Asian corn borer (<scp>ACB</scp>) and non‐<scp>ACB</scp> pests in <scp>GM</scp> corn (<i>Zea mays</i> L.) in the Philippines

Abstract

Bt and BtHT corn hybrids containing the Cry1Ab protein performed well in Isabela Province. Reduced cob damage by ACB on Bt fields could mean smaller economic losses even with ACB infestation. The occurrence of ACB in Bt and BtHT cornfields, although at a moderate and insignificant level, could imply the potential development of resistance to Bt toxin.
