California has one of the world's most diverse chrysidid wasp faunas. These are large, brightly metallic-colored parasitoids of sphecoid wasps and bees. This study reviews the species and genera of Chrysididae in California, maps their overall distributions, and gives keys to California genera and species. In addition, three species described by Linsenmaier in 1994 are synonymized.

Beewolves are a major group of solitary, ground-nesting wasps belonging to the genus Philanthus of the family Sphecidae. (The common name beewolf derives from the females' practice of preying upon bees to obtain food for their young.) This book brings together information on the biology of more than two-thirds of the 34 North American species, including much previously unpublished data, it is the first book on these wasps to provide extensive material on the behavior of both males and females.

Offering a complete accounting of the insects of North America, this handbook is an up-dated edition of the first handbook ever compiled in the history of American entomology. By using American Insects, A Handbook of the Insects of America North of Mexico, Second Edition, readers can quickly determine the taxonomic position of any species, genus, or higher taxon of insect known to occur in America and Canada. Every order, family, and genus is conveniently numbered and indexed, making this volume the only complete single source for all of the names of orders, families, and genera currently available. This book fills the need for an accurate way to identify, with the several hundred drawings and photos, the common insects of all orders. Now there is a tool available to those working without a major collection and library; and those who would like to have a general knowledge of insect life without becoming overwhelmed by the vast number of minute insect species. This usable guide provides sizes, shapes, color patterns and salient features of some species of each major family by pointing out those groups most likely to be encountered, including all North America pests. What's New in this Edition? Researchers in many orders use the results of cladistics, a new tool for determining the relationship of orders, families, genera, and species of organisms, including plants as well as animals Specialists have provided lengthy lists of generic changes Many of the identification keys have been revised by adding more illustrations and making sure all description terms are in the Glossary The bibliographies of each Order section have been updated to include all important works that have appeared since the original edition

Papp's superbly illustrated book will be a great help for pest management professionals, food plant and pharmaceutical laboratory quality control, libraries, entomology classes, and insect trappers everywhere. Foreword by George Okumura. Includes 2,850 scientically accurate insect illustrations. Species descriptive text accompanies each illustration.

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.

Report provides information on distribution, abundance, and health of birds, mammals, reptiles and amphibians, fishes, invertebrates, plants, terrestrial ecosystems, aquatic ecosystems, coastal and marine ecosystems, riparian ecosystems, the Great Plains, Interior West, Alaska, and Hawaii. It also discusses special issues: global climate change, human influences, non-native species, and habitat assessments.
