Insect-scale flapping wing flight vehicles can conduct environmental monitoring, disaster assessment, mapping, positioning and security in complex and challenging surroundings. To develop bio-inspired flight vehicles, systematic probing based on the particular category of flight vehicles is needed. This Element addresses the aerodynamics, aeroelasticity, geometry, stability and dynamics of flexible flapping wings in the insect flight regime. The authors highlight distinct features and issues, contrast aerodynamic stability between rigid and flexible wings, present the implications of the wing-aspect ratio, and use canonical models and dragonflies to elucidate scientific insight as well as technical capabilities of bio-inspired design.
Thrips have recently surged to prominence as insect pests of field, plantation and glasshouse crops in many countries, associated with increased international trade in fresh vegetables, fruit, flowers and plant propagation material. They can cause direct feeding damage to the aerial parts of plants, resulting in yield loss and spoilage, and some are vectors of destructive plant viruses. Their minute size and secretive habits make them particularly difficult to detect and control. This book, containing contributions from several world authorities from Europe, the USA and Asia, is the most comprehensive treatise on thrips as crop pests ever to be published. It brings together a vast amount of modern work set against a wealth of background knowledge, covering basic biology, ecology, applied science and pest control. The result is a book indispensable for agricultural advisers and growers concerned with thrips pests, and a unique reference source and stimulus for research entomologists studying these intriguing insects.
This book addresses these topical issues and is based on a Discussion Meeting held at the Royal Society, London, in April 1998. Contributors include scientists from leading research groups in Europe, North America, Asia and Australia. The papers have also been published as an issue of the journal Philosophical Transactions: Biological Sciences, published by the Royal Society. Topics covered include molecular genetics, mechanisms, ecological genetics and management. There is also discussion of the genetically delivered toxicant derived from the insect pathogen Bacillus thuringiensis. The book is essential reading for agricultural, medical and veterinary entomologists concerned with pest management.
Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich's Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students.
This volume is a republication in one volume of the 10-part "CIH Keys to the Nematode Parasites of Vertebrates," first published between 1974 and 1983. For many years the "Keys" have provided a working tool to those within the field and laboratory needing to know "what is this worm?"Now due to popular demand and to coincide with the long awaited publication of the supplement volume, the "Keys" will be presented as one volume, refreshed and reformatted with the additional convenience of reordering into superfamily. As an indispensable guide the "Keys" shall continue to be an essential resource to those working within medical, veterinary and biological departments worldwide for many more years to come.
By providing multiple economic goods and ecosystem services, Latin American forests play a key role in the environmental, social and economic welfare of the region's countries. From the tropical forests of Central America to the Mediterranean and temperate vegetation of the southern cone, these forests face a myriad of phytosanitary problems that negatively impact on both conservation efforts and forest industry. This book brings together the perspectives of several Latin American researchers on pest and disease management. Each chapter provides modern views of the status and management alternatives to problems as serious as the impact of introduced exotic insects and diseases on Pinus and Eucalyptus plantations throughout the continent, and the emergence of novel insect outbreaks in tropical and temperate native forests associated with global warming. It is a valuable guide for researchers and practitioners working on forest health in Latin America and around the world.
This book reviews the latest research on bioproducts from various economically important insects, such as silkworms, honey bees, lac and drosophila, and termites, and discusses their general, biomedical and industrial applications in detail. It includes chapters focusing on insects as a food source, probiotics, silk-based biomaterials, insect pheromones, insects as biomedicine source, pupa oil chemistry, non-protein compounds from Lepidopteran insects, insect chitin and chitosan, polyphenols and flavonoids. Model insects like Bombyx mori or bees were domesticated in Asian countries thousands of years ago. Over time, natural products from these animals became industrialized and today they attracting increasing attention thanks to their sustainability and their manifold applications in agriculture and biomedicine. The book is intended for entomologists, material scientists, natural product researchers and biotechnologists.
This book provides an overview of our current understanding of polyembryony in insects. The study of polyembronic insects has advanced considerably over the last several decades.The book shows the exciting potential of polyembryonic insects and their impact on life sciences. It describes the mechanisms of polyembryogenesis; tissue-compatible invasion of the host, which is the first case of compatible cellular interaction between phylogenetically distant organisms without rejection; the sex differences in defense; and the environmental regulation of caste structure. The first book devoted to polyembryony in insects, it draws on the author's research on polyembryonic wasps from 1990 to the present day, covering various topics such as polyembryogenesis in vitro, host-parasite interaction, sex differences in soldier function/humoral toxic factor, and the transcription analysis of polyembryogenesis.It is intended not only for researchers in the field of entomology, parasitology, ontogeny, reproductive biology, developmental biology, sociobiology, and evolutionary developmental biology (Evo-Devo), but also for postgraduate students in these fields.
