To date, more than a million insect species have been described, with probably at least another 5-8 million species waiting in the wings for a name. Insects are a fascinatingly diverse and beautiful spectrum of animals. They range in size from the tiny parasitic wasp, measuring a mere 139m, to the aptly named Titan beetle, which can reach lengths of up to 17cm. They can be found on all continents of the world, from the Sahara Desert to the frozen wastes of Antarctica; in caves, under the ground, inside plants, other insects and vertebrates, in rivers, streams, lakes and ponds, in puddles, in the watery interiors of pitcher plants; and in our houses. While no insects live beneath the waves, the intrepid sea skaters skim the surface of some of the world's oceans. This Very Short Introduction explores the extraordinary world of insects. It analyses insect evolution, taxonomy and development, and describes their behaviour, their life styles, and the interactions they have with other insects and other animals. As Simon Leather shows, insects are the bedrock on which human civilisation rests; without them we would almost certainly not exist. Although they can be seen as pests of our crops plants, they are also invaluable for pollinating our flowering plants and are an invaluable link in all land ecosystems. As they face challenges from climate change and pesticides it has never been more important to understand these oft-dismissed creatures. Very Short Introductions: Brilliant, Sharp, Inspiring ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
Green pesticides, also called ecological pesticides, are pesticides derived from organic sources which are considered environmentally friendly and are causing less harm to human and animal health and to habitats and the ecosystem. Essential oils based insecticides started have amazing features. This book gives a full spectrum of the whole range of essential oil based pesticides that may be used in pest control. It discusses the uses and limitations, including the recent advances in this area. It describes the metabolism and mode of action, and provides the present status of essential oil based pesticide residues in foodstuffs, soil and water.
Fruit fly (Diptera: Tephritidae) pests have a profound impact on horticultural production and economy of many countries. It is fundamental to understand their biology and evaluate methods for their suppression, containment, or eradication. Area-Wide Management of Fruit Fly Pests comprises contributions from scientists from around the world on several species of tephritids working on diverse subjects with a focus on area-wide management of these pests. The first three sections of the book explore aspects of the biology, ecology, physiology, behavior, taxonomy, and morphology of fruit flies. The next two sections provide evidence on the efficacy of attractants, risk assessment, quarantine, and post-harvest control methods. The fifth and sixth sections examine biological control methods such as the Sterile Insect Technique and the use of natural enemies of fruit flies. The seventh section focuses on area-wide integrated pest management and action programs. Finally, the eighth section examines social, economic, and policy issues of action programs aimed at involving the wider community in the control of these pests and facilitate the development of control programs. Features: Presents information on the biology of tephritid flies. Provides knowledge on the use of natural enemies of fruit flies for their biological control. Includes research results on models and diets used for the Sterile Insect Technique. Reports developments on the chemical ecology of fruit flies that contribute to make control methods more specific and efficient. Reviews subjects such as Holistic Pest Management and Area-Wide Management Programs including social, economic, and policy issues in various countries.

Chelicerates do not possess dedicated antennae like the Mandibulata but have evolved their second sets of appendages into the eponymous chelicerae. In scorpions, pectines are specialized comb-like structures, located on the ninth body segment, used for examining the substrate for chemo- and mechanosensory signals. The comb teeth, or pegs, are truncated beveled structures facing the substrate for probing, and are studded with numerous sensory receptors. Afferents from the pectines project into a distinct neuropil of the central nervous system, located behind the fourth walking leg neuropils. Denise Drozd analyzes afferents of single pegs in Mesobuthus eupeus by backfilling, combined with immunohistological labeling of neuropil regions. Her results suggest a topographic representation of the chemosensory fibers within the pectine neuropil instead of the typical chemotopic representation.

