Download or read book Identification of variation within sex pheromone blends of various Maruca vitrata populations for refining pheromone lures and traps in Asia written by Stefanie Schläger and published by Cuvillier Verlag. This book was released on 2017-07-12 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The legume pod borer, Maruca vitrata, causes severe damage on legume crops in the tropics. The larvae are mainly controlled by synthetic insecticides but without satisfying results. Monitoring of the moths using pheromone traps can help to perform target-oriented control measures. The objective of this study was the improvement of pheromone traps for monitoring M. vitrata in tropical Asia, where synthetic pheromone lures failed to attract males so far. In addition, the sexual communication system of different M. vitrata populations was investigated, since variation in pheromone composition is a potential reason for failure of pheromone lures.

This book was released on 2021-10-06 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the widespread concept of integrated pest management, use of semiochemicals have been extensively studied to control agricultural pest insects. In this regard, aphrodisiac pheromones of two most destructive pest species of Pieris have been investigated. Individual pheromone constituents produced in the wings of two Asian populations were compared with two European populations of P. rapae. The total pheromone levels in the European populations were lower than the amounts present in wings of Asian populations. As a result of this study, we can conclude that both the subspecies of P. rapae showed a clear variation in pheromone profile between them. On the other hand, within subspecies, the different populations did not show very large differences. Therefore, the populations with geographical difference could not be considered identical as they showed significant quantitative differences in pheromone profiles. Furthermore, Electroantennographic analysis was also carried out to find out specific pheromone lures, which could be used for both the subspecies to carried out field bioassays in future, to test the mating disruption strategy.

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 Integrated Pest Management of Tropical Vegetable Crops written by Rangaswamy Muniappan and published by Springer. This book was released on 2016-11-23 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is an edited book with chapters written by multi-disciplinary specialists in their specific subject areas. It covers development of IPM components and packaging them for individual vegetable crops specifically targeted to tropical countries. Scientific background for IPM components or tactics will be included. There will be case studies of IPM packages developed and implemented in different countries. The concept of IPM has been in existence for the past six decades; however, a practical holistic program has not been developed and implemented for vegetable crops, in the developing countries. Currently the IPM adoption rate in the tropics is minimal and there is a need for implementation of IPM technologies that are environmentally safe, economical, and socially acceptable. We believe that adoption and implementation of IPM provided in this book will lead to significant reduction in crop losses and mitigate adverse impacts of pesticide use in the tropics. This book is an outcome 20 years of research, development and implementation of the IPM CRSP, a project supported by USAID and administered by Virginia Tech in several developing countries along the tropical belt in Africa, Asia, Latin America and the Caribbean.

Download or read book Crop Adaptation to Climate Change written by Shyam Singh Yadav and published by John Wiley & Sons. This book was released on 2011-07-26 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major task of our time is to ensure adequate food supplies for the world's current population (now nearing 7 billion) in a sustainable way while protecting the vital functions and biological diversity of the global environment. The task of providing for a growing population is likely to be even more difficult in view of actual and potential changes in climatic conditions due to global warming, and as the population continues to grow. Current projections suggest that the world's temperatures will rise 1.8-4.0 by 2100 and population may reach 8 billion by the year 2025 and some 9 billion by mid-century, after which it may stabilize. This book addresses these critical issues by presenting the science needed not only to understand climate change effects on crops but also to adapt current agricultural systems, particularly in regard to genetics, to the changing conditions. Crop Adaptation to Climate Change covers a spectrum of issues related to both crops and climatic conditions. The first two sections provide a foundation on the factors involved in climate stress, assessing current climate change by region and covering crop physiological responses to these changes. The third and final section contains chapters focused on specific crops and the current research to improve their genetic adaptation to climate change. Written by an international team of authors, Crop Adaptation to Climate Change is a timely look at the potentially serious consequences of climate change for our global food supply, and is an essential resource for academics, researchers and professionals in the fields of crop science, agronomy, plant physiology and molecular biology; crop consultants and breeders; as well as climate and food scientists.
Download or read book Fruit Fly Research and Development in Africa Towards a Sustainable Management Strategy to Improve Horticulture written by Sunday Ekesi and published by Springer. This book was released on 2018-04-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horticultural sector presents many opportunities for economic development and improving livelihood of growers but several factors constrain production and limit the potential for trade of fruits and vegetables. Tephritid fruit flies constitute a major constraint. They cause enormous losses through direct feeding damage and loss of market opportunities through imposition of quarantine restrictions by importing countries to prevent entry and their establishment. In Africa, several native (Ceratitis and Dacus spp) and exotic (Bactrocera and Zeugodacus spp.) species inflict considerable losses to horticulture causing losses ranging from 30-90%. Over the past 10 years of R&D, extensive information has been generated on bioecology and management of several native and exotic fruit flies in Africa. While several specific reviews have addressed various aspects of the biology, ecology and management of economically important tephritid fruit flies; coverage of African native species has been limited largely to Bactrocera oleae and Ceratitis capitata – which are not economically important species in many Africa countries. Indeed, no book exist that have explicitly addressed economically important African fruit flies and none of the various reviews, have specifically focused on the status of the bioecology, economic impact and management of exotic and native fruit flies – including several potentially invasive Dacus species attacking vegetables - in Africa. This book consolidates this status of knowledge and socio-economic impact of various intervention techniques that are currently being applied across Africa. The timing of the book is especially pertinent due to the changing fruit fly landscape in Africa – caused by arrivals of the highly destructive alien invasives (Bactrocera dorsalis, B. zonata, and B. latifrons) - and the priorities African countries have placed recently on export of fruits and vegetables to international markets. This is an important reference material for researchers, academics and students that are keen at improving horticulture and enhancing food and nutrition security in Africa and beyond.

Available in PDF, EPUB and Kindle. Book excerpt: A New York Times Notable Book for 2011 A Globe and Mail Best Books of the Year 2011 Title A Kirkus Reviews Best Nonfiction of 2011 title Virtually all human societies were once organized tribally, yet over time most developed new political institutions which included a central state that could keep the peace and uniform laws that applied to all citizens. Some went on to create governments that were accountable to their constituents. We take these institutions for granted, but they are absent or are unable to perform in many of today’s developing countries—with often disastrous consequences for the rest of the world. Francis Fukuyama, author of the bestselling The End of History and the Last Man and one of our most important political thinkers, provides a sweeping account of how today’s basic political institutions developed. The first of a major two-volume work, The Origins of Political Order begins with politics among our primate ancestors and follows the story through the emergence of tribal societies, the growth of the first modern state in China, the beginning of the rule of law in India and the Middle East, and the development of political accountability in Europe up until the eve of the French Revolution. Drawing on a vast body of knowledge—history, evolutionary biology, archaeology, and economics—Fukuyama has produced a brilliant, provocative work that offers fresh insights on the origins of democratic societies and raises essential questions about the nature of politics and its discontents.
