        Riceland Spiders of South and Southeast Asia

        by A T Barrion, Jim A Litsinger

        Spiders are among the most omnipresent and numerous predators in both agricultural and natural ecosystems, and without them insect pest populations would become out of control. Their potential as biological control agents can only be appreciated through a greater understanding of their abundance and species composition in different ecological systems. There is therefore a great need for literature providing guidance on spider identification. The spider fauna of several cultivated crops, in a number of regions of the world, has been well documented. There have been some previous attempts to record the spider fauna of rice in South and Southeast Asia, but these are scattered in the journal literature. This volume provides a comprehensive illustrated guide that can be used by specialists and novices to identify these spiders. The majority of the species covered were collected from a diversity of habitats in the Philippines. The bulk of the book consists of keys to the identification of families, genera and species of Philippine spiders, illustrated by more than 1000 line drawings and 100 colour photographs. A total of 339 species belonging to 134 genera within 26 families are recognized. Of these, 253 species and seven genera are new to science. Distribution maps for individual species and a classification scheme for Philippine riceland spiders are also provided. Overall, the work represents a major contribution to the literature for those interested in spiders or more generally in biological control and crop protection.

        A History of Pesticides

        by Graham A Matthews

        In this fascinating book, Graham Matthews takes the reader through the history of the development and use of chemicals for control of pests, weeds, and vectors of disease. Prior to 1900 only a few chemicals had been employed as pesticides but in the early 1940s, as the Second World War raged, the insecticide DDT and the herbicide 2-4-D were developed. These changed everything. Since then, farmers have been using a growing list of insecticides, herbicides and fungicides to protect their crops. Their use has undoubtedly led to significant gains in agricultural production and reduction in disease transmission, but also to major problems: health concerns for both users of pesticides and the general public, the emergence of resistance in pest populations, and environmental problems. The book examines the development of legislation designed to control and restrict the use of pesticides, the emergence of Integrated Pest Management (IPM) and the use of biological control agents as part of policy to protect the environment and encourage the sustainable use of pesticides. Finally, the use of new technologies in pest control are discussed including the use of genetic modification, targeted pesticide application and use of drones, alongside basic requirements for IPM such as crop rotations, close seasons and adoption of plant varieties with resistance to pests and diseases.

        An Historical Atlas of Staffordshire

        by A. D. M. Phillips, C. B. Phillips

        Within its ancient boundaries, Staffordshire is a county of diverse and contrasting historic landscapes. World-renowned industrial complexes sit alongside agricultural systems; castles rub shoulders with urban-industrial housing; the cathedral centre of a vast diocese lies close to the birthplace of primitive Methodism; overtly planned landscapes mingle with the uplands of the Moorlands and the heathlands of Cannock Chase. These many and varied landscapes are both products and reflections of a multiplicity of histories, and students of the county have been keen to explore and relate these pasts. However, no systematic attempt has previously been made to express these accounts in spatial form. This book seeks to demonstrate by maps the various histories that contribute to the diversity of Staffordshire. With its succinct discussions and detailed map presentations of these themes, incorporating new thinking and recent research, the atlas provides an innovative and major contribution to the study of the history of Staffordshire. ;

        How a Satellite Works

        by Joseph A. Angelo, Jr.

        Designed to help students and teachers better appreciate science and engineering in a global context, this eBook starts with a discussion of the physics of orbiting objects, including the concepts of free fall and microgravity, followed by an explanation of how engineers put a satellite into orbit around Earth. It also describes the basic differences and common components of modern human-made satellites and discusses the growing problem of space debris and the fate of old or broken satellites. A wealth of images help bring the topic to life.

        Asian Citrus Psyllid

        Biology, Ecology and Management of the Huanglongbing Vector

        by Jawwad A. Qureshi, Philip A. Stansly

        Asian citrus psyllid (ACP), Diaphorina citri, is an insect pest which transmits a bacterium, Candidatus liberibacter asiaticus (Clas) through newly emergent foliage of citrus trees. This causes a disease known as Huanglongbing (HLB), which has become the most debilitating and intractable disease in citrus crops. This book, written by a team of experts on the Asian citrus psyllid, gathers together everything currently known about the biology and ecology of this important pest species, examines the transmission and acquisition processes of the pathogen, and looks at current management practices and their effectiveness. The potential for new, innovative management techniques are also described along with the economic implications of managing this rapidly establishing disease.

        The Moon as a Platform for Astronomy and Astrophysics

        by Joseph A. Angelo, Jr.

        The prospect of establishing a permanent lunar base could give scientists the extraordinary ability to use the Moon as a platform for future efforts in space-based astronomy and astrophysics. This eBook introduces a lunar-base development scenario that spans the 21st century and describes several concepts for astronomy performed on the surface of the Moon. As NASA collaborates with commercial and international partners to establish sustainable exploration by 2028, this eBook is an essential read for the scientists of tomorrow.

        Arctic state identity

        Geography, history, and geopolitical relations

        by Ingrid A. Medby

        This book sets out to answer what it means to hold a formal title as one of the eight 'Arctic states'; is there such a thing as an Arctic state identity, and if so, what does this mean for state personnel? It charts the thoughtful reflections and stories of state personnel from three Arctic states: Norway, Iceland, and Canada, alongside analysis of documents and discourses. This book shows how state identities are narrated as both geographical and temporal - understood through environments, territories, pasts and futures - and that any identity is always relational and contextual. As such, demonstrating that to understand Arctic geopolitics we need to pay attention to the people whose job it is to represent the state on a daily basis. And more broadly, it offers a 'peopled' view of geopolitics, introducing the concept and framework of 'state identity'.
