This book suggests an in-depth look at nomenclature in systematics instead of providing another "instruction for use" of various Codes of nomenclature. The focus is on ideas of what taxonomic nomenclature is as a part of the professional language of systematics considered in its full historical and conceptual scope. Basic concepts of nomenclature are outlined, and their development characterized; a hierarchy of fundamental principles of nomenclature are summarized; and the relationship between taxonomic nomenclature and taxonomic theory discussed. This book is addressed to those who would like to go beyond the boundaries of existing Codes to look at the subject from a more general, mostly theoretical standpoint. Key Features * Provides a review of the role of nomenclature in systematics * Reviews the conceptual scope and historical contexts of nomenclature * Analyzes fundamental principles of nomenclature * Outlines the historical development of nomenclature * Reviews the rules of nomenclature in botany, zoology, microbiology, and horticulture Related Titles Mishler, B.

Although the ancestral home of chelicerates was the sea, the vast majority of modern species live on land. Most students of spiders and mites also restrict themselves to terrestrial habitats. However, a surprising number of mites (Arachnida: Acari) have returned to a watery existence. Approximately 7000 species from the Mesostigmata, Astigmata, Oribatida, and especially the Prostigmata, now live in marine and freshwater habitats. In Aquatic Mites, a dozen chapters explore the distribution, ecology, behavior, genetics, and evolution of the most diverse of these astonishing arachnids. The results of these studies raise as many interesting questions as they answer, and should provoke more investigations of the biology of freshwater and marine Acari.

Urban pests are common all over the world. These include cockroaches, flies, mosquitoes, bed bugs, ticks, fleas, ants, termites, rodents and others. These pests thrive in human structures, where there is food, warmth and places to hide. Urban pests are one of the leading causes of illnesses in humans due to allergies, bites, food contamination and phobias. They can also cause significant damage to property and structures. Knowledge and training in this field is vital for professional and trainee pest managers. This book is specifically intended to provide an aid to such candidates. The book contains 500 multiple-choice questions (and answers) grouped into the following major topic areas: * The history of urban entomology * Household pests * Cockroaches * Flies * Mosquitoes * Bed bugs * Termites * Sporadic pests * Stored product pests * Vertebrate pests * Pesticides and pesticide formulations * Handling pesticides * Integrated Pest Control Produced in a convenient format that can be used at any time in any place, the book allows the reader to learn and revise the subject and much more. Its structure allows the study of one topic area at a time, progressing through a simple introduction followed by key revision questions, many of which require students to use their practical knowledge. The answers to each of the questions are provided at the end with short explanations wherever appropriate.

Despite their enormous bulk and complexity of architecture, plants make up only around a quarter of a million of the 8 million or so species on Earth. The major components of biodiversity, instead, are the smaller, largely unseen, silent majority of invertebrates - most of which are arthropods. Vertebrates, a mere blip on the biotic horizon, are elevated in importance in the bigger scheme of things only by the human psyche.This collection of more than 30 peer-reviewed papers focuses on the diversity and conservation of arthropods, whose species inhabit virtually every recess and plane - and feature somewhere in virtually every food web - on the planet. Highlighting issues ranging from large-scale disturbance to local management, and from spatial heterogeneity to temporal patterns, these papers reflect some of the most exciting new research taking place today - and in some of the most biodiverse corners of the planet.

First published in 1993, completely rewritten, this second edition includes a list of all 210 countries of the world and all of the islands, with comments on the existence of insect and spider collections, both public and private. These listings are arranged alphabetically by country, state/province, and city, with private collections listed under the public collection with which they are registered. Part II of the directory is an alphabetical list of the codes assigned to each of the collections described in Part I. This list is also cross-referenced to variations of the codes used in other works, which will eliminate any confusion over this duplication. This classic work provides a ready reference to all collections and is required by all insect and spider systematists.

This book is a comprehensive elucidation on aspects of reproduction and development in platyhelminthes covering from acoelids to taeniids. With the unique presence of neoblasts, turbellarians serve as a model for studies on cancer and senescence. Of ~ 27,000 species, ~ 77% are parasites; they are harmful to man and his food basket from livestock and fish. The stress hormone, cortisol level is responsible for susceptibility and resistance of the host. In digeneans, the propagatory multiplication potency is retained by all the larval forms and in either direction in sporocyst. The higher clonal diversity, mixing and selection in Second Intermediate Host (SIH) may purge inbreeding depression suffered by the fluke on propagatory multiplication in First Intermediate Host (FIH). Of 12,012 digeneans, 88% may engage 33,014 potential SIH species. They have the choice to select one among the available/awaiting 3.5 host species. The motility of vertebrate host and euryxenic flexibility/scope for selection of SIH species has increased lineage diversification in digeneans. The life cycle of cestodes is divided into aquatic and terrestrial patterns. The former includes (i) oncosphere and (ii) coracidium types and the latter (iii) hexacanth-cysticercoid, (iv) hexacanth-tetrathyridium and (v) hexacanth-cysticercus types. The share for the oncosphere, coracidium and hexacanth types is 17.0, 29.5 and 46.5%, respectively. The staggering fecundity and adoption of the intermediate host in the herbivorous/insectivorous food chain have enriched Taenioidea as the most (2,264) speciose order. Sex specific genes Smed-dmd 1 and macbol have been identified, and neuropeptides and dipeptides are involved in sexualization. Trematodes are unable to parasitize elasmobranchs, as they cannot suck body fluid/blood containing a high level of urea. Relatively higher fecundity supplemented with propagatory multiplication, incorporation of SIH in 88% species, clonal selection in SIH, and euryxenic flexibility and the widest choice for selection of SIH have led to the highest lineage diversification to render digeneans as the most speciose order in Platyhelminthes.

