| aphid life cycle diagram: Polyphagous Pests of Crops Omkar, 2021-01-04 Polyphagous pests are primarily agricultural pests that feed on economically important agricultural and horticultural crops of wide taxonomic diversity across the globe. They cause immense damage across different crop varieties owing to their generalist and voracious food habits. The advent of mono-crop culture in a huge area and the massive use of pesticides post green revolution have massively increased pest outbreaks all over the world. The Middle Eastern countries, African continent and even the Indian subcontinent is increasingly facing resurgences of polyphagus pests. This book compiles an inclusive account of polyphagous pests. It covers locusts, termites, aphids, whiteflies, mealybugs, scale insects, gram pod borer, fall armyworm, thrips, mites and rodents. The book discusses mode of spread, enormity of losses caused, mechanism of action, and also means to reduce the crop losses. It brings together a unique perspective for researchers to learn effective pest management practices across all crops. This book is a reference guide to researchers and also useful for academicians and students of entomology. |
| aphid life cycle diagram: Potato Biology and Biotechnology Dick Vreugdenhil, John Bradshaw, Christiane Gebhardt, Francine Govers, Mark A. Taylor, Donald K.L. MacKerron, Heather A. Ross, 2011-08-31 In the past 15-20 years major discoveries have been concluded on potato biology and biotechnology. Important new tools have been developed in the area of molecular genetics, and our understanding of potato physiology has been revolutionized due to amenability of the potato to genetic transformation. This technology has impacted our understanding of the molecular basis of plant-pathogen interaction and has also opened new opportunities for the use of the potato in a variety of non-food biotechnological purposes. This book covers the potato world market as it expands further into the new millennium. Authors stress the overriding need for stable yields to eliminate human hunger and poverty, while considering solutions to enhance global production and distribution. It comprehensively describes genetics and genetic resources, plant growth and development, response to the environment, tuber quality, pests and diseases, biotechnology and crop management. Potato Biology is the most valuable reference available for all professionals involved in the potato industry, plant biologists and agronomists. - Offers an understanding of the social, economic and market factors that influence production and distribution - Discusses developments and useful traits in transgenic biology and genetic engineering - The first reference entirely devoted to understanding new advances in potato biology and biotechnology |

| aphid life cycle diagram: Biology of Blood-Sucking Insects Mike Lehane, 2012-12-06 Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance. |

| aphid life cycle diagram: Insect-Plant Biology Louis M. Schoonhoven, Joop J. A. van Loon, Marcel Dicke, 2005-12 Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well. Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production. This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects.--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

| aphid life cycle diagram: Ecologically Based Pest Management National Research Council, Board on Agriculture, Committee on Pest and Pathogen Control Through Management of Biological Control Agents and Enhanced Cycles and Natural Processes, 1996-03-21 Widespread use of broad-spectrum chemical pesticides has revolutionized pest management. But there is growing concern about environmental contamination and human health risksâ€and continuing frustration over the ability of pests to develop resistance to pesticides. In Ecologically Based Pest Management, an expert committee advocates the sweeping adoption of ecologically based pest management (EBPM) that promotes both agricultural productivity and a balanced ecosystem. This volume offers a vision and strategies for creating a solid, comprehensive knowledge base to support a pest management system that incorporates ecosystem processes supplemented by a continuum of inputsâ€biological organisms, products, cultivars, and cultural controls. The result will be safe, profitable, and durable pest management strategies. The book evaluates the feasibility of EBPM and examines how best to move beyond optimal examples into the mainstream of agriculture. The committee stresses the need for information, identifies research priorities in the biological as well as socioeconomic realm, and suggests institutional structures for a multidisciplinary research effort. Ecologically Based Pest Management addresses risk assessment, risk management, and public oversight of EBPM. The volume also overviews the history of pest managementâ€from the use of sulfur compounds in 1000 B.C. to the emergence of transgenic technology. Ecologically Based Pest Management will be vitally important to the agrichemical industry; policymakers, regulators, and scientists in agriculture and forestry; biologists, researchers, and environmental advocates; and interested growers. |
