Download or read book Lepidopterorum Catalogus written by Poole and published by CRC Press. This book was released on 1989-01-01 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The noctuidae of the world, a family with numerous important agricultural pests, comprises about a third of the entire order Lepidoptera. This new three-volume set is the first complete catalog for the world. About 38,000 named species (including known synonyms) are listed alphabetically under each genus name in over 1,000 pages of text. Genera area also listed alphabetically, but subfamily affiliations are noted for each of the valid names to enable users to segregate genera by subfamily. Valid names are noted in boldface. Synonyms are listed for each genus and species; the species synonyms are also listed alphabetically among the valid names, thus enabling users to make two kinds of searches in the text as well as in the index. The catalog provides citation data on all described names (other than infraspecific names), with references cited in the compete bibliography at the end. Reference is also made to more important papers on the biology, larvae, host plants, and illustrations for each species, again with full titles noted in the bibliography. The main host plants for each species, where known, are listed under each. Details of holotypes, where known, are also noted. The bibliography has entries for approximately 4,400 papers.
Download or read book Ecological and Economic Entomology written by Brian E. Freeman and published by CABI. This book was released on 2020-11-11 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological and Economic Entomology is a comprehensive advanced text covering all aspects of the role of insects in natural ecosystems and their impacts on human activity. The book is divided into two sections. The first section begins with an outline of the structure, classification and importance of insects, followed by the geographical aspects of plant distribution and the complex defences plants marshal against herbivorous insects. Insect pests affecting plant roots, stem, leaf, and reproductive systems are covered in a comprehensive review. This section also covers insects that are important in medical and veterinary science, paying particular attention to those that transmit pathogens. The section concludes with the beneficial aspects of insects, especially their use in biological control, but also as soil formers and their importance in forensic science.
Download or read book Beneficial Insects written by David V. Alford and published by CRC Press. This book was released on 2019-04-23 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are key components of life on our planet, and their presence is essential for maintaining balanced terrestrial ecosystems. Without insects humans would struggle to survive, and on a world scale food production would be severely compromised. Many plants and animals depend directly or indirectly on insects for their very survival, and this is particularly so in the case of insectivorous birds and other such creatures. The beneficial role of insects is often overlooked or misunderstood, and in farming circles their very presence on crops is often seen to be unwelcome. In reality, however, many insects are genuinely beneficial, as in the case of parasitic and predacious species. The use of chemical pesticides to control crop pests is becoming more tightly regulated and environmentally undesirable, and low-input farming, in which natural enemies of pests are encouraged to survive or increase, is becoming far more prevalent. Accordingly, Integrated Pest Management (IPM) and Integrated Pest Management (ICM) strategies are increasingly being developed, advocated and adopted. Features: Highlights information on many groups of insects and mites that act as natural enemies or biological control agents of phytophagous insects and mites, including plant pests. Profusely illustrated with high-quality colour photographs. Focuses mainly on insects and mites as natural enemies of plant pests, including parasitic and predacious species that have been accidentally or deliberately introduced in classical biological control programmes. Reviews the role of phytophagous European insects and mites in controlling or managing European plants that have become invasive weeds in other parts of the world, notably North America, Australia and New Zealand.

