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 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 Ecology and Behaviour of the Ladybird Beetles Coccinellidae written by Ivo Hodek and published by John Wiley & Sons. This book was released on 2012-05-21 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ladybirds are probably the best known predators of aphids and coccids in the world, though this greatly underestimates the diversity of their biology. Maximising their impact on their prey is an important element in modern conservation biological control of indigenous natural enemies in contrast to the classical approach of releasing alien species. Ivo Hodek is one of the most internationally respected experts on coccinellids who has researched these insects for his entire career. He has now brought together 14 scientists of international standing to author 12 chapters, making this book the definitive treatment of coccinellid biology and ecology. This volume covers the rapid scientific developments of recent years in the understanding of coccinellid phylogeny, the semiochemicals influencing their behaviour and of molecular genetics. Recent insights in relation to intraguild predation and the assessment of the predatory impact of coccinellids are also covered. Other special features of the volume are the extensive references covering the literature from both East and West and a taxonomic glossary of the up-to-date nomenclature for species of coccinellids as well as of other organisms mentioned in the text. While aimed at researchers, university teachers and agricultural entomologists, the book is readable and appropriate for others who just have a liking for these interesting and attractive insects.
Download or read book Field Crop Arthropod Pests of Economic Importance written by Peter A. Edde and published by Academic Press. This book was released on 2021-08-21 with total page 1004 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field Crop Arthropod Pests of Economic Importance presents detailed descriptions of the biology and ecology of important arthropod pest of selected global field crops. Standard management options for insect pest control on crops include biological, non-chemical, and chemical approaches. However, because agricultural crops face a wide range of insect pests throughout the year, it can prove difficult to find a simple solution to insect pest control in many, if not most, cropping systems. A whole-farm or integrated pest management approach combines cultural, natural, and chemical controls to maintain insect pest populations below levels that cause economic damage to the crop. This practice requires accurate species identification and thorough knowledge of the biology and ecology of the target organism. Integration and effective use of various control components is often enhanced when the target organism is correctly identified, and its biology and ecology are known. This book provides a key resource toward that identification and understanding. Students and professionals in agronomy, insect detection and survey, and economic entomology will find the book a valuable learning aid and resource tool. - Includes insect synonyms, common names, and geographic distribution - Provides information on natural enemies - Is thoroughly referenced for future research

Download or read book Arthropod Diversity and Conservation in the Tropics and Sub tropics written by Akshay Kumar Chakravarthy and published by Springer. This book was released on 2016-11-23 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth’s biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation.Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.
