Climate Change And The Economic Importance And Damages Of Insects

Insects are considered the largest group of animals on earth, as they represent more than one million documented species and about half of all species on a global scale. This makes this group of animals essential for global functioning and survival. Climate change is disrupting the distribution and abundance of insects and will have serious repercussions for human well-being. Climate Change and the Economic Importance and Damages of Insects presents a set of scientific studies in the field of economic entomology in the context of climate change, which is a critical research area that affects human well-being. Covering key topics such as pollination, crops, and economic damages, this premier reference source is ideal for environmentalists, scientists, researchers, scholars, academicians, practitioners, instructors, and students.

Insects, being poikilothermic, are among the organisms that are most likely to respond to changes in climate, particularly increased temperatures. Range expansions into new areas, further north and to higher elevations, are already well documented, as are physiological and phenological responses. It is anticipated that the damage by insects will increase as a consequence of climate change, i.e. increasing temperatures primarily. However, the evidence in support of this common “belief” is sparse. Climate Change and Insect Pests sums up present knowledge regarding both agricultural and forest insect pests and climate change in order to identify future research directions.

An advanced textbook that reviews the conceptual approaches and the most important advances in our current understanding of insect physiology, ecology, evolution and conservation, in the ongoing and rapidly developing context of global anthropogenic climate change.

In the last few decades there has been an ever-increasing component in most BSc Zoology degree courses of cell biology, physiology and genetics, for spectacular developments have taken place in these fields. Some aspects of biotechnology are now also being included. In order to accommodate the new material, the old zoology courses were altered and the traditional two-year basis of systematics of the animal kingdom, comparative anatomy (and physiology) and evolution, was either severely trimmed or reduced and presented in an abridged form under another title. Soon after these course alterations came the swing to modular teaching in the form of a series of shorter, separate courses, some of which were optional. The entire BSc degree course took on a different appearance and several different basic themes became possible. One major result was that in the great majority of cases taxonomy and systematics were no longer taught and biology students graduated without this basic training. We field biologists did appreciate the rising interest in ecology and environ mental studies, but at the same time lamented the shortage of taxonomic skills, so that often field work was based on incorrect identifications. For years many of us with taxonomic inclinations have been bedevilled by the problem of teaching systematics to undergraduates. At a guess, maybe only 5% of students find systematics interesting. It is, however, the very basis of all studies in biology - the correct identification of the organism concerned and its relationships to others in the community.

This book focuses on understanding climatic effects on agricultural and forest pest populations. The importance of insect pests in providing an excellent framework for evaluating climatic effects on a wide range of ecological systems are also discussed.

This new innovative work on insects and their impact on the ecosystem covers the role of insects in environmental pollution, their use in sustainable agricultural services, and the industrial, forensic, and medical applications of insects and their pure products. The book also covers the entomological and molecular aspects of insects, identifies the gaps in the research, and looks at integrated management strategies for pests. Volume 1: Importance, Threats, Conservation, and Economic Perspectives, reviews the different insect orders regarding their diversity and importance in providing free ecological services and discusses the diversity patterns of world biogeographic zones and how insects contribute to maintaining ecological diversity. Volume 2: Environmental Indicators, Molecular Approaches, and Management Strategies discusses the role of insects as environmental indicators, the effect of pesticides on insect diversity, strategies to control the diversity of insects, medical and forensic importance of insects, exploring new insect species through DNA barcoding, integrated pest management, the role of insect population in agriculture, and eco-friendly pest management approaches. Some topics covered in the book include: Role of insects for the sustainable agricultural development Commercial importance of insects and their products Food additive roles of insects and formulation of remedies for the reduction of disease pathogenesis Management strategies for pest control Some specific topics include colony collapse disorder of managed honey bee (Apis mellifera l.) populations, insects as strong crime indicator tools in forensic sciences, insect-based value-added products, and more. Together, these two volumes offer important information for researchers, academicians, scientists, industrialists, teachers, entomologists, and students for understanding the contribution of insects towards the sustainability of the ecosystem.

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.

Insects and other biotic agents are a major source of forest disturbance in eastern North America, with the potential for widespread ecological, economic, and social consequences. Mitigating effects of pest outbreaks requires knowledge of the factors that regulate their populations, and for insects and other ectotherms, temperature is one of the most important of these factors. Here, we tested a number of hypotheses focusing on the effects of different temperature regimes on population level processes. For each chapter we used the southern pine beetle (Dendroctonus frontalis), one of the most destructive forest insect pests, as a model species. This insect has undergone important changes in population abundance at both the northern and southern extremes of their distribution. We first investigated the influence of cold temperatures, which have become increasingly important as populations expand northward. We specifically examined the influence of overwintering temperatures on the population life stage structure. We hypothesized that colder temperatures could lead to a convergence of the life stage structure, and this could subsequently produce a high level of synchrony in their flight phenology the following spring. Results from a series of experimental tests, as well as theoretical explorations using development rate models supported this hypothesis; however, field observations were mixed. The second set of hypotheses focused on the effects of high temperature exposure on southern pine beetle populations. As climate change alters global surface temperatures, the occurrence of heat waves are predicted to increase. We analyzed longterm (74 years) temperature records to characterize high temperatures events in the southern pine region. This information was paired with a series of experimental tests of high temperature tolerance in the southern pine beetle, to determine how extreme high temperatures may be impacting southern populations. We experimentally tested both acute and chronic high temperature exposure in northern and southern populations of the beetle. Results from the climate analysis showed no significant change in yearly maximum temperatures throughout the southern pine region, and model results indicated that the characteristics of both common and rare heat waves had not changed over the 74 year study period. Experimental tests of high temperature exposure in southern pine beetle larvae showed a greater than expected tolerance to thermal extremes, and these results were consistent in both northern and southern populations. Overall, we conclude that high temperatures do not explain recent changes in southern pine beetle populations in their historic southern habitat.
