Literature on the population dynamics of insect herbivores tends to favour a top-down regulation of abundance, owing much to the action of natural enemies. Originally published in 2005, this volume challenges this paradigm and argues that tree-dwelling species of aphids, through competition for resources, regulate their own abundance. The biology of tree-dwelling aphids is examined, particularly their adaptation to the seasonal development of their host plants. When host-plant quality is favourable, aphids, by telescoping generations, can achieve prodigious rates of increase which their natural enemies are unable to match. Using analyses of long-term population censuses and results of experiments, this book introduces students and research workers to insect herbivore-host dynamics using the interaction between aphids and trees as a model.

Originally published in 1925, this volume is adapted from lectures delivered by the author at the Royal Institution during the Christmas period of 1924. Its aim was principally to engage the interest of young people and provide them with the tools for increasing their own knowledge through methodical, scientific research. In this spirit, descriptions of the life histories of various insects are avoided in favour of explanations for how these life histories were worked out. Numerous illustrative figures of insects and insect habitats are also included. This is a highly readable and informative text that will be of value to anyone with an interest in entomology, natural history, and the history of education.

Drosophila is the scientist's favourite lab organism because it reproduces quickly and has straightforwartd chromosomes. It has long been the organism of choice in experiments in genetics and is also popular in developmental and behavioural studies. The second edition of this popular Practical Approach book brings the methodology up to date, with contributions from the world's leading Drosophila researchers. It will be valuable to the novice and experienced worker alike.

Spiders are often underestimated as suitable behavioural models because of the general belief that due to their small brains their behaviour is innate and mostly invariable. Challenging this assumption, this fascinating book shows that rather than having a limited behavioural repertoire, spiders show surprising cognitive abilities, changing their behaviour to suit their situational needs. The team of authors unravels the considerable intra-specific as well as intra-individual variability and plasticity in different behaviours ranging from foraging and web building to communication and courtship. An introductory chapter on spider biology, systematics and evolution provides the reader with the necessary background information to understand the discussed behaviours and helps to place them into an evolutionary context. Highlighting an under-explored area of behaviour, this book will provide new ideas for behavioural researchers and students unfamiliar with spiders as well as a valuable resource for those already working in this intriguing field.

The hardback edition of this was the first book on insect flight since J W S Pringle's classic Insect Flight was published in 1957. Much has been written since on applied and ecological aspects of flight, but the question of the origin of wings and flight, their structural concomitants, and the related aerodynamical issues have been confined largely to armchair speculation in a scattered literature. This book is written by a leading authority on insect flight, and for the first time draws a coherent, empirically based picture of how insect flight may have evolved. Following excellent reviews the book is now being made available in paperback.

The formation of galls - abnormal growths or swelling in a plant - may be induced by infection of the plant by bacteria or fungi, or attack from certain mites, nematodes or insects. This book provides comprehensive coverage of the biology of galls and their complex ecological etiology. The expert contributors address topics such as the effect of insect secretions on plant growth, the evolution and physiology of gall-inducing insects, patterns in gall development and induction, the role of nutritive cells, and many other key issues. This valuable work in cecidology will interest all biologists and botanists concerned with plant health, and entomologists working in the field of plant-insect relationships.

A mutualism is an interaction between individuals of two different species of organism in which both benefit from the association. With a focus on mutualisms between ants and aphids, coccids, membracids and lycaenids, this volume provides a detailed account of the many different facets of mutualisms. Mutualistic interactions not only affect the two partners, but can also have consequences for higher levels of organization. By linking theory to case studies, the authors present an integrated account of processes and patterns of mutualistic interactions at different levels of organisation, from individuals to communities to ecosystems. Interactions between ants and their insect partners and their outcomes are explained from a resource-based, cost-benefit perspective. Covering a fascinating and growing subject in modern ecology, this book will be of interest to community and evolutionary ecologists and entomologists, at both research and graduate student level.

