Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Revision of the Aphelinin of North America: A Subfamily of Hymenopterous Parasites of the Family Chalcidid While the work of the Division Of Entomology is entirely carried on with the practical end in view, a certain amount Of work of a technical character IS constantly being done by different members of the force. The condition of our knowledge of North American insects at the present time is such that many forms which from time to time spring Into prominence as destructive species, or as connected with destruc t0 species, either as parasites or predatory enemies, are found to be new to science. They must be classified, described, and given names before they can be intelligently considered in economic publications. The practice which has prevailed to a limited extent of naming and describing new Species in practical bulletins and reports is one which has met with much disfavor among systematic workers. Isolated descriptions of new Species are in themselves sources of great annoy ance to all workers, and when these isolated descriptions are published elsewhere than in scientific journals or the proceedings of scientific societies the annoyance becomes intensified. The force of the Division of Entomology comprises several specialists who are doing descriptive work, and largely upon material accumulated in the course Of the reg ular divisional work. They are doing this work as a necessary supple ment to the purely economic output Of the Division, and to facilitate the investigations of the entomologists Of the State Agricultural Experiment Stations. It becomes important that the results of their labors should be published promptly, and as all available sources Of publication in this country, such as the Proceedings of the United States National Museum and the Transactions of the American Ento mological society, are chronically overcrowded with manuscripts, and are not published with any degree of promptitude, it is necessary that they should be issued by this Department.

Download or read book Hymenoptera Evolution Biodiversity and Biological Control written by Andrew Austin and published by CSIRO PUBLISHING. This book was released on 2000-10-26 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hymenoptera is one of the largest orders of terrestrial arthropods and comprises the sawflies, wasps, ants, bees and parasitic wasps. Hymenoptera: Evolution, Biodiversity and Biological Control examines the current state of all major areas of research for this important group of insects, including systematics, biological control, behaviour, ecology, and physiological interactions between parasitoids and hosts. The material in this volume originates from papers presented at the Fourth International Hymenoptera Conference held in Canberra, Australia in early 1999. This material has been extensively rewritten, refereed and edited; culminating in this authoritative and comprehensive collection of review and research papers on the Hymenoptera. The authors include many world-leading researchers in their respective fields, and this synthesis of their work will be a valuable resource for researchers and students of Hymenoptera, molecular systematics and insect ecology.