We think of bees as being among the busiest workers in the garden, admiring them for their productivity. But amid their buzzing, they are also great communicators and unusual dancers. As Karl von Frisch (1886-1982) discovered during World War II, bees communicate the location of food sources to each other through complex circle and waggle dances. For centuries, beekeepers had observed these curious movements in hives, and others had speculated about the possibility of a bee language used to manage the work of the hive. But it took von Frisch to determine that the bees' dances communicated precise information about the distance and direction of food sources. As Tania Munz shows in this exploration of von Frisch's life and research, this important discovery came amid the tense circumstances of the Third Reich.The Dancing Bees draws on previously unexplored archival sources in order to reveal von Frisch's full story, including how the Nazi government in 1940 determined that he was one-quarter Jewish, revoked his teaching privileges, and sought to prevent him from working altogether until circumstances intervened. In the 1940s, bee populations throughout Europe were facing the devastating effects of a plague (just as they are today), and because the bees were essential to the pollination of crops, von Frisch's research was deemed critical to maintaining the food supply of a nation at war. The bees, as von Frisch put it years later, saved his life. Munz not only explores von Frisch's complicated career in the Third Reich, she looks closely at the legacy of his work and the later debates about the significance of the bee language and the science of animal communication. This first in-depth biography of von Frisch paints a complex and nuanced portrait of a scientist at work under Nazi rule. The Dancing Bees will be welcomed by anyone seeking to better understand not only this chapter of the history of science but also the peculiar waggles of our garden visitors.

"[In] a revision of the 1963 edition, [a] brief, clearly written text [tells of a young girl who] learns some interesting facts about fireflies from her grandfather. Alexander uses richly hued pastels for her illustrations of the young girl, her grandparents' farm, and the creatures of a summer night."—SLJ.
Originally published in 1915, this book was written by the renowned British geneticist Reginald Crundall Punnett (1875-1967). Intended to appeal to a broad range of readers, the text presents a concise discussion of mimicry in butterflies and the role of mimicry in the evolutionary process. Illustrative figures and notes are included. This book will be of value to anyone with an interest in butterflies, the development of evolutionary theory and the history of science.
The history of biological control of harmful organisms by mites is marked by outstanding achievements with a few premiere natural enemies. Early works concentrated on the use of predatory mites for the control of synanthropic flies, More recently, the focus has been mostly on mites of the family Phytoseiidae for the control of plant feeding mites. This is an important family of acarine predators of plant pest mites, which are effectively used in agriculture worldwide. Besides the vast knowledge in several species in this family, there are as well many opportunities for biological control, represented in an array of organisms and through the improvement of management techniques, which are constantly explored by researchers worldwide. This has resulted in an increasing interest in predatory mite species within the families Stigmaeidae, Ascidae, Laelapidae, Rhodacaroidea, Macrochelidae, Erythraeidae and Cheyletidae, among others. This book will compile important developments with predatory mite species within these families, which are emerging as important tools for integrated pest management. New developments with predatory insects and pathogenic organisms attacking mites will also be a subject of this book. Finally, the potential and gaps in knowledge in biological control of acarine plant pests will be addressed.
This volume describes the various applications of entomopathogenic soil microorganisms in the management and control of the devastating lepidopteran pest. An introduction describes the insecticidal properties of viruses, bacteria, fungi, nematodes and their metabolites, as well as their applications in the context of crop improvement. Subsequent chapters focus on topics such as insecticidal proteins; the role of nucleopolyhedroviruses; Bt toxins and their receptors; control of lepidopterans using entomopathogenic fungi; management of cotton defoliators; and sustainable use of entomopathogenic nematodes and their bacterial symbionts. An overview of culture collections of entomopathogenic microorganisms rounds out the volume.
The first soil survey in the Philippines was done by Mr. Clarence Dorsey, an American soil scientist in the province of Batangas in 1903. The Soils of the Philippines, however, is the first comprehensive summary of more than a century of soil-survey work in this country. It integrates the soil concepts of the reconnaissance soil-survey results, which commenced as early as 1934 and continued until the mid 1960s, with the semi-detailed soil surveys that continue to this day. The result is the first-ever genetic key for classifying Philippine soils at soil series level; thus, making it possible for any newcomers to the soil survey field to confidently produce their own soil map, at a more detailed map scale, to suit the project requirements. This book brings together discussions on soils and soil mapping units and up-to-date international techniques and technologies. It makes soils relevant to current political realities and national issues. As soil survey moves from a reductionist agricultural-development planning tool to a more holistic and integrated approach, to enable us to understand our dynamic and complex environment, The Soils of the Philippines will be the only source of authoritative and updated data on soil resources for macro-level resource management planning for decades to come. With a vanishing breed of experienced soil surveyors, not only in the Philippines but also worldwide, it may remain the only book on Philippine soils for the next hundred years or more. Since soils follow a geological and not a human time frame, the contents of this volume will stay relevant for soil surveyors even in a fast changing world. As the country leaps from an agricultural economy towards modernization and a more diversified economic base, some of the soil series in the Philippines, for example the Guadalupe series underlying the skyscrapers of Makati City, are becoming extinct as a result of urban development. Therefore, this book serves as the repository for the soils that we possess, the soils that have been lost through decades of urbanization while, at the same time, it creates a soil classification system for the soils we are yet to discover.
