Download or read book Parasitoids written by H. Charles J. Godfray and published by Princeton University Press. This book was released on 2019-12-31 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitoids lay their eggs on or in the bodies of other species of insect, and the parasitoid larvae develop by feeding on the host, causing its eventual death. Known for a long time to applied biologists for their importance in regulating the population densities of economic pests, parasitoids have recently proven to be valuable tools in testing many aspects of evolutionary theory. This book synthesizes the work of both schools of parasitoid biology and asks how a consideration of evolutionary biology can help us understand the behavior, ecology, and diversity of the approximately one to two million species of parasitoid found on earth. After a general introduction to parasitoid natural history and taxonomy, the first part of the book treats the different components of the reproductive strategy of parasitoids: searching for a host, host selection, clutch size, and the sex ratio. Subsequent chapters discuss pathogens and non-Mendelian genetic elements that affect sexual reproduction; evolutionary aspects of the physiological interactions between parasitoid and host; mating strategies; life history theory and community ecology. A special effort is made to discuss the theoretical background to the subject, but without the use of mathematics.

Available in PDF, EPUB and Kindle. Book excerpt: Organic Crop Breeding provides readers with a thorough review of the latest efforts by crop breeders and geneticists to develop improved varieties for organic production. The book opens with chapters looking at breeding efforts that focus on specific valuable traits such as quality, pest and disease resistance as well as the impacts improved breeding efforts can have on organic production. The second part of the book is a series of crop specific case studies that look at breeding efforts currently underway from around the world in crops ranging from carrots to corn. Organic Crop Breeding includes chapters from leading researchers in the field and is carefully edited by two pioneers in the field. Organic Crop Breeding provides valuable insight for crop breeders, geneticist, crop science professionals, researchers, and advanced students in this quickly emerging field.

Download or read book Drosophilidae Diptera written by Irina Brake and published by BRILL. This book was released on 2013-01-21 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. Volumes in this series contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e.g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume nine focuses on Drosophilidae (Diptera).

Download or read book Biological Control written by Peter G. Mason and published by CSIRO PUBLISHING. This book was released on 2021-10-01 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Control: Global Impacts, Challenges and Future Directions of Pest Management provides a historical summary of organisms and main strategies used in biological control, as well as the key challenges confronting biological control in the 21st century. Biological control has been implemented for millennia, initially practised by growers moving beneficial species from one local area to another. Today, biological control has evolved into a formal science that provides ecosystem services to protect the environment and the resources used by humanity. With contributions from dedicated scientists and practitioners from around the world, this comprehensive book highlights important successes, failures and challenges in biological control efforts. It advocates that biological control must be viewed as a global endeavour and provides suggestions to move practices forward in a changing world. Biological Control is an invaluable resource for conservation specialists, pest management practitioners and those who research invasive species, as well as students studying pest management science.

Download or read book Insect Chemical Ecology written by Bernard D. Roitberg and published by Springer Science & Business Media. This book was released on 1992-08-31 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect Chemical Ecology provides a comprehensive view of how natural selection acts upon interacting organisms and how particular physical and biological properties of chemical compounds act as constraints upon which natural selection may act. Individual chapters raise specific questions as to the nature of these interactions. The first part contains reviews on antagonistic and mutualistic chemical interactions, the `raw materials' of chemical evolution, the economics of offensive and defensive chemicals, and neurobiology. The second part discusses particular problems such as the evolution of resistance, insect pollination, learning, pheromones, sequestration of semiochemicals, the role of microorganisms, sex attractants, the evolution of host races and biotypes, and the role of semiochemicals and the evolution of sociality of insects. The last chapter discusses the role of chemical-based pest management programs in an ecological and evolutionary framework.

Download or read book Partnerships in Communities written by Jean Richardson and published by . This book was released on 2000 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Partnerships in Communities" provides a fresh perspective on sustainable rural community development, offering community-based and community-driven responses to the challenges facing rural America. Author Jean Richardson draws on her many years of experience working in rural areas both at home and abroad to offer an integrated and practical approach to rural community development. Some of the findings presented are derived from a comprehensive project known as Environmental Partnerships in Communities (EPIC), which Richardson has directed for the past seven years in Vermont. From this experience and those of others from across America, Richardson provides a wealth of insight regarding what works, what doesn't, and how financial and human resources can be most effectively focused in rural communities.Following an introductory chapter that describes what is happening in rural America today and examines the institutions and natural resource base upon which rural communities depend, the book: addresses the need for self-directed community development sets forth a comprehensive approach based on the EPIC experience describes efforts to revitalize working rural landscapes, including organization building, pasture management, historic preservation, and more uses case studies and personal stories of rural people to portray the critical role of leadership in community stewardship and conservation.At the end of each chapter, the author synthesizes the transferable lessons learned, and the book concludes with a chapter that draws together those lessons to suggest a dynamic new approach to rural development. Numerous photographs enliven the text, and an extensive bibliography and a rich set ofappendixes provide resources for additional information."Partnerships in Communities" will serve as an invaluable source of inspiration and ideas for rural community leaders, citizen groups, public officials, planners, students of rural planning and community development, and nonprofit organizations involved with rural development.
