Assessing Regional Risks and Policy Responses to Fall Armyworm (Spodoptera frugiperda) Invasion in Davao Region

Abstract

The fall armyworm (FAW), Spodoptera frugiperda, has emerged as a serious threat to rice and corn production in the Philippines, particularly in the Davao Region. Since its detection in 2019, the pest has rapidly spread due to its high mobility, polyphagous feeding behavior, and adaptability, causing significant crop damage and threatening regional food security and farmer livelihoods. Corn, being the pest’s preferred host, has suffered yield losses of up to 80% in severe infestations, while recent reports also confirm its ability to attack rice seedlings. The region’s diverse cropping systems, continuous cultivation, and favorable climate further increase FAW’s establishment and spread. Current responses rely heavily on chemical control, raising concerns over resistance development, environmental harm, and health risks. This policy brief therefore advocates the urgent adoption of science-based, integrated pest management strategies, strengthening surveillance and monitoring systems, promoting resilient, diversified farming practices, and enhancing farmer education and extension support. It also recommends increased research funding, stakeholder collaboration, and participatory approaches to develop locally adapted solutions. Implementing these coordinated strategies will reduce FAW impacts, safeguard rice and corn production, and support the long-term resilience and sustainability of the agricultural sector in the Davao Region.
