This book was released on 2013-03-09 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original stimulus which started KENNETH SPENCER on a study of the Agro myzid flies was an invitation, which he accepted, to translate from the German the monograph on Leaf Miners by Professor E. M. HERING. From this developed nearly 20 years of collaboration until Professor HERING's death in 1967. Dr. SPENCER has himself described over 600 new species in the family, many of which he collected and reared from known host plants during his extensive travels to all the five main continents. Largely as a result of his work, the number of species known in Britain has increased from 90 in 1945 to 313 today. He is thus uniquely qualified to write this book about the hundred and fifty or so species which are regularly associated with cultivated plants. Much of the taxonomic detail provided here will be of value primarily to specialists; but with the help of a microscope and the botanical host list (Chapter 2) and the numerous illustrations (mostly prepared by ANN SPENCER) those in agri cultural institutes and elsewhere should now be able to identify the majority of species found attacking crops in any part of the world.

Available in PDF, EPUB and Kindle. Book excerpt: Field Crop Arthropod Pests of Economic Importance presents detailed descriptions of the biology and ecology of important arthropod pest of selected global field crops. Standard management options for insect pest control on crops include biological, non-chemical, and chemical approaches. However, because agricultural crops face a wide range of insect pests throughout the year, it can prove difficult to find a simple solution to insect pest control in many, if not most, cropping systems. A whole-farm or integrated pest management approach combines cultural, natural, and chemical controls to maintain insect pest populations below levels that cause economic damage to the crop. This practice requires accurate species identification and thorough knowledge of the biology and ecology of the target organism. Integration and effective use of various control components is often enhanced when the target organism is correctly identified, and its biology and ecology are known. This book provides a key resource toward that identification and understanding. Students and professionals in agronomy, insect detection and survey, and economic entomology will find the book a valuable learning aid and resource tool. - Includes insect synonyms, common names, and geographic distribution - Provides information on natural enemies - Is thoroughly referenced for future research

This book was released on 2019-03-21 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pest management for vegetable crops and safety provision for the pollinators is a challenging task in the context to increase vegetable productivity without upsetting the ecological balance. The book Pests and Pollinators of Vegetable and Oilseed Crops aims to integrate and develop pest control strategies by minimizing their impact on beneficial insect species such as natural enemies and pollinators for enhancing fruit production and quality. A detailed account is provided on pests and pollinators of oilseed crops such as Cruciferous, Solanaceous, Umbelliferous, Cucurbitaceous, Malvaceous, Leguminous and Alliaceae. The compilation of this book is unique as it does not deal only with the conventional way of pest management for different crops; it takes into consideration the role of pollinators and their profitable utilization in the larger context of ecologically based pest management and safety of pollinators. An exemplary attempt is made to promote a large, diverse, sustainable and dependable bee pollinator workforce that can meet the challenges of optimizing food production in the twenty-first century and beyond.
