The use of remote sensing to detect herbivory levels has increasing utility in a wide variety of agricultural systems, and may prove to be a powerful tool with which to test insect population models and insect management techniques. Here we present preliminary evidence based on 2004 growing season research that airborne imagery can be used to distinguish Bt corn from conventional corn and detect areas of pest infestation. The use of remote imagery may be a cost-effective way to monitor the >20 million acres of Bt corn for the detection of pests resistant to the pesticidal crop trait.