This book presents current research on all types of ant-plant interactions, and concentrates on understanding these often complex relationships in evolutionary and ecological terms. The range of interactions varies from herbivory (leaf-cutter ants) to complex symbiosis. Many ants prey on plant pests, thus protecting the plant from harm, receiving in exchange nectar and/or nest sites. In some cases the ants tend and protect other insects such as butterfly larvae or Homopterans (which include the aphids and cicadas) which may benefit the ants at the expense of both the host plant and the other insects. Some ants are known to be seed dispersers, and in at least one plant (cocoa) they appear to affect rates of pollination. A significant proportion of these interactions exhibit a high degree of mutualism, making this book part of a growing literature on the ecological determinants of mutualistic behaviour. The thirty-seven chapters by more than fifty contributors range in geographical coverage from northern and southern temperate zones, to the New World tropics, to Australia and south-east Asia. The emphasis throughout, even in the more descriptive chapters, is on possible explanations for observed phenomena. Workers in ecology, evolution, and behaviour will welcome this compendium of information on a subject that has become a modern testing-ground for evolutionary ecology.

Comprising well over half of all known animal species, insects are the most successful organisms on the planet. Indeed, it is no exaggeration to say that one cannot study agriculture, biology, and the environment, without a basic understanding of entomology. Furthermore, insects are indispensable to advances in molecular biology and genetics, and their ongoing decline in many parts of the world has stimulated much research in the crucial roles they play in global ecosystems. However, the sheer diversity of insects can be a challenge to every newcomer to entomology. Most entomology textbooks tend to focus on insect biology, leaving readers with only a superficial idea of insect diversity and evolution, while others delve into too much detail that will deter the novice. In contrast, Essential Entomology has a clear taxonomic structure that provides readers with the necessary framework to understand the diversity, life history, and taxonomy of insects in a new light. This fully revised edition provides the most up-to-date guide to insects and includes all the major developments in molecular biology and palaeontology of the last 20 years. This textbook is an essential read for undergraduate and graduate students taking courses in entomology, agriculture, and forestry. It will also appeal to a broad academic audience of ecologists, conservationists, natural resource managers, as well as to the far more numerous general readers who are interested in wildlife, nature, and the environment. With these diverse audiences in mind, the straightforward and accessible style of the first edition has been maintained, technical jargon has been kept to a minimum, and sufficient background information is provided to enable the reader to follow the text with ease.

A systematic treatise on the Chrysididae, a globally distributed family of wasps, also known as gold wasps (for their bright metallic colours) or cuckoo wasps (for their parasitic habits). Some 3,000 valid species have been named and are arranged in 84 genera and 4 sub-families. This book is the first re-evaluation of their taxonomy since 1889 and its four main goals are: to provide a worldwide overview of the family, with re-classification of the generic and higher taxa; to summarize previously published information; to indicate problems in need of further study; to give detailed synonymic species lists for each genus, where synonymy refers to scientific names used in different nomenclature systems to designate the same species. Discussions for each tribe and sub-family include ancestral characteristics, phylogenetically important characters and a corresponding cladogram, keys to genera, and relationships amongst taxa. Generic discussions include generic synonymy and diagnostic features, relationships to other genera, and detailed species lists. The book should be of interest to entomologists, taxonomists and systematists, especially in academic departments, natural history museum

In this extensive update of his definitive reference, Charles D. Michener reveals a diverse fauna that numbers more than 17,000 species and ranges from the common honeybee to rare bees that feed on the pollen of a single type of plant. With many new facts, reclassifications, and revisions, the second edition of The Bees of the World provides the most comprehensive treatment of the 1,200 genera and subgenera of the Apiformes. Included are hundreds of updated citations to work published since the appearance of the first edition and a new set of plates of fossil bees.

The book begins with extensive introductory sections that include bee evolution, classification of the various bee families, the coevolution of bees and flowering plants, nesting behavior, differences between solitary and social bees, and the anatomy of these amazing insects. Drawing on modern studies and evidence from the fossil record, Michener reveals what the ancestral bee -- the protobee -- might have looked like. He also cites the major literature on bee biology and describes the need for further research on the systematics and natural history of bees, including their importance as pollinators of crops and natural vegetation. The greater part of the work consists of an unprecedented treatment of bee systematics, with keys for identification to the subgenus level. For each genus and subgenus, Michener includes a brief natural history describing geographical range, number of species, and noteworthy information pertaining to nesting or floral biology.

