Download or read book Biology of the Leaf Miners written by E.M. Hering and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of specialised feeding habits during the course of time by human beings is paralleled in the majority of animals, in particular have developed special peculiarities, and insect larvae which in most cases are quite characteristic of the species concerned. This applies especially to phytophagous insect larvae, and anyone with the requisite experience can say with a fair degree of certainty which insect larva is responsible for any damage to be found on a plant. It leaves behind a definite "feeding pattern" which might be compared to a "visiting card" on which the genus and species are marked in runic characters. Whoever has learned to read the runes can readily determine who has been feeding on the affected spot, solely on the basic of the "visiting card" left behind. From the known factors - the name of the plant and the type of feeding patter- and after some study of the various types of plant infestation, both the genus and species of the larva producing the feeding pattern can be worked out without difficulty. The importance of "feeding pattern investigation" has now far outstripped the successes to be obtained by normal collecting. Previously, when wishing to list the species of insects present in any given locality they were caught with the net, by sugaring and other methods. This always resulted in a very defective "list" of the insects in fact existing in the locality concerned.

Download or read book Measuring Arthropod Biodiversity written by Jean Carlos Santos and published by Springer Nature. This book was released on 2020-11-11 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a wide range of sampling methods for investigating different arthropod groups. Each chapter is organized to describe and evaluate the main sampling methods (field methods, materials and supplies, sampling protocols, effort needed, and limitations); in addition, some chapters describe the specimen preparation and conservation, species identification, data collection and management (treatment, statistical analysis, interpretation), and ecological/conservation implications of arthropod communities. The book aims to be a reference for zoologists, entomologists, arachnologists, ecologists, students, researchers, and for those interested in arthropod science and biodiversity. We hope the book will contribute to advance knowledge on field assessments and conservation strategies. Arthropods represent the most speciose group of organisms on Earth, with a remarkable number of species and interactions still to be described. These invertebrates are recognized for playing key ecological roles in terrestrial, freshwater and marine ecosystems. Because of the increasing and relentless threats arthropods are facing lately due to a multitude of human induced drivers, this book represents an important contribution to assess their biodiversity and role in ecosystem functioning and generation of ecosystem services worldwide.

Download or read book Handbook of Biological Control written by T. W. Fisher and published by Elsevier. This book was released on 1999-09-20 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years the use of chemical agents such as pesticides and herbicides has been effective in controlling the many varieties of pests that infest both agricultural crops and backyard gardens. However, these pests are gradually becoming resistant to these agents, because the agents themselves are acting as selective factors making the pests better and better able to resist and persist. As a result, the use of biological controlling agents is increasing. This book is a comprehensive and authoritative handbook of biological control.

Available in PDF, EPUB and Kindle. Book excerpt: Genetic improvement has played a vital role in enhancing the yield potential of vegetable crops. There are numerous vegetable crops grown worldwide and variable degrees of research on genetics, breeding and biotechnology have been conducted on these crops. This book brings together the results of such research on crops grouped as alliums, crucifers, cucurbits, leaf crops, tropical underground and miscellaneous. Written by eminent specialists, each chapter concentrates on one crop and covers cytology, genetics, breeding objectives, germplasm resources, reproductive biology, selection breeding methods, heterosis and hybrid seed production, quality and processing attributes and technology. This unique collection will be of great value to students, scientists and vegetable breeders as it provides a reference guide on genetics, breeding and biotechnology of a wide range of vegetable crops.

Download or read book Food Crop Production by Smallholder Farmers in Southern Africa written by Ambayeba Muimba-Kankolongo and published by Academic Press. This book was released on 2018-02-07 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food Crop Production by Smallholder Farmers in Southern Africa: Challenges and Opportunities for Improvement evaluates traditional cultivation practices used by smallholder farmers, providing a synthesis of the latest information on increasing crop yield through adoption of research innovations. The book catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector including: management practices that reduce net carbon emissions; technologies that improve soil structures and conserve the natural resources base; means of empowering female resources along value chains; and government commitment to adopt policies that enhance agriculture productivity by encouraging farmers to use environmentally sound cultivation technologies. Traditional farming techniques often produce negative impacts on the environment and ecosystem resulting in outbreaks of diseases and pests. In addition to the region’s recurrent droughts, these outbreaks of numerous diseases and pests, weeds and other invasive plants put thousands at risk of poverty and hunger, as well as malnutrition. This book presents enhanced agricultural production technologies for ensuring adequate food production, safety and nutritional quality for the population of Southern Africa and forms the basis for an increased SADC regional effort in food production through which financial and trade institutions can improve stakeholder capacities, encourage micro-enterprise development and enhance employment and regional trade. Provides a critical synthesis of data and information for increasing crop yield through adoption of research innovations Evaluates traditional and scientific interventions that address food security issues of the poor farmers in the region Presents agro-ecologies of countries in the region and how they relate to various cultivation practices Catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector
Download or read book Reality Mining written by Nathan Eagle and published by MIT Press. This book was released on 2014-08 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the authors explore the positive potential of big data, showing the ways in which the analysis of big data ("reality mining") can be used to improve human systems as varied as political polling and disease tracking, while considering user privacy. They describe reality mining at five different levels: the individual, the neighborhood and organization, the city, the nation, and the world. For each level, they offer a nontechnical explanation of data collection methods and describe applications and systems that have been or could be built. These include a mobile app that helps smokers quit smoking; a workplace "knowledge system"; the use of GPS, Wi-Fi, and mobile phone data to manage and predict traffic flows; and the analysis of social media to track the spread of disease. The authors argue that big data, used respectfully and responsibly, can help people live better, healthier, and happier lives. --
