Book The Ecology of Bruchids Attacking Legumes  Pulses

Download or read book The Ecology of Bruchids Attacking Legumes Pulses written by V. Labeyrie and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: As editor of this volume I am not going to emphasize the economic im portance of the Bruchids of pulses, nor how necessary it is to know the conditions of infestation of crops in order to achieve an efficient protection; both points are testified by F.A.O.'s sponsorship, as well as of the International Organization for Biological Control. On the other hand I would like to stress the scientific interest of the study of 'domestic' bruchids. It raises questions which require that present basic entomological knowledge be extended. I am not going to review all questions raised but I will emphasize those I am most aware of. Some bruchid species have been able to colonize habitats differing totally; some differing in their latitude, and thus their basic periodicities; others differing in their degree of complexity (stocks of seeds): What are the respective roles played by polymorphism and plasticity in that exceptional capacity? What differences are there between the populations living on wild plants in dispersal areas and those living in stocks? What are the alterations brought about by the drastic selection pressures in populations having later colonized habitats ecologically similar to the original habitats? What factors determine the degree of specificity of trophic relationships, and the possibilities of extension of the niche? What influences are exerted by the other elements of the original bio cenoses upon the behavioural evolution of these species? Such are a few fundamental problems that can be tackled directly through

This book was released on 2012-12-06 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1980, the International Symposium on the Ecology of Bruchids Attacking Legumes (Pulses), organized by Dr. Labeyrie, was held at Tours, France. Since then, there has been tremendous progress in the area of Bruchid and Legume research. At the same time, as we face the problems of world-wide population explosion and food shortage, the importance of legumes as the world's major protein source is rapidly increasing, especial ly in tropical regions. Thus, it seemed appropriate to hold the Second Symposium in order to review the recent progress in the control of Bruchids and in the biology and ecology of Bruchids and legumes. This is an important part of the search for ways to integrate these fields with a common perspective. The Second International Symposium on Bruchids and Legumes (ISBL-II) was held in September 6-9, 1989 at Okayama, Japan under the joint auspices of the Japanese Society of Applied Entomology and Zoology and of the Foundation for Advancement of International Science. Significant contributions have originated in Japan on the study of Bruchid and legumes. Most notably, the study on population ecology by Professor S.

Book Biological Invasions in Europe and the Mediterranean Basin

Download or read book Biological Invasions in Europe and the Mediterranean Basin written by F. di Castri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the massive change in the area of distribution of many world biota across classical biogeographical realms, and of the drastic restructuring of the biotic components of numerous ecosystems, the Scientific Committee on Problems of the Environment (SCOPE) decided at its general Assembly in Ottawa, Canada, in 1982 to launch a project on the 'Ecology of Biological Invasions'. Several regional meetings were subsequently organized within the framework of SCOPE, in order to single out the peculiarities of the invasions that took place in each region, the behaviour of their invasive species and the invasibility of their ecosystems. Most noteworthy among such workshops were one in Australia in August 1984, one concerning North America and Hawaii in October 1984, and one dealing with southern Africa in November 1985. A leitmotiv of these workshops was that most of the invasive species to those regions were emanating from Europe and the Mediterranean Basin, inadvertently or intentionally introduced by man. It was therefore considered as a timely endeavour to organize the next regional meeting in relation to this region. The workshop on 'Biological Invasions in Europe and the Mediterranean Basin' was held in Montpellier, France, 21 to 23 May 1986, thanks to the financial support of SCOPE and of the A.W. Mellon Foundation, and the logistic facilities of the Centre National de la Recherche Scientifique (C.N .R.S.).

Book Insect Bioecology and Nutrition for Integrated Pest Management

Download or read book Insect Bioecology and Nutrition for Integrated Pest Management written by Antônio Ricardo Panizzi and published by CRC Press. This book was released on 2012-03-08 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of insect nutritional ecology has been defined by how insects deal with nutritional and non-nutritional compounds, and how these compounds influence their biology in evolutionary time. In contrast, Insect Bioecology and Nutrition for Integrated Pest Management presents these entomological concepts within the framework of integrated pest management (IPM). It specifically addresses bioecology and insect nutrition in modern agriculture. Written for graduate students and professionals in entomology, this book covers neotropical information in three sections: General Aspects: Basic bioecology and insect nutrition; artificial diets; insect/plant interactions; insect symbionts; the interface of chemical ecology with the food; and insect cannibalism Specific Aspects: Specific feeding guilds of insects including ants, social bees, leaf chewers, seed suckers, seed chewers, root feeders, gall makers, detritivorous feeders, pests of storage grains, fruit flies, aphids, endo- and ectoparasitoids, predators, crisopids, and hematophagous insects Applied Aspects: Host plant resistance and the design of IPM programs in the context of insect bioecology and nutrition Much of the research on which these chapters were written was done in Brazil and based on its neotropical fauna. The complexity and diversity of the neotropics provides enough data that readers from all zoogeographical regions can readily translate the information in this book to their specific conditions. The book’s value as an entry point for further research is enhanced by the inclusion of approximately 4,000 references.

