Ants that commonly invade homes, damage structures, inflict painful bites, or sting humans or their pets are considered pest ants. This illustrated identification guide highlights forty species of ants that pose difficulties in urban settings. Included are well-known invasive troublemakers such as the red imported fire ant and Argentine ant, as well as native species. After an introductory chapter on the evolution, biology, and ecology of pest ants, the book follows a taxonomic arrangement by subfamily. Each subfamily chapter includes separate illustrated keys to both the genera and species of that group to enable entomologists and pest control professionals to identify pest ants correctly. The species accounts cover biology, distribution, and methods for excluding and/or removing ants from human structures and landscapes. The authors focus on the ants' biology and nesting behavior, life cycles, and feeding preferences; an intimate understanding of these factors enables the implementation of the least toxic control methods available. A chapter on control principles and techniques encompasses chemical strategies, habitat and structural modifications, biological control, and integrated pest management methods. Urban Ants of North America and Europe also contains valuable information on the diagnosis and treatment of human reactions to ant stings and bites. This comprehensive reference work on these economically significant ants includes the scientific, English, French, Spanish, and German names for each species and a summary of invasive ant species in the United States and Europe.

In The Great Gypsy Moth War, Robert J. Spear presents the untold story behind the importation and release of the gypsy moth in North America and the astonishing series of coincidences that brought the state of Massachusetts to a decade-long war against this tenacious insect. Spear traces the events leading up to the beginning of the war in 1890, notes the causes of its failure, and shows the terrible legacy it left as the precedent for all subsequent insect-eradication campaigns. During the Civil War, when the supply of cotton from southern fields was disrupted, the owners of northern textile mills looked elsewhere for raw fiber. One source was silk. Among those experimenting with silkworm production was a Frenchman named Etienne Leopold Trouvelot, who had settled outside of Boston. It was Trouvelot who imported the gypsy moths and inadvertently allowed them to escape. Soon the invasion was on and a counteroffensive was required. Spear reveals the turbulent undercurrents in the eradication campaign when the enthusiasm of the entomologists in charge turned into desperation on the discovery that their alien adversary was much tougher than they thought. Fighting a war they could not win and dared not lose, the leaders of the campaign resorted to political maneuvering, cheap tricks, and outright misrepresentation to maintain a facade of success, urging the Commonwealth to continue funding the war long after any chance of victory had faded. More than just reviewing the important events of this historic episode, Spear tells the story in an engaging way, often through the firsthand accounts of those who were directly involved. Much of what Spear has written is new, the recounting is lively, and the information he presents shows that almost all of the previous beliefs about the campaign to eradicate the gypsy moths are myths. In the process, he also traces the rise of modern economic entomology and the birth of the pesticide industry.

Weeds are plants growing in the wrong place. By using several techniques to control weeds you reduce the chance that weed species will adapt to the control techniques, which is likely if only one technique is used. For example, if a herbicide is used over a long period of time, a weed species can build up a resistance to the chemical. A long-term integrated weed management plan, that considers all available management control techniques or tools to control weeds, can be developed for a particular area. Any integrated weed management plan or strategy should focus on the most economical and effective control of the weeds and include ecological considerations. The long term approach to integrated weed management should reduce the extent of weeds and reduce the weed seed stock in the soil. It should consider how to achieve this goal without degrading the desirable qualities of the land, such as its native ecology or agricultural crops. Controlling weeds is particularly important in the first few months after plantation when the plants are small and there's little shade. In commercial plantations where plants are grown on bare soil, sowing a ground cover can reduce the use of herbicides. Weed management is most successful when it involves an integrated approach using a variety of methods. There is a need to develop equipment better adapted to more environmentally-friendly situations. This book deals with the appearance and management of plants with different traits occurring as weeds on arable land.

