Fundamentals of Stored-Product Entomology


Book Description

This reference discusses the fundamentals of stored-product entomology that need to be considered in planning, implementation, and evaluation of a pest management program. It is based on the review of an extensive database of references and many years of research on stored-product insect problems by the expert authors. The information in this book helps answer consumers’ concern about pesticide residues in food by providing helpful IPM and alternative approaches for pest management. It provides the basic information needed to manage pests with and without the use of chemicals. Managing pests requires a thorough understanding of insect biology, behavior, ecology, sampling, pros and cons of management options, and responses of insects to the various management options. This comprehensive book covers all of these topics, beginning with a discussion of the scope of stored-product entomology. It also provides insight into the diversity of foods and habitats utilized by stored-product insects, the types of economic losses attributable to them, and the ways in which an understanding of their biology can be used to study or manage these insects. Insect mobility, sources of insect infestation, sampling, life history, and population growth are discussed as well, as they play an important role in developing an effective sampling program. In addition, decision aids, the cost of management methods, and the resistance of insects to management methods are covered. For insight into the thought process of choosing treatment options, eight pest management methods are thoroughly described, including a statement of the basic operating principle and background information. For help choosing various chemical and nonchemical methods for diverse situations, the advantages, disadvantages and implementation options for each method are given. Students, extension educators, consultants, food industry sanitarians and managers, legislators, regulators, and insect pest management professionals are sure to find information that will help them to improve pest management. Study questions at the end of each chapter Suggested supplemental reading, including books, conference proceeding papers, literature reviews, research papers, government publications, and popular articles General overview of the biology for a basic understanding of pest control issues Guides the reader through the thought process of designing a pest control program or research study Images of the most damaging of stored-product insect pest species for identification of families Quick methods for distinguishing closely related stored-product insect species

Aeolian Dust and Dust Deposits


Book Description

Aeolian Dust and Dust Deposits explores the entrainment, dispersion, and deposition of aeolian dust and dust deposits, with emphasis on transport and deposition of dust derived by deflation of surface sediments and soils. Topics covered range from the mechanisms of fine-particle formation to dust sources, sinks, and rates of deposition. Dust-transporting wind systems are also discussed, along with the grain size, mineralogy, and chemical composition of aeolian dust. Comprised of nine chapters, this book begins with an overview of the general nature and significance of windborne dust as well as the importance of aeolian dust and loess. The next chapter deals with the mechanisms underlying the formation of fine particles, including glacial grinding, frost and salt weathering, and fluvial comminution. The reader is then introduced to dust entrainment, transport, and deposition, together with dust sources, sinks, and rates of deposition. Subsequent chapters focus on the implications of dust deflation, transport, and deposition; dust deposition in the oceans; and loess distribution and the thickness and morphology of loess deposits. This monograph is written primarily for research workers and advanced students in sedimentology, geomorphology, and Quaternary studies, but is also likely to be of value to soil scientists, meteorologists, planetary geologists, engineers, and others concerned with environmental management.




An Introduction to the Physics of Interstellar Dust


Book Description

A concise reference, this book provides overview of interstellar dust and the interstellar medium. Emphasizing and explaining astronomical formulae, it addresses the absorption and scattering of dust, its creation in old stars, as well as emission, cohesion, and electrical charge. The book offers numerous figures displaying basic properties of dust such as optical constants, specific heat, and absorption and scattering coefficients. It introduces radiative transfer in a dusty medium and describes the use of transfer codes. With strong attention to detail, the author facilitates a complete understanding from which to build a more versatile application and manipulation of the information.

A Grain of Sand


Book Description

"To see a world in a grain of sand, And a heaven in a wild flower. To hold infinity in the palm of your hand, And eternity in an hour." William Blake, "Auguries of Innocence"1805 Here is the world viewed within a grain of sand, thanks to the stunning three-dimensional microphotography of Dr. Gary Greenberg. To some, all sand looks alike--countless grains in a vast expanse of beach. Look closer--much closer--and your view of sand will never be the same. Employing the fantastic microphotographic techniques that he developed, Greenberg invites readers to discover the strange and wonderful world that each grain of sand contains. Here are the sands of Hawaii and Tahiti, the Sahara and the Poles, a volcano, each exquisitely different, and each telling a fascinating geological story. Red sand and yellow, white sand and black, singing sand and quicksand: Greenbergs pictures reveal the subtle differences in their colors, textures, sizes, and shapes. And as this infinitesimal world unfolds so does an intriguing explanation of how each grain of sand begins and forms and finds itself in a particular place, one of a billion and one of a kind.
