Egg Parasitoids in Agroecosystems with emphasis on Trichogramma was conceived to help in the promotion of biological control through egg parasitoids by providing both basic and applied information. The book has a series of chapters dedicated to the understanding of egg parasitoid taxonomy, development, nutrition and reproduction, host recognition and utilization, and their distribution and host associations. There are also several chapters focusing on the mass production and commercialization of egg parasitoids for biological control, addressing important issues such as parasitoid quality control, the risk assessment of egg parasitoids to non-target species, the use of egg parasitoids in integrated pest management programs and the impact of GMO on these natural enemies. Chapters provide an in depth analysis of the literature available, are richly illustrated, and propose future trends.

Pests cause economic damage to crop and stored products, while vectors are responsible for transmission of disease-causing agents in human beings and livestock. Application of synthetic pesticides in agriculture though has given immediate relief but has also caused well known side effects, leading to a consensus among entomologists and agriculturists to shift towards other ecofriendly pest management. Insect natural enemies consisting of predators, parasitoids and pathogens have attracted the attention of scientists across the globe. These natural enemies exist in agroecosystems and suppress the populations of pests. Parasitoids are farmers' friends and most successful group of natural enemies. Highly specialized in their host choice, female parasitoid searches for a suitable host to lay eggs and larvae in or on or near the hosts. Exploiting this potency of parasitoids may yield successful results in controlling notorious pests in an ecofriendly way. This book covers information on the important biocontrol agents effective in pest suppression. It starts with insect parasitic groups followed by specific group of parasitoids. It is hoped that the book presents a comprehensive account of beneficial parasitoids and will be useful to Undergraduate and Postgraduate students of Entomology, Biological Control, Plant Protection, Agricultural Zoology and Zoology, besides those involved in competitive examinations and policy planning. Features Each chapter has been written by specialized senior persons. Every chapter contains Learning Objectives and Points to Remember. This book offers comprehensive knowledge of parasitoids and their application in pest management in a lucid way.
The nature and diversity of presentations at the second International Conference on Insect Neurochemistry and Neurophysiology (ICINN--86) held at the University of Maryland on August 4-6. 1986, attest to the vital ity and broad scope of research in insect neuroscience. The present vol ume is a written account of the invited lectures, contributed papers, and posters presented at the conference, and as such, serves as a fair indica tor of the trends in current research in this field here and abroad. The principal portion of this book consists of seven review papers that were presented by invited speakers. Although the topics vary wide ly, they reflect on and emphasize the main theme of the conference, i. e., the nature and function of molecular messengers that communicate be meen the central nervous system and organs or tissues involved in the growth, development, reproduction, and behavior of insects. This empha sis is continued in the following three sections on neurochemistry, neuro physiology, and neuroanatomy, although no conscious effort was made by the organizers to highlight these particular fields of neuroscience. It is evident that the recent advances in both physical and chemical analyti cal techniques have made possible the acquisition of structurally defined probes, the long sought-after tools for unraveling the secrets of endogen ous communication. Each section of short papers derived from the oral and poster presentations at the conference is prefaced by an overview that highlights and summarizes the section's content."

This 4th edition updates the latest research on earthworms. More than 3,000 species of earthworm exist in the world. They are considered to be an important ally in advancing environmental and biomedical research. Earthworms play an important role in forest or agricultural ecosystems and play an increasing role in biomedical issues. Earthworms are critical to the environment because they consume huge quantities of decomposed litter, manure, and other organic matter deposited on soil -- helping to convert it into rich topsoil Earthworms can also help reduce soil compaction, improve permeability--thus providing channels for root growth, water infiltration, and gas exchange. Earthworms are also important animals for the assessment of the toxicity of chemicals, such as herbicides and pesticides, which are deliberately released into the environment. Earthworms are superb barometers' or sentinels' providing an early warning of deterioration in soil quality.
