Ladybirds are probably the best known predators of aphids and coccids in the world, though this greatly underestimates the diversity of their biology. Maximising their impact on their prey is an important element in modern conservation biological control of indigenous natural enemies in contrast to the classical approach of releasing alien species. Ivo Hodek is one of the most internationally respected experts on coccinellids who has researched these insects for his entire career. He has now brought together 14 scientists of international standing to author 12 chapters, making this book the definitive treatment of coccinellid biology and ecology. This volume covers the rapid scientific developments of recent years in the understanding of coccinellid phylogeny, the semiochemicals influencing their behaviour and of molecular genetics. Recent insights in relation to intraguild predation and the assessment of the predatory impact of coccinellids are also covered. Other special features of the volume are the extensive references covering the literature from both East and West and a taxonomic glossary of the up-to-date nomenclature for species of coccinellids as well as of other organisms mentioned in the text. While aimed at researchers, university teachers and agricultural entomologists, the book is readable and appropriate for others who just have a liking for these interesting and attractive insects.

Over the last five decades pesticides have undoubtedly helped to increase agricultural production and control vectors of disease, however the environmental impact of long term agro-chemical use has been cause for concern along with the effects on human health. In Pesticides, Graham Matthews begins by looking at the developmental history of pesticides, and how crop protection was achieved before they were in use, how pesticides are registered for use and what happens to pesticides in food and the environment. Pesticide application and operator safety is investigated and the future of pesticides in light of the development of genetically modified crops is explored. Provides commercially important information for the agro-chemical industry Addresses all aspects of public concern relating to human health and the environment, including spray drift, bystander, resident and worker exposure Looks at the future of pesticides in light of the increasing prevalence of genetically modified crops Collecting together the most recent research in the area in a single volume, this book is a vital resource for agricultural scientists, agronomists, plant scientists, plant pathologists, entomologists, environmental scientists, public health personnel, toxicologists, crop protection personnel and all those involved in the agrochemical industry and government pesticide registration and legislation.

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.

This established, popular textbook provides a stimulating and comprehensive introduction to the insects, the animals that represent over half of the planet's biological diversity. In this new fourth edition, the authors introduce the key features of insect structure, function, behavior, ecology and classification, placed within the latest ideas on insect evolution. Much of the book is organised around major biological themes - living on the ground, in water, on plants, in colonies, and as predators, parasites/parasitoids and prey. A strong evolutionary theme is maintained throughout. The ever-growing economic importance of insects is emphasized in new boxes on insect pests, and in chapters on medical and veterinary entomology, and pest management. Updated 'taxoboxes' provide concise information on all aspects of each of the 27 major groupings (orders) of insects. Key Features: All chapters thoroughly updated with the latest results from international studies Accompanying website with downloadable illustrations and links to video clips All chapters to include new text boxes of topical issues and studies Major revision of systematic and taxonomy chapter Still beautifully illustrated with more new illustrations from the artist, Karina McInnes A companion resources site is available at www.wiley.com/go/gullan/insects. This site includes: Copies of the figures from the book for downloading, along with a PDF of the captions. Colour versions of key figures from the book A list of useful web links for each chapter, selected by the author.

Much of our understanding about insect predator-prey dynamics has been due to studies on insect parasitoids. But do true predators such as ladybird beetles really operate in a similar way and how does this affect their use in biological control? The extensive literature on ladybirds as biocontrol agents shows that their size and rate of development is very dependent on the nature of their prey. This volume explores basic ladybird biology, their association with their prey and its effect on development rate and body size. Optimal foraging theory, field observations and laboratory experiments are used to illustrate how ladybird larvae maximise their rate of energy intake, and ladybird adults their fitness. The interdependence of these life history parameters is then used to develop a simple predator-prey model which, with an analysis of the literature, highlights the specific attributes of potentially successful biocontrol agents for all those interested in predator-prey dynamics.
