Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.

Aphids represent one of the world's major insect pests, causing serious economic damage to a range of temperate and tropical crops. These range from grain crops and brassicas to potato, cotton, vegetable and fruit crops. This book provides a definitive reference volume on the biology of aphids, their pest status, and how to control them. It includes approximately 30 specially commissioned chapters from world experts, principally from Europe and North America. Topics covered range from host selection and feeding to movement and dispersal, and from insecticide resistance to chemical, cultural and biological control methods. There are also several case study chapters, on integrated pest management in specific crops.

Aphids are well-known as pests of agriculture, horticulture and forestry, but they are also one of the most biologically interesting groups of plant-feeding insects, and thus have attracted the attention of biologists in many research fields such as ecology, biodiversity, physiology, behaviour and genetics. Following the successful format of previous books on the world's aphids by the same authors, these two volumes provide a comprehensive species-by-species account of the aphids on the world's herbaceous plants and shrubs. They can be used not only as an identification guide and information source for entomologists and taxonomists throughout the world, but also as a unique database for studies of biodiversity and insect-plant relationships. In all, 3120 aphid species in 340 genera are covered, feeding on 2150 genera of host plants. Volume 1 features comprehensive host lists and keys to the aphids colonizing each plant genus. This information is supplemented in Volume 2 by a systematic account of all the aphid species, which provides information on their appearance in life, host range, geographical distribution and life cycles. There are 357 original line drawings, 252 photographs of slide-mounted specimens and 1000 references. Aphids on the World's Herbaceous Plants and Shrubs is the culmination of many years of work by two leading specialists and provides an essential research tool and standard reference work for entomologists in universities and research institutes throughout the world.

Biodiversity offers great potential for managing insect pests. Itprovides resistance genes and anti-insect compounds; a huge rangeof predatory and parasitic natural enemies of pests; and communityecology-level effects operating at the local and landscape scalesto check pest build-up. This book brings together world leaders intheoretical, methodological and applied aspects to provide acomprehensive treatment of this fast-moving field. Chapter authors from Europe, Asia, Africa, Australasia and theAmericas ensure a truly international scope. Topics range fromscientific principles, innovative research methods, ecologicaleconomics and effective communication to farmers, as well as casestudies of successful use of biodiversity-based pest managementsome of which extend over millions of hectares or are enshrined asgovernment policy. Written to be accessible to advanced undergraduates whilst alsostimulating the seasoned researcher, this work will help unlock thepower of biodiversity to deliver sustainable insect pestmanagement.

This is a textbook providing basic data about the crop pests and the damage they inflict throughout the tropics and sub-tropics. Each major pest is illustrated by either a line drawing or a photograph, and sometimes the damage can also be seen. A world distribution map is provided for each species. Control measures tend to be general rather than very specific. Most of the pests are insects and mites, but some nematodes, molluscs, birds and mammals are included.

Plant bugs—Miridae, the largest family of the Heteroptera, or true bugs—are globally important pests of crops such as alfalfa, apple, cocoa, cotton, sorghum, and tea. Some also are predators of crop pests and have been used successfully in biological control. Certain omnivorous plant bugs have been considered both harmful pests and beneficial natural enemies of pests on the same crop, depending on environmental conditions or the perspective of an observer.As high-yielding varieties that lack pest resistance are planted, mirids are likely to become even more important crop pests. They also threaten crops as insecticide resistance in the family increases, and as the spread of transgenic crops alters their populations. Predatory mirids are increasingly used as biocontrol agents, especially of greenhouse pests such as thrips and whiteflies. Mirids provide abundant opportunities for research on food webs, intraguild predation, and competition.Recent worldwide activity in mirid systematics and biology testifies to increasing interest in plant bugs. The first thorough review and synthesis of biological studies of mirids in more than 60 years, Biology of the Plant Bugs will serve as the basic reference for anyone studying these insects as pests, beneficial IPM predators, or as models for ecological research.
