Information accumulates from direct observations, scientific literature, and anecdotes from others. Information from these sources blurs together quickly, and consequently, unique ideas are rare in society. Credit for sources of information on urban pest control and management must go to:
| Land Grant University Extension and research workers, most entomologists, who pioneered this work, those who kept training and research alive during the period when the success of synthetic organic pesticides preempted nearly all but control evaluations from the 1940s to the 1960s, and those who persist today; |
| Pest Control Industry workers who held training sessions nationally, regionally, and locally where information was disseminated among the experienced and provided to the inexperienced; |
| Environmental Protection Agency personnel who molded modern training and influenced the need for national uniformity in training requirements; |
| State regulatory personnel who cooperated with Universities and Industry and who strongly emphasized the importance of training; |
| The few textbook authors in the United States and England who compiled the reference data in the understandable and usable form that allows urban pest management practitioners to be professionals. |
Specific acknowledgements should go to biological illustrators who graphically render pest and beneficial animals where photographs fail; A.D. Cushman, Dean of USDA illustrators, A. B. Wright, and Joseph Papp provided many illustrations for these modules as did many anonymous illustrators whose work was stripped of identification through the decades of public use. Likewise, heartfelt credit must go to photographers who provide the illustrative color slides so important to training sessions. Slides used in this publication were provided by N. Briesch, University of Maryland; A. Greene, GSA; R.T. Lubbert, National Institutes of Health, J. Sargent, Great Lakes Chemicals; N. Swink, U.S. Fish and Wildlife Service; and the Fish and Wildlife Service, Audiovisual Office. And like all else, many other slides were provided by colleagues whose generosity goes unrewarded.
Individuals who were vitally helpful in the production of these training modules include Elaine Mesavage, University of Maryland Entomology Department; Robert Gillette, DUAL & Associates, Inc.; Robert Bielarski, Environmental Protection Agency; Lawrence J. Pinto, Pinto and Associates, Inc., who wrote the Vertebrate Module; and finally, Jann Cox, DUAL & Associates, Inc., whose abilities as technical and format editor were responsible for evaluating and bringing all of the information together in usable form.
