Fall armyworm (FAW) is present in 109 countries in Africa, the Middle East, South and East Asia, and Oceania, and it has spread due to rapid increases in global trade. Maize is highly susceptible to the disease, but it affects more than 300 plant species.
Research by organizations such as the International Maize and Wheat Improvement Center (CIMMYT), CGIAR and CABI has developed effective strategies and tools for managing the disease, such as improved seed, proven agronomic practices, and biologic and chemical crop-protection tools.
An article in The Farming Forum explores FAW prevention developments and partnerships that are helping smallholder farmers protect their crops against this devastating disease.
Since the outbreak of FAW was reported in 2016, maize yields have dropped by between 30-50 percent, increasing the country’s challenges for food security.
Prasanna Boddupalli, Director of the Global Maize Program at CIMMYT, said, ″We want farmers to dissociate from application of synthetic toxic pesticides and chemicals but revert to use of combined approaches like use of resistant varieties, bio-pesticides and related biological control methods that are environmentally friendly.”
Preliminary assessment of the viability of naturally tolerant maize varieties from Mexico suggests that at least two or three resistant varieties may be approved after certification from the regulator.

The fall armyworm is a destructive polyphagous pest that feeds on more than 300 crop species, with a particular appetite for maize. The pest was first reported in Asia in 2018 and has been spreading in the region since then, especially in maize-producing countries of South Asia.
Several campaigns on identifying and managing fall armyworm have been conducted in South Asia, yet the challenge to control the pest remains. The damage caused by fall armyworm to farmers’ fields was reported widely during the 2022 spring maize season in Pakistan and Nepal’s Terai region. Many maize farmers complained about the current economic downturn, price hike of agricultural commodities and the unavailability of safe pesticides to reduce crop losses.
On 21 July 2022, the International Maize and Wheat Improvement Center (CIMMYT) initiated a refresher webinar to share the latest scientific advances and best practices for identifying and managing fall armyworm in South Asia. The platform extended an opportunity for the participants to understand and learn about effective integrated pest management (IPM) approaches being practiced in the region. It also addressed the importance of enabling policies that are crucial to foster innovations to reduce crop yield loss and save the environment from hazardous effects of toxic pesticides.
The Nepal Seed and Fertilizer Project (NSAF) team, supported by the United States Agency for International Development (USAID) and implemented by CIMMYT, organized the virtual event in collaboration with Nepal’s Plant Quarantine and Pesticide Management Center, the Nepal Agricultural Research Council, Nepal’s National Maize Research Program, the Maize and Millet Research Institute in Pakistan, the University of Agriculture Faisalabad and CGIAR’s Plant Health Initiative.
Govinda Prasad Sharma, Secretary of Nepal’s Ministry of Agriculture and Livestock Development and Jason Seuc, director of the Economic Growth Office at USAID Nepal, delivered their opening remarks during the inaugural session. The Secretary emphasized the use of safer methods, including but not limited to mass rearing and releasing of natural enemies of fall armyworm and the deployment of fall armyworm tolerant maize varieties.
“USAID will continue working with partners to advocate and promote IPM practices till the pest becomes of non-economic importance,” said Seuc.
BM Prasanna, director of CIMMYT’s Global Maize Program and OneCGIAR Plant Health Initiative lead emphasized the importance of IPM practices to manage the pest. Prasanna discussed the global efforts to control the pest and shared the progress of fall armyworm tolerant maize seeds which are being released and deployed by CIMMYT partners to help resource poor farmers, especially in Africa.
AbduRahman Beshir, NSAF’s seed systems lead, emphasized the importance of the event and acknowledged the participation of approximately 525 attendees from public and private research institutions, academicians, civil society, private sector, policy decision-makers, CGIAR centers and USAID Nepal. The webinar gathered attendees from 15 countries, including Nepal, India, Bangladesh, Pakistan, Thailand, Myanmar, Sri Lanka and China.
