Remote-sensing studies were conducted with Bt and non-Bt corn plots in Iowa, Pennsylvania and Nebraska during 2004 and 2005. Hyperspectral bands of reflected radiation from vegetation and ground were measured seven times over the growing season with an aircraft-mounted hyperspectral imaging push-broom scanner. Treatments included Bt and non-Bt corn hybrids some of which were infested with Ostrinia nubilalis (Hübner) neonates during V8-V10 or silking stages. Preliminary results suggest that specific spectral bands can distinguish plots with O. nubilalis damage from those that were undamaged. Reflectance images from different hybrids also were distinguishable, but these differences varied with crop phenology.
