The first incidence of suspected FAW in the Philippines was reported on June 20, 2019 at Piat, Cagayan. Morphological examination of the lone sample matched with the distinctive characters for S. frugiperda. Subsequent collections from other corn growing areas in Cagayan and Ilocos Norte yielded additional specimens for validation using molecular markers.

The National Crop Protection Center (NCPC) and Institute of Weed Science, Entomology and Plant Pathology (IWEP), College of Agriculture and Food Science, University of the Philippines Los Baños verified the identity of the specimens using the DNA barcode cytochrome c oxidase 1 (COI) gene and results revealed a significant hit of 100% identity with nucleotide sequences of S. frugiperda.

The Bureau of Plant Industry is currently coordinating/ implementing the National Fall Armyworm Action Plan, with the following activities: 1. Quarantine inspection and disinfestation at the ports (sea, air, land) 2. Cultural management strategies (seed treatment, synchronous planting, weed management, plow-under after harvest, intercropping, crop rotation) 3. Monitoring and detection (use of pheromone lures/traps) 4. Scouting and validation 5. Awareness and capability building (information dissemination, trainings, coordination with LGU partners, farmers and other stakeholders) 6. Use of biological control agents and lures 7. Use of organic and inorganic pesticides 8. Research and development
