Book Description
Leafhopper Vectors and Plant Disease Agents is the second in a multivolume series on vectors, vector-borne disease agents, and plant disease spread. This text aims to collect findings in leafhopper vector research, to suggest promising frontiers for further research, and to call attention to possible practical applications of understanding of leafhopper-pathogen-plant interactions. This book is organized into five parts. Opening chapters on the taxonomy, bionomics, and worldwide importance of leafhopper and planthopper vectors are appropriately relegated to Parts I and II. Part III focuses on vector-virus interactions of leafhopper-, planthopper-, and aphid-borne viruses and virus-induced, cytopathological changes in vectors. This part also explains the interactions of mycoplasmalike organisms (MLOs) and viruses in dually infected leafhoppers, planthoppers, and plants, as well as the transitory vector-virus interactions. The artificial and aseptic rearing of vectors, microinjection technique, vector tissue culture, and spiroplasmas and its vectors are all covered in Part IV. Part V contains chapters on specific leafhopper-borne viruses and MLOs, leafhopper and planthopper vector control, leafhopper-borne pathogens of corn-stunting diseases, Western X disease, and leafhopper-borne xylem-restricted pathogens. This text will be valuable for students, teachers, and researchers of vector-pathogen-plant relationships. Its in-depth coverage of leafhoppers and planthoppers as vectors makes this book ideally suited as a supplemental text in graduate entomology and plant pathology courses on insect transmission of plant disease agents.

Book Description
Volume Two of the new guide to the study of biodiversity in insects Volume Two of Insect Biodiversity: Science and Society presents an entirely new, companion volume of a comprehensive resource for the most current research on the influence insects have on humankind and on our endangered environment. With contributions from leading researchers and scholars on the topic, the text explores relevant topics including biodiversity in different habitats and regions, taxonomic groups, and perspectives. Volume Two offers coverage of insect biodiversity in regional settings, such as the Arctic and Asia, and in particular habitats including crops, caves, and islands. The authors also include information on historical, cultural, technical, and climatic perspectives of insect biodiversity. This book explores the wide variety of insect species and their evolutionary relationships. Case studies offer assessments on how insect biodiversity can help meet the needs of a rapidly expanding human population, and examine the consequences that an increased loss of insect species will have on the world. This important text: Offers the most up-to-date information on the important topic of insect biodiversity Explores vital topics such as the impact on insect biodiversity through habitat loss and degradation and climate change With its companion Volume I, presents current information on the biodiversity of all insect orders Contains reviews of insect biodiversity in culture and art, in the fossil record, and in agricultural systems Includes scientific approaches and methods for the study of insect biodiversity The book offers scientists, academics, professionals, and students a guide for a better understanding of the biology and ecology of insects, highlighting the need to sustainably manage ecosystems in an ever-changing global environment.

Book Description
This guide describes the steps that national plant protection organizations (NPPOs) should follow when determining the status of a pest in an area, starting with identifying the pest and the area under consideration. It provides guidance on gathering and evaluating information, assessing sources of uncertainty, and how to use pest records and other relevant information to determine whether a pest is absent or present in the area and then to select the appropriate pest status category, as described in ISPM 8 (Determination of pest status in an area). This includes guidance on determining whether a pest is expected to establish in an area, and whether it is widely distributed or under official control. The guide describes the responsibilities of NPPOs when determining the status of pests within their territories, the requirements for national legislation to support actions relevant to pest status and how pest status determination fits within the international phytosanitary framework. It also describes how the outcomes of pest status determination may be used to support other key activities, such as preparing regulated pest lists, pest reporting, and securing or maintaining market access. Finally, the guide provides a number of case studies from around the world that highlight different aspects of the pest status determination process and how NPPOs deal with particular issues. By providing a deeper understanding of the process and the factors that should be considered when determining pest status, the guide aims to improve consistency in the processes used by NPPOs to make pest status determinations.

Book Description
The present edition may be regarded as a descendant, much changed and greatly enlarged, of the late Dr A. D. Imms' Outlines of Entomology, first published in 1942. This went through three further editions without much change, but after the death of the original author a fifth, revised edition by Professor o. W. Richards and myself appeared in 1959 and a sixth in 1978. The book now appears in a considerably extended version in which I have tried to provide a more balanced introduction to the whole field of modern entomology by dealing with several aspects of the subject not discussed at all in previous editions. Thus, in addition to innumerable lesser changes in the sections on insect structure, function, development, classification and phylogeny, I have completely recast the earlier chapter on some important modes of life in insects. This now includes a far wider range of biological topic;s well exemplified by the insects and should, I hope, appeal not only to, those already dedicated to entomology but also to others with more general biological interests. A completely new chapter on the biology of insect populations has also been added and may serve to indicate the debt which modern ecological theory owes to work on insect populations. It should hardly be necessary to apologize for introducing a certain amount of elementary mathematics into this account of a subject which is now among the most highly quantitative of biological disciplines.

00 This is the first comprehensive guide to insect life in a part of the world known for its abundant, and endangered, life forms. Charles Hogue's scholarship embraces vast geographical territory--Mexico, Central and South America, and the Caribbean. Color photographs and first-rate drawings illustrate the clearly written text.

Book Description
In his preface to early editions of this book, the late Dr. A. D. Imms said that he intended it to be an elementary account of entomology as a branch of general biology. He had especiaHy in mind the needs of university students of zoology and agriculture, as weH as those intending later to specialize in entomology, and he suggested that the book might also interest teachers of advanced biology in schools. These general aims and the balance between the different aspects of the subject have changed linIe in this and in our previous revision. We have, however, tried to bring the present edition up to date on the lines of our revised tenth edition of Imms' General Textbook 0/ Entomology, published in 1977. The text has been entirely re-set and eleven illustrations have been replaced by new figures. The same orders of insects are recognized as in the last edition, but the sequence in which the Endopterygote groups appear has been changed to reflect more accurately their probable evolutionary relationships. Many small changes and some addi tions have been made in the physiological sections, the chapter on the origin and phylogeny of insects has been rewritten, and a new bibliography provides a selection of modern references for the in tending specialist. It has been our object to make these alterations without materially increasing the length of the book or its level of difficulty.
