This book was released on 1980 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Deraeocoris Kirschbaum of western America north of Mexico was revised. Approximately 10,000 specimens from the Nearctic Region were examined. Taxonomic characters used by previous authors were reevaluated. In addition to the male parameres, the male vesica and the female posterior wall of the bursa copulatrix and sclerotized rings were used extensively in distinguishing species. Even though the species of this genus are predaceous, known host plants were used to assess the distribution of the species. Six species-groups are recognized based on comparative, quantitative and cladistic analysis of morphological and ecological characteristics. Forty-four species and one subspecies are known to occur in western North America. Five new species, Deraeocoris fraserensis, D. cochise, D. gilensis, D. knightonius, and D. schuhi are described. D. incertus variety picipes Knight is given species status. The following synonymies are proposed: D. rufusculus Knight = D. incertus Knight, D. pilosus Knight = D. fulvescens (Reuter), D. californicus Knight = D. cerachates Uhler, D. incertus variety carneolus Knight = D. picipes Knight. The remaining varieties named by H.H. Knight are recognized only as color forms of their respective nominal species. Until more specimens are secured and its range assessed accurately, D. barberi hesperus is retained as a subspecies of D. barberi, even though it shows some differences in the shape of the posterior wall of the bursa copulatrix. The male and female genitalia were found to be useful taxonomic characters for the genus. Intraspecific variation of the characters appeared to be significantly smaller when mature specimens are compared. Most species breed on one or several host plant species within a given type of habitat. The incertus and barberi groups breed exclusively on conifers. The remaining groups live on dictyledonous shrubs or trees. Many species are known to feed on aphids, chermids, psocids and coccids. Several species, including D. brevis and D. nebulosus, are of importance in the control of some orchard pests.

Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: This monumental reference work treats an entire worldwide order of insects. It summarizes, from both a biological and sytematic perspective, current knowledge on the Heteroptera, or true bugs, a group containing approximately 35,000 species, many of which are important to agriculture and public health. To introduce the reader to this group, Randall T. Schuh and James A. Slater offer chapters on the history of the study of the Heteroptera, research techniques, and sources of specimens. They also cover attributes of general biological interest, including habitats, habits, mimicry, and wing polymorphism; selected taxa of economic importance; and basic morphology.Presenting a current classification of the Heteroptera, the authors synthesize to the subfamily and sometimes tribal level the enormous, scattered literature, including diagnoses, keys, general natural history, a summary of distributions, and a listing of important faunistic works. In addition to a wealth of detailed illustrations, they provide a glossary to help the reader deal with the confusing terminology that has evolved over the years, as well as an extensive bibliography of more than 1350 entries.Meticulously prepared by two of the world's leading specialists, this major work will be the standard reference on the Heteroptera for many years to come.
