Book excerpt: Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.

Download or read book Ecology and Evolution of Dung Beetles written by Leigh W. Simmons and published by John Wiley & Sons. This book was released on 2011-05-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the evolutionary and ecological consequences of reproductive competition for scarabaeine dung beetles. As well as giving us insight into the private lives of these fascinating creatures, this book shows how dung beetles can be used as model systems for improving our general understanding of broad evolutionary and ecological processes, and how they generate biological diversity. Over the last few decades we have begun to see further than ever before, with our research efforts yielding new information at all levels of analysis, from whole organism biology to genomics. This book brings together leading researchers who contribute chapters that integrate our current knowledge of phylogenetics and evolution, developmental biology, comparative morphology, physiology, behaviour, and population and community ecology. Dung beetle research is shedding light on the ultimate question of how best to document and conserve the world's biodiversity. The book will be of interest to established researchers, university teachers, research students, conservation biologists, and those wanting to know more about the dung beetle taxon.

Download or read book Evolutionary Biology and Conservation of Dung Beetles written by C. H. Scholtz and published by Andersen Press (UK). This book was released on 2009 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a relatively small group of insects, dung beetles have attracted an inordinate amount of scientific interest over the years. This started with the work of the famous French naturalist Jean-Henri Fabre about 100 years ago, but it the work of Gonzalo Halffter of Mexico, and his colleagues, who first placed dung beetles on the scientific map by the publication of two important synthetic works. The first was published in 1966 ("Natural History") and this was followed by another in 1982 ("Nesting and Breeding Behaviour"). A multi-authored book on dung beetle ecology, edited by Ilkka Hanski and Yves Cambefort, was published in 1991. These volumes are long out of print and mostly unavailable. In the 18 years since the last book was published there has been a steady stream of research published on dung beetle phylogeny, biogeography, physiological ecology and conservation, fields that were not, or barely treated in the previous books. The current work synthesises and updates most of the major elements covered in those studies, but introduces several novel sections in a phylogenetic approach to the natural history of dung beetles. The aspects covered, in five sections, are the following: evolution and ecological success of dung beetles; physiological and behavioural ecology of dung beetles; phylogeny of the Scarabaeinae; historical biogeography of the Scarabaeinae and its physical and biotic drivers; and, conservation of dung beetles. The content of the book is balanced in such a way that the information contained in it should be of interest to general entomologists, research specialists on dung beetle natural history, insects systematists, students of entomology, agricultural scientists and insect conservationists.

Download or read book Sterile Insect Technique written by Victor A. Dyck and published by CRC Press. This book was released on 2021-01-06 with total page 1493 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sterile insect technique (SIT) is an environment-friendly method of pest control that integrates well into area-wide integrated pest management (AW-IPM) programmes. This book takes a generic, thematic, comprehensive, and global approach in describing the principles and practice of the SIT. The strengths and weaknesses, and successes and failures, of the SIT are evaluated openly and fairly from a scientific perspective. The SIT is applicable to some major pests of plant-, animal-, and human-health importance, and criteria are provided to guide in the selection of pests appropriate for the SIT. In the second edition, all aspects of the SIT have been updated and the content considerably expanded. A great variety of subjects is covered, from the history of the SIT to improved prospects for its future application. The major chapters discuss the principles and technical components of applying sterile insects. The four main strategic options in using the SIT — suppression, containment, prevention, and eradication — with examples of each option are described in detail. Other chapters deal with supportive technologies, economic, environmental, and management considerations, and the socio-economic impact of AW-IPM programmes that integrate the SIT. In addition, this second edition includes six new chapters covering the latest developments in the technology: managing pathogens in insect mass-rearing, using symbionts and modern molecular technologies in support of the SIT, applying post-factory nutritional, hormonal, and semiochemical treatments, applying the SIT to eradicate outbreaks of invasive pests, and using the SIT against mosquito vectors of disease. This book will be useful reading for students in animal-, human-, and plant-health courses. The in-depth reviews of all aspects of the SIT and its integration into AW-IPM programmes, complete with extensive lists of scientific references, will be of great value to researchers, teachers, animal-, human-, and plant-health practitioners, and policy makers.
Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Download or read book Forest entomology in West Tropical Africa Forest insects of Ghana written by Michael R. Wagner and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a great honor and indeed a privilege for me to write the Foreword to this book, the first of its kind from the Forest Products Research Institute The study of forest insects is now becoming a matter of great concern to many people all over the world because insects damage the already depleted forests and forest resources. In Ghana very little interest was shown in the insects of forest trees and products. But as forest practices have become more intensive so also have the pests on the crops increased and the damage caused increased to alarming proportions. Foresters are now becoming in creasingly aware of the immense havoc that some of these insects can cause. To aid the fight against the pests they have to be fully identified and studied so that effective control measures can be implemented. It is in an effort to bridge this gap in our knowledge that one welcomes this book by Professor Michael R. Wagner, Dr. S.K.N. Atuahene and Dr.
