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.

This book was released on 2008-06-24 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subfamily Rileyinae (Hymenoptera: Eurytomidae) is redefined to contain 6 genera and 69 species for which keys are provided. Two morphological data sets, analyzed via maximum parsimony with PAUP*, yield hypotheses on the placement of Rileyinae within Eurytomidae and internal relationships of Rileyinae. Tables detailing host utilization for Eurytomidae (genera), Rileyinae (species), and confirmed/suspected plant associations for Rileyinae are included.
Download or read book Chalcidoidea of Iran written by Hassan Ghahari and published by CABI. This book was released on 2021-01-27 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The superfamily Chalcidoidea (Insecta, Hymenoptera) contains in excess of 26,000 described species worldwide, but with an estimated total diversity of more than 500,000 species the vast majority of species have yet to be discovered and described. Most chalcidoid species are parasitoids of hosts in at least 12 different insect orders, attacking the egg, larval or pupal stages, though phytophagy and other life cycles and hosts are known. Iran is the 18th largest country in the world and has a rich and diverse insect fauna, including Chalcidoidea. It is extremely interesting from a biogeographic point of view, and a paradise for an entomologist. This book summarizes the results of all prior research concerning species diversity of Iranian Chalcidoidea, including host records and distribution records by province in Iran as well as world distribution by country for 1,351 species of Chalcidoidea recorded from Iran through the end of 2019.

Download or read book Hymenoptera of the World written by Canada. Agriculture Canada. Research Branch and published by Canadian Government Publishing. 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.
Download or read book Advances in the systematics of Hymenoptera written by Norman F. Johnson and published by PenSoft Publishers LTD. This book was released on 2009-09-14 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This issue celebrates the 75th birthday ofÿ Dr. Lubom?r Masner, a source of knowledge, enthusiasm, and inspiration for systematic entomologists in all fields, but especially for students of Hymenoptera. His unflagging dedication to the study of the parasitoid wasps of the superfamilies Proctotrupoidea, Platygastroidea, and Ceraphronoidea has completely transformed our understanding of the richness and evolutionaryÿ history of these insects. His zeal and innovation in collecting have not only dramatically enhanced the basis for our understanding of hymenopteran diversity, but also contributed to the development of the Canadian National Collection of Insects into one of the premiere systematic entomology research institutions in the world. Twenty-six authors have contributed to this volume in 17 papers on the systematics of the families Braconidae, Ceraphronidae, Chalcididae, Eucharitidae, Eupelmidae, Eurytomidae, Figitidae, Mymaridae, Platygastridae, Vespidae, and Xiphydriidae. Six new genera and 33 new species are described, encompassing fossil material as well as species from the Neotropical, Afrotropical, Oriental, and Australasian regions. A short biography of Dr. Masner is accompanied by a bibliography of his scientific papers, a list of taxa he has described over 55 years of research, and a list of taxa named in his honor.

Download or read book Biogeography and Ecology of Southern Africa written by Marinus J.A. Werger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southern Africa is certainly not a naturally bounded area so that there are several possibilities for delineating it and concepts about its extent. Wellington* discussed the various possibilities for delineation and suggested that one line stands out more clearly and definitely as a physical boundary than any other, namely the South Equatorial Divide, the watershed between the ZaIre, Cuanza and Rufiji Rivers on the one hand and the Z ambezi, Cunene and Rovuma Rivers on the other. This South Equatorial Divide is indeed a major line of separation for some organisms and is also applicable in a certain geographical sense, though it does not possess the slightest significance for many other groups of organisms, ecosystems or geographical and physical features of Africa. The placing of the northern boundary of southern Africa differs in fact strongly per scientific dis cipline and is also influenced by practical considerations regarding the possibilities of scientific work as subordinate to certain political realities and historically grown traditions. This is illustrated, for example, in such works as the Flora of Southern Africa, where the northern boundary of the area is conceived as the northern and eastern political boundaries of South West Africa, South Africa and Swaziland. Botswana, traditionally included in the area covered by the Flora Zambesiaca, thus forms a large wedge in 'Southern Africa'.

Download or read book Parasitoids written by H. Charles J. Godfray and published by Princeton University Press. This book was released on 2019-12-31 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitoids lay their eggs on or in the bodies of other species of insect, and the parasitoid larvae develop by feeding on the host, causing its eventual death. Known for a long time to applied biologists for their importance in regulating the population densities of economic pests, parasitoids have recently proven to be valuable tools in testing many aspects of evolutionary theory. This book synthesizes the work of both schools of parasitoid biology and asks how a consideration of evolutionary biology can help us understand the behavior, ecology, and diversity of the approximately one to two million species of parasitoid found on earth. After a general introduction to parasitoid natural history and taxonomy, the first part of the book treats the different components of the reproductive strategy of parasitoids: searching for a host, host selection, clutch size, and the sex ratio. Subsequent chapters discuss pathogens and non-Mendelian genetic elements that affect sexual reproduction; evolutionary aspects of the physiological interactions between parasitoid and host; mating strategies; life history theory and community ecology. A special effort is made to discuss the theoretical background to the subject, but without the use of mathematics.
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.
Download or read book Biological Systematics written by Alessandro Minelli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: To some potential readers of this book the description of Biological System atics as an art may seem outdated and frankly wrong. For most people art is subjective and unconstrained by universal laws. While one picture, play or poem may be internally consistent comparison between different art products is meaningless except by way of the individual artists. On the other hand modern Biological Systematics - particularly phenetics and cladistics - is offered as objective and ultimately governed by universal laws. This implies that classifications of different groups of organisms, being the products of systematics, should be comparable irrespective of authorship. Throughout this book Minelli justifies his title by developing the theme that biological classifications are, in fact, very unequal in their expressions of the pattern and processes of the natural world. Specialists are imbibed with their own groups and tend to establish a consensus of what constitutes a species or a genus, or whether it should be desirable to recognize sub species, cultivars etc. Ornithologists freely recognize subspecies and rarely do bird genera contain more than 10 species. On the other hand some coleopterists and botanists work with genera with over 1500 species. This asymmetry may reflect a biological reality; it may express a working practicality, or simply an historical artefact (older erected genera often contain more species). Rarely are these phenomena questioned.
