OUR FORESTS ARE LIMITED RESOURCES,
valuable for recreation, soil and water management, and timber. Thus, control of various forest pests is receiving increased attention. The chapters in this volume examine the state of the art of the development of effective chemical and biological agents, as well as the unique application problems not encountered in conventional agricultural situations. The effectiveness of pesticides or pheromone technology in com bating forest pests is not the only determinant. Factors peculiar to the forest situation, including the delicate balance of the ecosystem, must be considered in both the development and application stages of all control tactics. We have attempted to highlight the major components involved in forestry pest management: Control Agents; Spray Deposition; Target and Nontarget Residue Distribution; and Ecotoxicology and Hazard Assessment. We believe we have covered most aspects. We wish to thank all the authors for their participation in the sympo sium and their contributions to this volume. Our special thanks go to Illo Gauditz for her never-failing interest, advice, and cooperation in putting the symposium together.