As the world's population and the demand for seafood increase, the
production of seafood from aquaculture has also seen massive
increase and is set to continue. With wild stocks of many molluscan
species depleted, aquaculture is firmly recognised as the means
now, and for the future, of bridging the gap between the supply and
demand of seafood.
This important book covers the general biology of bivalves,
hatchery culture methods and specific and comprehensive details of
the cultivation of many commercially important species, including
clams, oysters, mussels, scallops and abalone.
Based on the author's extensive experience and hands on research
into this subject, Molluscan Shellfish Farming provides essential
information for all involved in the culture of molluscs. The book
will be particularly useful for aquaculture personnel on working
fish farms and in academic research posts. Libraries in all
universities and research establishments where aquaculture and
biological sciences are studied and taught should have copies of
this book available.
Part of this book is based on a Buckland Lecture, sponsored by the Buckland Trustees
Insect and other pests cause major economic damage on fruit crops in the tropics. However, some insects are beneficial and have a role in pollinating flowers and thus enabling fruit set. This book, written by authors from around the world, reviews these injurious and beneficial organisms and how they might be controlled to enhance fruit production and quality.
The harvesting, processing and consumption of edible insects is one of the main keys to the sustainability of food chains on the African continent. Insects are the largest and most successful group of animals on the planet and it is estimated that they comprise 80% of all animals. This makes edible insects extremely important to the future survival of large populations across Africa and the world. Insects offer a complete animal protein that includes all 9 essential amino acids and are very competitive with other protein sources. They are also a good source of beneficial unsaturated fats, and many insects have a perfect Omega 3:6 balance. African Edible Insects As Alternative Source of Food, Oil, Protein and Bioactive Components comprehensively outlines the importance of edible insects as food and animal feed and the processing of insects in Africa. The text also highlights indigenous knowledge of edible insects and shows the composition and nutritional value of these insects, plus presents reviews of current research and developments in this rapidly expanding field. All of the main types of edible insects are covered, including their nutritional value, chemical makeup, and harvesting and processing details. The various preparation technologies are covered for each insect, as are their individual sensory qualities and safety aspects. A key aspect of this work is its focus on the role of insects in edible oils and gelatins. Individual chapters focus on entomophagy in Africa and the various key aspects of the continent's growing edible insect consumption market. As it becomes increasingly clear that the consumption of insects will play a major role in the sustainability of food chains in Africa, this work can be used as a comprehensive and up-to-date singular source for researchers looking for a complete overview on this crucial topic.
Australia's varied grasslands have suffered massive losses and changes since European settlement, and those changes continue under increasingly intensive human pressures for development and agricultural production. The values of native grasslands for conservation of endemic native biodiversity, both flora and fauna, have led to strong interests in the protection of remaining fragments, especially near urban centres, and documentation of the insects and other inhabitants of grasslands spanning tropical to cool temperate parts of the country. Attention to conservation of grassland insects in Australia is relatively recent, but it is increasingly apparent that grasslands harbour many localised and ecologically specialised endemic species. Their conservation necessarily advances from very incomplete documentation, and draws heavily on lessons from the far better-documented grasslands elsewhere, most notably in the northern hemisphere, and undertaken over far longer periods. From those cases, and the extensive background to grassland management to harmonise conservation with production and amenity values through honing use of processes such as grazing, mowing and fire, the needs and priorities for Australia can become clearer, together with needs for grassland restoration at a variety of scales. This book is a broad overview of conservation needs of grassland insects in Australia, drawing on the background provided elsewhere in the world on the responses to disturbances, and the ecological importance, of some key insect groups (notably Orthoptera, Hemiptera and Lepidoptera) to suggest how insect conservation in native, pastoral and urban grasslands may be advanced. The substantial references given for each chapter facilitate entry for non-entomologist grassland managers and stewards to appreciate the diversity and importance of Australia's grassland insects, their vulnerabilities to changes, and the possibilities for conserving them and the wider ecological roles in which they participate.
