The phylum Platyhelminthes is constituted of about 50,000 species of flatworms, most of which are parasites of vertebrates, but many living freely in a wide variety of habitats from the deep-sea to the damp soils of tropical forests. They are, at least superficially, morphologically simple and have been considered the most primitive of multi-cellular animals. This book elucidates the position of the flatworms in the animal kingdom and the radiation of free-living and parasitic groups, by the use of established and modern systematic techniques.

First Published in 1989, this book explores the relationship between plants and insects and the ways in which they interact with each other. Carefully compiled and filled with a vast repertoire of notes, diagrams, and references this book serves as a useful reference for students of oncology, and other practitioners in their respective fields.

Heteropterans regularly cause a wide variety and large number of problems for humans - at times on a catastrophic scale. The 37,000 described species of this suborder including many pests, disease transmitters, and nuisances exist worldwide, inflicting damage on crops, forests, orchards, and human life. Inspired by the widespread economic impact of this activity, Heteroptera of Economic Importance presents the most thorough, detailed account of true bugs to date, from the bloodsucking bed bug to the dreaded assassin bug. It is the definitive source for biological information not only on true bugs of economic importance, but on the general biology of the major families of Heteroptera as well.

Heteroptera of Economic Importance integrates the best of insect-focused and crop-oriented references, synthesizing the biology, behavior, and ecology of the true bugs. Each entry includes a detailed life history, helping you to evaluate the impact of harmful and useful Heteroptera. The thorough, comprehensive bibliographies support further research. Separate indices to insects and plants let you adapt the book to your use. It covers the physiology of plant damage and predation by this cosmopolitan group. This coverage, along with information on control measures and natural enemies, helps you evaluate and compare the best methods of management.

Heteroptera can be serious crop pests, harmful to humans, or can be valuable as biological control agents. This work discusses them individually, with expert presentation of the biology, distribution, damage, and control of each economically significant insect. As a resource that lets you easily access information and research on related bugs globally, Heteroptera of Economic Importance lends itself to sharing of ideas and information across geographical boundaries which will inevitably yield more research, new ideas, and better control.

The Ichneumonoidea is a vast and important superfamily of parasitic wasps, with some 60,000 described species and estimated numbers far higher, especially for small-bodied tropical taxa. The superfamily comprises two cosmopolitan families - Braconidae and Ichneumonidae - that have largely attracted separate groups of researchers, and this, to a considerable extent, has meant that understanding of their adaptive features has often been considered in isolation. This book considers both families, highlighting similarities and differences in their adaptations. The classification of the whole of the Ichneumonoidea, along with most other insect orders, has been plagued by typology whereby undue importance has been attributed to particular characters in defining groups. Typology is a common disease of traditional taxonomy such that, until recently, quite a lot of taxa have been associated with the wrong higher clades. The sheer size of the group, and until the last 30 or so years, lack of accessible identification materials, has been a further impediment to research on all but a handful of lab rat species usually cultured initially because of their potential in biological control. New evidence, largely in the form of molecular data, have shown that many morphological, behavioural, physiological and anatomical characters associated with basic life history features, specifically whether wasps are ecto- or endoparasitic, or idiobiont or koinobiont, can be grossly misleading in terms of the phylogeny they suggest. This book shows how, with better supported phylogenetic hypotheses entomologists can understand far more about the ways natural selection is acting upon them. This new book also focuses on this superfamily with which the author has great familiarity and provides a detailed coverage of each subfamily, emphasising anatomy, taxonomy and systematics, biology, as well as pointing out the importance and research potential of each group. Fossil taxa are included and it also has sections on biogeography, global species richness, culturing and rearing and preparing specimens for taxonomic study. The book highlights areas where research might be particularly rewarding and suggests systems/groups that need investigation. The author provides a large compendium of references to original research on each group. This book is an essential workmate for all postgraduates and researchers working on ichneumonoid or other parasitic wasps worldwide. It will stand as a reference book for a good number of years, and while rapid advances in various fields such as genomics and host physiological interactions will lead to new information, as an overall synthesis of the current state it will stay relevant for a long time.

Zooplankton is a major work of reference for researchers in plankton biology, physiology and behavior, which combines behavioral and psychological approaches to the study of plankton on present and interdisciplinary investigation of sensory processes in pelagic environments. The breadth of perspective thus achieved provides valuable insights into the larger scale ecological processes of biological productivity, community structure and population dynamics.
Technological advances in almost all aspects of biological research have opened up opportunities for a re-examination of the sensory ecology of planktonic organisms. In this wide-ranging collection, leading researchers in planktonic behavior and physiology address the rapidly developing interface between these two major areas. The studies presented range from the laboratory to the field and from the cell to the whole organism, but share the common goal of understanding the special sensory world of organisms that live in pelagic environments and how their behavior and physiology relate to it.

