Book Description
Handbook of Soybean Insect Pests is the first book in a new series from the Entomological Society of America that examines pest management from all angles—magnifying practical field strategies for growers—and updates growers on the latest protection techniques—preventing needless crop loss as a result of outdated pest control procedures. Edited by Leon G. Higley and David J. Boethel, this book outlines fundamental approaches to soybean pest management that can aid in reducing crop damage and loss. It provides detailed descriptions of topics such as insect identification, life-history data, and management options. This comprehensive guide includes discussions on soybean ecology and physiology, soybean insect pests, predators and parasitoids, soybean pest management procedures, noninsect soybean pests, and insect management. Also included are 92 color photographs, 200 illustrations, a directory of resources for obtaining local information, and a glossary.

Book Description
Legumes are important for the diet of a significant part of the world's population; they are a good source of protein, carbohydrates, minerals and vitamins. The'importance of soybean'lies in the overall agriculture and trade and in its contribution to food supply. Soybean contains the highest protein content and has no cholesterol in comparison with conventional legume and animal food sources. Furthermore, soybean is a cheap source of food, and at the same time medicinal due to its genistein, photochemical, isoflavones content. Soybean has been found to be extremely helpful in the fight against heart disease, cancer and diabetes, among others. Soybean protein and calories are presently being used to prevent body wasting often associated with HIV. The importance of soybean nutrition intervention is amplified where medications are unavailable. Its economic potential inherent in a wide range of industrial uses can be harnessed to the benefit of smallholder soybean producers.

Book Description
A growing body of literature over the past two decades has examined how landscape composition and structure affect communities and processes in agroecosystems, including crop pests and their natural enemies. A few general patterns have emerged: the diversity and abundance of natural enemies increases as noncrop habitat increases and landscapes have been found to have strong impacts on natural enemies' biological control ability. However, many relationships remain unclear. Improving models of landscape heterogeneity impacts on agricultural insect community abundance and composition could give more insight. Landscape characteristics are not the only factors impacting crop yields though. Temperature and precipitation are known to directly and indirectly affect insects in agroecosystems, and like landscapes, are heterogeneous across time and space. Thus my objectives were to determine the contribution of landscapes and abiotic factors to crop pest and natural enemy abundance in Wisconsin soybean fields and to assess the contribution of landscapes, abiotic factors, and pesticide use on ecosystem services, such as conservation biological control and crop yields, in Wisconsin soybean fields through impacts on crop pests and natural enemies. As a whole, this work contributes to our understanding of landscape context as a driver of insect abundance and function in agroecosystems, by incorporating alternate possibilities and potential covarying mechanisms. I was successful in tracing landscape effects to crop yields, as the first study we know of to accomplish this at field-scales. I found that both crop and noncrop habitats in the landscape support increased yields, as well as increased natural enemy occurrence and abundance in soybean fields. Yet the heterogeneous responses of specific taxa to landscape features, combined with the strong response of predator abundance and biological control potential assays to prey density, indicates that explicitly tracking resources within the growing season, rather than static annual metrics of land cover, may be a better way of understanding the contribution of landscapes. Additionally, soybean aphids appeared to benefit from increasing forest acreage in the landscape. Yet pest populations were more strongly correlated with abiotic factors, specifically precipitation and growing degree days, indicating that explicit inclusion of non-landscape factors is critical.

Book Description
This volume is a comprehensive treatment of how the principles of ecology and conservation biology can be used to maximize biological control. Conservation Biological Control presents various means to modify or manipulate the environment to enhance the activities of natural enemies of pests. It establishes a conceptual link between ecology and the agricultural use of agents for biological control, and discusses both theoretical issues as well as practical management concerns. Certain to be interesting to ecologists and entomologists, this volume will also appeal to scientists, faculty, researchers and students interested in pest management, horticulture, plant sciences, and agriculture. Contains chapters by an international team of leading authorities Establishes a conceptual link between ecology and the agricultural use of agents for biological control Discusses both theoretical issues as well as practical management concerns Provides specific examples of how conservation principles are used to maximize the biological control of pests

Book Description
Explore the latest research on biological control! Completely updated for 2004, this new edition examines methods for making agricultural systems less susceptible to insect pests. Containing new findings and reports of strategies, Biodiversity and Pest Management in Agroecosystems, Second Edition will show you how pests can be managed by enhancing beneficial biodiversity using agroecological diversification methods. Biodiversity and Pest Management in Agroecosystems, Second Edition provides you with an essential overview of the role of biodiversity in agriculture and then gets specific, with new and updated information on: the agroecology of pest management plant diversity and pest outbreaks within agroecosystems diversification strategies for pest management how sustainable farming systems are designed You'll also explore: the role of plant diversity on the biology of beneficial insects insect regulation in diverse agroecosystems manipulation of plant diversity in agroecosystems ecological and socioeconomic implications The fact is, many modern agroecosystems are unstable as a consequence of constant human intervention in crop systems which ignore ecological principles. With case studies on a variety of crops and pests, Biodiversity and Pest Management in Agroecosystems, Second Edition explores entomological aspects of agriculture and analyzes the ecological basis for the maintenance of biodiversity. It will familiarize you with the theory and practice of enhancing biological pest control in agricultural systems by managing vegetational diversity via multiple cropping, cover cropping, rotations, and other spatial and temporal designs. With studies on intercropping, cover cropping, weed management, and crop-field border vegetation manipulation, this book covers the effects of these diverse systems on pest population density and the mechanisms underlying pest reduction in polycultures.

Book Description
Integrated pest management (IPM) is a sustainable approach to manage pests through biological, cultural, physical and chemical means in order to minimize economic and environmental injury caused by such pests. Any comprehensive IPM programme requires an understanding of the ecological relationships between crops, pests, natural enemies and the environment. This book presents a series of review chapters on ecologically-based IPM. Topics covered range from the ecological effects of chemical control practices to the ecology of predator-prey and parasitoid-host systems.
