Download or read book Biology of Coccinellidae written by Ivo Hodek and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first monograph of Coccinellidae. Although the group finds inclusion both in Clausen's (1940) "Entomophagous Insects" and in Balduf's (1935) "Entomophagous Coleoptera", reference in these works is limited to three and twenty pages respectively. Moreover, the last thirty years since these books appeared have ~een a great deal of work on the group. The use of insecticides largely destroyed the early attempts at biological control and interest remained low for as long as insecticides appeared quite successfuL However, the problems of insecticides soon became apparent, and in the last decade there have been tremendous developments in biological control, particularly in eombin

Download or read book Water Balance in Land Arthropods written by E. B. Edney and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Writers on arthropod water relationships range from bio physicists and biochemists to population ecologists-a fact that gives cause to wonder whether the field is already too heterogeneous to be written about in a single book by a single author. I have partly avoided the problem by concentrating largely on physiological mechanisms and by omitting most aspects of behavioural regulation and most aspects of heat balance and body temperature, except when these impinge directly on water balance. Even within this limited field there has been a lot of work during the past twenty years, as a result of which some problems have been solved (or at least more clearly defined), and many others have been opened up. On the whole there has been a welcome change to a more rigorous experimental approach and it is now possible for water balance people to state their problems in physiological terms. Good progress has been made towards understanding the mechanisms involved in nearly all avenues of water uptake and loss, although problems indeed remain. The cuticle has yielded part of its secrets to electron micrography, but ex ploration by means oflipid biochemistry among other techniques is necessary for a real understanding of cuticle permeability.

This book was released on 2012-05-21 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.
