Producing this work involved not only a team, but also numerous other workers and supporters. So, we thank them all and ask forgiveness if we have failed to mention them here. First and foremost, we thank the Pilot Test Program of the Agricultural Research Service, USDA, for recognizing the importance of systematics to alternative pest control programs and for providing the funds to undertake this project. The Animal and Plant Health Inspection Service, Plant Protection and Quarantine, also provided funding, for which we are grateful. We also appreciate the assistance and support of Douglass Miller, Manya B. Stoetzel, and Michael E. Schauff, the Research Leaders of the Systematic Entomology Laboratory during the development of this identification system. To our scientific illustrators, Jennifer E. Fairman, T. Britt Griswold, and Susan Grupp, as well as our data entry specialist, Elaine B. Jamison, we could not have completed this project without your unique contributions. Hence, words can’t express our appreciation for your assistance.
We especially thank our reviewers, Eric Fisher, David L. Hancock, Bernhard Merz and Gary Steck, for their critical comments, suggestions and corrections. Norman E. Woodley and Natalia Vandenberg of the Systematic Entomology Laboratory likewise are thanked for their contributions to the review process.
