Available in PDF, EPUB and Kindle. Book excerpt: All the economically important species of locusts and grasshoppers belong to Superfamily Acridoidea. They constitute an economically important group of Orthopterous pests infesting a number of cultivated and non-cultivated crops and are well known for their destructiveness all over the world. They are serious pests of agricultural crops, pastures and forests. They are also called short-horned grasshoppers in contrast to Ensifera (Tettigonoidea and Grylloidea) or long-horned grasshoppers which constitute one of the other suborder of Orthoptera. Suborder Caelifera is divided into four superfamilies viz. Acridoidea, Tridactyloidea, Tetrigoidea and Eumastacoidea. Acridoidea possess short antennae, usually shorter than the body, a short and stout ovipositor and their tarsi are three-segmented. The other superfamilies of Caelifera are easily recognizable at sight and are not frequently encountered. Superfamily Acridoidea has shown maximum diversity and divided into various families of which family Acrididae is widely distributed in India.The Superfamily Acridoidea constitute the largest and most diverse group amongst the Orthoptera. A very high degree of adaptive radiation in the feeding apparatus of this group of Orthoptera is indicative of their diverse feeding habits. The present proposal was aimed at studying large number of species of Acrididae which were collected from different regions of North India. The status of various characters used in the identification were judged on the basis of their consistency and variation to ascertain their importance in the group. An in-depth study helps in understanding the biodiversity and phylogeny of this group. The identification keys have been prepared to make identification easy. It is hoped that this book will bring the nomenclature of Indian Acrididae up to-date and will be useful to workers both in applied and basic research. The object of this book is to provide taxonomist, economic entomologist, agriculturist, ecologist and others with up to-date information on the valid genera and species along with their distribution in different parts of the country. The distribution of each species are given in the text. The authors have included their own observations on the distribution of Acrididae in North Indian regions which was ignored by earlier workers. The proposal has a great importance from the point of view of both applied and fundamental knowledge. Visualizing the economic importance of these pests the present book has been prepared.Work done and objectives achieved 1. Geographic area under North India have been extensively surveyed and Acridid samples have been collected.2. The collected specimens were studied in detail and described and illustrated taxonomically.3. Genitalic plates of the described taxa have been provided that complement the descriptions.4. Color photographs of the taxa have also been added to the descriptions that ease the identification of the same.5. A master chart depicting total specimens, their distribution, concentration areas, host plants etc. has been provided.6. Host range has been provided along with information on habitat, latitude and altitude..

Download or read book Biology Ecology and Systematics of Australian Scelio written by Paul Dangerfield and published by CSIRO PUBLISHING. This book was released on 2001-12-01 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic wasps of the genus Scelio play an important role in the regulation of orthopteran populations and are implicated in suppressing numbers of numerous pest locusts and grasshoppers. This landmark volume provides a full taxonomic treatment of the sixty species of Scelio found on the Australian continent and reviews in detail the biology and ecology and host relationships of Scelio on a worldwide basis. Taking an international perspective, the text outlines our current knowledge on topics such as host finding, population biology, and methods and techniques for collection and study in the field. The use of Scelio as biological control agents is discussed and comprehensive checklists document the recorded host relationships of each known species worldwide. There is a full taxonomic revision of all Australian species of Scelio, half of which are newly described. Each species description is complemented with high-quality line drawings, micrographs and distribution maps. In addition, an illustrated key to species enables easy identification of species by non-taxonomists. Biology, Ecology and Systematics of Australian Scelio provides wasp taxonomists, researchers of orthoptera and biological control workers with a basis for detailed studies elsewhere on this economically important group of insects.
Download or read book Indian Insects written by S Ramani and published by CRC Press. This book was released on 2019-10-16 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are the most interesting and diverse group of organisms on earth, many of which are useful as pollinators of crops and wild plants while others are useful as natural enemies keeping pestiferous insects in check. It is important to conserve these insects for our survival and for this the diversity of insect species inhabiting the different ecosystems of our country must be known. The cornerstone to studies of any kind of organismal diversity is their taxonomic identity. Even after over two and half centuries of studies, so little is known of the insect wealth of our country. It has contributions from taxonomists who have been studying Indian insects for long, this book offers up to date information on many important groups of Indian insects seeking to fill the lacuna of a long felt need for a comprehensive work on the taxonomy of Indian insects. Salient features: Provides an up-to-date taxonomy of major insect groups of India Presents identification keys with illustrations of several important groups of Indian insects Gives a new insight into why insects are so abundant Addresses fundamental questions in mechanoreception and cross kingdom interactions using insects as model systems Indian Insects: Diversity and Science is a festschrift to Professor C. A. Viraktamath, an insect taxonomist par excellence. It has been designed to cater to the needs of academicians, researchers and students who wish to identify insects collected from local environments and will be an invaluable aid for those working in the areas of systematics, ecology, behaviour, diversity and the conservation of insects.

The primary objective of the links between population-level processes this symposium was to integrate the current and system-level phenomena in a well-studied understanding of controls on ecosystem struc community. Unfortunately, some areas of cur ture and function with the approaches of popu rent research (e.g., nutrient cycling) are under lation biology. The annual grasslands are represented in this volume. For other topics eminently suitable for experimental and manip (particularly the role of invertebrate con sumers), the lack of data from the annual grass ulative studies of ecosystem processes.
