Download or read book Insect Photoperiodism written by Stanley D. Beck and published by Elsevier. This book was released on 2012-12-02 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect Photoperiodism reviews the many aspects of photoperiodism, particularly in insects, emphasizing the concepts that serve to place the subject in a meaningful relationship to the whole of modern biology. Photoperiodism is the study of the adaptive mechanisms by which living systems exploit this source of temporal information. Organized into 12 chapters, this book begins by discussing the relationships between an endogenous behavioral rhythm and the exogenous photoperiod. Aside from behavioral activities, it also shows that some observable developmental events tend to occur at species-typical times of the day and to be photoperiodically regulated. Notably, photoperiod may exert either or both of two regulatory effects on insect development: growth rate effects or polymorphism. Furthermore, the characteristics of some of the principal physiological rhythms that have been studied; role of photoperiod in the control of diapauses; and the circadian functions and theoretical nature of biological clock are explored in this book.
Download or read book Ecology of Coccinellidae written by Ivo Hodek and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coccinellids have been very actively studied in the course of the twenty three years since "Biology of Coccinellidae" was published. The great amount of new, and often very important findings have made the previous book outdated and a new synthesis is needed. No other monograph of similar focus and extent has appeared. Iablokoff Khnzorian's "Les Coccinelles" (1982), limited to the tribus Coccinellini, and Gor don's "The Coccinellidae of America North of Mexico" (1985) both concentrate on taxonomy. Majerus' beautiful "Ladybirds" (1994) deal specifically with British coc cinellids and address chiefly amateur naturalists. The focus and the title of the recent book are slightly different from the 1973 vol ume. If a satisfactory comprehensive review of important new findings is attempted, the book would grow too much, due also to References and Indexes. To keep the vol ume at a tolerable extent, the section on larval identification of Palaearctic species has been omitted; not much could be added to the previous version of that part, any way. However, we have kept Kovar's chapter on morphology and anatomy, because of its relation to feeding and other ecological aspects. The chapter on phylogeny was updated also by him. Our Polish friend, Piotr Ceryngier, who has recently specialised in parasites, updated perfectly the parts on parasites and pathogens in Chapter 8. We would be glad if their contribution is quoted by their names. It seems to us that the remarks, contained in the reprinted preface to the previous volume, remain pertinent today.
Download or read book Ecology and Behaviour of the Ladybird Beetles Coccinellidae written by Ivo Hodek and published by John Wiley & Sons. This book was released on 2012-04-19 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Zoological Catalogue of Australia written by G. Cassis and published by CSIRO PUBLISHING. This book was released on 2002 with total page 760 pages. Available in PDF, EPUB and Kindle. Book excerpt: The infraorder Pentatomomorpha is the subject of the second volume in the Zoological Catalogue of Australia series dealing with the true bugs (the suborder Heteroptera). It includes the bark bugs, stilt bugs, seed bugs, cotton stainers, burrowing bugs, shield bugs and stink bugs. Many of these species are of significant economic importance both as pests and as natural enemies of other insect pests. In this catalogue, the authors propose a new classification for the Australian Heteroptera based on the most recent developments in heteropterology worldwide. The proposed classification departs significantly from all previous treatment of the Australian fauna. There is a comprehensive treatment of the classification and nomenclature of the Australian species and a thorough review of the literature concerned with the higher classification of the Pentatomomorpha. The volume gives detailed information on the distribution and ecology of each species and features the first in depth listing of their host associations, including a significant accounting of the plant associations. All species and generic synonymies are given, including extra-limital synonyms, along with detailed type specimen data. Features * Provides a new classification for the Australian Heteroptera, reflecting the most recent developments in Heteropterology worldwide * Covers 34 families, 439 genera and 1179 species * Completes the work for the Australian Heteroptera, complementing volume 27.3A * Includes comprehensive synonymical and bibliographic listings and detailed distribution information * Gives the first listing of the host plants of the Pentatomomorpha in Australia * Sample
Download or read book The Mayflies of Europe Ephemeroptera written by Ernst Bauernfeind and published by BRILL. This book was released on 2013-01-21 with total page 779 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the various groups of aquatic insects, mayflies (Ephemeroptera) are of special interest for professional limnologists and entomological researchers as well as for naturalists in general and even the dedicated fly angler. Identification has traditionally been considered difficult and implementation in environmental monitoring and freshwater management has led to an ever increasing demand for exact information on taxonomy and ecology. The present handbook is designed to provide for the first time an up-to-date standard work for Ephemeroptera identification, including last instar larvae (nymphs), subimago (dun), male and female imagines. Recent changes in nomenclature are discussed in detail as well as gaps in current knowledge and probable pitfalls concerning the reliable identification of all taxa known so far from the region. Keys are provided for genera and introductory chapters characterize every family and genus. Species accounts follow a common format providing a synonymy, characters for identification (including literature references), remarks (on type material, variation, confusing or extralimital species) and short information on biology and distribution pattern. Male genitalia are illustrated by micrographs and line drawings, REM photographs of the egg chorionic structure are provided for genera and selected species. Habitus of larvae and imagines are for most genera illustrated by colour photographs. The geographical area covered is Europe including the European part of Russia, the mediterranean islands and North Africa. Short additional information is provided for adjacent parts of the western Palaearctic Region. A comprehensive index, check-list and distribution catalogue (following the widely adopted concept of Illies’ Limnofauna Europaean) allow for quick information on all species recorded so far from Europe.
Download or read book Recent Developments in Insect Neurohormones written by M. Raabe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most striking fact revealed by investigations of insect neurohormones is that insects are as well supplied with neurohormones as mammals, since neurohor mones regulate not only the functioning of the endocrine glands, prothoracic gland, and corpora allata, but also most physiological processes. Our knowledge of neurohormones developed originally from anat omocytological investigations and experimental studies. Today, accurate bio assays have been devised for studying both in vivo and in vitro physiological processes, and RIA determination has yielded knowledge of titer modifications of humoral factors. Much is also known about neurohormone purification, and several neurohormones have even been identified in different species. Immunocytochemistry has made it possible to demonstrate in their origin and release sites the presence of insect neurohormones whose structure has been elucidated. Moreover, the presence of vertebrate and invertebrate neuropeptides has been demonstrated in insects. As regards biogenic amines, methods of detection have been greatly refined and it is now possible to identify the cell bodies and axons of the main biogenic amines. Other new methods, such as cobalt chloride impregnation or Lucifer yellow staining, have revealed the axonal pathways and the location of particular neurons. The mechanisms of action of neurohormones have been investigated in several cases and the results of these investigations will be related in the chapters which follow.

Download or read book Nontarget Effects of Biological Control written by Peter A. Follett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nontarget Effects of Biological Control is the first book of its kind. The environmental safety of biological control has come under scrutiny due to several areas of concerns: the irreversibility of alien introductions, the prevalence of host switching to innocuous native or beneficial species, dispersal of the biocontrol agent to new habitats away from croplands, and the lack of research on the efficacy and impact of biocontrol attempts. The debate has been strongly polarized between conservationists and biological control practitioners. Nontarget Effects of Biological Control proposes that retrospective analyses of systems in place in which nontarget effects are now documented or suspected provide the necessary information for planning and evaluating future releases to reduce risk. The book presents case histories of past biological control introductions from island and continental ecosystems.
