Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Evidence that a major subpopulation of fall armyworm found in the Western Hemisphere is rare or absent in Africa, which may limit the range of crops at risk of infestation.

PLoS ONE, 2019
The introduction and establishment of fall armyworm (Spodoptera frugiperda) in Africa presents a major threat to agriculture in that continent and potentially to the entire Eastern Hemisphere.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Artificial exposure to herbivore‐induced volatile organic compounds reduces herbivory and modulates gene expression in potato plants

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings provide strong mechanistic evidence for VOCs mediating pest resistance and suggest that exposure to herbivore‐induced, plant‐derived VOCs can enhance pest resistance in potato crops. These results might offer novel information for developing ecologically sustainable plant volatile‐based strategies for boosting protection against pests in

Development of PCR, LAMP and HRM‐Based Molecular Species Diagnostic Tools for Identifying Four Agricultural Pests in the Genus Helicoverpa (Lepidoptera: Noctuidae)

Journal of Applied Entomology, Volume 150, Issue 7, Page 900-913, August 2026.
ABSTRACT Within the subfamily Heliothinae, the genus Helicoverpa comprises several highly destructive agricultural pests, including H. armigera, H. assulta, H. punctigera and H. zea. These species cause significant global crop losses due to their wide host range, long‐distance migratory behaviour, and potential for interspecific hybridization.

Exploring Newer Molecules With Novel Modes of Action For The Management of The Invasive Maize Fall Armyworm, Spodoptera frugiperda (J.E. Smith) [PDF]

Madras Agricultural Journal
Maize is affected by more than 30 insect pests and the recent attack by the invasive fall armyworm Spodoptera frugiperda has been a serious concern to maize growers all over the country. Being polyphagous with a wider host range, the pest necessitates

Agricultural inputs unevenly boost crop yields but consistently reduce biodiversity on Mount Kilimanjaro

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Crop productivity on Mount Kilimanjaro is shaped by interactions among climate, human capital and biodiversity. Labour capital strongly increased crop yields, whereas physical capital, particularly agrochemical inputs, reduced biodiversity without increasing yields.

Genetic characterization of fall armyworm infesting South Africa and India indicate recent introduction from a common source population.

PLoS ONE, 2019
The invasion of the Western Hemisphere native fall armyworm (Spodoptera frugiperda; J. E. Smith) (Lepidoptera: Noctuidae) into the Eastern Hemisphere has been notable for the rapidity and geographical breadth of new detections.