There are many books on biological control, but this will bring up to date the regulatory and other specific challenges facing biological control, and how they are being met. It is the first book to bring together a comprehensive account of global activities in biological control, region-by-region, amalgamating information from introduction biological control, conservation biological control and augmentative biological control (including commercial use). Offers a historical summary of organisms and main strategies used in biological control. Outlines key challenges confronting biological control in the 21st century and describes the main socioeconomic challenges that need to be addressed. Global overview: summarises biological control efforts around the globe and highlights important successes and failures, providing suggestions to best move biological control forward in a changing world. Biological control is a fairly specialized field but one that is spread across a broad array of socio-environments in agriculture and public health around the world. There is also a significant regulatory component to a subset of this field (classical biological control) that researchers must navigate to achieve the aims of their research and its application. This book will help!

Bees are flying insects of the order Hymenoptera closely related to wasps and ants. The ancestors of bees are assumed to be predatory wasps, which switched to pollen consumption. Further, bees co-evolved with flowering plants and divided into several species according to climatic conditions. Widely known bees are western bees Apis mellifera, and eastern bees Apis cerana. This book sheds light on features of evolution, phylogenesis, speciation, adaptation to environment, and taxonomy of bees. It will be of particular relevance to evolutionists, geneticists, taxonomists, ecologists, population geneticist, and breeders.

Honeybees are an important link in our food chain because they are major pollinators of food crops. In recent years, honeybee populations have declined precipitously perhaps due to changes in their microbiome. This book describes and identifies the bee microbiome using a proteomics technology. Chapters include the detection and identification of microbes found in honeybees collected around the United States. This book contains new data and illustrates the rich diversity of microbes as collected by honeybees. It is a must read for everyone concerned about the honeybee and working in the industry.

A richly illustrated introduction to the incredible world of beetles With some 400,000 species, beetles are among the largest and most successful groups of organisms on earth, making up one-fifth of all plant and animal species. No other animals exhibit such a dazzling range of size, form, and color. Mostly small, sturdy, and compact, beetles are incredibly well-equipped to find food, reproduce, and avoid predators. Additionally, their collective roles as herbivores, hunters, and recyclers are critical to the sustainability of terrestrial ecosystems. In this lavishly illustrated book, beetle expert and author Arthur Evans presents an inviting and comprehensive introduction to the fascinating lives of the world's beetles. Universal in scope, The Lives of Beetles is packed with the latest scientific findings, presented in an accessible way. Individual chapters cover beetles' structure and function; evolution, diversity, classification, and distribution; communication, reproduction, and development; feeding habits; uses in medicine, science, and technology; and study and conservation. Each chapter concludes with nine stunningly illustrated profiles that highlight the lives of some of the world's most beautiful and interesting species. The book also features an up-to-date family classification, a glossary, and suggestions for further reading. We need beetles for the ecological services they provide, the technological innovations they inspire, and the scientific insights they reveal, so it is essential that we all get to know beetles better and strive to conserve their habitats. The Lives of Beetles is the perfect place to begin this journey of discovery and understanding.

The book introduces basic entomology, emphasising perspectives on insect diversity important in conservation assessment and setting priorities for management, as a foundation for managers and others without entomological training or background. It bridges the gap between photographic essays on insect identification and more technical texts, to illustrate and discuss many aspects of taxonomic, ecological and evolutionary diversity in the Australian insect fauna, and its impacts in human life, through outlines of many aspects of insect natural history.

Members of the phylum Echinodermata are among the most familiar marine invertebrates. Forms such as the sea star have become virtually a symbol of sea life. Used in ancient oriental medicine as a source of bioactive compounds, sea cucumbers, sea stars and sea urchins are now used for the extraction and purification of cytotoxic, haemolytic, antiviral, antifungal, antifouling, antimicrobial and even anti-tumoural activities. In addition, of the five extant classes, sea urchins and sea cucumbers are important economic resources for current fishery and aquaculture. Molecular and cell biological techniques described in this book are, on the one hand, indicative of the improvements made over the years and, on the other, stress the need of their further exploitation for the sustainable production of bioactive compounds and their application in biomedicine.

