The concept of Integrated Pest Management (IPM) was developed as an alternative to chemical pesticides following the widespread realization or their horrifying and damaging effects on environment, human, animal and plant health, which were vividly portrayed in Rachel Carsons book Silent Spring. The IPM approach involves the use of different tactics in compatible combinations to keep pest populations below the levels at which they cause economics injury. Thus. the IPM approach minimizes the use of chemical pesticides and avoids their harmful effects. The development and implementation of IPM has been increasing in North America with successful results. However, its role in tropical agriculture is less well known. For this reason, the United Nations Environment Programine (UNEP), and the International Center for Insect Physiology and Ecology (ICIPE) undertook a global review of IPM to assess the impact of related activities in tropical regions of Asia. Africa and South America. This volume assesses the current status and future prospects for IPM in these regions, it provide a unique overview of the efforts made to develop and implement IPM for the pests of livestock and agroforestry in selected countries in the tropics (including India and China), as well as a survey of IPM strategies on a crop-by-crop basis for each continent. The book gives an honest appraisal of both the successes and failures of past IPM programmes and provides new paradigms and directions that IPM must develop, if it is to be adopted by farmers and governments on a scale necessary to change their current reliance on chemical pestioldes

Evolution gave rise to a prominent insect diversity at every level of ecological niche. Since then, hordes of insects have threatened human and cattle health as well as most of all green lands and agricultural crops. Now, the insect problem expands from many mutant forms of yellow dengue fever mosquitoes to highly-resistant larvae of most all various phytophageous species. The tremendous expansion of insects is due not only to an increasing resistance capacity to insecticides, but also to a strong capacity for adapting to different climate and environmental changes, including global warming. Obviously insects display a number of rudimentary systems to build an extremely efficient organism to survive in a changing world. In many species, one pheromone molecule is enough to trigger mating behavior. Therefore, insects have become crucial models not only for evolutionary studies, but also for understanding specific mechanisms underlying sensory-based behaviors. Most of insect species such as ants, beetles, cockroaches, locusts, moths and mosquitoes largely rely on olfactory cues to explore the environment and find con-specifics or food sources. A conglomerate of renowned international scientific experts is gathered to expose the insect problem on the various continents of the planet and propose an alternative to the use of toxic insecticides. Sex pheromones, specific chemical signals necessary for reproduction, and pheromone detection in insects are described with full details of the olfactory mechanisms in the antennae and higher centers in the brain. Thus, new synthetic pheromones and/or plant odors with specific molecular target sites in the insect olfactory system are proposed for sustainable development in agricultural and entomological industries. Disrupting insect pheromone channels and plant odor detection mechanisms is solemnly envisioned as a unique way to control invasive insect pest species while preserving human and environment safety.

Commensal rodents pose health risks and cause substantial damage to property and food supplies. Rats have also invaded islands and pose a serious threat to native wildlife, particularly raptors and seabirds. Estimates of total damage from introduced rats range into the billions of dollars in developed countries. This book aims to provide a state-of-the-art overview of the scientific advancements in the assessment of exposure, effects and risks that currently used rodenticides may pose to non-target organisms in the environment, along with practical guidance for characterization of hazards. This will be discussed in relation to their efficacy, and the societal needs for rodent control, and discussion of risk mitigation and development of alternatives. The flow in the book is planned as: a. introduction and setting the scene b. problem description (risks and effects on non-targets and secondary poisoning, development of resistance) c. ; alternatives, regulation and risk mitigation d. conclusions and recommendations

It has been reported that up to 95% of all flowering plants require the services of other organisms to move pollen from male to female flower parts during the pollination process. These organisms, including bees, are collectively known as pollinators. However, in light of the growing evidence of global declines in pollinator species, the management, ecology and conservation of wild and managed pollinators is a subject of growing importance and research activity. Promoting pollination and pollinators in farming reviews the wealth of research on our current understanding of existing pollination processes and their importance to our global ecosystems. The book considers how pollinators interact with plants, as well as the major threats to pollinator species, including climate change, diseases and pesticide exposure. Through its comprehensive exploration of the current status of pollinators in farming, the book provides its readers with the knowledge required to promote pollination by protecting the world's pollinators species and the ecosystem services they deliver using techniques such as habitat conservation.

Plant galls may be produced by a wide variety of organisms, from fungi to parasitic insects, on an equally wide variety of hosts. Their taxonomy is highly complex, as are the life cycles of the organisms associated with them. Yet, common as they are, plant galls are often poorly understood. This book brings together information from the diverse disciplines involved in the study of plant galls: ecology, evolution, molecular biology, physiology, and developmental biology. The work considers the latest issues, covering questions of classification, coevolution, ecology, physiology, and plant genetic engineering. As an up-to-date resource in an area of immense interest and debate, the book will enhance the quality of discussion surrounding these phenomena, across all disciplinary perspectives.