Experts from South Asia presented on a range of topics including the status of fall armyworm and its management in Nepal, Pakistan, Bangladesh and the Pacific Region, IPM practices and experience of using safe pesticides, breeding for native genetic resistance to fall armyworm, and biological control and push-pull strategies. The experts emphasized on the need for collective efforts to strengthen national and international coordination, favorable policies, deployment of fall armyworm tolerant maize varieties, and best response interventions to help farmers battle the fall armyworm and limit its spread.
Efforts to mitigate the impact of fall armyworm attacks are still ongoing. CIMMYT is continuously working to alert farmers and stakeholders on the IPM practices of fall armyworm in the region.

The Accelerating Genetic Gains in Maize and Wheat (AGG) Project, which is halfway through its implementation, continues to register impressive achievements. At a meeting focusing on the project’s Maize component, held in Nairobi during July 25-28, B.M. Prasanna, Director of the Global Maize Program at the International Maize and Wheat Improvement Center (CIMMYT), highlighted the project’s major achievements in the opening session.
“One of the most important achievements of this project is increasing use of powerful tools and technologies to increase genetic gains in maize breeding pipelines in Africa,” said Prasanna. He noted that the AGG partners are showing keen interest in doubled haploid-based maize breeding. Prasanna pointed out that currently work is ongoing to produce third-generation tropicalized haploid inducers which, in combination with molecular markers, will support accelerated development of improved maize germplasm, a key objective of the AGG Project.
Prasanna also pointed out a significant increase in adoption of stress-tolerant maize in Africa – from less than half a million hectares cultivated under stress tolerant maize varieties in 2010, to 7.2 million hectares currently in 13 African countries, benefitting 44.5 million people. He explained that drought-tolerant maize is not only a productivity enhancing tool but also an innovation for improving the welfare of farmers. “It reduces the probability of crop failure by 30 percent and provides an extra income to farmers at a rate of approximately $240 USD per hectare, equivalent to about nine months of food for a family at no additional cost,” he said, adding that the essence of research is taking improved genetics to farmers and impacting their lives.
He noted there is remarkable progress in maize varietal turnover in sub-Saharan Africa, pointing out particularly efforts in Ethiopia, Uganda, Zambia and Zimbabwe, where old maize varieties, some dating as far back as 1988, have been replaced with newer climate-resilient varieties. Prasanna highlighted the need to engage with policy makers to put in place appropriate legislation that can accelerate replacement of old or obsolete varieties with improved genetics.
Prasanna stressed on the importance of rapid response to transboundary diseases and insect-pests. CIMMYT has established fall armyworm (FAW) screening facility at Kiboko, Kenya, and that more than 10,000 maize germplasm entries have been screened over the last three years. He applauded South Sudan for being the first country in sub-Saharan Africa to recently release three CIMMYT-developed FAW-tolerant hybrids. He said CIMMYT’s FAW-tolerant inbred lines have been shared with 92 institutions, both public and private, in 34 countries globally since 2018.
Kevin Pixley, CIMMYT Global Genetic Resources Director and Deputy Director General, Breeding and Genetics, encouraged the participants to continuously reflect on making innovative contributions through the AGG project, to serve smallholder farmers and other stakeholders, and to offer sustainable solutions to the food crisis that plagues the world.

Synergies across crops and teams
Pixley pointed out that though the meeting’s focus was on maize, the AGG Project has both maize and wheat components, and the potential for learning between the maize and wheat teams would benefit many, especially with the innovative strides in research from both teams.
Pixley referenced a recent meeting in Ethiopia with colleagues from the International Institute of Tropical Agriculture (IITA), the International Center for Tropical Agriculture (CIAT) and CIMMYT, where discussions explored collaboration among CGIAR centers and other stakeholders in strengthening work on cowpea, chickpea, beans, sorghum, millet and groundnut crops. He noted that maize, wheat and the aforementioned crops are all critical in achieving the mission of CGIAR.
“CIMMYT has been requested, since August of last year, by CGIAR to initiate research projects on sorghum, millet and groundnut because these crops are critical to the success of achieving the mission of CGIAR,” said Pixley. “So, we have recently initiated work on the Accelerated Varietal Improvement and Seed Systems in Africa (AVISA) project together with partners. This is the first step towards OneCGIAR. It’s about synergies across crops and teams.”