Bees are critically important for ecosystem function and biodiversity maintenance through their pollinating activity. Unfortunately, bee populations are faced with many threats, and evidence of a massive global pollination crisis is steadily growing. As a result, there is a need to understand and, ideally, predict how bees respond to pollution disturbance, to the changes over landscape gradients, and how their responses can vary in different habitats, which are influenced to different degrees by human activities. Modeling approaches are useful to simulate the behavior of whole population dynamics as well as to focus on important phenomena detrimental to bee-life history traits. They also allow simulation of how a disease or a pesticide can impact the survival and growth of a bee population. In Silico Bees provides a collection of computational methods to those primarily interested in the study of the ecology, ethology, and ecotoxicology of bees. The book presents different cases studies to enable readers to understand the significance and also the limitations of models in theoretical and applied bee research. The text covers modeling of honey bee society organization, infectious diseases in colonies, pesticide toxicity, chemical contamination of the hive, and more. Written by an international team of scientists, this book is of primary interest to those whose research or professional activity is directly concerned with the study of bees. It is also intended to provide graduate and post-graduate students with a clear and accessible text covering the main types of modeling approaches that can be used in terrestrial ecology and ecotoxicology.

This is a comprehensive textbook covering all aspects of entomology in the human environment. There is particular emphasis on control and biology of pests.

In the English edition of his landmark book Endosymbiosis of Animals with Plant Microorganisms (1965), Professor Paul Buchner, probably the most prominent founder of systematic symbiosis research, wrote: "I too soon fell victim to the spell of this subject, and from 1911 on devoted myself to it." Almost half a century later, a growing number of entomologists are recognizing the impact that arthropod-bacteria symbiosis has on virtually all aspects of the biology of both host and symbiont. The discussion of this subject tends to be system based, with primary emphasis on the insect host. However, recent screening studies have revealed that the diversity of bacteria associated with arthropods may not be as wide as initially expected, and some genera are constantly being found in hosts that belong to distantly related taxa. Manipulative Tenants: Bacteria Associated with Arthropods introduces the fascinating world of bacteria-arthropod associations with an emphasis on the bacterial partner. Written by an interdisciplinary team of international contributors, this book provides an overview of the diversity of bacterial symbionts identified to date as frequent partners of terrestrial arthropods. It discusses primary (obligatory) symbionts as well as the most abundant secondary (facultative) symbionts currently known. Summarizing the most up-to-date information available on each symbiont, the book presents a synopsis of the field from the bacterial angle. Chapters examine Proteobacteria, including Sodalis and Wigglesworthia in tsetse flies and Stammerula and other symbiotic bacteria in fruit flies, as well as Bacteroidetes such as Blattabacterium and Cardinium. The book also identifies questions that emerge from the study of these systems. This comprehensive reference introduces the topic of bacteria-arthropod associations to researchers who are not familiar with it, enlarges the scope of knowledge of those who are, and provides a textbook for students in microbiology and other branches of biology. Key selling features: Combines entomologists' and microbiologists' perspectives to create a full picture of complex systems Discusses dramatic differences in structure and behavior between some symbiotic bacteria and autonomous bacteria Examines the influence of symbiotic bacteria on the evolution of their hosts Includes diagrams, tables, graphs, pictures, and extensive references Emphasizes potential applications of symbiotic bacteria for solving agricultural and medical problems

Juvenile hormones (JHs) are a group of structurally related sesquiterpenes secreted by the insect corpora allata. They affect most insect life-cycle stages and physiological functions, including embryogenesis, larval and adult development, metamorphosis, reproduction, metabolism, diapause, polyethism, and migration. Juvenoids such as methoprene, hydroprene, kinoprene, pyriproxyfen, and fenoxycarb are man-made chemicals that mimic the structure and/or activity of JHs, selectively targeting and disrupting the endocrine system of insects. They are particularly suited as larvicides for the control of pest and disease vectoring insects such as mosquitoes. Juvenile Hormones and Juvenoids: Modeling Biological Effects and Environmental Fate discusses the various modeling approaches that can be used to study the mechanism of action of JHs in insects and to estimate the adverse effects and the environmental fate of the juvenoids that mimic their activity. This book is the third of the QSAR in Environmental and Health Sciences series, but the first dedicated to the use of QSAR and other in silico techniques to provide these insights into JHs and their analogs. With contributions by an international team of scientists, the book begins with a historical survey of JHs and juvenoids. It then discusses biosynthesis of sesquiterpenoids followed by chapters covering JH activity such as morph-specific JH titers in crickets, and JH analog activity including soldier-specific organ development in termites and the role of methoprene in gene transcription. The book examines modeling approaches applied to resistance to JH analogs, to population dynamics of nontarget species in the presence of juvenoids, and to SAR and QSAR of JH mimics. The book concludes with a discussion on the use of multicriteria analysis for selecting insecticides for vector control.

The book goes on to consider the factors affecting snail populations and possible methods for population control.

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.

This book is devoted to the ichnology of insects, and associated trace fossils, in soils and paleosols. The traces described here, mostly nests and pupation chambers, include one of the most complex architectures produced by animals. Chapters explore the walls, shapes and fillings of trace fossils followed by their classifications and ichnotaxonomy. Detailed descriptions and interpretations for different groups of insects like bees, ants, termites, dung beetles and wasps are also provided. Chapters also highlight the the paleoenvironmental significance of insect trace fossils in paleosols for paleontological reconstructions, sedimentological interpretation, and ichnofabrics analysis. Readers will discover how insect trace fossils act as physical evidence for reconstructing the evolution of behavior, phylogenies, past geographical distributions, and to know how insects achieved some of the more complex architectures. The book will appeal to researchers and graduate students in ichnology, sedimentology, paleopedology, and entomology and readers interested in insect architecture.