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.
Three major aspects that distinguish this book are that (1) it contains the most detailed analysis of the sexual reproduction (oogenesis, fertilization and embryonic incubation) in a particular phylum of the aquatic invertebrates (Bryozoa) ever made; this analysis is based on an exhaustive review of the literature on that topic published over the last 260 years, as well as extensive original histological, anatomical and morphological data obtained during studies of both extant and extinct species; (2) this broad analysis has made it possible to reconstruct the major patterns, stages and trends in the evolution of sexual reproduction in various bryozoan clades, showing numerous examples of parallelisms during transitions from broadcasting to embryonic incubation, from planktotrophic to non-feeding larvae and from lecithotrophy to placentation; corresponding shifts in oogenesis, fertilization and embryonic development are discussed in detail; and (3) the key evolutionary novelties acquired by Bryozoa are compared with similar innovations that have evolved in other groups of marine invertebrates, showing the general trends in the evolution of their sexual reproduction. Ecological background of these innovations is considered too. Altogether these aspects make the monograph an “Encyclopedia of bryozoan sexual reproduction,†offering an integral picture of the evolution of this complex phenomenon.
More than two thirds of all living organisms described to date belong to the phylum Arthropoda. But their diversity, as measured in terms of species number, is also accompanied by an amazing disparity in terms of body form, developmental processes, and adaptations to every inhabitable place on Earth, from the deepest marine abysses to the earth surface and the air. The Arthropoda also include one of the most fashionable and extensively studied of all model organisms, the fruit-fly, whose name is not only linked forever to Mendelian and population genetics, but has more recently come back to centre stage as one of the most important and more extensively investigated models in developmental genetics. This approach has completely changed our appreciation of some of the most characteristic traits of arthropods as are the origin and evolution of segments, their regional and individual specialization, and the origin and evolution of the appendages. At approximately the same time as developmental genetics was eventually turning into the major agent in the birth of evolutionary developmental biology (evo-devo), molecular phylogenetics was challenging the traditional views on arthropod phylogeny, including the relationships among the four major groups: insects, crustaceans, myriapods, and chelicerates. In the meantime, palaeontology was revealing an amazing number of extinct forms that on the one side have contributed to a radical revisitation of arthropod phylogeny, but on the other have provided evidence of a previously unexpected disparity of arthropod and arthropod-like forms that often challenge a clear-cut delimitation of the phylum.
This entry in the series Pediatric Cancer offers comprehensive information on a variety of cancers, concentrating on brain tumors, the most common solid tumors and the leading cause of cancer-related mortality in children. The contents are organized in seven sections: Neuroblastoma, Medulloblastoma, Leukemia, Lymphoma, Rhabdoid, Sarcoma and Miscellaneous Tumors. Coverage includes pediatric medulloblastoma, and treatments including craniospinal radiation followed by adjuvant chemotherapy. The contributors explain diagnosis and chemotherapy of children with acute lymphoblastic leukemia, and diagnosis of bone marrow involvement in pediatric lymphoma patients. Ewing's sarcoma, a highly malignant connective tissue neoplasm formed by the proliferation of mesenchymal cells, receives extensive coverage, including targeting of molecular pathways and chemotherapy and surgical treatment. The roles of apoptotic genes, MYCN gene, MDM2, and SNP309, P13K inhibitors, alternative splicing and microRNAs, activated leukocyte cell adhesion molecule and inhibition by alu-like RNA in neuroblastoma are discussed in detail. The book explores the molecular genetics, diagnosis, prognosis and therapy of the atypical teratoid/rhabdoid tumor (AT/RT). Among the most common malignant neoplasms in children, AT/RT exhibits similarities with other CNS tumors, which can lead to misclassification, as pointed out in the book. The contributors discuss diagnosis of AT/RT type using imaging technology, and describe new strategies, including intensive multimodal therapy and high dose chemotherapy with autologous stem cell transplantation that have shown improved outcomes. Coverage of therapies includes total resection followed by aggressive chemotherapy and radiation. Discussion includes diagnosis and treatment of other pediatric tumors including adrenocortical tumors, supratentorial primitive neuroectodermal tumors, giant midline tumors, gastrointestinal stromal tumors, ependymomas and intramedullary cavernoma. Pediatric Cancer: Diagnosis, Therapy and Prognosis, Volume 4 includes contributions by ninety-one contributors - oncologists, neurosurgeons, physicians, research scientists and pathologists - representing thirteen countries. The editor, M.A. Hayat, is a Distinguished Professor in the Department of Biological Sciences at Kean University, Union, New Jersey, USA.
