Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Desert Corn Flea-Beetle In destroying its food plant, this beetle works from both ends, as it were, the adults attacking the plant above the ground and the larvae below the ground. The adults eat out the chlorophyll of the leaves, and when sufficiently numerous they cause the leaves to wilt. If feeding is long continued, new growing plants will be killed. AS the eggs are deposited below the surface of the ground, the larvae immediately begin feeding. Upon the roots, and soon the plant has quite a shallow root system that will not support it in a thrifty manner. The roots, after having been injured by the larvae, attempt to overcome this injury by sending out new laterals, as illustrated in figure 6, page 11, and then sometimes Slight windstorms will cause plants to blow over and lodge badly, thus further reducing the yield.

Available in PDF, EPUB and Kindle. Book excerpt: Garden pests plague everyone who has ever raised vegetables, from backyard gardener to professional horticulturists, farm managers, and agrobusiness professionals. The economic impacts of vegetable pests are enormous. To manage and minimize the adverse impacts of pests, it is important to identify exactly which pests are afflicting crops. The Handbook of Vegetable Pests is intended to assist anyone in need of an easy-to-use, and yet comprehensive, survey of all pests likely to be encountered in North America. This Handbook provides thorough identification guides, descriptions of pest life history, and pest management recommendations. The text is well illustrated with hundreds of easy-to-use line drawings, is cross-referenced to the professional and scientific literature, and includes color plates for ease of insect pest identification. Every gardener, horticulturalist, farm manager, and plant science professional should have this Handbook as a ready desk reference.Key Features* Identification guides list the major and minor pests of each crop family and provide distinguishing characteristics for each pest * Includes pest profiles that describe the appearance, life history, and management of various pests * Over 600 black and white line drawings and over 100 color images to further aid in identification* Detailed glossary provided to help with the definition of some of the less known terms

Available in PDF, EPUB and Kindle. Book excerpt: The present world population of about five billion and its projected growth cre ate enonnous pressures and demands for food and industrial raw materials. It is to crop plants, one of our precious few renewable resources, that we must look to meet most of these needs. Globally, about 88% of our caloric requirements and 90% of our protein ultimately derive from plant sources-ample evidence of their importance to humankind. Our survival will therefore continue to de pend on the world's largest and certainly most important industry: agriculture. Yet in spite of our long history of domestication and civilization, the number of crop species involved in sustaining human life is strictly limited: Essentially, some twenty-four crops protect us from starvation. To know these basic food crop plants-to study how they function and how their productivity may be improved--is the first step in solving the world food problem. The primary objectives in writing this book were to address this chal lenge and to review comprehensively the wealth of available yet scattered infor mation on food crop productivity and processing. Unlike several other texts and monographs in this field, the present work was intended to give, in a single volume, a quick, infonnative view of the various problems from field to table concerning the major food crops worldwide.

Book excerpt: Offering a complete accounting of the insects of North America, this handbook is an up-dated edition of the first handbook ever compiled in the history of American entomology. By using American Insects, A Handbook of the Insects of America North of Mexico, Second Edition, readers can quickly determine the taxonomic position of any species, genus, or higher taxon of insect known to occur in America and Canada. Every order, family, and genus is conveniently numbered and indexed, making this volume the only complete single source for all of the names of orders, families, and genera currently available. This book fills the need for an accurate way to identify, with the several hundred drawings and photos, the common insects of all orders. Now there is a tool available to those working without a major collection and library; and those who would like to have a general knowledge of insect life without becoming overwhelmed by the vast number of minute insect species. This usable guide provides sizes, shapes, color patterns and salient features of some species of each major family by pointing out those groups most likely to be encountered, including all North America pests. What's New in this Edition? Researchers in many orders use the results of cladistics, a new tool for determining the relationship of orders, families, genera, and species of organisms, including plants as well as animals Specialists have provided lengthy lists of generic changes Many of the identification keys have been revised by adding more illustrations and making sure all description terms are in the Glossary The bibliographies of each Order section have been updated to include all important works that have appeared since the original edition
