Abstract

Field studies were conducted to determine the efficacy of single trait Bt corn product (Bt11xGA21) against the Asian corn borer, ostrinia furcanalis (Guenee). The studies were set up in two sites, namely: Barangay Carabatan Punta, Cauayan, Isabela and Barangay San Isidro, General Santos City, South Catobato, Philippines, at vegetative and reproductive stages of corn, for two seasons (dry and wet), and with artificial and natural infestation of Asian corn borer. No Asian corn borer survived on Bt corn (Bt11xGA21) during both vegetative and reproductive stages in both trial locations while survival of Asian corn borer on non-Bt (GA21) corn was consistently higher during reproductive stage of corn in both sites. Therefore, Bt maize, Bt11xGA21, remains highly efficacious against the Asian corn borer up to the present, since its commercial launch in the Philippines, a decade back.
