Available in PDF, EPUB and Kindle. Book excerpt: Most basic information on plant-mealybug interactions during the last decade has come from research on the cassava Manihot esculenta Crantz (Euphorbiaceae) system with two mealybug species, namely Phenacoccus manihoti Matile-Ferrero and Phenacoccus herreni Cox and Williams (Sternorrhyncha: Pseudococcidae). Both these insects cause severe damage to cassava in Africa and South America, respectively. This book reviews these interactions (plant selection by the insects, nutritional requirements

Download or read book Biorational Control of Arthropod Pests written by Isaac Ishaaya and published by Springer Science & Business Media. This book was released on 2009-08-28 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nearly 50 years, pest control was mostly based on broad-spectrum conv- tional insecticides such as organochlorines, organophosphates, carbamates and pyrethroids. However, the severe adverse effects of pesticides on the environment, problems of resistance reaching crisis proportions and public protests led to stricter regulations and legislation aimed at reducing their use. Ways to reduce the use of synthetic pesticides in plant protection and to use more alternative and novel me- ods for pest control or biorational control are the challenges of pest control for the twenty-first century. The term biorational (biological + rational) pesticides can be defined as the use of specific and selective chemicals, often with a unique modes of action, that are compatible with natural enemies and the environment, with minimal effect on n- target organisms. Biorational control is based on a diversity of chemical, biological and physical approaches for controlling insect pests which results in minimum risk to man and the environment.

Download or read book Grapevine Viruses Molecular Biology Diagnostics and Management written by Baozhong Meng and published by Springer. This book was released on 2017-07-05 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: The domestication of grapes dates back five thousand years ago and has spread to nearly all continents. In recent years, grape acreage has increased dramatically in new regions, including the United States of America, Chile, Asia (China and India), and Turkey. A major limiting factor to the sustained production of premium grapes and wines is infections by viruses. The advent of powerful molecular and metagenomics technologies, such as molecular cloning and next generation sequencing, allowed the discovery of new viruses from grapes. To date, grapevine is susceptible to 64 viruses that belong to highly diverse taxonomic groups. The most damaging diseases include: (1) infectious degeneration; (2) leafroll disease complex; and (3) rugose wood complex. Recently, two new disease syndromes have been recognized: Syrah decline and red blotch. Losses due to fanleaf degeneration are estimated at $1 billion annually in France alone. Other diseases including leafroll, rugose wood, Syrah de cline and red blotch can result in total crop loss several years post-infection. This situation is further exacerbated by mixed infections with multiple viruses and other biotic as well as adverse abiotic environmental conditions, such as drought and winter damage, causing even greater destruction. The book builds upon the last handbook (written over twenty years ago) on the part of diagnostics and extensively expands its scope by inclusion of molecular biology aspects of select viruses that are widespread and economically most important. This includes most current information on the biology, transmission, genome replication, transcription, subcellular localization, as well as virus-host interactions. It also touches on several novel areas of scientific inquiry. It also contains suggested directions for future research in the field of grapevine virology.

Download or read book Integrative Biological Control written by Yulin Gao and published by Springer Nature. This book was released on 2020-08-18 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first to integrate biological control into a conceptual framework – ecostacking - uniting all aspects of biological control and ecosystem services. In 2018 the "First International Congress of Biological Control" was organised and held in Beijing, China. The chapters highlight some of the achievements presented at the congress, worldwide. Of particular significance are the numerous contributions by Chinese researchers illustrating the remarkable progress made on developing and adopting multiple biological control strategies over vast agricultural areas, largely replacing chemical pesticides for sustainable agricultural and horticultural production. In many parts of the world including Europe, fragmented research based on short-term funding has been unable to answer to the needs to develop sustainable long-term solutions to crop protection, while colleagues in China have been successful in implementing programs that exemplify the power of the ecostacking approach. Key contributions by European and US specialists combined with the expertise and experiences by the Chinese contributors comprise the building blocks for the integration of biological control approaches into the overall frame of ecostacking. This book will lead the way to a broader, integrated adoption of biological control techniques in sustainable pest, disease and weed management supporting also the functioning of other key ecosystem services.

Download or read book Integrating Biological Control into Conservation Practice written by Roy van Driesche and published by John Wiley & Sons. This book was released on 2016-05-17 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species have a critical and growing effect upon natural areas. They can modify, degrade, or destroy wildland ecosystem structure and function, and reduce native biodiversity. Landscape-level solutions are needed to address these problems. Conservation biologists seek to limit such damage and restore ecosystems using a variety of approaches. One such approach is biological control: the deliberate importation and establishment of specialized natural enemies, which can address invasive species problems and which should be considered as a possible component of restoration. Biological control can be an effective tool against many invasive insects and plants but it has rarely been successfully employed against other groups. Safety is of paramount concern and requires that the natural enemies used be specialized and that targeted pests be drivers of ecological degradation. While modern approaches allow species to be selected with a high level of security, some risks do remain. However, as in all species introductions, these should be viewed in the context of the risk of failing to reduce the impact of the invasive species. This unique book identifies the balance among these factors to show how biological control can be integrated into ecosystem restoration as practiced by conservation biologists. Jointly developed by conservation biologists and biological control scientists, it contains chapters on matching tools to management goals; tools in action; measuring and evaluating ecological outcomes of biological control introductions; managing conflict over biological control; and includes case studies as well as an ethical framework for integrating biological control and conservation practice. Integrating Biological Control into Conservation Practice is suitable for graduate courses in invasive species management and biological control, as well as for research scientists in government and non-profit conservation organizations.

Download or read book Area wide Integrated Pest Management written by Jorge Hendrichs and published by CRC Press. This book was released on 2021-02-01 with total page 1028 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including non-target species, air, water and soil. The extensive reliance on insecticide use reduces biodiversity, contributes to pollinator decline, destroys habitat, and threatens endangered species. This book offers a more effective application of the Integrated Pest Management (IPM) approach, on an area-wide (AW) or population-wide (AW-IPM) basis, which aims at the management of the total population of a pest, involving a coordinated effort over often larger areas. For major livestock pests, vectors of human diseases and pests of high-value crops with low pest tolerance, there are compelling economic reasons for participating in AW-IPM. This new textbook attempts to address various fundamental components of AW-IPM, e.g. the importance of relevant problem-solving research, the need for planning and essential baseline data collection, the significance of integrating adequate tools for appropriate control strategies, and the value of pilot trials, etc. With chapters authored by 184 experts from more than 31 countries, the book includes many technical advances in the areas of genetics, molecular biology, microbiology, resistance management, and social sciences that facilitate the planning and implementing of area-wide strategies. The book is essential reading for the academic and applied research community as well as national and regional government plant and human/animal health authorities with responsibility for protecting plant and human/animal health.