Allen im Vorwort zu Band I und II angefuhrten Damen und Herren danke ich nochmals herzlich und ganz besonders auch wieder der Deutschen Forschungsgemeinschaft fur ihre Hilfe. Ganz besonderen Dank auch wieder meiner lieben Frau, die mir unentwegt zur Seite stand und meinem lieben Freund Dr. Alfred KALTENBACH, der mir die Bearbeitung der Mantodea abnahm und sie vorzuglich durchfuhrte, und meinem verehrten Freund, Prof. Dr. Erwin SCHIMITSCHEK, Wien fur seine Hilfe, sowie meinen lieben Freunden Patricia HOLMES, Bir- mingham, und Michael SAMWAYS, London, fur die Durchsicht der englisc4en Manuskri ptteile. Weil sich die Gelegenheit bot in einer Sammlung Neotypen fur verschollene Typen einzusetzen, habe ich dies getan; naturlich nicht um des Neotypus willen, sondern um einwandfreies Vergleichs- material sicherzustellen, denn es hat sich doch wiederholt ergeben, dass seither als einwandfrei betrachtete Arten mit fortschreitender Untersuchungstechnik und Verhaltensstudien sich plotzlich in einige Arten aufspalten liessen. Selbstverstandlich habe ich mich zuvor in Rundschreiben an viele Kollegen in Europa nach dem Typenverbleib erkundigt und dann Neotypen von einem dem locus typicus moglichst nah liegendem Fundort eingesetzt. Wenn diese Neotypen nicht im- mer "Ausnahmefalle" im Interesse der Stabilitat der Nomenklatur waren, wie sie die "International Commission on Zoological Nomen- dature" vorschreibt, so geschah dies aus dem angefuhrten Grund; eines Tages mogen sie sich doch als nutzlich erweisen. Sie befinden sich alle samt allen Typen, Allotypen und Para typen mit meiner ganzen Sammlung im Museum d'Histoire Naturelle Geneve/Genf.
Updated and much expanded, the Second Edition of Parasitic Protozoa is designed to be useful to physicians, veterinarians, and research scientists concerned with diseases caused by protozoa in man, and in domestic and wild animals including fish, mollusks and insects, as well as the more commonly considered vertebrate animals. Each section contains information on disease pathogens, treatment, diagnosis, and epidemiology of the diseases caused by the various protozoans. The book is not limited to these medically-oriented subjects, but treats taxonomy, morphology, and metabolism of the organisms in such a way as to be of interest to scientists and graduate students working in the field of protozoology. The entire edition, published in ten volumes, is arranged so that subjects of common interest occupy individual volumes.
A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world's leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.
This version of the book is fully illustrated and contains over a hundred photographs in black & white. Moths of the Limberlost is a fascinating book written by the well-known American novelist and photographer Gene Stratton-Porter. It paints a vibrant picture of her delight in the moths as she loves, cares for, breeds and studies the creatures. The first chapter is an introduction and the second is an overview of the natural history of moths, however, it is only marginally technical and she interweaves the chapter with her own experiences. In the final thirteen chapters she focuses on one moth per chapter, the moths that have most caught her interest. It is partly an autobiography as she describes her experiences from childhood - her delights and joys at successfully breeding them or learning something new about them and her sadness when they die or don't breed. It describes her family's help in this passion and the friends she gained through the pursuit. It is a beautiful window into the person she was and her love of nature.

Enter a hidden world of snail killers, silly names and crazy sex in The Secret Life of Flies. Entomolologist Erica McAlister dispels many common misconceptions and reveals how truly amazing, exotic and important these creatures really are. From hungry herbivores and precocious pollinators to robberflies, danceflies and the much maligned mosquito, McAlister describes the different types of fly, their unique and often unusual characteristics, and the unpredictable nature of their daily life. She travels from the drawers of wonder at the Natural History Museum, to piles of poo in Ethiopia, via underground caves, smelly latrines and the English country garden. She discovers flies without wings, rotating genitalia and the terrible hairy fly, while pausing along the way to consider today's key issues of conservation, taxonomy, forensic entomology and climate change. Combining her deep knowledge and love of flies with a wonderful knack for storytelling, Erica McAlister allows us to peer - amazed and captivated - into the secret life of flies.
