% prevalence of fall armyworm in a maize field in the district of Chikkaballapur, in the state of Karnataka. Unofficial reports of incidence of FAW are rapidly emerging from several states in India, including Andhra Pradesh, Maharashtra and Telangana.
The pest has the potential to spread quickly not only within India, but also to other neighboring countries in Asia, owing to suitable climatic conditions.

“The strategies outlined in this manual can be of great importance to farmers in India when dealing with this insect pest. FAW is indeed one of the most destructive crop pests, and there is no option than to adopt an integrated pest management strategy to effectively tackle this complex challenge,” said B.M. Prasanna, director of MAIZE and the Global Maize Program at CIMMYT. “MAIZE and partners are dedicated to finding solutions to this problem that will protect the food security and incomes of smallholder farmers across Asia and Africa.”
Other regions are at risk as well. Researchers have warned of the potential impacts if FAW spreads to Europe, where customs inspectors have already reported having discovered and destroyed the pest on quarantined crops imported from Africa on several occasions.
Global experts on maize and key stakeholders in Asia will gather together in Ludhiana, India, on October 8-10, 2018, for the 13th Asian Maize Conference to discuss pressing issues to the crop across the continent, including the spread of fall armyworm. The conference, organized by the Indian Council of Agricultural Research (ICAR), the Indian Institute of Maize Research (IIMR), CIMMYT, MAIZE, Punjab Agricultural University (PAU) and the Borlaug Institute for South Asia (BISA), is expected to attract more than 250 participants from almost all the major maize-growing countries in Asia.
Nairobi, Kenya (CIMMYT) – A new comprehensive integrated pest management (IPM)-based technical guide produced by international experts will help scientists, extension agents and farmers to tackle the fall armyworm (Spodoptera frugiperda), which has rapidly spread across the African continent in the last two years, decimating maize crops in its path.
Native to North America, the fall armyworm has recently emerged as a major threat in Africa, where it has been identified in over 30 countries since it was first confirmed on the continent in January 2016. The pest can potentially feed on 80 different crop species but has a preference for maize, which poses a significant threat to the food security, income and livelihoods of over 300 million African smallholder farm families that consume maize as a staple crop.
“The potential impact of the fall armyworm as a major food security and economic risk for African nations cannot be overstated,” said Martin Kropff, director general at CIMMYT.
If proper control measures are not implemented, the fall armyworm could cause extensive maize yield losses of up to $6.2 billion per year in just 12 countries in Africa where its presence has been confirmed, according to the Centre for Agriculture and Biosciences International (CABI).
“The fall armyworm poses an enormous and wide-scale risk to the livelihoods of several million African smallholders, and requires urgent deployment of an IPM strategy and quick response from all stakeholders,” said B.M. Prasanna, director of MAIZE and the Global Maize Program at CIMMYT. “The Fall Armyworm Integrated Pest Management Guide provides comprehensive details on the best management practices to help smallholder farmers effectively and safely control the pest while simultaneously protecting people, animals and the environment.”
