The original stimulus which started KENNETH SPENCER on a study of the Agro myzid flies was an invitation, which he accepted, to translate from the German the monograph on Leaf Miners by Professor E. M. HERING. From this developed nearly 20 years of collaboration until Professor HERING's death in 1967. Dr. SPENCER has himself described over 600 new species in the family, many of which he collected and reared from known host plants during his extensive travels to all the five main continents. Largely as a result of his work, the number of species known in Britain has increased from 90 in 1945 to 313 today. He is thus uniquely qualified to write this book about the hundred and fifty or so species which are regularly associated with cultivated plants. Much of the taxonomic detail provided here will be of value primarily to specialists; but with the help of a microscope and the botanical host list (Chapter 2) and the numerous illustrations (mostly prepared by ANN SPENCER) those in agri cultural institutes and elsewhere should now be able to identify the majority of species found attacking crops in any part of the world.

Flies (Dipteria) have had an important role in deepening scientists'understanding of modern biology and evolution. The study of flies has figured prominently in major advances in the fields of molecular evolution, physiology, genetics, phylogenetics, and ecology over the last century. This volume, with contributions from top scientists and scholars in the field, brings together diverse aspects of research and will be essential reading for entomologists and fly researchers.

The first volume to appear in a new series of handbooks deals with the ca. 115 families of Diptera (flies and Mosquitoes) known or suspected to occur in the islands of Malesia. Diptera constitute one of the larger orders of insects, and are generally considered to be a taxonomically difficult group, even at the family level. They include various economically important groups, some for example acting as vectors of diseases in man and cattle, while others are beneficial in pest control by virtue of their parasitic of predatory habits. In this work, each family is characterised, and a key using characters of the adult insects enables identification to family level. In addition, information is provided on biology, ecology, economic importance, distribution, and status of taxonomic knowledge, with key references to each family. It further includes an introduction to the higher classification, general biology and morphology, with an extensive glossary. The text is illustrated with more than 200 line drawings. An exhaustive and up-to-date list of references facilitates access to the pertinent literature. For this book, the author has worked together with world specialists of the respective families. The Families of Diptera of the Malay Archipelago will be an indispensable tool for all those working in the fields of ecology, systematic biology, and conservation, as well as applied biology.

Sustainable Management of Arthropod Pests of Tomato provides insight into the proper and appropriate application of pesticides and the integration of alternative pest management methods. The basis of good crop management decisions is a better understanding of the crop ecosystem, including the pests, their natural enemies, and the crop itself. This book provides a global overview of the biology and management of key arthropod pests of tomatoes, including arthropod-vectored diseases. It includes information that places tomatoes in terms of global food production and food security, with each pest chapter including the predators and parasitoids that have specifically been found to have the greatest impact on reducing that particular pest. In-depth coverage of the development of resistance in tomato plants and the biotic and abiotic elicitors of resistance and detailed information about the sustainable management of tomato pests is also presented. - Provides basic biological and management information for arthropod pests of tomato from a global perspective, encompassing all production types (field, protected, organic) - Includes chapters on integrated management of tomato pests and specific aspects of tomato pest management, including within protected structures and in organic production - Presents management systems that have been tested in the real-world by the authors of each chapter - Fully illustrated throughout with line drawings and color plates that illustrate key pest and beneficial arthropods associated with tomato production around the world
