Understanding invasion biology, and the dynamics of biological control practices, requires a multidisciplinary approach, embracing and integrating all the research tools at our disposal, particularly modern molecular and modelling techniques. This book provides a comprehensive and current overview of invasive alien arthropod predators and parasitoids through 20 chapters, contributed by 69 internationally renowned scientists (previously published as peer-reviewed papers in BioControl – August 2011), ranging from broad reviews of key topics on invasive alien species (IAS) to taxon-specific chapters. The context of invasion biology is given through nine chapters focusing on current themes but highlighting future directions and knowledge gaps. Concepts are explored in detail through ten chapters focusing on a taxonomically diverse range of arthropods. The concluding chapter presents an objective approach to considering the benefits and risks of exotic biological control agents.

This overview of the roles of alien species in insect conservation brings together information, evidence and examples from many parts of the world to illustrate their impacts (often severe, but in many cases poorly understood and unpredictable) as one of the primary drivers of species declines, ecological changes and biotic homogenisation. Both accidental and deliberate movements of species are involved, with alien invasive plants and insects the major groups of concern for their influences on native insects and their environments. Risk assessments, stimulated largely through fears of non-target impacts of classical biological control agents introduced for pest management, have provided valuable lessons for wider conservation biology. They emphasise the needs for effective biosecurity, risk avoidance and minimisation, and evaluation and management of alien invasive species as both major components of many insect species conservation programmes and harbingers of change in invaded communities. The spread of highly adaptable ecological generalist invasive species, which are commonly difficult to detect or monitor, can be linked to declines and losses of numerous localised ecologically specialised insects and disruptions to intricate ecological interactions and functions, and create novel interactions with far-reaching consequences for the receiving environments. Understanding invasion processes and predicting impacts of alien species on susceptible native insects is an important theme in practical insect conservation.

A wide-ranging, interdisciplinary exploration of key topics that interrelate pest management, public health and the environment This book takes a unique, multidimensional approach to addressing the complex issues surrounding pest management activities and their impacts on the environment and human health, and environmental effects on plant protection practices. It features contributions by a distinguished group of authors from ten countries, representing an array of disciplines. They include plant protection scientists and officers, economists, agronomists, ecologists, environmental and public health scientists and government policymakers. Over the course of eighteen chapters, those experts share their insights into and analyses of an array of issues of vital concern to everyone with a professional interest in this important subject. The adverse effects of pest control have become a subject of great concern worldwide, and researchers and enlightened policymakers have at last begun to appreciate the impact of environmental factors on our ability to manage pest populations. Moreover, while issues such as pesticide toxicity have dominated the global conversation about pest management, economic and societal considerations have been largely neglected. Environmental Pest Management: Challenges for Agronomists, Ecologists, Economists and Policymakers is the first work to provide in-depth coverage of all of these pressing issues between the covers of one book. Offers a unique multi-dimensional perspective on the complex issues surrounding pest management activities and their effect on the environment and human health Addresses growing concerns about specific pest management strategies, including the use of transgenic crops and biological controls Analyses the influence of global processes, such as climate change, biological invasions and shifts in consumer demand, and ecosystem services and disservices on pest suppression efforts Explores public health concerns regarding biodiversity, pesticide use and food safety Identifies key economic drivers of pest suppression research, strategies and technologies Proposes new regulatory approaches to create sustainable and viable crop protection systems in the framework of agro-environmental schemes Offering a timely and comprehensively-unique treatment of pest management and its environmental impacts in a single, inter-disciplinary volume, this book is a valuable resource for scientists in an array of disciplines, as well as government officials and policymakers. Also, teachers of undergraduate and graduate level courses in a variety of fields are sure to find it a highly useful teaching resource.

Since the arrival of Europeans about 500 years ago, an estimated 50,000 non-native species have been introduced to North America (including Hawaii). Non-native species figure prominently in our lives, often as ornamentals, sources of food or pests. Although many introduced species are beneficial, there is increasing awareness of the enormous economic costs associated with non-native pests. In contrast, the ecological impacts of non-native species have received much less public and scientific attention, despite the fact that invasion by exotic species ranks second to habitat destruction as a cause of species loss. In particular, there is little information about the ecological impacts of hyper-diverse groups such as terrestrial fungi and invertebrates. A science symposium, Ecological impacts of non-native invertebrates and fungi on terrestrial ecosystems, held in 2006, brought together scientists from the USA and Canada to review the state of knowledge in this field of work. Additional reviews were solicited following the symposium. The resulting set of review/synthesis papers and case studies represents a cross-section of work on ecological impacts of non-native terrestrial invertebrates and fungi. Although there is a strong focus on Canadian work, there is also significant presentation of work in the northern USA and Europe.

Publisher Description

The world is in the midst of an ecological explosion with devastating implications. Thousands of species of microbes, plants, and animals are being introduced, both deliberately and inadvertently, to new land areas, seas, and freshwaters. In many regions, these new colonists are running wild, disrupting the dynamics of ecosystems, pushing native species toward extinction, and causing billions of dollars in direct economic damages.Alien Species in North America and Hawaii provides a comprehensive overview of the invasive species phenomenon, examining the threats posed and the damage that has already been done to ecosystems across North America and Hawaii. George W. Cox considers both the biological theory underlying invasions and the potential and actual effects on ecosystems and human activities. His book offers a framework for understanding the problem and provides a detailed examination of species and regions. Specific chapters examine: North American invaders and their threats how exotic species are dispersed to new regions how physical and biotic features influence the establishment and spread of invasives patterns of exotic invasions, with separate chapters covering each of the ten most seriously invaded regions and ecosystems patterns of invasiveness exhibited by major groups of exotics the theory of invasive capability of alien species and the resistance of communities to invasion theoretical aspects of ecosystem impacts of invaders and the evolutionary interaction of invaders and natives management and public policy issuesAlien Species in North America and Hawaii offers for the first time an assessment and synthesis of the problem of invasive species in North American and Hawaiian ecosystems. Scientists, conservation professionals, policymakers, and anyone involved with the study and control of invasive species will find the book an essential guide and reference to one of the most serious and widespread threats to global biodiversity.
