2006 Annual Report 4d.Progress report. This report serves to document research conducted under a Specific Cooperative Agreement between ARS and The Ohio State University. Additional details of research can be found in the report for the parent CRIS 3607-21620-006-00D Biological, Microclimate, and Transport Processes Affecting Pest Control Application Technology. Emerald Ash Borer (EAB) was officially identified in southeastern Michigan in the summer of 2002. It has killed at least 8 to 10 million ash trees in Michigan, Ohio and Indiana, costing municipalities, property owners, nursery operators and forest products industries tens of millions of dollars. It is extremely difficult to determine whether an ash tree is infested with EAB because tree decline is usually gradual. Since the EAB is new to North America, treatment techniques are needed to eliminate this exotic pest and prevent further spread. With regard to the control of the EAB, knowledge about the behavior and movement of this pest in and around trees is incomplete. Data are needed on EAB behavior to aid development of treatment and management strategies and enable more effectively schedule and target control measures. Entomological radar technology offers potential for adapting or developing tools for investigating insect behavior, populations or migration. The objective of this project will be to develop a microwave inset tracking system (or harmonic radar tracking system) containing a small, light-weight radio frequency tags and user-friendly transmitter and receiver for the emerald ash borer and black vine weevil insects, to clarify their dispersal and behavioral patterns that are incompletely understood and for which few or even conflicting data are available.
