This work was begun to provide keys to the aquatic insect species known from Brazil. The original goal was to include all genera known from South America and all species from Brazil, but for most groups, the scope was expanded to encompass all species in South America, and, in some cases, to include terrestrial species of orders that include both terrestrial and aquatic taxa. In no case is a taxonomic revision of any group undertaken, although recommendations for such revisions are included where appropriate, and the probable synonymy of nominal species still treated as valid in the literature is noted. Two different approaches will be employed according to the taxon being treated. For phylogenetic groups encompassing overwhelmingly or exclusively aquatic species, such as the orders Plecoptera and Ephemeroptera or the families Dytiscidae and Culicidae, keys are provided to distinguish all genera and species known to occur in South America. An effort has been made to include every identifiable species so that the user of the key can determine with reasonable certainty whether or not his specimen belongs to a species that has already been described or whether it is one that is not yet known to science. Where feasible, complete keys will be prepared for groups containing both aquatic and terrestrial species that do not encompass an extraordinarily large number of species. This has already been done for the order Collembola.

The Encyclopedia of Entomology brings together the expertise of more than 450 distinguished entomologists from 40 countries to provide a worldwide overview of insects and their close relatives. Combining the basic science of an introductory text with accurate, comprehensive detail, the Encyclopedia is a reliable first source of reference for students and working professionals. Coverage includes insect classification, behavior, ecology, genetics and evolution, physiology, and management, and references to relevant literature. All the major arthropod groups are addressed, along with many important families and species. The Encyclopedia places special emphasis on insect relationships with people, medical entomology, biological control and insect pathology. This important work also presents biographical sketches of hundreds of entomologists who have made important contributions to the discipline since its origin. The new Second Edition is fully indexed, and includes more than 120 color plates. The four-volume Encyclopedia of Entomology is a handy desk-top reference for entomologists, and a valuable source of information for scientists and students in agronomy, botany, disease biology, ecology, evolutionary biology, forestry, genetics, horticulture, parasitology, toxicology, and zoology. It is also available as an easily accessible, fully searchable online reference.

The forests of West Africa are complex, beautiful and under continued threat of over exploitation. This monograph, in its second edition, remains the only comprehensive source of information on economically important forest insects in West Africa. Many pest insects discussed in this book have the potential to greatly alter the utilization of these valuable tropical forests. Several key pests such as mahogany shoot borer, odum gallfly and pests of endangered tree species like Pericopsis, are extensively discussed. This comprehensive treatise of insects includes information on the general forest cover types and insects of utilitarian value. The book will be a great value to foresters, forest entomologists, researchers, conservation biologists and others with a basic biological interest in West Africa forests.