Reflects on insect pests' evolution by evaluating existing theories, documenting case studies of diverse pest species and presenting new concepts regarding the problem of variation and implications for pest management strategies. Leading experts offer contributions which deal with variations in genetic markers and ecologically meaningful traits as well as future perspectives in entomology and biosystematics.

This book is a concise informative elucidation of all aspects of reproduction and development in annelids covering from arenicola to tubifex. Annelids flourish between 4,900 m depth to 2,000 m altitude; some of them occur in unusual habitats like hydrothermal vents and subterranean aquatic system (stigobionts). A few have no gut and acquire adequate nutrients through osmotrophism and/or engaging symbiotic microbes. In the absence of exoskeleton to escape predation, the 17,000 speciose annelids have explored bewildering modes of reproduction; not surprisingly, 42-47% of them are brooders. With 13,000 species, polychaetes are gonochores but some 207 species of them are hermaphrodites. Clitellates are all hermaphrodites; of them, 76 species are parthenogens, of which 56 are earthworms. Regenerative potency of annelids ranges from an organ to an entire worm from a single 'seminal' segment. The head, tail and both together can be regenerated 21, 42 and 20 times, respectively. However, the potency is limited to ~1% of polychaetes and < 2% of oligochaetes. In oligochaetes, the chloragogue temporally separates regeneration and reproduction but sedentary polychaetes undertake them together at the reduced reproductive output. Only 79 polychaete and 111 oligochaete species have the potency for clonal reproduction. Within families, the potency ranges from 2% in spionids to 54% in naidids. Epitoky, a spectacular and unique phenomenon, involves the transformation from benthic to meroplanktonic reproductive morphism. It occurs in 106 errant polychaete species. The larger glycerides, nereidids and eunicids use muscular energy to climb < 50 m vertical distance. But the small phyllodocids and cteniodrilids may reduce buoyancy to climb 1,000-4,000 m vertical distance. Heterogamatic sex determination is reported to occur only in six polychaete species, although karyotype is known for 83 annelid species. In temperate polychaetes, a dozen neuroendocrines, arising mostly from the 'brain' regulates reproductive cycle. A complete chapter devoted to vermiculture, (i) recognizes the fast-growing candidate species, (ii) distinguishes 'layers' from 'brooders', (iii) indicates that the harvest of oligochaetes may reduce the input of nitrogenous fertilizer in the ricefield, and (iv) explores the scope for increasing wealth from waste.

The history of pathogens and vectors, unique symptoms of diseases and economic importance of important viral diseases have been dealt with in the introductory chapter of this book. While highlighting the role of arthropods, nematodes, and fungi; other agents of the spread of plant pathogens have also been included. Important aspects of insect vectors with direct bearing on transmission, i.e. vector identification, biology, feeding apparatus, and mechanism of spread including control of pathogens through vectors are covered comprehensively. As aphids and other hemipterous insects are major insect vectors, the book stresses on this order. There is a focus on the transmission of determinants under different categories of the transmission mechanism. The transmission determinant paradigm comprising coat protein and helper component has been expounded with recent cases. A brief description of new diseases at least one from each genus of plant viruses has been included in this compendium to elucidate the interaction of vector and virus. Phytoplasmal etiology of pathogens has been detailed separately on account of their importance. The transmission of plant viruses through insects with biting and chewing type of mouth parts has been discussed in detail as separate chapter. The latest research in the field of mites, nematodes, and fungi as vectors of plant viruses has been included. How the phytotoxemia is different from other crop disorders, has been critically explained with support from suitable and common examples of crop disorders. The book also highlights the effects of plant viruses on their vectors. An account of classification of plant viruses has also been given for better understanding of subject matter. Likewise, the information on the electron microscope along with its use has been included so as to define the procedure of examining sub-microscopic entities. The latest developments in the management of plant pathogens through vector management have been discussed with special reference to the use of biotechnology, crop protection, and plant resistance. The book will be of value to the teachers and to researchers. It will also be useful for extension workers in managing crop disorders. Students and researchers of entomology, plant pathology, plant protection and virology disciplines will obtain the latest in the field, through this book.

This book recounts the habits of many interesting and unusual exceptions to the rule that insects are typically terrestrial forms of life. It examines the different ways that groups of species have developed modes of existence in or on the surface of water, and gives reasons why the gross morphology of insects is not favorable for life in or near bodies of water, such as wings that fail to function after coming into contact with water, rendering them useless.

Insects have evolved very unique and interesting tactics using chemical signals to survive. Chemical ecology illustrates the working of the biological network by means of chemical analyses. Recent advances in analytical technology have opened the way to a better understanding of the more complicated and abyssal interactions of insects with other organisms including plants and microbes. This book covers recent research on insects and chemical communications and presents the current status about challenges faced by chemical ecologists for the management of pests in agriculture and human health.
