Biology and Management of Bactrocera and Related Fruit Flies (Hardcover): Anthony R. Clarke Biology and Management of Bactrocera and Related Fruit Flies (Hardcover)
Anthony R. Clarke
R2,316 Discovery Miles 23 160 Ships in 12 - 17 working days

Throughout Asia, Australia and the Pacific, and increasingly in Africa, the primary horticultural insect pests are fruit flies belonging to the genera Bactrocera, Zeugodacus and Dacus (Diptera: Tephritidae: Dacini). The Dacini is a hugely diverse clade of nearly 900 species endemic to the rainforests of Asia, Australia and the western Pacific, and the savannas and woodlands of Africa. All these species lay their eggs into fleshy fruits and vegetables, where the maggots feed, therefore destroying the fruit. In addition to being crop pests, dacines are also invasive pests of major quarantine importance and their presence in production areas can significantly impact market access opportunities. This broad text provides a rapid introduction to this economically and ecologically important group, which includes species such as the Oriental fruit fly (B. dorsalis), Melon fly (Z. cucurbitae), Queensland fruit fly (B. tryoni) and the Olive fly (B. oleae). Broken into three primary sections, it first explores the evolutionary history, systematic relationships, taxonomy and species-level diagnosis of the Dacini flies. The following biology section covers their life history, population demography, behaviour and ecology, and natural enemies. The final section of the book covers the management of these flies, with chapters on pre-harvest, post-harvest and regulatory controls. Each chapter concludes with a list of key monographs, papers or book chapters for further reading. This book will be of interest to field entomologists, extension officers, quarantine officers and market access negotiators, as well as students of applied entomology and pest management.

The chemistry of heterocycles is an important branch of organic chemistry. This is due to the fact that a large number of natural products,
e. g. hormones, antibiotics, vitamins, etc. are composed of heterocyclic structures. Often, these compounds show beneficial properties and are
therefore applied as pharmaceuticals to treat diseases or as insecticides, herbicides or fungicides in crop protection. This volume presents important agrochemicals. Each of the 21 chapters covers in a concise manner one class of heterocycles, clearly structured as follows:
* Structural formulas of most important examples (market products)
*Short background of history or discovery
* Typical syntheses of important examples
* Mode of action
* Characteristic biological activity
* Structure-activity relationship
* Additional chemistry information (e.g. further transformations, alternative syntheses, metabolic pathways, etc.)
* References
A valuable one-stop reference source for researchers in academia and industry as well as for graduate students with career aspirations in the

Arthropods as pests in crops, vectors of diseases, pollinators, and natural enemies of pests are of huge economic importance. They affect livestock, human health and food supplies around the world. This unique book examines and reviews how light and colour can be used to enhance pest management in agricultural and medical applications by manipulating the optical responses of arthropods. Arthropods use optical cues to find food, oviposition sites and to navigate. Light also regulates their diurnal and seasonal activities. Plants use optical cues to attract or deter various species of arthropod. In this book, an international team of experts show how light can be used successfully to attract, arrest, confuse and deter arthropods as well as to disrupt their biological clocks. The book: Presents an up-to-date and thorough summary of what is known about how arthropods of agricultural and medical importance respond to visual cues.

R7,942 Discovery Miles 79 420 Ships in 12 - 17 working days

With increasing population and industrialization, our negative impact on our environment is no longer limited to coastal and surface waters or to urban air; it is necessary to examine the movement of chemical pollutants over vastly greater areas. Oceans, deep groundwater aquifers, and even the stratosphere are significantly affected. The mechanisms by which pollutants reach these areas, how they migrate and are transformed through physical and biochemical processes, and their ultimate effects are the topics at the forefront of environmental science. This volume addresses the fate of chemical pollutants in our air, water, and soil. The result of a historic collaboration between eminent Russian and American scientists, Fate of Pesticides and Chemicals in the Environment contains new predictive models of transport and transformation from many of the leading scientists in this area of research. Numerous informative chapters analyze the biotransformation of organic chemicals and pesticides, atmospheric deposition of toxic pollutants in the Great Lakes and elsewhere, the transport of volatile organic compounds and pesticide residues through surface soil, and many other important problems in the field. The sources and pathways of pollutants into all areas of the environment are thoroughly explored; the role of free radicals in chemical transformations, surface and bottom sediment redox reactions in water, the contribution of microbial degradation, and considerations for in situ biorestoration are just a few of the complex issues addressed. The book also contains comprehensive information on pesticide labeling laws and groundwater protection which will be of interest to all soil and waterchemists and environmental engineers.

