The global spread of Fall Armyworm (FAW, Spodoptera frugiperda) has posed significant challenges to crop productivity and food security, with current pest management relying heavily on synthetic pesticides. This study explores the green synthesis neem extract oil-based Azadirachtin nanopesticides using cellulose acetate (CA) as a carrier polymer, focusing their efficacy against FAW. objective was assess whether CA-NEP (neem nanopesticides) CA-NOL oil nanopesticide) formulations were effective at FAW control minimal ecological impact. synthesized by electrospinning concentrations 5 %, 10 20 33 50 % (w/w) characterized Scanning Electron Microscopy Fourier Transform Infrared spectroscopy. content quantified Liquid Chromatography-Mass Spectroscopy. followed first-order, Korsmeyer-Peppas release kinetics, respectively. Feeding bioassays showed high mortality rates, %-50 achieving greater than 40 in less 3 days reaching 100 day five. rates due feeding CA-NOL-treated corn leaves reached after 4 6 days, respectively, for CA-NOL. Placing nanopesticide fibers next seeds during planting significantly reduced leaf damage. lethal dose (LD50) analyses that 13 is optimal concentration control. Environmental safety assessments earthworms no acute or chronic toxicity, indicating suit ecologically sensitive areas. Therefore, these provide promising, eco-friendly alternative sustainable enhanced safety.