Collaborative research commended
The meeting’s Chief Guest, Felister Makini, Deputy Director General – Crops of the Kenya Agricultural and Livestock Research Organisation (KALRO), commended the collaborative research undertaken by CIMMYT and other CGIAR partners. She noted that the partnerships continue to build on synergies that strengthen institutional financial, physical and human resources. She attested that collaboration between KALRO and CGIAR dates back to the 1980s, beginning with training in maize breeding, and then subsequent collaboration on developing climate-adaptive improved maize varieties and training of KALRO technicians in maize lethal necrosis (MLN) screening and management among other areas.
Maize and wheat are staple food sources in Kenya and sub-Saharan Africa and as the population increases, new methods and approaches must be found to accelerate development and deployment of improved maize and wheat varieties. She challenged the partners to intensify research and come out with high-yielding varieties that are resistant or tolerant to a wide range of biotic and abiotic stresses.
The Inaugural Session also featured remarks from the representatives of the AGG funders – Gary Atlin from the Bill & Melinda Gates Foundation, Jonna Davis from the Foundation for Food and Agriculture Research (FFAR), and John Derera from IITA, an AGG project partner.
A total of 116 participants, including representatives from National Agricultural Research Systems (NARS) in 13 AGG-Maize partner countries in Africa and seed companies, participated in the meeting. Participants also visited the KALRO-CIMMYT MLN Screening Facility at Naivasha, and KALRO-CIMMYT maize experiments at Kiboko, Kenya, including the work being done at the maize doubled haploid and FAW facilities.
CIMMYT-Bangladesh country representative Timothy J. Krupnik was the guest of honor at a day-long workshop organized by Bangladesh Agricultural Research Institute (BARI) on fall armyworm management in the country.
Together with the United States Agency for International Development (USAID) and Feed the Future, the International Maize and Wheat Improvement Center (CIMMYT) and the CGIAR Research Program on Maize (MAIZE) are pleased to announce the release of “Fall Armyworm in Asia: A Guide for Integrated Pest Management.”
The publication builds on intensive, science-based responses to fall armyworm in Africa and Asia.
“I have encountered few pests as alarming as the fall armyworm,” wrote USAID Chief Scientist Rob Bertram in the guide’s Foreword. “This publication … offers to a broad range of public and private stakeholders — including national plant protection, research and extension professionals — evidence-based approaches to sustainably manage fall armyworm,” Bertram adds.
“Partners from a wide array of national and international institutions have contributed to the mammoth task of formulating various chapters in the guide,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program and of MAIZE. “While the publication is focused on Asia, it provides an updated understanding of various components of fall armyworm integrated pest management that could also benefit stakeholders in Africa.”
In January 2018, CIMMYT and USAID published a similar guide on integrated pest management of fall armyworm in Africa, which reached a large number of stakeholders globally and is widely cited. Prasanna spearheaded the development and publication of both guides.
The fall armyworm is an invasive pest that eats more than 80 different crops, but has a particular preference for maize.
It is native to the Americas. It was first reported in Africa in 2016, and quickly spread throughout the continent. It reached India in 2018. It has since been reported in many other countries across Asia and the Pacific, and it reached Australia in 2020.
Millions of families in these regions are highly dependent on maize for their income and their livelihoods. If the fall armyworm keeps spreading, it will have disastrous consequences for them.
Scientists at CIMMYT have been working hard to find solutions to help farmers fight fall armyworm. Researchers have developed manuals for farmers, with guidelines on how to manage this pest. They have also formed an international research consortium, where experts from diverse institutions are sharing knowledge and best practices. Consortium members share updates on progress in finding new ways to tackle this global challenge. Scientists are now working on developing new maize varieties that are resistant to fall armyworm.
The fall armyworm can’t be eradicated — it is here to stay. CIMMYT and its partners worldwide will continue to work on this complex challenge, so millions of smallholder farmers can protect their crops and feed their families.
In our hyper-connected world, it should come as no surprise that recent years have shown a major uptick in the spread of transboundary pests and diseases. Integrated approaches have been effective in sustainably managing these border-jumping threats to farmers’ livelihoods and food security.
