GLASER, J. A. A NEW APPROACH TO PIP CROP MONITORING USING REMOTE SENSING. Presented at Third Workshop on Susceptability of Field Collected Lepidoptera to Bacillus thuringiensis Proteins in North America, Monterrey, MEXICO, October 05 - 08, 2006.
Description:
Current plantings of 25+ million acres of transgenic corn in the United States require a new approach to monitor this important crop for the development of pest resistance. Remote sensing by aerial or satellite images may provide a method of identifying transgenic pesticidal crop distribution in the landscape. Genetically engineered crops containing bacterial gene(s) that express an insecticidal protein from Bacillus thuringiensis (Bt) are regulated by EPA under the Federal Insecticide Fungicide and Rodenticide Act (FIFRA). Crops, containing transgenic pesticidal traits, have been recognized by EPA to be "in the public good," due to their potential to create higher crop yields with fewer insecticide applications. EPA requirements for FIFRA registration of transgenic pesticidal crops include a number of stewardship issues, among which crop monitoring for development of insect pest resistance plays a critical role. Using hyperspectral imagery collected from a camera mounted in a Cessna 210 aircraft; our research has imaged a series of designed corn plantings of known hybrid composition. The ability to distinguish transgenic hybrids from their nearest relative isolines and potentially determine differing levels of pest infestation detection will be discussed. Our evolving monitoring system is designed to provide an early warning of pest resistance development. It is important that crop management practices be adaptive to new threats and unexpected outcomes. The extension of current research into this system will also be discussed.
