Download or read book Annotated Keys to the Genera of Nearctic Chalcidoidea Hymenoptera written by Gary A. P. Gibson and published by NRC Research Press. This book was released on 1997 with total page 814 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication presents illustrated keys to the 19 families and 706 described genera of Chalcidoidea known to occur in the Nearctic region (minimally America north of Mexico, but also including those areas of Mexico generally considered as having a Nearctic insect fauna). The first three chapters provide an introduction to this superfamily of wasps, most of whose members are parasites of other insects; a review of chalcidoid morphology as related to terms used in the keys & diagnoses; and an overview of the superfamily, including a 41 couplet key to families. Each of the remaining 19 chapters reviews one family & includes sections on recognition, systematics & relationships, biology, literature, an annotated key to the Nearctic genera, and for larger families an index to genera based on couplet number. Over 1,800 line drawings & electron micrographs illustrate the keys. Annotations include references to existing keys to species, estimated number of species, and known distribution & host range in the region.

Download or read book Revision of the European species of Omphale Haliday Hymenoptera Chalcidoidea Eulophidae written by Christer Hansson and published by PenSoft Publishers LTD. This book was released on 2012-10-25 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European species of Omphale are revised, including 37 species, of which 11 are new. All species are described, thoroughly illustrated, and included in gender-specific identification keys. Two new morphological character-sets are introduced for the classification, male genitalia and wing interference patterns (WIPs). Both sets are used to identify species, and the former is also useful for classification of species-groups. Hosts are known for 14 species and all are primary endoparasitoids of immature stages of gall-midges (Diptera: Cecidomyiidae). Host preferences are unique for each species, suggesting host specialization as a driving force for speciation. Several of the species are known only from females or have a strong female-biased sex-ratio, indicating thelytokous parthenogenesis. Distributional data point to a pan-European distribution for most species. New synonyms and combinations affect the nomenclature in subfamily Entedoninae.

Download or read book Parasitoid Wasps of South East Asia written by Buntika A. Butcher and published by CABI. This book was released on 2023-12-22 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitoid wasps are cosmopolitan, numerous and enormously diverse with probably one million or more species worldwide, most of which occur in the moist tropics. Their ecological importance is enormous although perhaps most evident in their major roles in the control of insect pest populations. In natural ecosystems they are integral in regulating populations of a vast number of insects, and therefore are key players in terrestrial food webs. Knowledge of their biology is still very poor because the current state of taxonomy is still in its infancy in most parts of the world.In this book, we provide an overview of the more than 30 families of parasitoid wasps that occur in the 11 countries in South East Asia. Particular emphasis is given to those most commonly encountered and reared, as well as to those used in biological control programmes. Outlines of the morphology, biology, ecology and behaviour of each family, as well as of various important subfamilies are presented. The current state of taxonomy in the region is summarised. Other chapters cover basic biology, behaviour, morphological terminology, phylogeny and methods of specimen collecting, preparation and rearing with particular relevance to the tropics. Modern molecular approaches to speeding taxonomic description of hyperdiverse taxa are considered in depth. All groups are illustrated with colour photographs. This book will be of value to professional entomologists, academics, entomology students and the growing body of amateur entomologists and insect photographers.

This book was released on 1993 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is the result of a course on identification of Hymenoptera given three times since 1985 at the Centre for Land and Biological Resources Research. The considerable interest in these courses indicated the need for a comprehensive identification guide to all extant families of Hymenoptera. The main emphasis is on family identification using the keys, which are complemented by family sketches. The sketches include a taxonomic diagnosis to supplement the keys, a summary of the biology, the size and distribution, and important literature references.