The major objective of this book is to highlight the significance of phytonematodes in horticulture. Detailed and latest information on major aspects of phytonematodes associated exclusively with horticultural crops, which is the need of the day, is lacking. Hence, the book has been written mainly with the objective of providing its readers, comprehensive information on the advanced aspects related to phytonematodes associated with horticultural crops. It also provides basic information on plant parasitic nematodes since it is required for a better understanding of advanced topics. Several popular topics, information on which is already available in plenty, have been avoided. Thus, book explicates both the essential fundamental and advanced aspects pertaining to nematodes associated with horticultural crops. The book is conveniently divided into 13 chapters, which cover latest information on the major fundamental and advanced aspects related to phytonematodes including the role of phytonematodes in horticultural industry, phylogenetic and evolutionary concepts in nematodes, major phytonematodes associated with horticultural crops and their diagnostic keys, symptoms caused by phytonematodes and disease diagnosis, nematode population threshold levels, crop loss assessment, nematode diseases of horticultural crops and their management, nematode disease complexes, genetics of nematode parasitism, important nematological techniques and nematodes of quarantine importance. An exclusive chapter on novel methods of nematode management has been included mainly to provide the information on the latest molecules and novel modes of managing nematodes attacking horticultural crops. Routine nematode management aspects, information on which is already available, have not been discussed; instead, this topic reflects the changing scenario of future nematode management. Hence, this book can serve as a friendly guide to meet the requirements of the students, teachers and researchers interested in these 'hidden enemies' of the grower, apart from the research and extension personnel working under Public organizations, officials of State departments of Horticulture, Forestry, field workers and all those concerned and working with plant parasitic nematodes. Appropriate diagrams, convincing tables and suitable graphs/illustrations have been furnished at right places. A complete bibliography has also been included.

"Insects are the most species-rich and important organisms on earth, and that's why there are many university courses dedicated to the topic of Insects and Society. But, surprisingly, this is the first textbook specifically created for those courses. The content in this textbook is not only ideal for introductory courses, but it also is great for K12 instructors, insatiably curious children, and indeed anyone fascinated by insects and their impact on people." - Robert K. D. Peterson, Ph.D., Professor of Entomology, Montana State University and Past President, Entomological Society of America "Society is undervaluing the role of insects as pivotal drivers of ecosystem functioning and services. Addressing this deficit is a major merit of this book." - Teja Tscharntke, Professor and Head of the Agroecology Research Group at the University of Goettingen, Germany Insects are all around us, outweighing humanity by 17 times. Many are nuisances; they compete with us for food and carry some of our most devastating diseases. Many common pests have been transported worldwide by humans. Yet, some recent reports suggest dramatic declines in some important groups, such as pollinators and detritivores. Should we care? Yes, we should. Without insect pollinators we'd lose 35% of our global food production; without detritivores, we would be buried in un-decayed refuse. Insects are also critical sources for nutritional, medical and industrial products. A world without insects would seem a very different and unpleasant place. So why do insects inspire such fear and loathing? This concise, full-color text challenges many entrenched perceptions about insect effects on our lives. Beginning with a summary of insect biology and ecology that affect their interactions with other organisms, it goes on to describe the various positive and negative ways in which insects and humans interact. The final chapters describe factors that affect insect abundance and approaches to managing insects that balance their impacts. The first textbook to cater directly to those studying Insect and Society or Insect Ecology modules, this book will also be fascinating reading for anyone interested in learning how insects affect human affairs and in applying more sustainable approaches to "managing" insects. This includes K-12 teachers, undergraduate students, amateur entomologists, conservation practitioners, environmentalists, as well as natural resource managers, land use planners and environmental policy makers.

This book reviews interagency research and development of classical (importation) biological control of Bemisia tabaci (biotype B) conducted in the USA from 1992- 2002. The successful discovery, evaluation, release, and establishment of at least five exotic B. tabaci natural enemies in rapid response to the devastating infestations in the USA represents a landmark in interagency cooperation and coordination of multiple disciplines. The review covers all key aspects of the classical biocontrol program, beginning with foreign exploration and quarantine culture, through dev- opment of mass rearing methodology, laboratory and field evaluation for efficacy, to field releases, integration with other management approaches, and monitoring for establishment and potential non-target impacts. The importance of morphological and molecular taxonomy to the success of the program is also emphasized. The book's contributors include 28 USDA, state department of agriculture, and univ- sity scientists who participated in various aspects of the project. Bemisia tabaci continues to be a pest of major concern in many parts of the world, especially since the recent spread of the Q biotype, so the publication of a review of the biological control program for the B biotype is especially timely. We anticipate that our review of the natural enemies that were evaluated and which have established in the USA will benefit researchers and IPM practitioners in other nations affected by B. tabaci.

Weeds, insects, rodents, and pathogens are major problems in agricultural and urban environments; there is a clear need to augment chemical methods of control with biological methods. Until now these efforts have had limited success because of insufficient virulence of the host-specific organisms used. Naturally occurring biological agents are in evolutionary balance with their hosts, and attaining the level of control typically desired would lead to extinction of both the control agent and its host.In this book, the main researchers involved in enhancing fungal, bacterial, virus and insect biological control agents on different targets review progress in overcoming the barrier of insufficient virulence. This multi-disciplinary group, with backgrounds in many facets of biotechnology and crop protection, reviews their work and that of others, and describes the approaches, the successes and the remaining barriers in an integrated manner.
