Download or read book The Fire Ant Wars written by Joshua Blu Buhs and published by University of Chicago Press. This book was released on 2010-11-15 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sometime in the first half of the twentieth century, a coterie of fire ants came ashore from South American ships docked in Mobile, Alabama. Fanning out across the region, the fire ants invaded the South, damaging crops, harassing game animals, and hindering harvesting methods. Responding to a collective call from southerners to eliminate these invasive pests, the U.S. Department of Agriculture developed a campaign that not only failed to eradicate the fire ants but left a wake of dead wildlife, sickened cattle, and public protest. With political intrigue, environmental tragedy, and such figures as Rachel Carson and E. O. Wilson, The Fire Ant Wars is a grippingly perceptive tale of changing social attitudes and scientific practices. Tracing the political and scientific eradication campaigns, Joshua Buhs's bracing study uses the saga as a means to consider twentieth-century American concepts of nature and environmental stewardship. In telling the story, Buhs explores how human concepts of nature evolve and how these ideas affect the natural and social worlds. Spotlighting a particular issue to discuss larger questions of science, public perceptions, and public policy—from pre-environmental awareness to the activist years of the early environmental movement—The Fire Ant Wars will appeal to historians of science, environmentalists, and biologists alike.

Book excerpt: Plant Diseases: Epidemics and Control provides a description of the methods of epidemiological analysis based on infection rates and the relation between the amount of inoculum and the amount of disease it produces. The book shows how to study the increase of pathogen populations and the epidemiological strategy to be adopted to control the epidemic of plant diseases. The text covers the calculation of the logarithmic increase of disease; use of epidemiology in the study of control; forms of sanitation; the use of resistant plant varieties; and the design of field experiments. Plant pathologists and breeders, agriculturists, horticulturists, research workers, teachers, and students will find the text invaluable.
