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.

Most people know of aphids as garden pests, infesting the soft green tissues of plants in vast numbers and killing them by sucking out the sap. Indeed, among the 4000 or so known species of aphids about 250 are pests, and in temperate regions several are economically important agricultural pests that damage crops directly during feeding or act as v

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.

Insects are a fascinatingly diverse and beautiful group of animals. They are found on all continents, in caves, underground, inside other insects, in rivers, lakes, puddles, and in our houses. To date, over a million insect species have been named. In this Very Short Introduction, Simon Leather explores insects' evolution, behaviour, and development, highlighting their pivotal role in supporting ecosystems across the planet. He considers the threats of environmental change, including climate change, to insects globally and the potentially catastrophic impact of insect population declines.

This second edition covers the evolution of aphids and their development in relation to specific plants, thoroughly revised and expanded since the first highly successful edition. Increasing knowledge of aphids has revealed that they are ideal organisms to use when studying many topical ecological issues.

The authors make this much-needed Naturalists' Handbook accessible by confining themselves to aphids living on broad-leaved trees. This has reduced the problems of identification to manageable proportions.
