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 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.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook series includes several naturally occurring chemicals that exhibit biological activity. These chemicals are derived from plants, insects, and several microorganisms. Volume I of this series is covers the theory and practice of the strategies for pest control and methods for detection.Moreover, it presents extensive tables that provide the information you need to select the most appropriate bioassay for a particular plant growth regulator or hormone. In addition to the chapters on bioassays, Volume I provides a solid introduction to the theory and practice of natural pesticide use, including in-depth discussions of integrated management systems for weed and pest control, the state-of-the-art use of computers in pest management, and allelochemicals as natural protection. Guidelines on toxicological testing and EPA regulation of natural pesticides are also detailed.

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 Protection Strategy against Spruce Budworm written by David A. MacLean and published by MDPI. This book was released on 2020-01-15 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spruce budworm (Choristoneura fumiferana (Clem.)) outbreaks are a dominant natural disturbance in the forests of Canada and northeastern USA. Widespread, severe defoliation by this native insect results in large-scale mortality and growth reductions of spruce (Picea sp.) and balsam fir (Abies balsamea (L.) Mill.) forests, and largely determines future age–class structure and productivity. The last major spruce budworm outbreak defoliated over 58 million hectares in the 1970s–1980s, and caused 32–43 million m3/year of timber volume losses from 1978 to 1987, in Canada. Management to deal with spruce budworm outbreaks has emphasized forest protection, spraying registered insecticides to prevent defoliation and keep trees alive. Other tactics can include salvage harvesting, altering harvest schedules to remove the most susceptible stands, or reducing future susceptibility by planting or thinning. Chemical insecticides are no longer used, and protection strategies use biological insecticides Bacillus thuringiensis (B.t.) or tebufenozide, a specific insect growth regulator. Over the last five years, a $30 million research project has tested another possible management tactic, termed an ‘early intervention strategy’, aimed at area-wide management of spruce budworm populations. This includes intensive monitoring to detect ‘hot spots’ of rising budworm populations before defoliation occurs, targeted insecticide treatment to prevent spread, and detailed research into target and non-target insect effects. The objective of this Special Issue is to compile the most recent research on protection strategies against spruce budworm. A series of papers will describe results and prospects for the use of an early intervention strategy in spruce budworm and other insect management.