Download or read book Serengeti IV written by Anthony R. E. Sinclair and published by University of Chicago Press. This book was released on 2015-05-11 with total page 854 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast savannas and great migrations of the Serengeti conjure impressions of a harmonious and balanced ecosystem. But in reality, the history of the Serengeti is rife with battles between human and non-human nature. In the 1890s and several times since, the cattle virus rinderpest—at last vanquished in 2008—devastated both domesticated and wild ungulate populations, as well as the lives of humans and other animals who depended on them. In the 1920s, tourists armed with the world’s most expensive hunting gear filled the grasslands. And in recent years, violence in Tanzania has threatened one of the most successful long-term ecological research centers in history. Serengeti IV, the latest installment in a long-standing series on the region’s ecology and biodiversity, explores the role of our species as a source of both discord and balance in Serengeti ecosystem dynamics. Through chapters charting the complexities of infectious disease transmission across populations, agricultural expansion, and the many challenges of managing this ecosystem today, this book shows how the people and landscapes surrounding crucial protected areas like Serengeti National Park can and must contribute to Serengeti conservation. In order to succeed, conservation efforts must also focus on the welfare of indigenous peoples, allowing them both to sustain their agricultural practices and to benefit from the natural resources provided by protected areas—an undertaking that will require the strengthening of government and education systems and, as such, will present one of the greatest conservation challenges of the next century.

Book Proceedings of the 10th International Symposium on Insect Plant Relationships

This book was released on 2013-04-17 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 40 years, the SIP meetings have played a central role in the development of the field of insect-plant relationships, providing both a show-case for current research as well as a forum for the airing and development of influential new ideas. The 10th symposium, held 4-10 July 1998, in Oxford, followed that tradition. The present volume includes a representative selection of fully refereed papers from the meeting, plus a listing of the titles of all presentations. The volume includes reviews of major areas within the subject, along with detailed experimental studies. Topics covered include central neural and chemosensory bases of host plant recognition, integrative studies of insect behaviour, tritrophic interactions, plant defences, insect life histories, plant growth responses, microbial partners in insect-plant associations, and genetic bases of host plant associations. The book provides a key source for students and research workers in the field of insect-plant relationships.

The present volume includes a representative selection of fully refereed papers as well as a complete list of all the contributions which were presented at the meeting. Reviews of selected topics as well as original experimental data are included. The book provides valuable information for students and research workers interested in chemical and biological aspects of interactions between individuals and populations of different organisms.

Book Insect life cycle polymorphism

Download or read book Insect life cycle polymorphism written by H.V. Danks and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have shown that genetic polymorphisms play an important role in structuring the seasonal life cycles of insects, complementing an earlier emphasis on the effects of environmental factors. This book presents current ideas and recent research on insect life--cycle polymorphism in a series of carefully prepared chapters by international experts, covering the full breadth of the subject in order to give an up-to-date view of how life cycles are controlled and how they evolve. By consolidating our view of insect life--cycle polymorphism in this way, the book provides a staging point for further enquiries. The volume will be of interest to a wide variety of entomologists and other biologists interested in the control and evolution of life cycles and in understanding the extraordinarily complex ecological strategies of insects and other organisms.

Book Proceedings of the 9th International Symposium on Insect Plant Relationships

Download or read book Proceedings of the 9th International Symposium on Insect Plant Relationships written by Erich Städler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 9th International Symposium on Insect-Plant Relationships (SIP-9) was once more, following the tradition established in 1958, a forum for investigators in both basic and applied entomology interested in the important and fascinating field of interactions between plants and insects. We were pleased and honoured to organise this symposium, which took place June 24--30, 1995 in Gwatt on the shores of the Lake of Thun in Switzerland. 168 participants from 26 countries from all over the world actively took part in the symposium by contributing 12 key-note lectures and a total of 141 oral presentations and posters. The favourable response and the lively interaction of the participants in all symposium activities is the clearest indication of the success of SIP-9. The organisers appreciated the enthusiasm and the willingness to collaborate shown by all participants. The following volume contains written contributions (72) of only half of all presentations. This is due to the fact that we decided to produce not only an account of the proceedings but also to publish all contributions as a special volume of the journal Entomologia Experimentalis et Applicata. This procedure was last adopted in 1978 for SIP-4, organised by Reginald F. Chapman and Elizabeth A. Bernays, and ensures a wide distribution of the papers within the scientific community and easy access through libraries. Inevitably we had to employ the same review procedure as applicable for the manuscripts regularly submitted to Entomologia.

Download or read book Insects and Plants written by Pierre Jolivet and published by CRC Press. This book was released on 2023-07-07 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects and plants, whether or not they coevolved, have intimate interrelationships. This book concisely yet thoroughly describes these phenomena. In one chapter the salient facts known about carnivorous plants are described. In another, ant and plant relationships are summarized as an introduction to this vast subject. Pollination, of great interest to agriculturists and horticulturists, is briefly explained without the complexities detailed in the massive literature on this topic. Many other subjects are discussed, such as the memory of adult butterflies, which enables them to return to their host plants in the case of the polyphagous species. The book is seeded with such thought-provoking discussions as prostitution among the orchids and botanical indigestion in some plants.