In this fascinating book, Graham Matthews takes the reader through the history of the development and use of chemicals for control of pests, weeds, and vectors of disease. Prior to 1900 only a few chemicals had been employed as pesticides but in the early 1940s, as the Second World War raged, the insecticide DDT and the herbicide 2-4-D were developed. These changed everything. Since then, farmers have been using a growing list of insecticides, herbicides and fungicides to protect their crops. Their use has undoubtedly led to significant gains in agricultural production and reduction in disease transmission, but also to major problems: health concerns for both users of pesticides and the general public, the emergence of resistance in pest populations, and environmental problems. The book examines the development of legislation designed to control and restrict the use of pesticides, the emergence of Integrated Pest Management (IPM) and the use of biological control agents as part of policy to protect the environment and encourage the sustainable use of pesticides. Finally, the use of new technologies in pest control are discussed including the use of genetic modification, targeted pesticide application and use of drones, alongside basic requirements for IPM such as crop rotations, close seasons and adoption of plant varieties with resistance to pests and diseases.

R4,705 Discovery Miles 47 050 Ships in 12 - 17 working days

In the first chapter of the book, the immunotoxicological risk arising from xenogenous substances is emphasised. Immunotoxicology investigates unwanted adverse effects of xenobiotics on the immune system of man and animals. With regards to insecticides and pest control, several studies showed that the insect endocrine system, especially anti-stress neuropeptides, could be used as a potential target for pest control. The second chapter examines the enhancement of insecticide efficacy specifically by adipokinetic hormones. In the third chapter, the authors propose, based on their research, that the combined use of different methods such as the use of biological control agents of insect vectors of aflatoxigenic fungi, plus the use of food grade antioxidants in sublethal doses, could help reduce aflatoxins in stored maize. Maize is a crop of major economic importance in the world because it is used as human and/or livestock feed. This chapter reviews the integrated management of insect vectors of aflatoxigenic fungi in stored maize. The fourth and last chapter of this book summarises the relationship between soil nematode communities as bioindicators of soil health and quality and application of insecticides used for the control of Western corn rootworm (WCR) in the maize field.

International Agency for Research on Cancer
R1,431 Discovery Miles 14 310 Ships in 10 - 15 working days

Evaluates the carcinogenic risk to humans posed by occupational exposure during the spraying and application of insecticides. The book also features separate monographs evaluating the carcinogenicity of 17 individual pesticides, including several that have been banned by industrialized countries yet are still used in the developing world. Although some of these pesticides have been in use for more than four decades, evaluations of carcinogenicity were hindered by the sparsity of well-designed epidemiological studies. The first and most extensive monograph evaluates data from descriptive and ecological studies, cohort studies, and case-control studies suggesting an increased risk of cancer, most notably lung cancer, multiple myeloma and other tumours of B-cell origin, in workers exposed to insecticides during their application. On the basis of this evaluation, the book concludes that the spraying and application of nonarsenical insecticides entail exposures that are probably carcinogenic to humans. The remaining monographs evaluate the carcinogenicity of aldicarb, atrazine, captafol, chlordane, DDT, deltamethrin, dichlorvos, fenvalerate, heptachlor, monuron, pentachlorophenol, permethrin, picloram, simazine, thiram, trifluralin, and zitram. Of these, captafol, a fungicide used on plants, for seed treatment, and as a wood preservative, was classified as probably carcinogenic to humans. Atrazine, chlordane, DDT, dichlorvos, heptachlor, and pentachlorophenol were classified as possibly carcinogenic to humans. The remaining pesticides could not be classified on the basis of available data.

Stored product insects and other pests represent a major hygiene and safety issue to many industries, from food production to building infestation, and issues for timber pallets and packaging. Beds bugs are rapidly becoming a public health issue in hotels, hostels and houses in many parts of the world. While fumigation has been one of the prevalent routes for pest control, there remain issues with the toxicity of the chemicals used and potential exposure to humans therefore heat treatment has proven to be a successful alternative when used correctly.

It is well known that excessive heat is dangerous to life. There is a difference between the amount of heat required to kill microbes such as bacteria and viruses and that required to kill larger life forms such as insects or mammals. This book focuses on the use of heat to kill insects and mites in food production, storage and other facilities.

