Efficacy Testing of Nuclear Polyhedrosis Virus (NPV) Against Fall Army Worm [Spodoptera frugiperda (J.E. Smith)]

Author(s) Ms. April Hope Espital Panis, Prof. Dr. Agnes Simene Riñon
Country Philippines
Abstract Fall Army Worm (Spodoptera frugiperda) is identified as one of the most destructive insect pests of corn, affecting corn production in the Philippines, particularly in Bukidnon. The rapid spread of Fall Army Worm and its increasing resistance to synthetic insecticides have created serious concerns about crop losses, environmental safety, and sustainable pest management. This study aims to (1) determine the most effective concentration of NPV for the control of FAW, and (2) assess the extent of damage on corn as affected by different NPV concentrations. It was conducted at the Northern Mindanao Agricultural Crops and Livestock Research Complex (NMACLRC), Dalwangan, Malaybalay City, Bukidnon. The Results confirmed that NPV at a high concentration of 21 larvae/16 L of water recorded the highest larval mortality and the lowest leaf damage rating, while the control treatment recorded the lowest mortality and the highest damage rating, indicating severe damage. The study concluded that NPV strains applied at higher concentrations are effective, environmentally safe, and sustainable biological control agents for managing fall army worm in corn production systems in Bukidnon.
