Resistance to conventional pesticides has been growing rapidly among all pests. Furthermore, there is increased public concern about the safety of conventional pesticides, and increased governmental restrictions have resulted in the need to identify new compounds that are safe and effective in controlling pests that are of concern to agriculture as well as to public and animal health. Biopesticides may aid in the control of such pests with fewer deleterious effects to the environment, people and animals. The U.S. Environmental Protection Agency (EPA) defines biopesticides as "pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals" (www.epa.gov). According to the U.S. EPA's website in 2014 there were more than 430 registered biopesticides along with 1320 active product registrations. Biopesticides have seen a recent growth, which is partially due to increased advances in biotechnological tools for pest control. However, the growth has been largely spurred by the growing needs for new tools to fight pesticide resistance and safer and more benign means of pest management. This volume and the chapters contained within it resulted from the "Biopesticides: State of the Art and Future Opportunities" symposium held at the 246th ACS National Meeting in Indianapolis, Indiana, September 8-12, 2013. The symposium was comprised of 38 papers in five sessions: The Big Picture, Repellents and Attractants, Insecticides and Nematicides, Products from Genetic Improvements, and Economic, Regulatory and Future Needs. Biopesticides: State of the Art and Future Opportunities offers a wealth of information that will enrich the knowledge of experts in the field of biopesticide research.

The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)

Pesticide use has changed considerably over the past five decades. Rapid growth characterized the first 20 years, ending in 1981. The total quantity of pesticides applied to the 21 crops analyzed grew from 196 million pounds of pesticide active ingredients in 1960 to 632 million pounds in 1981. Improvements in the types and modes of action of active ingredients applied along with small annual fluctuations resulted in a slight downward trend in pesticide use to 516 million pounds in 2008. These changes were driven by economic factors that determined crop and input prices and were influenced by pest pressures, environmental and weather conditions, crop acreages, agricultural practices (including adoption of genetically engineered crops), access to land-grant extension personnel and crop consultants, the cost-effectiveness of pesticides and other practices in protecting crop yields and quality, technological innovations in pest management systems/practices, and environmental and health regulations. Emerging pest management policy issues include the development of glyphosate-resistant weed populations associated with the large increase in glyphosate use since the late 1990s, the development of Bt-resistant western corn rootworm in some areas, and the arrival of invasive or exotic pest species, such as soybean aphid and soybean rust, which can influence pesticide use patterns and the development of Integrated Pest Management programs.
