This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science and technology are cultural phenomena. Expert knowledge is generated amid the conflicts of a society and in turn supplies fuel to fire yet further change and new clashes. This essay on economic entomology is a case study on how cultural events and forces affected the creation of scientific and technical knowledge. The time period emphasized is 1945 to 1980. My initial premises for selecting relevant data for the story were ultimately not of much use. Virtually all debates about insect control since 1945 have been centered around the environmental and health hazards associated with insecticides. My first but inadequate conclusion was that the center of interest lay between those who defended the chemicals and those who advocated the use of nonchemical control methods. With this formulation of the problem, I was drawn to an analysis of how the chemical manufacturers had managed to dominate and even corrupt the work of entomological scientists, farmers, members of Congress, and regulators in the USDA and EPA. My own contribu tions to a policy study at the National Academy of Sciences were based 1 on this premise. More recently, Robert van den Bosch developed the 2 "corruption theme" in considerable detail.

Available in PDF, EPUB and Kindle. Book excerpt: The Theory and Practice of Biological Control covers conventional biological control achievement in the major crop types and in public health problems. Composed of five sections encompassing 28 chapters, this book discusses the basic information concerning developments in other biologically based alternatives to chemical pesticides. The first two sections discuss the philosophy, theory, scope, history, and the biological and ecological bases of biological control. These sections also deal with the impact of predators and the host relationships of parasitoids and pathogens. The following section presents the methodological aspects of biological control. Discussions on the variability of natural enemies as encountered in biological control work; the fitness of individuals and populations; the ways fitness is being or can be influenced by importation procedures; and the ability of imported natural enemies to adapt to the new environment are included. The fourth section outlines the accomplishments of conventional biological control in various types of crops, forests, and public health areas. Lastly, the various components of integrated pest control other than conventional biological control that forms the essential ways used in the integrated control approach are covered in the last section of the book. This book is an ideal source for plant pathologists and researchers, microbiologists, parasitologists, and public health professionals.