But a truly integrated approach accounts for not just the “cure,” but also how it can be sustainably incorporated into the agri-food system and social landscape. For example, how do we know if the farmers who adopt disease- and pest-resistant seed will be able to derive better incomes? And how do we ensure that incentives are aligning with community norms and values to enable better adoption of integrated disease or pest management approaches?
Experts from across the CGIAR research system and its partners weighed in on this topic in the recent webinar on Integrated Pest and Disease Management, the third in the International Year of Plant Health Webinar series. Panelists shared valuable perspectives on the science of outbreaks, the social dimensions of crop pest and disease control, zoonotic disease risk, and how national, regional and global organizations can better coordinate their responses.
“The combination of science, global partnerships and knowledge helps all of us be better prepared to avoid the losses we’ve seen. . . Today, we’re going to see what this looks like in practice,” said Rob Bertram, chief scientist for the Bureau for Resilience and Food Security at USAID, and moderator of the event.

Understanding the sources
Wheat and maize, the key crops studied at the International Maize and Wheat Improvement Center (CIMMYT) are no stranger to destructive diseases or pests, with fall armyworm, wheat blast, or maize lethal necrosis topping the list. But other staple crops and their respective economies are suffering as well — from infestations of cassava brown streak, potato cyst nematode, taro blight, desert locusts, and fusarium wilt, just to name a few.
What are the reasons for the expansion of these outbreaks? B.M. Prasanna, director of CIMMYT’s Global Maize Program explained that there are several: “Infected seed or planting material, vector movement, strong migratory capacity, contaminated field equipment, improper crop production commercialization practices, and global air and sea traffic” are all major causes.

Preventing outbreaks is always better than scrambling to find a cure, but as Prasanna pointed out, this requires a holistic, multi-institutional strategy including surveillance and early warning, quarantine and phytosanitary regulations, and technological solutions. Better access to monitoring and surveillance data, and sensitive, easy-to-use and affordable diagnostic equipment are essential, as is the proactive deployment of resistant crop varieties.
Building awareness about integrated disease and pest management is just as important, he told the attendees. “We must remember that IPM is not just Integrated Pest Management, but also ‘Integrating People’s Mindsets.’ That remains a major challenge. We need to think beyond our narrow disciplines and institutions and really come together to put IPM solutions into farmers’ fields,” Prasanna said.
Not all outbreaks are the same, but lessons can be shared
Regina Eddy, coordinator for the Fall Armyworm Interagency Task Force at USAID, works closely with the complex issue of scaling when it comes to disaster response and the roles of national, regional and global organizations.
“We need to develop inclusive partner stakeholder platforms, not designed ‘for them,’ but ‘with them,’” said Eddy. “We cannot tackle food security issues alone. Full stop.”
Closing the gap between social and biophysical science
Nozomi Kawarazuka, social anthropologist at the International Potato Center (CIP) explained how researchers can improve the uptake of their new seed, innovation, or agronomic practice by involving social scientists to understand the gender norms and social landscape at the beginning of the project — in the initial assessment phase.
Kawarazuka highlighted how involving women experts and extension workers in sectors that are typically male-dominated helps reduce bias and works towards changing perceptions.
“In South Asia, women farmers hesitate to engage with male government extension workers,” she said. “Women experts and extension workers reduce this barrier. Gender and social diversity in the plant health sector is an entry point to develop innovations that are acceptable to women as well as men and helps scale up adoption of innovations in the community.

The world is watching agriculture and livestock
Zoonotic diseases, or zoonoses, are caused by pathogens spread between animals and people. Understanding zoonotic disease risk is an essential and timely topic in the discussion of integrated pest management. Poor livestock management practices, lack of general knowledge on diseases and unsafe yet common food handling practices put populations at risk.
“It’s especially timely, [to have this] zoonosis discussion in our COVID-plagued planet. The whole world is going to be looking to the food and agricultural sectors to do better,” Bertram said.
Annet Mulema, a gender and social scientist at the International Livestock Research Institute (ILRI) described results of a study showing how community conversations transformed gender relations and zoonotic disease risk in rural Ethiopia, where 80% of the population depends on agriculture and has direct contact with livestock.
