This book was released on 2013-03-14 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years the importance of adjuvants for optimising the activity of agrochemicals has become increasingly recognized. This book is aimed at accumulating the current knowledge of the interactions between adjuvants, agrochemicals and target organisms. It provides results, and ideas for future research and defines new methodological, biomechanistic and systematic approaches which can be implemented to streamline research and development of formulations and adjuvant/active ingredient combinations. The book contains micrographs of leaf surfaces and spray deposits, graphical and statistical presentations, and data on the properties of adjuvants. In particular a case study is presented demonstrating the interactions possible between formulation and adjuvant types.
Download or read book The Family Trichodoridae Stubby Root and Virus Vector Nematodes written by W. Decraemer and published by Springer Science & Business Media. This book was released on 2013-04-09 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The family Trichodoridae was established by Thorne in 1935 but it remained of limited taxonomie interest until 1951 when Christie and Perry associated Trichodorus christie (now Paratrichodorus minor) with a "stubby root disease" that affected certain crops in Florida, USA and interest further increased from 1960 when P. pachydermus was implicated as a vector of the economically important tobacco raule virus. Such discoveries gave an impetus to studies on many aspects of the biology of trichodorid nematodes with a consequent proliferation of new species described from different parts of the world. The number of species increased from twelve in 1957 to a present day total exceeding eighty. This rapid expansion in the number of species was accompanied by several reappraisals of the taxonomy and systematies of the family, the most notable changes being the creation of the genus Paratrichodorus by Siddiqi in 1974 and the recognition of the monodelphic genera Monotrichodorus and Allotrichodorus respectively by Andrassy in 1976 and Rodriguez-M, Sher and Siddiqi in 1978. Reliable and unambiguous identification of taxa is dependent on the known reliability of a range of characters, whieh remains of paramount importance in taxonomy even when biochemical and molecular methodology is available. In this book each of the species, including synonyms and species inquirenda, that comprise the family Trichodoridae is re-described from meticulous mieroscopie examination of type specimens, material from official nematode collections and populations in the field.

Download or read book Pheromone Communication in Moths written by Jeremy D. Allison and published by Univ of California Press. This book was released on 2016-10-25 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Common among moths is a mate-finding system in which females emit a pheromone that induces males to fly upwind along the pheromone plume. Since the chemical pheromone of the domesticated silk moth was identified in 1959, a steady increase in the number of moth species whose pheromone attractants have been identified now results in a rich base for review and synthesis. Pheromone Communication in Moths summarizes moth pheromone biology, covering the chemical structures used by the various lineages, signal production and perception, the genetic control of moth pheromone traits, interactions of pheromones with host-plant volatiles, pheromone dispersal and orientation, male pheromones and courtship, and the evolutionary forces that have likely shaped pheromone signals and their role in sexual selection. Also included are chapters on practical applications in the control and monitoring of pest species as well as case studies that address pheromone systems in a number of species and groups of closely allied species. Pheromone Communication in Moths is an invaluable resource for entomologists, chemical ecologists, pest-management scientists, and professionals who study pheromone communication and pest management.

Download or read book Mites of Greenhouses written by Zhi-Qiang Zhang and published by CABI. This book was released on 2003-01-01 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mites are among the most important arthropods in greenhouses, both as pests causing economic injury to greenhouse crops, and as natural enemies used in the biological control of pest insects and other mites. Because of their minute size, mites are much less well known than insects. This book describes the biology, identification and control of such mites and the topics covered include an introduction to the Acari, illustrated keys to orders, families and selected species, the control of pest mites, and the role of beneficial mites in biological control. The book will be of interest to those working in entomology, crop protection and horticulture.

Available in PDF, EPUB and Kindle. Book excerpt: Herbicide Resistance in Weeds and Crops is a collection of papers presented at the 11th Long Ashton International Symposium in September 1989. The said symposium is held to study about the increasing incidence of herbicide-resistant weeds and the consideration of the production of herbicide-resistant crops. The book includes studies that suggest the delay and prevention of herbicide resistance; the gravity of the infestation of different herbicide-resistant weed; the management of herbicide resistance; and the mechanisms of herbicide tolerance. Also covered in the book are the improvement of different herbicides, as well as the prospective development of genetically engineered herbicide-resistant plants. Botanists, biochemists, and farmers would greatly benefit from the text, especially those who would like to explore and study the phenomenon.
Download or read book Ecology and conservation of the Dutch ground beetle fauna written by Hans Turin and published by BRILL. This book was released on 2023-09-14 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades, large amounts of data about carabids have been collected in the Netherlands, initially for the purpose of creating distribution maps for the country. In addition to information from collections and faunistic publications, a significant amount of data came from ecological studies using pitfall traps. Because of the rich tradition of carabidological research in the Netherlands, an exceptionally large database of these pitfall data is available. The database is a mix of approximately 1,500 short-term samples and circa 4,400 so-called 'year-samples', for which pitfalls were functional during the whole activity period of ground beetles in spring and autumn. These year-samples came from 2,850 sites, covering the period of 1953-2018, and represent all habitats on the Dutch landscape. These data offer an unusual view of the presence and activity of this common insect family. The data gathered from pitfall trapping is summarised and provides a fresh integrated perspective about the Dutch ground beetle fauna. The characteristic species composition of 17 habitat groups is described in detail. Over 320 species present in the database have been classified into six main groups, according to their patterns of habitat use. Both the classification of habitats and associated species have been tested and used in various analyses in the book. Two chapters give special attention to changes in the Dutch fauna over the past 66 years by means of extensive trend analysis and relate this understanding to nature conservation. The book provides an extension and update for Turin's (2000) atlas. The Dutch carabid fauna is discussed considering relevant literature but uses predominantly European studies to put the faunal patterns in broader context. This book presents the story of Dutch ground beetles and illustrates the contribution of pitfall trapping to our understanding of the ecology of this fascinating and unusually well-studied group of beetles.

Download or read book Sustainable Pest Management in Date Palm Current Status and Emerging Challenges written by Waqas Wakil and published by Springer. This book was released on 2015-12-21 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Date palm, Phoenix dactylifera L. (Arecales: Arecaceae), is an important palm species cultivated in the arid regions of the world since pre-historic times and traditionally associated with the life and culture of the people in the Middle-East and North Africa which are the pre-dominant date palm growing regions worldwide. The Food and Agriculture Organization of the UN estimates that there are over 100 million date palms with an annual production of over 7.5 million tonnes A recent report on the arthropod fauna of date palm, enlists 112 species of insects and mites associated with date palm worldwide including 22 species attacking stored dates. Enhanced monoculture of date palm in several date palm growing countries coupled with climate change, unrestrained use of chemical insecticides and extensive international trade is likely to impact the pest complex and the related natural enemies in the date agro-ecosystems. In view of the importance of date palm as an emerging crop of the future and the need to develop and deploy ecologically sound and socially acceptable IPM techniques, this book aims to comprehensively address issues related to the biology and sustainable management of major insect and mite pests of date palm by assessing the current IPM strategies available, besides addressing emerging challenges and future research priorities. The issues pertaining to the role of semiochemicals in date palm IPM involving new strategies revolving around “attract and kill” and “push-pull” technologies, phytoplasmas and their insect vectors with implications for date palm, innovative methods for managing storage pests of dates and knowledge gaps in devicing sustainable strategies for the management of red palm weevil, Rhynchophorus ferrugineus (Olivier) are also addressed
