Drawing together information previously found only in articles, reviews, symposia proceedings, commercial literature, and medical entomology texts, Insect Repellents: Principles, Methods, and Uses is a one-volume source on the development, evaluation, and use of repellents. It provides a thoughtful analysis of old and new information, from the ancient history of people’s attempts to avoid bites, through the use of synthetic and botanical products, to pioneering techniques for development of repellent products. After reading this book, you will be able to perform the next step in research, thoroughly evaluate data on repellents, and choose the best products for any situation. The editors introduce and define the word “phagomone” to fill the gap created by the many different meanings attributed to the word “repellent.” They present the history of repellent production that has led to the formulations currently in use and discuss the biological variety of phagomones as they function in nature. The book then delineates the methods used to assess the activity of phagomones and repellent products. A special feature of the book is its coverage of what many consider the cutting-edge in repellent testing: automated tests of the arthropods’ responses, the use of computer models of chemistry, and the use of molecular biology methods. The book comprehensively compares active ingredients and includes an index of illustrated chemical structures that lists most chemicals involved in repellent development. A thought-provoking discussion of the process of testing formulated products and comprehensive reviews of natural and synthetic active ingredients round out the book’s coverage. It supplies an in-depth understanding of the variety of purposes served by repellent bioassays and lays the foundation for evaluating data and designing new tests as well as developing and delivering new tools and approaches. This book provides all the information you need to give evidence-based recommendations.

Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

The public has a great desire for products that prevent the annoyance of biting insects and ticks, but that desire does not always translate into sensible use of those products. Insect Repellents Handbook, Second Edition summarizes evidence-based information on insect repellents to inform decisions by those involved with insect repellent research, development, and use. This authoritative, single-source reference makes it possible for you to quickly gain a working level of expertise about insect repellents, without having to search through the scattered literature. The previous edition was the first comprehensive volume on this subject and quickly became the definitive reference on insect repellents. This second edition reflects the current state of insect repellent science, covers the processes involved in the development and testing of new active ingredients and formulations, and discusses the practical uses of repellents. The book includes thought-provoking discussions on how repellents work, their neuromolecular basis of action, and whether green chemistry can provide effective repellents. It also supplies an in-depth understanding of the development of repellents including testing methods, review of active ingredients, and the use of chemical mixtures as repellents. It provides science-backed chapters on repellent use including best practices for use of personal protection products, criteria for repellent use, and insect repellents for other potential use.

Despite their potentially adverse effects on nontarget species and the environment, insecticides remain a necessity in crop protection as well as in the reduction of insect-borne diseases. The Toxicology and Biochemistry of Insecticides provides essential insecticide knowledge required for the effective management of insect pests. Continuing as the sole book in more than two decades to address this multifaceted field, the Second Edition of this highly praised review on insecticide toxicology has been greatly expanded and updated to present the most current information on: Systemic classification of insecticides How insecticides function at the molecular level and newly discovered modes of action Insecticide resistance, molecular mechanisms, fitness costs, reversion, and management of resistance Various bioassay methods including the interpretation of probit analysis Molecular mechanisms of insecticide selectivity Major biochemical mechanisms involved in the transformation of insecticides Fate of insecticides in the environment and the sublethal effects of insecticides on wildlife Newly developed insecticides, including the addition of more microbial insecticides in keeping with current integrated pest management (IPM) approaches Incorporating extensive reference lists for further reading, The Toxicology and Biochemistry of Insecticides, Second Edition is an ideal textbook for students of entomology, plant medicine, insecticide toxicology, and related agricultural disciplines. It is also a valuable resource for those involved in insecticide research, environmental toxicology, and crop protection.

Es begann damit, dass Nicholson Baker, erfolgreicher Autor von Romanen wie «Vox» und «Die Fermate», in der Zeitschrift «The New Yorker» einen Artikel darüber veröffentlichte, dass die Computerisierung der Kataloge einem Bibliotheksbesuch viel von seinem Charme und seiner Effizienz genommen habe. Dann erfuhr er, dass der Neubau der San Francisco Public Library zu klein geraten war für den vorhandenen Bestand und dass die Verwaltung daraufhin ein paar hunderttausend Bände auf eine Müllkippe bringen ließ – das Raumproblem war gelöst. Schließlich entdeckte er, dass die großen renommierten amerikanischen und englischen Bibliotheken ihre wertvollen Sammlungen von Tageszeitungen nach der Mikroverfilmung auflösen. Da fing er an, ernsthaft zu recherchieren. Und fand heraus, dass es eine Lobby vom Fortschrittswahn irregeleiteter und von Raumnot bedrängter Bibliothekare gibt, - die in die Welt gesetzt hat, auf säurehaltigem Papier Gedrucktes werde «zu Staub verfallen», - die Mikroverfilmungen herstellt, die fehlerhaft, benutzerunfreundlich und hässlich sind, - die nun als «scan gang» Bücher digitalisiert, obwohl weder Hardware noch Programme eine problemlose Archivierung zulassen, - die alle Warnungen der auf Bewahrung des Vorhandenen bedachten Kollegen in den Wind schlägt ... «‹Der Eckenknick› informiert, argumentiert und verliert dabei nie die Kraft eines ironischen Manifests, das in Amerika zu erregten Diskussionen Anlass gegeben hat ... Es liest sich wie ein gut recherchierter Krimi und ein brillanter Essay zugleich ... Bibliothekare sind auch als Mörder leise. Um festzustellen, ob gestorben werden muss, genügt es ihnen oft, eine Ecke einer Buch- oder Zeitungsseite einmal vorn, einmal zurück zu falten. Wenn die Seite bricht, dann ist die Zeitung, das Buch in Lebensgefahr.» Süddeutsche Zeitung

Der stumme Frühling erschien erstmals 1962. Der Titel bezieht sich auf das eingangs erzählte Märchen von der blühenden Stadt, in der sich eine seltsame, schleichende Seuche ausbreitet … Das spannend geschriebene Sachbuch wirkte bei seinem Erscheinen wie ein Alarmsignal und avancierte rasch zur Bibel der damals entstehendenÖkologie-Bewegung. ZumerstenMal wurde hier in eindringlichem Appell die Fragwürdigkeit des chemischen Pflanzenschutzes dargelegt. An einer Fülle von Tatsachen machte Rachel Carson seine schädlichen Auswirkungen auf die Natur und die Menschen deutlich. Ihre Warnungen haben seither nichts von ihrer Aktualität verloren.
