This book was released on 1999 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae) is a worldwide pest of onions and other crops. In New York it is an annual threat to the commercial onion industry where populations are managed with regular applications of insecticides. Two peaks of flight activity occurred during the period when T. tabaci infest onions in New York. These flights were composed of both female and males of this species, as well as a smaller number of other species. On-plant populations consisted of both female and male T. tabaci but no other species of thrips. Numbers of thrips on onion plants increased steadily through the growing season, exceeding the economic threshold of three thrips per leaf by mid to late summer in most fields. During the period of population increase, and especially during peaks of flight activity, airborne thrips were captured in equal numbers on traps placed throughout onion fields. Peaks of flight activity and proportions of T. tabaci of all thrips captured in onions did not correspond with peaks, harvest or ratio of thrips captured in neighboring field and forage crops, although T. tabaci was found to be a dominant species in areas outside onion fields. Sexually reproducing strains of T. tabaci were collected from onion fields. These were found to be highly resistant to pyrethroids, including l -cyhalothrin. By contrast, T. tabaci collected in areas adjacent to onions, such as alfalfa fields, reproduced asexually and had low resistance to l -cyhalothrin. It was concluded that neighboring field and forage crops are not the most significant source of T. tabaci that invade onion fields each year and become hard to manage in New York. High levels of insecticide resistance indicate that a resistance management plan and the promotion of integrated pest management in New York's onion industry should be high priorities in the near future.

Book Synopsis Onions and Other Vegetable Alliums by : James L. Brewster
Download or read book Onions and Other Vegetable Alliums written by James L. Brewster and published by CABI. This book was released on 2008 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fully revised, expanded and updated edition of the successful text, Onions and Other Vegetable Alliums, relates the production and utilization of these familiar and important vegetable crops to the many aspects of plant science underpinning their production and storage technologies. Chapters cover species and crop types, plant structure, genetics and breeding, physiology of growth and development as well as pests and diseases, production agronomy, storage after harvest and the biochemistry of flavour, storage carbohydrates and colour and how this relates to nutritional and health benefits. From this wide perspective it is possible to see many examples where underlying scientific knowledge illuminates, explains and can improve agronomic practice. The reader will get an insight into how molecular methods are revolutionizing the study of taxonomy, genetics, pathology and physiology and how these methods are being applied in the breeding of improved crops.

Book Synopsis Integrated Pest Management by : A. J. Burn
Download or read book Integrated Pest Management written by A. J. Burn and published by . This book was released on 1987 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE: The idea of Integrated Pest Management (IPM) is not a new one, and since the term was first coined, it has come to achieve a range of different meanings. In its simplest form it is accepted as being a control strategy in which a variety of biological, chemical and cultural control measures are combined to give stable long term pest control. In its recent renaissance, IPM has more often been taken to describe more biologically oriented pest control strategies that have arisen following problems with purely chemical control. It is the purpose of the first six chapters of this book to consider fundamental principles for IPM development, and to outline current research progress and future research needs, in the light of technological developments and agricultural requirements. The final seven chapters of the book deal with the practical aspects of IPM implementation. The range of crop types considered represent the diversity of crop production and storage systems in Western Europe, with different ecological backgrounds, against which IPM might operate, and within which IPM has developed to differing extents.

Download or read book Integrated Pest Management written by Dharam P Abrol and published by Academic Press. This book was released on 2013-08-28 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated Pest Management: Current Concepts and Ecological Perspective presents an overview of alternative measures to traditional pest management practices using biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals, caused by concerns over environmental health and public safety, has resulted in the development of alternative, reduced risk crop protection products. These products, less toxic to the environment and easily integrated into biological control systems, target specific life stages or pest species. Predation — recognized as a suitable, long-term strategy — effectively suppresses pests in biotechnological control systems. Integrated Pest Management covers these topics and more. It explores the current ecological approaches in alternative solutions, such as biological control agents, parasites and predators, pathogenic microorganisms, pheromones and natural products as well as ecological approaches for managing invasive pests, rats, suppression of weeds, safety of pollinators, role of taxonomy and remote sensing in IPM and future projections of IPM. This book is a useful resource to entomologists, agronomists, horticulturists, and environmental scientists. Fills a gap in the literature by providing critical analysis of different management strategies that have a bearing on agriculture, sustainability and environmental protection Synthesizes research and practice on integrated pest management Emphasizes an overview of management strategies, with critical evaluation of each in the larger context of ecologically based pest management