This collection features four peer-reviewed reviews on integrated pest management (IPM) in cereal cultivation. The first chapter describes a holistic approach to IPM using knowledge of the natural regulation of herbivore and weed populations and of natural succession in agricultural wetlands. It also highlights the need for an improved understanding of rice ecosystems in a holistic manner to ensure the economic and environmental sustainability of rice production. The second chapter provides a brief overview of IPM and reviews the range of control methods available to growers, including biological, cultural and chemical. The chapter considers the implementation of IPM programmes in wheat production and utilises a case study from New Zealand to demonstrate a successful example of it. The third chapter discusses key insect pests of sorghum, their life cycles and their impact on crop productivity and performance. The chapter reviews the use of IPM programmes as a sustainable alternative to controlling pest infestations without the need for insecticides. The final chapter examines host plant resistance as an ecological approach to managing crop pests and considers the process of evaluating resistance on the basis of insect behavior. The chapter also looks at breeding rice for resistance to insect pests and considers the constraints on the development and deployment of insect-resistant plant technology.
On rocky coastlines, receding tides leave standing pools that have long held a fascination for the amateur seashore naturalist, revealing glimpses of colourful and curious marine plants and animals. Animal diversity is far greater in the sea than in terrestrial or freshwater habitats, and the hugely varied fauna of rock pools reflects that fact. Rock pools also undergo dramatic shifts in temperature, salinity and pH, making such habitats crucibles of adaptation and change. This Naturalists' Handbook offers a comprehensive introduction to this captivating world, with chapters covering rock-pool ecology, seaweeds, animals, identification and guidelines for possible fieldwork and further study. Also presented are detailed keys to all the main groups likely to be encountered when rockpooling around Britain and Ireland - from sea squirts to chitons, from anemones to sea spiders, from amphipods to fishes. Rock pools is an indispensable tool in discovering these kaleidoscopic habitats and their multitudinous inhabitants.

In medical and health care the scientific method is little used, and statistical software programs are experienced as black box programs producing lots of p-values, but little answers to scientific questions. The pocket calculator analyses appears to be, particularly, appreciated, because they enable medical and health professionals and students for the first time to understand the scientific methods of statistical reasoning and hypothesis testing. So much so, that it can start something like a new dimension in their professional world. In addition, a number of statistical methods like power calculations and required sample size calculations can be performed more easily on a pocket calculator, than using a software program. Also, there are some specific advantages of the pocket calculator method. You better understand what you are doing. The pocket calculator works faster, because far less steps have to be taken, averages can be used. The current nonmathematical book is complementary to the nonmathematical "SPSS for Starters and 2nd Levelers" (Springer Heidelberg Germany 2015, from the same authors), and can very well be used as its daily companion.
The original stimulus which started KENNETH SPENCER on a study of the Agro myzid flies was an invitation, which he accepted, to translate from the German the monograph on Leaf Miners by Professor E. M. HERING. From this developed nearly 20 years of collaboration until Professor HERING's death in 1967. Dr. SPENCER has himself described over 600 new species in the family, many of which he collected and reared from known host plants during his extensive travels to all the five main continents. Largely as a result of his work, the number of species known in Britain has increased from 90 in 1945 to 313 today. He is thus uniquely qualified to write this book about the hundred and fifty or so species which are regularly associated with cultivated plants. Much of the taxonomic detail provided here will be of value primarily to specialists; but with the help of a microscope and the botanical host list (Chapter 2) and the numerous illustrations (mostly prepared by ANN SPENCER) those in agri cultural institutes and elsewhere should now be able to identify the majority of species found attacking crops in any part of the world." |