Teeming with weird and wonderful life--giant clams and mussels, tubeworms, "eyeless" shrimp, and bacteria that survive on sulfur--deep-sea hot-water springs are found along rifts where sea-floor spreading occurs. The theory of plate tectonics predicted the existence of these hydrothermal vents, but they were discovered only in 1977. Since then the sites have attracted teams of scientists seeking to understand how life can thrive in what would seem to be intolerable or extreme conditions of temperature and fluid chemistry. Some suspect that these vents even hold the key to understanding the very origins of life. Here a leading expert provides the first authoritative and comprehensive account of this research in a book intended for students, professionals, and general readers. Cindy Lee Van Dover, an ecologist, brings nearly two decades of experience and a lively writing style to the text, which is further enhanced by two hundred illustrations, including photographs of vent communities taken in situ. The book begins by explaining what is known about hydrothermal systems in terms of their deep-sea environment and their geological and chemical makeup. The coverage of microbial ecology includes a chapter on symbiosis. Symbiotic relationships are further developed in a section on physiological ecology, which includes discussions of adaptations to sulfide, thermal tolerances, and sensory adaptations. Separate chapters are devoted to trophic relationships and reproductive ecology. A chapter on community dynamics reveals what has been learned about the ways in which vent communities become established and why they persist, while a chapter on evolution and biogeography examines patterns of species diversity and evolutionary relationships within chemosynthetic ecosystems. Cognate communities such as seeps and whale skeletons come under scrutiny for their ability to support microbial and invertebrate communities that are ecologically and evolutionarily related to hydrothermal faunas. The book concludes by exploring the possibility that life originated at hydrothermal vents, a hypothesis that has had tremendous impact on our ideas about the potential for life on other planets or planetary bodies in our solar system.
This book explores one of the most discussed and investigated novel foods in recent years: edible insects. The increasing demand for alternative protein sources worldwide had led the Food and Agriculture Organization of the United Nations (FAO) to promote the potential of using insects both for feed and food, establishing a program called "Edible Insects." Although several social, environmental, and nutritional benefits of the use of insects in the human diet have been identified, the majority of the population in Western countries rejects the idea of adopting insects as food, predominantly for cultural reasons. Nevertheless, international interest in promoting the consumption of insects has grown significantly, mainly in North America and Europe. This trend is mostly due to increasing attention and involvement from the scientific network and the food and feed industries, as well as governments and their constituents. The book explores the current state of entomophagy and identifies knowledge gaps to inform primary research institutions, students, members of the private sector, and policymakers to better plan, develop, and implement future research studies on edible insects as a sustainable source of food. The case studies and issues presented in this book cover highly up-to-date topics such as aspects of safety and allergies for human consumption, final meat quality of animals fed with insects, the legislative framework for the commercialization of this novel food, and other relevant issues.
This book provides a comprehensive overview of chitin biology and chitin metabolism related enzymes. Chitin, the second most abundant biopolymer in nature after to cellulose, is a linear biopolymer composed of -1,4-linked N-acetylglucosamine (GlcNAc), and an essential component in the exoskeletons of insects, mites, ticks and crustaceans, the egg shells of parasitic nematodes, and fungal cell walls. Although some chitin-containing organisms are a threat to human health, food safety and agricultural production, non-chitin containing organisms like humans, mammals and plants have an innate immune response to these hazardous organisms. The book provides researchers and students with information on the recent research advances concerning the biology of chitin-containing organisms as well as cross-talks between chitin-containing and non-chitin-containing organisms. Highlighting chitin remodeling enzymes and inhibitors, it also offers drug developers essential insights into designing specific molecules for the control of hazardous chitin-containing organisms.
There are over 40 000 named species of mite, and if estimates for unnamed species are included, then up to 1 million may grace the planet. By comparison, there are approximately 40 000 species of vertebrates, half of them fish, alive today. Mites are predators, parasites, herbivores and detritivores. They live in the dark depths of the ocean, in the lungs of birds, on the leaves of rainforest plants, and in human clothes and bedding. They are vectors of disease, vital players in soil formation, and important agents of biological control. Despite the grand diversity of mites, these small arthropods are often overlooked, and even trained biologists can be unaware of their significance. This books aims to fill the gap in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites, without requiring prior knowledge of their morphology or taxonomy. The text is richly illustrated with line drawings and photographs. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, and mites as models of ecological and evolutionary theories.
