Most Lepidoptera disperse as adults, but in some groups the larvae disperse as well. Larval dispersal takes the form of ballooning; larvae use silk to hang off of plant surfaces and some get picked up by the wind. The longer the silk length, the greater the drag and the more likely the larva is to get picked up by the wind and the farther the larva will travel. The European corn borer (ECB), Ostrinia nubilalis, has been observed ballooning and is currently the target of a large control effort using transgenic Bt corn. I examined the differences between ECB larval dispersal on Pioneer 34K78 Mon 810 event Bt corn and Pioneer 34K77 non-Bt isoline corn. I tested plant abandonment, larval dispersal in artificial plots and ECB silking behavior. My results suggest that ECB larvae that hatch on a Bt corn plant abandon that plant with a higher frequency than ECB larvae that hatch on a non Bt corn plant and that ECB larvae are capable of reaching neighboring corn plants by ballooning. This dispersal behavior may play a significant role in resistance management, particularly in the spacing of non-Bt refuges. These experiments help us to better understand ECB neonate behavior and may apply to other insects under Bt selection pressure.