This book examines social processes that have contributed to growing pesticide use, with a particular focus on the role governments play in urban aerial pesticide spraying operations. Beyond being applied to sparsely populated farmland, pesticides have been increasingly used in densely populated urban environments, and when faced with invasive species, governments have resorted to large-scale aerial pesticide spraying operations in urban areas. This book focuses on New Zealand's 2002-2004 pesticide campaign to eradicate the Painted Apple Moth, which is the largest operation of its kind in world history, whether we consider its duration (29 months), its scope (at its peak the spraying zone was 10,632 hectares/26,272 acres), the number of sprayings that were administered (the pesticide was administered on 60 different days), or the number of people exposed to the spraying (190,000+). This book provides an in-depth understanding of the social processes that contributed to the incursion, why the government sought to eradicate the moth through aerial pesticide spraying, the ideological strategies they used to build and maintain public support, and why those strategies were effective. Urban Aerial Pesticide Spraying Campaigns will be of great interest to students and researchers of pesticides, environmental sociology, environmental history, environmental studies, political ecology, geography, medical sociology, and science and technology studies.

A UN report presented to the UN Human Rights Council in 2017 recognized that, "although pesticide use has been correlated with a rise in food production, it has had catastrophic impacts" on human health and the environment. The report acknowledged that "increased food production has not succeeded in eliminating hunger worldwide because of the many interacting factors involved. Reliance on hazardous pesticides is a short-term solution that undermines the rights to adequate food and health for present and future generations." It is hoped that the knowledge available in Synthetic Pesticide Use in Africa: Impact on People, Animals, and the Environment will both enlighten the reader to present serious concerns on the use of synthetic pesticides, and motivate society to make the changes necessary for the sustainable production of safe, nutritious, and affordable food for the anticipated 250 billion inhabitants of this Earth in 2050. Key Features: * Explains the relationship of synthetic pesticides to escalating noncommunicable human and animal diseases in Africa and developing countries. * Discusses the impact of the herbicide glyphosate on the health of humans, animals, and the environment. * Reviews the disease causing mode of action of glyphosate and other synthetic pesticides on nutrient density and human and animal bodies. * Warns of the special vulnerability of children to synthetic pesticide toxicity. * Recommends needed legal initiatives to use synthetic pesticides more judiciously. The book is divided into seven (7) sections: I. General Impact, explains the general impact of synthetic pesticides on the African people, their animals, and environment. II. Human Health, covers the impact of synthetic pesticides on the human body, while III, Children's Health, focuses on the special vulnerability of children to synthetic pesticides. IV. Animal Health describes the synthetic pesticide threats to animal production and sustainability. V. Environmental Health presents the threat of synthetic pesticides to soil microbiota and sustainable remediations. VI. Control Strategies discusses biologically-based alternatives to synthetic pesticides. Finally, VII. Reglatory Control presents some legal initiatives to combat the misuse of synthetic pesticides.

Among the highlights of this book is the use of novel insecticides acting on a specific site in an insect group and are compatible with natural enemies and the environment. One of such approaches is based on disrupting the activity of biochemical sites acting on transcription factors such as the Helix-Loop-Helix (bHLH) family, anti juvenile hormone (AJH) agents that target JH biosynthetic enzymes, G-protein coupled receptors (GPCR) and bursicon as a target for insect control. Another one is the biotechnology or the genetic approach such as gene silencing (RNA interference) and Bt-crops. Other sections of the book are devoted to the plant s natural products, optical manipulation and the use of nanotechnology for improving insect control methods."

Featuring completely updated chapters, additional authors, and an increased emphasis on alternatives to traditional pesticides, the second edition of Ecological Entomology is the field's leading reference on the role of insects in ecosystems. The authors cover insect growth and development, what they eat, how they reproduce, and how they move in various environments. The book also examines how insects interact with the plant community and how to control insect populations naturally.

Aquatic weeds cause serious problems in water bodies throughout the world. They can, for example, block irrigation and drainage channels, interfere with fisheries, hinder navigation, and have environmentally undesirable effects on fresh-water ecosystems. The problems are most severe in tropical and subtropical countries, but they occur almost everywhere. The management of aquatic weeds poses special problems of its own. The main difficulty is to balance effective treatment against the undesirable side-effects that control operations may have on the ecosystem. This book, which is published for the European Weed Research Society, provides a detailed overview of the ecology and management of aquatic weeds, as well as the present status of aquatic weed problems in various continents. The environmental consequences of aquatic weed control measures are discussed in detail. The book will be of special interest to weed scientists, ecologists, agriculturalists, extension personnel, policy makers, and students.
