Providing clear examples of the use of state-of-the-art computer programs for analyses of bioassay data, Bioassays with Arthropods, Second Edition explains the statistical basis and analysis for each kind of quantal response bioassay. The first edition was a must-have reference for designing, conducting, and interpreting bioassays: this comp

Imagine a statistics book for bioassays written by a statistician. Next, imagine a statistics book for bioassays written for a layman. Bioassays with Arthropods, Third Edition offers the best of both worlds by translating the terse, precise language of the statistician into language used by the laboratory scientist. The book explains the statistical basis and analysis for each kind of quantal response bioassay in just the right amount of detail. The first two editions were a great reference for designing, conducting, and interpreting bioassays: this completely revised and updated third edition will also train the laboratory scientist to be an expert in estimation of dose response curves. New in the Third Edition: Introduces four new Windows and Apple-based computer programs (PoloJR, OptiDose, PoloMixture and PoloMulti) for the analyses of binary and multiple response analyses, respectively Replaces out-of-date GLIM examples with R program samples Includes a new chapter, Population Toxicology, and takes a systems approach to bioassays Expands the coverage of invasive species and quarantine statistics Building on the foundation set by the much-cited first two editions, the authors clearly delineate applications and ideas that are exceptionally challenging for those not already familiar with their use. They lead you through the methods with such ease and organization, that you suddenly find yourself readily able to apply concepts that you never thought you would understand.

Pesticide Bioassays with Arthropods is written specifically to explain the statistical bases and analyses of quantal-response bioassays in entertaining yet succinct terms that scientists can understand.

Pesticide: susceptibility. Influelnces. Resistance management.

Written by experts in the fields of insect pest genetics, the genetics of biological control organisms, and the application of biological control, this book provides the first up-to-date summary of the genetic literature on the genetics of arthropod biological control agents. It identifies successful programs and also gaps and needs in research, research constraints, and possible research approaches in this important field of pest control. The power and applicability of new genetic and molecular biology methods have created new and exciting possibilities to greatly improve the effectiveness of traditional biological control programs. This book provides essential information about the state-of-the-art application of these new methods. It explains how biological control procedures can be improved, covers methods for selecting pesticide-resistant strains of natural enemies, and looks at methods for maintaining genetic diversity and quality control during the rearing of biological control agents in the laboratory. The book also provides information regarding the application of powerful PCR methods for taxonomic identification of strains and species of biocontrol agents.

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.