This book was released on 2019-07-22 with total page 980 pages. Available in PDF, EPUB and Kindle. Book excerpt: A primary aim of this catalog is to offer an accounting for each species as originally proposed and for the first usage only of all its name combinations (including valid names, synonymies, and misspellings) that have been published for our area. We follow the policy outlined by the 1985 Code of Zoological Nomenclature for nonmenclatorial proposes that a dissertation for an advanced educational degree is not published unless it satisfies the criteria present in Articles 8 and 9.
Download or read book Pheromone Communication in Moths written by Jeremy D. Allison and published by Univ of California Press. This book was released on 2016-10-25 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Common among moths is a mate-finding system in which females emit a pheromone that induces males to fly upwind along the pheromone plume. Since the chemical pheromone of the domesticated silk moth was identified in 1959, a steady increase in the number of moth species whose pheromone attractants have been identified now results in a rich base for review and synthesis. Ê Pheromone Communication in Moths summarizes moth pheromone biology, covering the chemical structures used by the various lineages, signal production and perception, the genetic control of moth pheromone traits, interactions of pheromones with host-plant volatiles, pheromone dispersal and orientation, male pheromones and courtship, and the evolutionary forces that have likely shaped pheromone signals and their role in sexual selection. Also included are chapters on practical applications in the control and monitoring of pest species as well as case studies that address pheromone systems in a number of species and groups of closely allied species. ÊÊ Pheromone Communication in Moths is an invaluable resource for entomologists, chemical ecologists, pest-management scientists, and professionals who study pheromone communication and pest management.
Download or read book Grasshoppers and Grassland Health written by Jeffrey A. Lockwood and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acridids (grasshoppers and locusts) can range from being rare curiosities to abundant menaces. Some are threatened with extinction and become subjects of intensive conservation efforts, while others are devastating pests and become the objects of massive control programmes. Even within a species, there are times when the animal is so abundant that its crushed masses cause the wheels of trains to skid (the Rocky Mountain grasshopper, Melanoplus spretus Walsh in western North America in the 1860s and I 870s), while at other times the animal is alarmingly scarce (the Rocky Mountain grasshopper went extinct in the early 1900s). Why are there these extremes in one insect family, and even in a single species? The NATO workshop examined this paradox and its implications for Environmental Security, which must address both the elements of land use (agricultural production and pest management) and conservation of biodiversity. The reconciliation of these objectives clearly demands a critical assessment of current knowledge and policies, identification of future research, and close working relationships among scientists. Insects can present two clear faces, as well as the intervening gradation. These extremes require us to respond in two ways: conservation of scarce species and suppression of abundant (harmful) species. But perhaps most important, these opposite poles also provide the opportunity for an exchange of information and insight.

This book was released on 2010-09-17 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stephen L. Wood (1924?2009) was the leading authority of bark and pinhole borer beetle systematics (Scolytinae and Platypodinae) in the latter half of the 20th century. He published over 100 taxonomic papers including monographs and a worldwide catalog. His research advanced the understanding of Scolytinae and Platypodinaeÿ diversity and influenced several generations of bark beetle systematists. This Festschrift honors Dr. Wood?s 60 years of Scolytinae and Platypodinae systematic research. The 20 contributing authors represent worldwide taxonomic expertise that report on a range of topics from biology to phylogeny. These studies concern species from all major faunal regions. Twenty-three new taxa are described and five patronymics are named. Most taxonomic treatments include identification keys. A brief biography accompanied by a list of Dr. Wood?s publications is included.

Download or read book Parasites in Social Insects written by Paul Schmid-Hempel and published by Princeton University Press. This book was released on 2019-12-31 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes for the first time how parasites shape the biology of social insects: the ants, wasps, bees, and termites. Paul Schmid-Hempel provides an overview of the existing knowledge of parasites in social insects. Current ideas are evaluated using a broad database, and the role of parasites for the evolution and maintenance of the social organization and biology of insects is carefully scrutinized. In addition, the author develops new insights, especially in his examination of the intricate relationships between parasites and their social hosts through the rigorous use of evolutionary and ecological concepts. Schmid-Hempel identifies gaps in our knowledge about parasites in social insects and uses models to develop new questions for future research. In addition, issues that are usually considered separately--such as division of labor, genetics, immunology, and epidemiology--are placed in a common framework to analyze two of the most successful adaptations of life: parasitism and sociality. This work will appeal not only to practitioners in the fields of behavioral ecology and sociobiology, but also to others interested in host-parasite relationships or in social organisms, such as apiculturists struggling to overcome the problems arising from mite infestations of honeybee colonies.

Available in PDF, EPUB and Kindle. Book excerpt: This book considers some of the potential influences on individuals and populations (e.g. environmental stresses, parasites, cannibalism, dispersal limitations), the 'cunning tricks' used by aquatic insects to overcome challenges (e.g. polarization vision, life-history strategies, osmoregulation, cold hardiness) and the consequences of those challenges at different levels of organization (e.g. distribution patterns, population structure, population genetics, evolution).
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.
