Available in PDF, EPUB and Kindle. Book excerpt: When first developed, chlorinated pesticides such as DDT, dieldrin, and mirex were received with open arms, quickly becoming popular as effective, economic agents against pests. But evidence began to mount that residues of these chemicals remained in the environment, not breaking down, often appearing in plants and animals. By the late seventies many pesticides had achieved a terrible notoriety and were subsequently banned in a number of countries. Of tremendous concern, then, is the persistence of pesticides in the environment. The major thrust of research and development in the area of pesticides has properly been the creation of substances that are both effective and degradable. Yet in order to successfully promote the use of biodegradable pesticides, one must fully understand the mechanism of degradation, and it is to this vital subject that we address ourselves in the present volume. According to the Biodegradation Task Force, Safety of Chemicals Com mittee, Brussels (1978), biodegradation may be defined as the molecular degradation of an organic substance resulting from the complex action of living organisms. A substance is said to be biodegraded to an environmentally acceptable extent when environmentally undesirable properties are lost. Loss of some characteristic function or property of substance by biodegradation may be referred to as biological transformation.
Download or read book Termites and Sustainable Management written by Md. Aslam Khan and published by Springer. This book was released on 2017-12-01 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: This termite Volume 2 comprises 13 chapters in an attempt to bring all available information on sustainable and eco-friendly termite management. The previous Volume considered the biology, social behaviour and economic importance of these insects. Chapters in this book dealing with damage and specific management of fungus-growing termites provide a review on most recent methodologies used for management. Termite damage crops from sowing till harvest. As it is difficult to detect damages in field, usually it is too late when the symptoms are noticed. A separate chapter on issues related to Indian agriculture and the contemporary practices being followed by majority of the Indian farmers is quite informative. Similarly, a case study for termites infesting Malaysian forests constitutes an important contribution. Various issues related to integrated and eco-friendly termite management in tropical conditions have been addressed comprehensively. Potential role of microbes has also been discussed in detail in other chapters. The information contained under these chapters should help termite management in a way that natural resources can be used and maintained for the generations to come. Similarly, the chapter on physical barriers contributes a wealth of information that can be useful all over the world where termite is a problem. Emphasis has been laid on reviewing contribution of synthetic chemical insecticides in termite management. A separate chapter dealing with standard norms in wood protection constitute a significant step in this direction. A further chapter throws light on the potential of biotechnology as a tool in management..
Download or read book Pine Wilt Disease A Worldwide Threat to Forest Ecosystems written by Manuel M. Mota and published by Springer Science & Business Media. This book was released on 2008-08-28 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pine wilt disease (PWD) is unquestionably a major threat to forest ecosystems worldwide. After seriously affecting Eastern Asian countries, the challenge is now in Europe, following its detection in Portugal in 1999 and its subsequent spread. For foresters, these were really very bad news and, in order for adequate action to be taken, scientists had to teach politicians about the seriousness of the problem. That is never an easy task, but it was successfully done at that time, mainly by the continued effort of Professor Manuel Mota. The challenge of having political decisions based on good science is fundamental for the success of any program, but especially in dif?cult situations such as those arising by the introduction of harmful organisms in new ecosystems. The success of the dialogue between science and policy requires intelligent partners from each side, which is not always necessarily the case... Examples of lack of recognition of problems raised by science are unfortunately abundant throughout the history of science. The recent recognition of the efforts of the Intergovernmental Panel on Climate Change (IPCC) and Al Gore with the - bel Prize, and the continued failure in taking appropriate actions by major political players is a dramatic modern example of the dif?culty of this dialogue...

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Pesticide Science: Abstracts and Addendum documents the proceedings of the Fourth International Congress of Pesticide Chemistry held in Zurich on July 24-28, 1978. This book discusses the synthesis of isocoumarins and their biological activities; structure-activity correlations in control of membrane-bound linolenic acid with substituted pyridazinones; and oxidative processes in pesticide transformation. The cardiovascular and neurotoxicity of endosulfan; chemistry and plant growth regulating activity of fusicoccin derivatives and analogs; and pesticide interactions with naturally occurring food components are also elaborated. This compilation likewise covers the techniques for deriving realistic estimates of pesticide intakes; confirmation tests for pesticides based on gas chromatographic techniques; surfactants in flowable formulations; and thin-layer densitometry. This publication is a good reference for biologists and chemists researching on pesticides and its relation to food and the environment.
Download or read book Chemistry of Pesticides written by N. N. Melnikov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was originally published as a Russian edition in mid-1968. It represented the first single-volume discussion of chemical pest control and of the detailed chemistry.of all modern pesticide chemicals since D. E. H. Frear's classical book on this same subject, first published in 1942 (van No strand) with the latest (third) edition in 1955. Since 1955 many new pesti cide chemicals have achieved commercial status, and many of the older ones have been supplanted. There is no up-to-date equivalent of this present volume in the world literature, with the exception of the encyclopedic and largely biologically oriented two-volume work "Chemie der Pflanzenschutz und Schadlingsbekampfungsmittel" (R. Wegler, ed.) published by Springer Verlag in 1970. Professor Melnikov has updated the 1968 Russian edition, with emphasis on the primary Russian sources yet with excellent world wide coverage of the latest chemicals to approach field stature in modern chemical pest control, for the present translation."
Download or read book Termites and Sustainable Management written by Md. Aslam Khan and published by Springer. This book was released on 2018-02-19 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Volume comprises 12 chapters in an attempt to bring available information on biology, social behavour and economic importance of termites. Chapters in this book dealing with termites identification provide a review on most updated information of their systematics. Ecologically, termites interact with living and non-living surroundings and deliver a wide range of behaviors. In a separate chapter termites ecology is examined and explored. Termites depend on their gut microbes for digestion of complex polysaccharides of wood into simpler molecules. Information provided on termite gut microbiome and lignocellulose degradation constitutes an important contribution. Termite biology and social behaviour have been addressed comprehensively. Trail pheromones are responsible for the orientation and recruitment of nestmates to the food sources. Once arriving at a potential food source, termites assess its quality using a different set of cues. A separate chapter on trail pheromones, cues used during foraging and food assessment, with preferences for foraging sites, contributes a wealth of information. Emphasis has been given on reviewing ecological benefits of termites in other chapters. The information with respect to termite species as an edible insect and the overall role it plays in food and nutrition security in Africa is quite informative. A separate chapter dealing with importance of termites and termitaria in mineral exploration constitutes a significant step in addressing the economic importance of this insect group.
