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.
We thank the authors of the abstracts for providing current information on emerald ash borer.
Thanks also to Mark Riffe, INTECS International, for format and design of this document, and
to FHTET for providing funding to print these abstracts.

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.
The use of trade, firm, or corporation names in this publication is for the information
and convenience of the reader. Such use does not constitute an official endorsement
or approval by the U.S. Department of Agriculture of any product or service to the
exclusion of others that may be suitable.
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.