The book is beautifully illustrated with more than 500 drawings and photographs that depict behavior, detailed morphology, and ecology. Accented with color plates ofselect bees, The Bees of the World will continue to be the world's best reference on these diverse insects.

This book presents the whole picture of the ecological and evolutionary study on the ground beetle group, the subgenus Ohomopterus of the genus Carabus, endemic to Japan. This flightless beetle group consists of many geographic races. They show divergence in key traits for reproductive isolation-body size and genital morphology, which leads to coexistence of two or more species. This beetle group provides an important material to study how a lineage of organisms diversify and form multi-species assemblage, and thereby multiply their species richness. The book introduces novel genomic approaches to resolve questions about evolution of Ohomopterus. The readers will find that this story of evolution in Carabus beetles revealed by recent approaches is much different from what was told in previous literature. Exploring different cases across a wide range of lineages is important in constructing a synthetic theory of species radiation and richness, including speciation and species coexistence. This study on Ohomopterus beetles contributes to the ongoing discussion to understand how and why species multiply and how species richness increases in one area of our planet.

How is the staggering biodiversity of the parasitoid insects maintained? This book, first published in 1994, explores patterns in host-parasitoid interactions, including parasitoid community richness, the importance of parasitoids as mortality factors, and their impact on host densities as determined by the outcomes of parasitoid introductions for biological control. It documents general patterns using data sets generated from the global literature and evaluates potential underlying biological, ecological and evolutionary mechanisms. A theme running throughout the book is the importance of host refuges as a major constraint on host-parasitoid interactions. Much can be learnt from the analysis of broad patterns; a few simple rules can go a long way in explaining the major components of these interactions. This book will be an invaluable resource for researchers interested in community ecology, population biology, entomology and biological control.

Ethical issues, intellectual property rights, regulation policies in various countries related to agricultural biotechnology are examined. The rapid developments in plant biotechnology are explained to a large audience with relevant examples. New varieties of crops can be adapted to new climatic conditions in order to reduce pest-associated losses and the adverse abiotic effects

Arctic and Subarctic North America is particularly affected by climate change, where average temperatures are rising three times faster than the global average. Documenting the changing climate/environment of the north requires a structured knowledge of indicator taxa that reflect the effects of climate changes.Aleocharine beetles are a dominant group of forest insects, which are being used in many projects as indicators of environmental change. Many species are forest specialists restricted to certain microhabitats, some are generalists and others are open habitat specialists. They represent many ecological niches and, as such, are good indicators for many other species as well. The majority of Canadian aleocharine beetle species (about 600 spp.) has been studied and published by Jan Klimaszewski et al. (2018, 2020), mainly from southern, central, and western Canada, while the northern taxa remain poorly known and documented. The aim of the present book is to summarize the knowledge on this insect group in the Arctic and Subarctic North America and to provide a diagnostic and ecological tool for scientists studying and monitoring insects in northern Canada and Alaska. The book includes a review of the literature, information on 238 species and their habitats, taxonomic review, images, and identification tools.

This atlas presents a concrete tool to identify xylophagous activity by the remains they left in wooded areas in Western Europe. Xylophagous insects are among the largest predators of woody tissues. They leave discriminating traces, different for each species according to their bioecology, and so it is necessary to know how to recognize and characterize them. The book is a practical tool to help identify and interpret them through a standardized presentation of the most ubiquitous families and a key to their determination. It presents descriptions of the galleries and of morphometry of the faecal pellets based on macroscopic features for xylophagous identification, and includes information about the origin and distribution of the xylophagous biological cycles, bioclimatic conditions and bioecology, and the type of woods that are attacked. The book will be a useful guide for forest managers, heritage conservationists, environmental engineers, bioarchaeologists, entomologists, loggers, and wood anatomists.
