Objectives: Monitoring European Corn Borer (ECB) infestations at the time of infestation is difficult to accomplish. Scouting for egg masses is time consuming, expensive, and must be conducted within a short, specific period of time for both ECB generations. A better method for monitoring needs to be developed that is quick, relatively cheap, efficient, and non-invasive to the corn plants. One potential insect monitoring tool may be the radiometer. This equipment is currently being used from both ground and satellite stations to measure changes in water content, energy flow, and other parameters of various field crops.
The object of this study is to determine if first and second generation ECB infestations can be detected using a field radiometer. If ECB infestations are detectable, radiometer measurements will be compared from first and second generation larvae and from infested and noninfested Bt and non-Bt corn isolines.