Heat Treatment for Insect Control examines how controlled heat treatment kills all stages of pest insect life across species and without causing damage to surrounding structures or electronics. The advantages of heat treatment include no health & safety hazards, a completely controllable and environmentally friendly process, reduced treatment time of fumigation (hours verses days), as well as no factory shutdown or exclusion of staff from adjacent areas during treatment.

Part I reviews the principles of heat treatment, with chapters covering the fundamentals, planning, best practice and costs of integrated pest management. Part II looks at heat treatment applications in food production, storage, food materials and fresh produce. Part III examines the other applications in clothing, small rooms, buildings, and transportation.
Provides a comprehensive and systematic reference on the heat treatment for insect controlReviews the development of heat treatment processes and technology as part of integrated pest management approaches

Pests are defined purely from anthropocentric perspective. An organism is not considered a pest until its activities and life processes interfere with human health, convenience, comfort or profits. The importance of health education in the control of vector-borne diseases cannot be overstated. This should particularly be targeted at rural communities where the scourges of these diseases are most pronounced. With adequate commitment by the government at the federal, state and local levels as well as from private sectors, considerable success could be achieved in the battle against pests. This book represents an excellent addition to the literature on Integrated Pest Management (IPM). A historical overview traces the origins and concepts of pest organisms, their classification and general characteristics and the basic terminologies are given. The philosophy and goal of IPM and specific examples of chemical, cultural, biological, physical and mechanical approaches to IPM are discussed. The book is enriched with accounts of IPM practices and progression in the developing countries and the problems and prospects of implementation and the future of IPM highlighted. Also included is an interesting account of medical important arthropods and their management. A rich bibliography accompanies every chapter.

Palladium is a steel-white, ductile metallic element resembling and occurring with the other platinum group metals and nickel. Palladium and its alloys are used in the (petro) chemical and the automotive industries as catalysts, in dentistry, and in electronics and the, electrical industry.This book evaluates the risks to human health and the environment posed by exposures to palladium. The general population is primarily exposed to palladium through dental alloys or jewellery. There were case reports referring to palladium sensitivity associated with exposure to palladium-containing dental restorations; the, symptoms being contact dermatitis, stomatitis or mucositis and oral lichen planus.Palladium ions are considered to be highly toxic to aquatic organisms. However, due to palladium's high economic value, emissions of palladium from point sources are currently minimal. Increased use of catalytic converters may increase palladium emissions from diffuse sources. It was recommended that these emissions should, be controlled to be as low as possible.

R639 Discovery Miles 6 390 Ships in 10 - 15 working days

Evaluates the risks to human health and the environment posed by exposure to dinitro-"ortho"-cresol, a chemical used for over a century as an acaricide, larvicide, and ovicide to control the dormant forms of many insects in orchards. The chemical is also sprayed on potatoes to prevent virus and disease contamination of the tubers. Although the chemical's use as a pesticide has been banned in many countries, significant volumes of obsolete stocks are still found in several parts of the world, especially in developing countries. Dinitro-"ortho"-cresol continues to be used in the plastics industry as an inhibitor of polymerization in styrene and vinyl aromatic compounds. Concerning environmental behavior studies indicate that the chemical is rapidly biodegraded in soil and has no potential to volatilize when released to water. Evidence further suggests that uptake by treated fruit trees or potatoes leaving residues at harvest time does not occur. Food is therefore not considered an important source of exposure for the general population. Occupational exposures during agricultural spraying and during manufacturing and formulation are regarded as the principal sources of human exposure. The most extensive part evaluates the results of toxicity studies in laboratory mammals and "in vitro "test systems. Short-term dietary administration decreased body-weight gain in some species, usually without significant alteration in food consumption. At high doses, adverse effects on the liver have been observed. Data on embryotoxicity, teratogenicity, mutagenicity, and carcinogenicity were judged inadequate for evaluation. The evaluation of effects on human health draws on data obtained during the limited use of dinitro-"ortho"-cresol in the 1930s as a therapeutic agent for the treatment of obesity and on cases of acute poisoning. Symptoms associated with toxicity include restlessness, flushed skin, sweating, thirst, deep and rapid respiration, severe increase of body temperature, and cyanosis leading to collapse, coma, and death. Concerning adverse effects on occupationally exposed workers, the report cites a dramatic decline over the last 25 years in reported cases of occupational intoxication. The decline is attributed to better education of users, the use of adequate protective equipment, and improvements in application techniques, equipment, and formulations. The report concludes that when used according to registered recommendations, and when measures for personal protection are followed, exposure to dinitro-"ortho"-cresol is reduced to levels that do not cause systemic toxicity.