“There were noticeable changes in attitude and practices among men and women regarding unsafe handling of animals and consumption of animal-source foods,” Mulema explained. “Community conversations give men and women involved a voice, it allows for a variety of ideas to be expressed and discussed, leads to community ownership of conclusions and action plans, and opens communication channels among local service providers and community members.”

Local to global, and global to local
Panelists agreed that improving capacity is the most powerful lever to advance approaches for integrated pest management and plant health, while connected and inclusive partnerships along the value chain make the whole system more resilient. The amount of scientific knowledge on ways to combat plant pests and diseases is increasing, and we have new tools to connect the global with the local and bring this knowledge to the community level.
The fourth and final CGIAR webinar on plant health is scheduled for March 31 and will focus on a the intersectional health of people, animals, plants and their environments in a “One Health” approach.
The International Maize and Wheat Improvement Centre (CIMMYT) has developed new maize hybrid varieties showing promising resistance to the destructive fall armyworm pest, which has been causing huge crop losses ever since the pest was first reported in Africa in 2016.
A collage of maize images accompanies a CIMMYT announcement about fall armyworm-tolerant maize hybrids for Africa.
The International Maize and Wheat Improvement Center (CIMMYT) is pleased to announce the successful development of three CIMMYT-derived fall armyworm-tolerant elite maize hybrids for eastern and southern Africa.
Fall armyworm (Spodoptera frugiperda) emerged as a serious threat to maize production in Africa in 2016 before spreading to Asia in 2018. Host plant resistance is an important component of integrated pest management (IPM). By leveraging tropical insect-resistant maize germplasm developed in Mexico, coupled with elite stress-resilient maize germplasm developed in sub-Saharan Africa, CIMMYT worked intensively over the past three years to identify and validate sources of native genetic resistance to fall armyworm in Africa. This included screening over 3,500 hybrids in 2018 and 2019.
Based on the results of on-station screenhouse trials for fall armyworm tolerance (under artificial infestation) conducted at Kiboko during 2017-2019, CIMMYT researchers evaluated in 2020 a set of eight test hybrids (four early-maturing and four intermediate-maturing) ) against four widely used commercial hybrids (two early- and two intermediate-maturing) as checks. The trials conducted were:
“No choice” trial under fall armyworm artificial infestation in screenhouses in Kiboko, Kenya: Each entry was planted in 40 rows in a separate screenhouse compartment (“no-choice”), and each plant infested with seven fall armyworm neonates 14 days after planting. Foliar damage was assessed 7, 14 and 21 days after infestation. Ear damage and percent ear damage were also recorded, in addition to grain yield and other agronomic parameters.
On-station trials in eastern Africa: The trials, including the eight test entries and four commercial checks, were conducted at six locations in Kenya during the maize cropping season in 2020. Entries were evaluated for their performance under managed drought stress, managed low nitrogen stress, and under artificial inoculation for Turcicum leaf blight (TLB) and Gray leaf spot (GLS) diseases. The three-way cross CIMMYT test hybrids and their parents were also characterized on-station for their seed producibility, including maximum flowering time difference between parents, and single-cross female parent seed yield.
The eight test entries with fall armyworm tolerance were also included in the regional on-station trials (comprising a total of 58 entries) evaluated at 28 locations in Kenya and Tanzania. The purpose of these regional trials was to collect data on agronomic performance.
On-farm trials in Kenya: The eight test hybrids and four commercial checks were evaluated under farmers’ management conditions (without any insecticide spray) at 16 on-farm sites in Kenya. Each entry was planted in 20-row plots, and data was recorded on natural fall armyworm infestation. Foliar damage was assessed 7, 14, 21, 28 and 35 days after germination together with insect incidence. Ear damage and percent ear damage were also recorded, besides grain yield and other agronomic parameters.
Figure 1. Responses of CIMMYT-derived fall armyworm tolerant hybrids versus susceptible commercial checks at the vegetative stage (A & B) and at reproductive stage (C & D), respectively, after fall armyworm artificial infestation under “no choice” trial in screenhouses at Kiboko, Kenya. Note the difference in the harvest of a FAWTH hybrid (E) versus one of the commercial susceptible hybrid checks (F), besides the extent of damage caused by fall armyworm to the ears of the susceptible check (visible as blackish spots with no grains in the ears).
