Download or read book Insecticides with Novel Modes of Action written by Isaac Ishaaya and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future of insect control looked very bright in the 1950s and 1960s with new insecticides constantly coming onto the market. Today, however, whole classes of pesticide chemistry have fallen by the wayside due to misuse which generated resistance problems reaching crisis proportions, severe adverse effects on the environment, and public outcry that has led to increasingly stricter regulation and legislation. It is with this background, demanding the need for safer, environmentally friendly pesticides and new strategies to reduce resistance problems, that this book was written. The authors of the various chapters have a wealth of experience in pesticide chemistry, biochemical modes of action, mechanism of resistance and application, and have presented concise reviews. Each is actively involved in thedevelopment of new groups of pesticide chemistry which led to the development of novel insecticides with special impact in controlling agricultural pests. Emphasis has been given to insecticides with selective properties, such as insect growth regulators hormone mimics, ecdysone agonists), (chitin synthesis inhibitors, juvenile chloronicotinyl insecticides (imidacloprid, acetamiprid), botanical insecticides (neem, plant oils), pymetrozine, diafenthiuron, pyrrole insecticides, and others. The importance of these compounds, as components in integrated pest management programs and in insecticide resistance management strategies, is discussed. The data presented are essential in establishing new technologies and developing novel groups of compounds which will have impact on our future agricultural practices.
Download or read book Climate Change and Crop Stress written by Arun K.Shanker and published by Academic Press. This book was released on 2021-11-19 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate Change and Crop Stress: Molecules to Ecosystems expounds on the transitional period where science has progressed to ‘post-genomics’ and the gene editing era, putting field performance of crops to the forefront and challenging the production of practical applicability vs. theoretical possibility. Researchers have concentrated efforts on the effects of environmental stress conditions such as drought, heat, salinity, cold, or pathogen infection which can have a devastating impact on plant growth and yield. Designed to deliver information to combat stress both in isolation and through simultaneous crop stresses, this edited compilation provides a comprehensive view on the challenges and impacts of simultaneous stresses. Presents a multidisciplinary view of crop stresses, empowering readers to quickly align their individual experience and perspective with the broader context Combines the mechanistic aspects of stresses with the strategic aspects Presents both abiotic and biotic stresses in a single volume
Download or read book Global Forest Resources Assessment 2005 written by Food and Agriculture Organization of the United Nations and published by Fao. This book was released on 2006 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1946, FAO regularly monitors the world's forests through Global Forest Resources Assessments. The mandate to carry out these assessments stems both from the basic statutes of FAO and the Committee on Forestry (COFO). Divided into nine chapters, the publication covers the following topics: the extent of forest resources; biological diversity; forest health and vitality; productive functions of forest resources; protective functions of forest resources; socio-economic functions; progress towards sustainable forest management.

Download or read book Chitin and Benzoylphenyl Ureas written by James E. Wright and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: The opportunity to explore a developing new technology in a single biological system, chitin, from the molecular basis and with the inter relationship of the utilization of benzoylphenyl ureas in effective pest agroecosystem management strategies, represents a new evolution for integration of knowledge in this highly complex area. The degree of great progress and interest in the understanding of the interaction of chitin uItrastructures, biochemistry, and the unique ben zoylphenyl ureas attest to the timeliness of this effort. The purpose of the book that follows is to provide up-to-date and well illustrated details of current research knowledge including the latest of research results. The combination of the basic to the applied aspects rarely occurs specifically at the levels presented by the international contributors within. The original contributions composed the symposium "Chitin and Ben zoylphenyl Urea" organized by the co-editors at the International Con gress of Entomology in Hamberg, Germany, August 1984. We extend our appreciation to everyone who made the conference an outstanding success and highlight of the Congress, as well as making this book possible. We thank the authors, especially for their excellent international presenta tions, discussions, and preparation of the manuscripts. The knowledge evolved from many areas in chitin research, as well as the intricate com plexity of successful utilization of specific knowledge involving benzoylp henyl ureas in system management strategies for insects will continue to be in the forefront throughout the world's agroecosystems; and hopefully this book will enhance further research and development.
Download or read book Proceedings of the 10th International Symposium on Insect Plant Relationships written by Stephen J. Simpson and published by Springer Science & Business Media. 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.
Download or read book Insect Hormones and Bioanalogues written by K. Slama and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of organic insecticides in the agrotechnical praxis resulted in a great and unexpected progress in the control of insect pests, and was of a great economical value all over the world. The widespread application of these agents, however, is also accompanied by negative effects. The principal drawback of classical insecticides consists in the lack of their specificity, the useful insects being killed together with insect pests. Furthermore, the broad-scale application for many years led to the formation of more resistant insect strains requiring higher and higher doses of insecticides. The residues of the mostly used chlorinated compounds accumulate in human and animal foods producing directly or indirectly harmful effects in human sub jects. The critical situation led in many developed countries to the restriction in the usage of some types of classical insecticides. Under these circumstances it is quite natural that novel routes for the control of insect pests are investigated. In this connection, attention has been paid especially to the insect endocrinology and insect hormones which regulate the admirable and in many regards specific development from the egg to the adult insect. The recent successful discoveries in this field are thus in close relation to the practical requirements. Isolation and identification of moulting hor mones and juvenile-hormone-like naturally occurring substances not only made possible an exact investigation of their physiological effects but also stimulated the chemical research.
