The emerald ash borer, (EAB), Agrilus planipennis Fairmaire, a buprestid wood borer, was discovered infesting and killing trees in the area of Detroit, Michigan, in June of 2002. It was subsequently discovered in Essex Co., Ontario, in August. Surveys now indicate that 13 Michigan counties encompassing greater than 2,500 square miles are now generally infested. A number of isolated small populations have also been found in Michigan, Indiana, Ohio, Maryland, and Virginia. Most of these are thought to be the result of movement of infested nursery stock, logs, or firewood. Potential impacts of this insect, if allowed to spread, are substantial. In the U.S. alone, there are over 700 million ash trees, and a U.S. Forest Service report estimated the loss from EAB at between 20 and 60 billion dollars. In response to the discovery of these wood borer populations, federal, state, and local authorities held a number of meetings and prepared risk assessments. Both the Canadian and the United States version of the risk assessments conclude that substantial impacts would be the result of this introduction unless actions are undertaken to mitigate them. A Respective Science Panel was convened in each affected country, and their reports have similar recommendations: to develop a plan to contain and, eventually, eliminate emerald ash borer (EAB) populations in both countries. The plans are based on a zone management concept, including extensive survey efforts. The U.S. Science Panel also recommended that a strong commitment be made to developing the scientific information and technology necessary to carry out any management programs. A list of areas where research was critically needed was also developed.

As funding from various sources became available for EAB technology development and research, a number of federal, state, provincial and university groups became involved in the work. The meeting in Romulus was the second effort to pull together the many scientists involved in the work in a forum in which they could detail their interest and share their preliminary findings. The goal of the meeting was to identify areas of common interest, coordinate existing efforts, minimize duplication, and identify critical areas not being addressed. The abstracts contained in this report represent a robust response by the scientific community to the challenges offered by this exotic pest. In the future, it is hoped that this response will be sufficient to address the EAB problem, and help prepare the land managers and scientific community for other invasions.

Most of the abstracts were submitted in an electronic format, and were edited to achieve a uniform format and typeface. Each contributor is responsible for the accuracy and content of his or her own paper. Statements of the contributors from outside of the U.S. Department of Agriculture may not necessarily reflect the policy of the Department. Some participants did not submit abstracts, and so their presentations are not represented here.

Remarks about pesticides appear in some technical papers represented by these abstracts. Publication of these statements does not constitute endorsement or recommendation of them by the conference sponsors, nor does it imply that uses discussed have been registered. Use of most pesticides is regulated by state and federal laws. Applicable regulations must be obtained from the appropriate regulatory agency prior to their use. CAUTION: Pesticides can be injurious to humans, domestic animals, desirable plants, and fish and other wildlife if they are not handled and applied properly. Use all pesticides selectively and carefully. Follow recommended practices given on the label for use and disposal of pesticides and pesticide containers.