Summary of the data
“No-choice” trials in screenhouses at Kiboko: Significant differences were observed between the three selected fall armyworm tolerant hybrids (FAWTH2001-2003) and the commercial benchmark hybrid checks at the vegetative and grain filling stages and at harvest (Figure 1). In the fall armyworm artificial infestation trial, the three selected FAWTH hybrids yielded 7.05 to 8.59 t/ha while the commercial checks yielded 0.94-1.03 t/ha (Table 1).
On-station trials: No significant differences were observed between the three selected FAWTH hybrids and the commercial checks for grain yield and other important traits evaluated under optimum, managed drought stress, low nitrogen stress, TLB and GLS diseases (Table 1). The three FAWTH hybrids recorded excellent synchrony in terms of flowering between the female and male parents, and very good female parent seed yield (Table 1).
On-farm trials: There were significant differences in terms of foliar damage ratings between the FAWTH hybrids and the commercial checks. For ear damage, the differences were not statistically significant. The grain yields did not vary significantly under natural infestation in the on-farm trials because of the very low incidence of fall armyworm at most sites.
Native genetic resistance to fall armyworm in maize is partial, though quite significant in terms of yield protection under severe fall armyworm infestation, as compared to the susceptible commercial checks. Sustainable control of fall armyworm is best achieved when farmers use host plant resistance in combination with other components of integrated pest management, including good agronomic management, biological control and environmentally safer pesticides.
Next Steps
Together with national agricultural research system (NARS) partners, CIMMYT will nominate these FAWTH hybrids for varietal release in target countries in sub-Saharan Africa, especially in eastern and southern Africa. After national performance trials (NPTs) and varietal release and registration, the hybrids will be sublicensed to seed company partners on a non-exclusive, royalty-free basis for accelerated seed scaling and deployment for the benefit of farming communities.

Fall armyworm continues to cause havoc in Africa. Farmers in Somalia have not been spared since this unwelcome guest showed up in the country over three years ago. As part of the mitigation measures, the Somali Agriculture Technical Group (SATG) in partnership with the International Maize and Wheat Improvement Center (CIMMYT) and the International Committee of the Red Cross (ICRC) recently conducted online trainings on fall armyworm management for sustainable crop protection. The online trainings, targeting national agriculture stakeholders in the country, took place on August 25 and September 30, 2020, with nearly 250 participants attending both webinars.
“This is the first of our efforts to reach out to our partners in Somalia, especially the Somali Agriculture Technical Group and the national agricultural research system, to increase the awareness on the integrated pest management approaches that can help combat this highly destructive pest,” said B.M. Prasanna, Director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize (MAIZE).
“This training was designed to help participants to gain a better understanding about fall armyworm, how to identify it, how to monitor and scout for it, how to effectively implement a management strategy that is environmentally and ecologically benign, in order to protect the food security and livelihoods of farmers and their families,” Prasanna said.
An integrated pest management strategy for sustainable control of fall armyworm should consider various interventions, including regular scouting and monitoring of the pest in the fields, host plant resistance, biological and biorational control, agroecological management, and use of environmentally safer pesticides and good agronomic practices tailored for the socio-cultural and economic contexts of the farmers. Ultimately, the purpose of a functional integrated pest management approach is to suppress pest population by applying techniques that minimize human and environmental harm, while protecting the crops from economic damage.
“I am happy to see the expertise from high levels of research at CIMMYT, icipe, IITA, universities, SATG and the humanitarian sector coming together to tackle and solve problems linked to food production and consumption. I believe that such important trainings have great value for Somalia, and should be further strengthened and encouraged,” said Abdalla Togola from the ICRC.

Hussein Haji, the Executive Director of SATG was optimistic that the training would go a long way to empower farmers in Somalia, through their cooperatives, and could lead to better ways of tackling challenges such as fall armyworm, already made worse by other stresses like drought and desert locusts.
“Through our extension workers, we hope this information will trickle down to our cooperatives, who produce mainly maize and sorghum seed in Somalia,” he added.
