This handbook is a companion to Agricultural Insect Pests of the Tropics and their Control (2nd Edition 1983) and, like the earlier book, it is designed as a source of reference about most of the major insect and mite pests of agricultural crops. These two volumes by the same author now present a world-wide coverage of the economically important insect pests of tropical and temperate agriculture. Students taking courses in entomology, agriculture, crop pest biology and crop protection, and professional workers concerned with identification and control of insect pests, will find this comprehensive account an indispensable handbook and source of reference.
Planning insecticide evaluation studies. Rearing of test insects. Determining LD50 values of insecticides. Insectary evaluation of insecticides. Field evaluation of insecticides. Physical assessment of spraying systems. Sampling insect populations and estimating insect damage in field experiments. Statistical analysis of insect populations and plant damage. Data reporting and making insect control recommendations.
Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.
Insects, mites, and ticks have a long history of evolving resistance to pesticides, host-plant resistance, crop rotation, pathogens, and parasitoids. Insect resistance management (IRM) is the scientific approach to preventing or delaying pest evolution and its negative impacts on agriculture, public health, and veterinary issues. This book provides entomologists, pest management practitioners, developers of new technologies, and regulators with information about the many kinds of pest resistance including behavioral and phenological resistance. Abstract concepts and various case studies provide the reader with the biological and economic knowledge required to manage resistance. No other source has the breadth of coverage of this book: genomics to economics, transgenic insecticidal crops, insecticides, and other pest management tactics such as crop rotation. Dr. David W. Onstad and a team of experts illustrate how IRM becomes efficient, effective and socially acceptable when local, social and economic aspects of the system are considered. Historical lessons are highlighted with new perspectives emphasized, so that future research and management may be informed by past experience, but not constrained by it.* First book in 15 years to provide the history and explore aspects of a variety of stakeholders* Contributors include experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues* Biochemistry and molecular genetics of insecticides presented with an mphasis on past 15 years of research including Cry proteins in transgenic crops* Encourages scientists and stakeholders to implement and coordinate strategies based on local social conditions
