Available in PDF, EPUB and Kindle. Book excerpt: Bruce E. Tabashnik and Richard T. Roush Pesticide resistance is an increasingly urgent worldwide problem. Resistance to one or more pesticides has been documented in more than 440 species of insects and mites. Resistance in vectors of human dise8se, particularly malaria-transmit ting mosquitoes, is a serious threat to public health in many nations. Agricultural productivity is jeopardized because of widespread resistance in crop and livestock pests. Serious resistance problems are also evident in pests of the urban environ ment, most notably cockroaches. Better understanding of pesticide resistance is needed to devise techniques for managing resistance (Le. , slowing, preventing, or reversing development of resistance in pests and promoting it in beneficial natural enemies). At the same time, resistance is a dramatic example of evolution. Knowledge of resistance can thus provide fundamental insights into evolution, genetics, physiology, and ecology. Resistance management can help to reduce the harmful effects of pesticides by decreasing rates of pesticide use and prolonging the efficacy of environmentally safe pesticides. In response to resistance problems, the concentration or frequency of pesticide applications is often increased. Effective resistance management would reduce this type of increased pesticide use. Improved monitoring of resis tance would also decrease the number of ineffective pesticide applications that are made when a resistance problem exists but has not been diagnosed. Resistance often leads to replacement of one pesticide with another that is more expensive and less compatible with alternative controls.

This book was released on 2013-11-11 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1989 Annual Meeting of the Society for Risk Analysis dramatically demonstrated one of the most important reasons for having the Society - to bring together people with highly diverse backgrounds and disciplines to assess the common problems of societal and individual risks. The physical scientists emphasized the analytical tools for assessing environmental effects and for modeling risks from engineered systems and other human activities. The health scientists presented numerous methods of analyzing health effects, including the subject of dose-response relationships, especially at low exposure levels - never an easy analysis. The social and political scientists concentrated on issues of risk perception, communication, acceptability, and human touch. Others discussed such issues as cost-benefit analysis and the risk-based approach to decision analysis. Use of risk assessment methods for risk management continued to be a matter of strong opinion and debate. The impacts of state and federal regulations, existing and planned, were assessed in sessions and in luncheon speeches. These impacts show that risk analysis practitioners will have an increasingly important role in the future. They will be challenged to provide clear, easily understood evaluations of risk that are responsive to society's concern for risk, as evidenced in laws and regulations. Of course, the various risk analysis specialties overlapped in domains of interest.
