Book Description
Feeding on Non-Prey Resources by Natural Enemies Moshe Coll Reports on the consumption of non-prey food sources, particularly plant materials, by predators and parasitoids are common throughout the literature (reviewed recently by Naranjo and Gibson 1996, Coll 1998a, Coll and Guershon, 2002). Predators belonging to a variety of orders and families are known to feed on pollen and nectar, and adult parasitoids acquire nutrients from honeydew and floral and extrafloral nectar. A recent publication by Wäckers et al. (2005) discusses the p- visioning of plant resources to natural enemies from the perspective of the plant, exploring the evolutionary possibility that plants enhance their defenses by recru- ing enemies to food sources. The present volume, in contrast, presents primarily the enemies’ perspective, and as such is the first comprehensive review of the nut- tional importance of non-prey foods for insect predators and parasitoids. Although the ecological significance of feeding on non-prey foods has long been underappreciated, attempts have been made to manipulate nectar and pollen ava- ability in crop fields in order to enhance levels of biological pest control by natural enemies (van Emden, 1965; Hagen, 1986; Coll, 1998a). The importance of n- prey foods for the management of pest populations is also discussed in the book.

Book Description
Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

Book Description
Over the past three decades there has been a dramatic increase in theoretical and practical studies on insect natural enemies. The appeal of insect predators, and parasitoids in particular, as research animals derives from the relative ease with which many species may be cultured and experimented with in the laboratory, the simple life cycles of most parasitoids, and the increasing demand for biological pest control. There is now a massive literature on insect natural enemies, so there is a great need for a general text that the enquiring student or research worker can use in deciding on approaches and techniques that are appropriate to the study and evaluation of such insects. This book fulfils that demand. A considerably updated and expanded version of a previous best-seller, it is an account of major aspects of the biology of predators and parasitoids, punctuated with information and advice on which experiments or observations to conduct, and how to carry them out. Guidance is provided, where necessary, on the literature that may need to be consulted on particular topics. While researchers can now refer to several books on parasitoids and predators, Insects as Natural Enemies is unique in emphasising practicalities. It is aimed at students and professional working in universities and both government and commercial institutes in the fields of pest management, agriculture, horticulture and forestry.

Book Description
This book is about disease and death. It is an ecologist's view of Darwin's vivid evocation of Nature, red in tooth and claw. An international team of authors examines broad patterns in the population biology of natural enemies, and addresses general questions about the role of natural enemies in the population dynamics and evolution of their prey. For instance, how do large natural enemies like wolves differ from small natural enemies like bacterial diseases in their effects on prey abundance? Is it better to chase after prey, or sit and wait for it to come to you? How should prey behave in order to minimize the risk of being eaten? The answers are all in this fascinating senior undergraduate/postgraduate text.

Book Description
Carnivores provide innumerable ecological benefits and play a unique role in preserving and maintaining ecosystem services and function, but at the same time they can create serious problems for human populations. A key question for conservation biologists and wildlife managers is how to manage the world's carnivore populations to conserve this important natural resource while mitigating harmful impacts on humans. In People and Predators, leading scientists and researchers offer case studies of human-carnivore conflicts in a variety of landscapes, including rural, urban, and political. The book covers a diverse range of taxa, geographic regions, and conflict scenarios, with each chapter dealing with a specific facet of human-carnivore interactions and offering practical, concrete approaches to resolving the conflict under consideration. Chapters provide background on particular problems and describe how challenges have been met or what research or tools are still needed to resolve the conflicts. People and Predators will helps readers to better understand issues of carnivore conservation in the 21st century, and provides practical tools for resolving many of the problems that stand between us and a future in which carnivores fulfill their historic ecological roles.

Book Description
This book provides the first coherent examination of the vast literature on the diversity of organisms that constitute the natural enemies of terrestrial molluscs. In a series of review chapters, it provides an authoritative synthesis of current research on predators, parasites and pathogens and how they might be used to control mollusc pests.

Book Description
Biological control – utilizing a population of natural enemies to seasonally or permanently suppress pests – is not a new concept. The cottony cushion scale, which nearly destroyed the citrus industry of California, was controlled by an introduced predatory insect in the 1880s. Accelerated invasions by insects and spread of weedy non-native plants in the last century have increased the need for the use of biological control. Use of carefully chosen natural enemies has become a major tool for the protection of natural ecosystems, biodiversity and agricultural and urban environments. This book offers a multifaceted yet integrated discussion on two major applications of biological control: permanent control of invasive insects and plants at the landscape level and temporary suppression of both native and exotic pests in farms, tree plantations, and greenhouses. Written by leading international experts in the field, the text discusses control of invasive species and the role of natural enemies in pest management. This book is essential reading for courses on Invasive Species, Pest Management, and Crop Protection. It is an invaluable reference book for biocontrol professionals, restorationists, agriculturalists, and wildlife biologists.
