“…The recent invasion of FAW in developing countries also has an important impact on household income and food security. For example, Tambo et al (2021) showed that households affected by FAW in Zimbabwe had a lower per capita income and were 12% more likely to experience hunger compared to unaffected households.…”

The fall armyworm (FAW), Spodoptera frugiperda (JE Smith, 1797), is a serious pest of several crops, particularly maize and other cereals. It has long been known as a pest in the Americas and has invaded most of Africa and parts of the Middle East, Asia, and Australia in the last six years. Its new status as an invasive species causing serious damage in many regions worldwide has highlighted the need for better understanding and has generated much research. In this article, we provide a comprehensive review of FAW covering its (i) taxonomy, biology, ecology, genomics, and microbiome, (ii) worldwide status and geographic spread, (iii) potential for geographic expansion and quarantine measures in place, and (iv) management including monitoring, sampling, forecasting, biological control, biopesticides, agroecological strategies, chemical control, insecticide resistance, effects of insecticides on natural enemies, as well as conventional and transgenic resistant cultivars. We conclude with recommendations for research to enhance the sustainable management of FAW in invaded regions.

“…In Zimbabwe, infestation with Fall Armyworm has led to substantial maize yield losses of up to 12% to 58% based on rigorous field scouting and farmers perception resulting in food insecurity [3] . Maize is the most important staple food crop in Africa and is predominantly grown by smallholder farmers for human consumption and livestock feed [3,4] . However, maize production has been affected for the majority of households due to attack by the Fall Armyworm.…”

Fall Armyworm (FAW), Spodoptera frugiperda, is prevalent in Zimbabwe, causing significant damage to maize and yield losses. Three synthetic insecticides (Nemesis, Ecoterex and Lamda-cyhalothrin) belonging to different chemical groups and neem bio-pesticide (Neem Leaf Extract) were tested for their efficacy against FAW under laboratory and field conditions. The aim of the study was to assess the effect of neem bio-pesticide and synthetic insecticides on the population of FAW larvae, level of leaf damage and maize grain yield in comparison with untreated control plants. In laboratory experiment, neem biopesticide and the three synthetic insecticides resulted in significantly higher FAW larval mortality (p < 0.05) at 24, 48 and 72 hours after application of treatments as compared with the untreated plants. Neem bio-pesticide and the synthetic insecticides caused highest percentage of larval mortality (> 90%) at 72 hours after treatment application. In the field, both bio-pesticide and synthetic insecticides resulted in significantly higher efficacy (p < 0.05) against fall armyworm larvae, reduced the level of leaf damage and increased maize grain yield as compared to the untreated control plants. The untreated maize plants were found to be extensively damaged by FAW as compared to those treated with insecticides and neem bio-pesticide. The highest efficacy was recorded on plants treated with Nemesis, followed by Neem Leaf Extract, Ecoterex and lastly Lamda-cyhalothrin, respectively. The neem bio-pesticide and synthetic insecticides which were used in this study showed high efficacy against FAW larvae and can be recommended to be used as components for integrated pest management (IPM) plans for FAW under smallholder farmer conditions in Zimbabwe and the rest of Africa.

“…Likewise, in the Ekiti state of Nigeria, the FAW had a negative impact on income and food production among farming households, resulting in millions of dollars being lost (Abiodun et al, 2020). Similarly, Tambo et al (2021) revealed that in Zimbabwe FAW positively impacted household food shortage and decreased per capita income.…”

PurposeThe paper aims to examine fall armyworm's (FAW) effect on Ghana's farming households' income and food security status.Design/methodology/approachA sample of 225 farmers, including FAW-infested households and non-FAW-infested households, were interviewed. Gross margin (GM) analysis was used to estimate farmers' farm revenues, and the Household Food Insecurity Access Scores (HFIAS) was employed to measure the food security status of the households. The seemingly unrelated regression (SUR) was adopted to investigate the effect of FAW infestation on gross income and food security.FindingsFrom the study, FAW attack is predominant during the vegetative stage of the maize plant. The empirical results revealed that FAW-infested farms incur loss, whereas non-FAW-infested farmers gained profit. Also, FAW-infested households were mildly food insecure, while non-FAW-infested households were food secured. The results of SUR analysis reveal that FAW infestation decreased farmers' income from maize production and rendered them food insecure.Research limitations/implicationsOne limitation of this study is that it largely depended on a survey; however, future studies can combine both survey and experimental data from the farmers' fields during minor and major growing seasons of maize.Originality/valueGiven the negative consequences of FAW, studies have been conducted across Africa and globally. However, most of these studies concentrated on using geographic information system (GIS) and descriptive statistics without necessarily quantifying the effect of FAW on food security and the profit margins of farming households. Therefore, this study adds to the little literature on the effect of FAW on food security and GM from maize production, which has received less attention in Ghana to the authors' best knowledge.