The book focuses on four broad topics related to trapping of agriculturally important tephritid fruit flies, namely i) lures and traps, ii) invasion biology and detection of infestations, iii) attract and kill systems, and iv) trade regulations and risk assessment. This comprehensive structure progresses from the biological interaction between insect and lures/traps to the area-wide use of trapping systems to the utilization and impact of trapping data on international trade. The chapters include accounts of earlier research but are not simply compendia and instead evaluate past and current work as a tool for critical analysis and proposal of productive avenues for future work. At present there is no book available that deals with fruit fly trapping in such a broad context. Our book fills this gap and serves as a global reference for both those interested in fruit flies specifically as well as anyone dealing with the threat of invasive agricultural insects in general.
A global synthesis of the impacts of wildfires and controlled burning on insects, bringing together much hitherto scattered information to provide a guide to improved conservation management practice. The great variety of responses by insect species and assemblages demonstrates the often subtle balance between fire being a severe threat and a vital management component. Examples from many parts of the world and from diverse biotopes and production systems display the increasingly detailed appreciation of fire impacts on insects in terrestrial and freshwater environments and the ways in which prescribed burning may be tailored to reduce harmful ecological impacts and incorporated into protocols for threatened species and wider insect conservation benefits.
Written in easy to follow language, the book presents cutting-edge agriculturally relevant plant biotechnologies and applications in a manner that is accessible to all. This book introduces the scope and method of plant biotechnologies and molecular breeding within the context of environmental analysis and assessment, a diminishing supply of productive arable land, scarce water resources and climate change. Authors who have studied how agro ecosystems have changed during the first decade and a half of commercial deployment review effects and stress needs that must be considered to make these tools sustainable.
This volume provides a comprehensive selection of recent studies addressing insect hearing and acoustic communication. The variety of signalling behaviours and hearing organs makes insects highly suitable animals for exploring and analysing signal generation and hearing in the context of neural processing, ecology, evolution and genetics. Across a variety of hearing species like moths, crickets, bush-crickets, grasshoppers, cicadas and flies, the leading researchers in the field cover recent scientific progress and address key points in current research, such as: - How can we approach the evolution of hearing in insects and what is the developmental and neural origin of the auditory organs? - How are hearing and sound production embedded in the natural lifestyle of the animals, allowing intraspecific communication but also predator avoidance and even predation? - What are the functional properties of hearing organs and how are they achieved at the molecular, biophysical and neural levels? - What are the neural mechanisms of central auditory processing and signal generation? The book is intended for students and researchers both inside and outside of the fascinating field of bioacoustics and aims to foster understanding of hearing and acoustic communication in insects.
This work, a sequel to Honeybees and Wax published nearly 30 years ago, starts with a brief introduction and discussion of nesting sites, their spaces and densities, self-organization of nest contents, and interspecific utilization of beeswax. The following chapters cover communication by vibrations and scents and wax secretion, and discuss the queen in relation to the combs. Discussions on completed nests include the significance of brood, the roles of pollen and nectar flow, and comb-building, and are followed by a triad of related chapters on the construction of cells and combs and their energetic costs. An in-depth examination of the conversion of wax scales into combs, the material properties of scale and comb waxes, and the wax gland complex are presented. The next chapters are devoted to a comprehensive analysis of the literature on the chemistry and synthesis of beeswax, and, finally, the material properties of honeybee silk are highlighted.
Originally published in 1920, this book was predominantly aimed at fruit growers and was one of the most comprehensive reference guides to pests and fungus diseases at this time. Part one of the book focuses on common insect pests such as the caterpillar, the winter moth and the beetle, discussing their features and environment, whilst part two of the book examines the myriad fungus diseases of fruit and hops and details the intrinsic traits of each disease. Part three goes on to discuss the diverse methods of spraying and deals with prevention, remedies and treatment. Additionally, the book contains multiple illustrations and historic photographs. This book is an important record of the most prevalent pests and fungus diseases in the early twentieth-century landscape and will be of particular value to anyone interested in the history of botany and agricultural science. |