This book is devoted to the welfare of invertebrates, which make up 99% of animal species on earth. Addressing animal welfare, we do not often think of invertebrates; in fact we seldom consider them to be deserving of welfare evaluation. And yet we should. Welfare is a broad concern for any animal that we house, control or utilize - and we utilize invertebrates a lot. The Authors start with an emphasis on the values of non-vertebrate animals and discuss the need for a book on the present topic. The following chapters focus on specific taxa, tackling questions that are most appropriate to each one. What is pain in crustaceans, and how might we prevent it? How do we ensure that octopuses are not bored? What do bees need to thrive, pollinate our plants and give us honey? Since invertebrates have distinct personalities and some social animals have group personalities, how do we consider this? And, as in the European Union's application of welfare consideration to cephalopods, how do the practical regulatory issues play out? We have previously relegated invertebrates to the category 'things' and did not worry about their treatment. New research suggest that some invertebrates such as cephalopods and crustaceans can have pain and suffering, might also have consciousness and awareness. Also, good welfare is going to mean different things to spiders, bees, corals, etc. This book is taking animal welfare in a very different direction. Academics and students of animal welfare science, those who keep invertebrates for scientific research or in service to the goals of humans, as well as philosophers will find this work thought-provoking, instructive and informative.
Describes the various stages of a monarch butterfly's life, from egg to pupa to caterpillar to butterfly, as well as its migration and dangers that it faces.
Mosquitoes are undeniably one of the most studied groups of insects due to their great impact on human health as the agents that transmit the pathogens which cause malaria, filariasis and numerous viral diseases, such as yellow fever and dengue fever. The study of mosquitoes has given rise to a plethora of names for subspecies, species, subgenera, genera and family-level groups, many of which are duplicate names for the same entity. This unique volume is a comprehensive compilation of all scientific names introduced at all levels of classification within the family since the official start of zoological nomenclature. The work is largely a lexicon that is historical and informative as well as nomenclatural and bibliographic. Unlike catalogues, it contains sections devoted separately to the groups of names regulated by the International Code of Zoological Nomenclature, the species, genus and family groups, as well as sections concerned with names derived from personal and geographical names and other sources. In addition to insights into the history of mosquito classification, attention given to the formation, latinization and derivation of names makes the work a crucial contribution to mosquito science. Culicipedia is an important comprehensive reference source for students, entomologists, professional taxonomists and other scientists interested in culicid nomenclature, classification and the etymology of scientific names.
Entomology as a branch of biological science has undergone rapid expansion and development in recent decades. There have been major advances in the technologies associated with pest management and the ecological studies that underpin much of this work. Greater emphasis is now placed on topics such as modelling and biochemical techniques, with new approaches to the study of insect behavior and insecticide efficacy making inroads into traditional approaches. This book aims to integrate the new approaches and technologies with traditional and well-proven methods. It provides a critical analysis and evaluation of methods available, through reference to general principles, but emphasis is also placed on providing detailed descriptions of methods and their application. Written by leading authorities from the UK, USA and Australia, the book is aimed at advanced undergraduate and postgraduate students in entomology and pest management.
Terrestrial hermit crabs are among the most widespread beach-dwelling organisms with key ecological functions but receive only very limited research attention. Sebastian Steibl demonstrates how physical parameters shape their overall distribution, presents a possible mechanism for their speciation and coexistence and shows for the first time how different human activities can have a major impact on their populations. The author points out that terrestrial hermit crabs, due to their conspicuous behavior to utilize shells, are a good model to study mechanisms of competition and coexistence in natural populations. Furthermore, they are suitable indicator organisms to assess human impact, as they respond differently depending on the type of anthropogenic disturbance. About the Author: Sebastian Steibl is a PhD student at the Institute of Animal Ecology at the University of Bayreuth, Germany. In his actual PhD research, he builds up on the presented work to investigate the architecture as well as functionality of small insular ecosystems and to analyze how different anthropogenic disturbances impact those ecosystem processes.
Written by a globally prominent entomologist, Agricultural Acarology: Introduction to Integrated Mite Management provides tools for developing integrated mite management programs for agriculture, including management of plant-feeding mites, mites attacking bees and livestock, and stored products. Emphasizing the biology, ecology, behavior, and diverse methods of controlling mites, this book provides an overview of the management of agriculturally important mites using all available Integrated Pest Management (IPM) tools, including biological control, cultural practices, host-plant resistance, and pesticides. Agricultural Acarology prepares agricultural managers to identify, manage, and contribute to the field of integrated mite management. An accompanying downloadable resource contains numerous color photographs of mites and the damage they cause, and PDFs of key publications.
The Acari, comprising mites and ticks, form one of the largest and
biologically most diverse groups of the Arachnida. They are
worldwide in distribution and rival the insects in the extent to
which they have successfully colonized terrestrial and aquatic
habitats. Some are significant crop pests, while ticks are
parasites on a wide range of vertebrate hosts. This diversity of
modes of life is reflected in their morphology and life-history
strategies. |
