Connecting aflatoxin risk to control of ear-feeding insects by Bt-corn is challenging. Our evidence for highlighting the importance of this connection comes from field studies measuring ear injury and aflatoxin across multiple years, locations, and hybrid backgrounds. These data are supplemented by recent observations on stage specific mortality of H. zea on silks and kernels of selected corn hybrids.
