Download or read book Insect Diversity and Ecosystem Services written by Younis Ahmad Hajam and published by CRC Press. This book was released on 2024-08-30 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new innovative work on insects and their impact on the ecosystem covers the role of insects in environmental pollution, their use in sustainable agricultural services, and the industrial, forensic, and medical applications of insects and their pure products. The book also covers the entomological and molecular aspects of insects, identifies the gaps in the research, and looks at integrated management strategies for pests. Volume 1: Importance, Threats, Conservation, and Economic Perspectives, reviews the different insect orders regarding their diversity and importance in providing free ecological services and discusses the diversity patterns of world biogeographic zones and how insects contribute to maintaining ecological diversity. Volume 2: Environmental Indicators, Molecular Approaches, and Management Strategies discusses the role of insects as environmental indicators, the effect of pesticides on insect diversity, strategies to control the diversity of insects, medical and forensic importance of insects, exploring new insect species through DNA barcoding, integrated pest management, the role of insect population in agriculture, and eco-friendly pest management approaches. Some topics covered in the book include: Role of insects for the sustainable agricultural development Commercial importance of insects and their products Food additive roles of insects and formulation of remedies for the reduction of disease pathogenesis Management strategies for pest control Some specific topics include colony collapse disorder of managed honey bee (Apis mellifera l.) populations, insects as strong crime indicator tools in forensic sciences, insect-based value-added products, and more. Together, these two volumes offer important information for researchers, academicians, scientists, industrialists, teachers, entomologists, and students for understanding the contribution of insects towards the sustainability of the ecosystem.

Available in PDF, EPUB and Kindle. Book excerpt: The essential guide for identifying the bumble bees of North America More than ever before, there is widespread interest in studying bumble bees and the critical role they play in our ecosystems. Bumble Bees of North America is the first comprehensive guide to North American bumble bees to be published in more than a century. Richly illustrated with color photographs, diagrams, range maps, and graphs of seasonal activity patterns, this guide allows amateur and professional naturalists to identify all 46 bumble bee species found north of Mexico and to understand their ecology and changing geographic distributions. The book draws on the latest molecular research, shows the enormous color variation within species, and guides readers through the many confusing convergences between species. It draws on a large repository of data from museum collections and presents state-of-the-art results on evolutionary relationships, distributions, and ecological roles. Illustrated keys allow identification of color morphs and social castes. A landmark publication, Bumble Bees of North America sets the standard for guides and the study of these important insects. The best guide yet to the 46 recognized bumble bee species in North America north of Mexico Up-to-date taxonomy includes previously unpublished results Detailed distribution maps Extensive keys identify the many color patterns of species

Download or read book The Natural History of Bumblebees written by Carol Ann Kearns and published by Boulder Colo. : University Press of Colorado. This book was released on 2001 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Natural History of Bumblebees, biologists Carol A. Kearns and James D. Thomson give amateurs and professionals alike the basic knowledge to pursue the joys of observing and investigating these attractive and amenable subjects. Packed with information on bumblebee colonies, bee honeypots, bee development, foraging behavior, as well as instructions for maintaining bumblebees in captivity, this lively and colorful book also includes an easy-to-use photographic field guide to aid in the identification of over fifty species of North American bumblebee-virtually every known species on this continent. Until now, even the basic identification of North American bumblebees has been through the use of highly technical regional keys. The Natural History of Bumblebees fills a gap in the literature and provides amateur enthusiasts, educators, and scholars the information to develop their own projects in bumblebee biology. Kearns and Thomson also provide detailed instructions for constructing simple equipment that facilitates bee wrangling: the handling, tagging, studying, and raising of bumblebees. They present suggestions for research projects and identify areas of incomplete knowledge requiring further research. This book is an invaluable reference for students and scholars of native pollinators and an indispensable resource for naturalists, gardeners, and anyone who has ever been fascinated by the flight of the bumblebee.

Download or read book Asian Beekeeping in the 21st Century written by Panuwan Chantawannakul and published by Springer. This book was released on 2018-06-01 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the perspective of local scientists, this book provides insight into bees and bee management of Asia, with a special focus on honey bees. Asia is home to at least nine honey bee species, including the introduced European honey bee, Apis mellifera. Although A. mellifera and the native Asian honey bee, Apis cerana, are the most commonly employed species for commercial beekeeping, the remaining non-managed native honey bee species have important ecological and economic roles on the continent. Species distributions of most honey bee species overlap in Southeast Asia, thus promoting the potential for interspecies transmission of pests and parasites, as well as their spread to other parts of the world by human translocation. Losses of managed A. mellifera colonies is of great concern around the world, including in Asia. Such global colony losses are believed to be caused, in part, by pests and parasites originating from Asia such as the mite Varroa destructor, the microsporidian Nosema ceranae, and several bee viruses. Taking advantage of the experience of leading regional bee researchers, this book provides insight into the current situation of bees and bee management in Asia. Recent introductions of honey bee parasites of Asian origin to other parts of the world ensures that the contents of this book are broadly relevant to bee scientists, researchers, government offi cials, and the general public around the world.

Available in PDF, EPUB and Kindle. Book excerpt: Several reports of North American bumble bee (Bombus Latreille) decline have been documented across the continent, but no study has fully assessed the geographic scope of decline. In this study I discuss the importance of Natural History Collections (NHC) in estimating historic bumble bee distributions and abundances, as well as in informing current surveys. To estimate changes in distribution and relative abundance I compare historic data assembled from a>73,000 specimen database with a contemporary 3-year survey of North American bumble bees across 382 locations in the contiguous U.S.A. Based on my results, four historically abundant bumble bees, B. affinis, B. occidentalis, B. pensylvanicus and B. terricola, have declined by 72 - 96% relative abundance across their native distribution, while B. bifarius, B. bimaculatus, B. impatiens, and B. vosnesenskii appear to be relatively stable. Finally, I provide some notes on the distribution, abundance, and frequency of Nosema bombi infections in Alaskan B. occidentalis.