This comes on the back of a partnership between the ICRC and SATG to implement activities intended to improve food production among rural communities in six regions of Somalia. The partnership would enhance quality seed production with a focus on maize and sorghum, the major staple crops in the country.
Besides Prasanna, the key resource persons included Dan McGrath (Professor Emeritus, Oregon State University, USA), Joseph Huesing (CIMMYT Consultant on integrated pest management) and Georg Goergen (Entomologist, International Institute of Tropical Agriculture), Frederic Baudron (CIMMYT Systems Agronomist), Anani Bruce (CIMMYT Entomologist), Yoseph Beyene (CIMMYT Regional Breeding Coordinator for Africa) and Saliou Niassy (Head of Agricultural Technology Transfer Unit, International Center of Insect Physiology and Ecology).
The fall armyworm, a voracious caterpillar officially reported for the first time in Africa in Nigeria in 2016, remains a serious pest with devastating consequences on millions of farmers’ food and livelihood security. The pest has spread quickly throughout sub-Saharan Africa, primarily attacking maize and sorghum, two main staple crops in the region. The Food and Agriculture Organization of the United Nations (FAO) estimates up to 18 million tons of maize are lost to the pest annually, at an estimated economic loss of $4.6 billion.
To reduce the losses, experts have been recommending a toolbox of integrated pest management (IPM) practices to minimize the damage on smallholder farmers’ fields. Scientists at CIMMYT are also working intensively to develop improved maize varieties with native genetic resistance to this devastating insect pest.

To the first-time observer, the aftermath of a fall armyworm infestation must be terrifying. The larvae can cause significant damage to an entire field in a single night, leaving once-healthy leaves looking like tattered rags.
A new instructional video, which will air in Bangladesh, aims to combat both the pest and the distress its appearance can cause with detailed, actionable information for farmers. The video describes how to identify the pest, its lifecycle and the kind of damage it can do to maize — among other crops — and provides techniques for identifying, assessing, and combating an infestation.
This video was developed by the International Maize and Wheat Improvement Center (CIMMYT) with support from the Department of Agricultural Extension (DAE) and the Bangladesh Wheat and Maize Research Institute (BWMRI), as part of the project Fighting back against fall armyworm in Bangladesh. Supported by USAID’s Feed the Future Initiative and Michigan State University, this CIMMYT-led project works in synergy with the Cereal Systems Initiative for South Asia (CSISA), and with national partners to mitigate the impact of this invasive pest on smallholder farmers’ livelihoods.
The video is available in Bangla with English captions.
This year’s Nobel Peace Prize award is likely to turn the eyes of the world to the millions of people who suffer from, or face the threat of hunger. CGTN Africa has been running a series on food production in the continent. The series is in line with this year’s Nobel Peace Prize theme — making food security an instrument of peace. This episode focuses on the impact of improved seeds.
When we talk about the impact of agricultural research we often rely on numerical metrics: percent increase in yield, percent decrease in crop loss, adoption rates, etcetera. For farmers on the ground, however, the impact can be much harder to boil down to a few numbers. Hiding behind every statistical table are real stories of dreams dashed or fulfilled, of everyday people trying to survive and flourish.
A new educational video powerfully dramatizes this point through the story of Jamal Mia and his daughter Rupa. Jamal’s dreams to own a house and see Rupa enroll in college are threatened when his maize crop is attacked by fall armyworm. An encounter with an agricultural extension officer puts Jamal on track to tackle the infestation, save his crop and secure his family’s wellbeing.
The video was developed by CIMMYT with support from Bangladesh’s Department of Agricultural Extension and the Bangladesh Wheat and Maize Research Institute (BWMRI), as part of a project titled “Fighting back against fall armyworm in Bangladesh.” Supported by USAID’s Feed the Future Initiative and Michigan State University, this CIMMYT-led project works in synergy with the Cereal Systems Initiative for South Asia (CSISA) and with national partners to mitigate the impact of this invasive pest on smallholder farmers’ livelihoods.
The video was filmed in Dinajpur district, Bangladesh, and is available in Bangla with English captions.
