Assessment of movement behavior of third instar European corn borer, Ostrinia nubilalis, on Bt corn

European corn borer (Ostrinia nubilalis) is a major economic pest of Zea mays L. The introduction of transgenic Bt corn has lead to a significant decrease in the damage and control costs associated with European corn borer. However, in attempts to better predict and implement resistance management strategies investigators need to better understand the movement and feeding behaviors of 3^rd instar European corn borer. In our experiment, plants were infested with 3^rd instars in an array of treatments designed to represent various combinations of adjacent Bt and non-Bt plants in a blended refuge. Larvae were recaptured after 72 hours to assess the amount of movement.
