Abstract Rice ( Oryza sativa L.), a primary staple food for billions of people worldwide, faces growing threat from the invasive fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), in Asia. Given predominance small-scale farmers Asian rice production, which accounts over two-thirds global output, region is highly vulnerable to FAW infestations. The FAW’s rapid reproduction, extensive dispersal capabilities, and remarkable adaptability pose significant risks, with potential substantial yield losses comparable those observed other crops. Recent reports highlight concerning host shift corn-specialized strain towards cultivation Beyond direct losses, infestations can lead excessive use pesticides, posing serious threats human health environment safety. Effective sustainable management crucial ensuring long-term agricultural sustainability. Control strategies encompass diverse range approaches, including cultural techniques, biological methods, chemical interventions, habitat manipulation. absence varieties resistant underscores urgent need accelerated development through genetic engineering. Cultural control practices, such as staggered planting, deep tillage, crop rotation non-host species, improved field sanitation, effectively reduce populations. While promising, methods like trap cropping push-pull require further validation systems. Biological measures utilize natural predators, big-eyed bugs ground beetles, parasitoids Telenomus remus Campoletis sonorensis . Additionally, entomopathogenic agents Metarhizium rileyi , Bacillus thuringiensis (Bt), Beauveria bassiana offer environmentally alternatives insecticides. synthetic insecticides remain an essential component management, increasing prevalence pesticide resistance associated economic necessitate eco-friendly solutions. multiple insecticide classes robust strategies. This review emphasizes critical role integrated pest (IPM) combating Asia, advocating balanced approach that prioritises control, effective judicious insecticides, mitigate damage ensure security region.
