Available in PDF, EPUB and Kindle. Book excerpt: Regenerating British Columbia's Forests will assist those responsible for planning reforestation projects to reach informed decisions and will challenge them to consider primarily the biological factors basic to reforestation success rather than short-term costs and production technology. Although its main audience is practising foresters and forestry students of British Columbia, the text will be of considerable interest to foresters in other parts of Canada, the United States, and Europe who manage reforestation.

Download or read book Aphids as Crop Pests 2nd Edition written by Helmut F van Emden and published by CABI. This book was released on 2017-08-23 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Aphids on the World s Herbaceous Plants and Shrubs 2 Volume Set written by R. L. Blackman and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 1460 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Aphids as Virus Vectors written by Kerry F. Harris and published by Elsevier. This book was released on 2014-05-10 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aphids as Virus Vectors focuses on aphids as vectors of plant viruses and the fundamentals of their relationship with virus and host. The mouthparts and feeding mechanism of aphids are discussed, along with aphid penetration of plant tissues and the transmission mechanisms of aphids as virus vectors. The intrinsic properties and taxonomy of aphid-borne viruses are also examined. Comprised of 22 chapters, this book begins with an overview of the importance of aphids as vectors, their biology, and the properties of the viruses they transmit. These introductory chapters prepare the reader for later ones on aphid-virus-plant interactions. The next section deals with transmission mechanisms, with emphasis on several novel alternatives to many of the traditionally held concepts of how aphids transmit viruses. Accessory factors in non-persistent virus transmission are considered. Subsequent chapters focus on technological advances in aphid-virus research, including the use of aphid cell culturing, radioisotope methodology, membrane feeding, and electrical measurement systems. The most promising frontiers in epidemiological and control-oriented research are discussed in the last two sections. This monograph will be a useful resource for researchers from such varied sciences as entomology, plant science, and virology, as well as for graduate students taking entomology and plant pathology courses on insects in relation to plant diseases.

This book was released on 1976-06-30 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of the particular topics in biological control programmes all over the world indicates an increased interest in the utilization of aphid parasites. Besides the so-called traditional biological control of introduced aphids, there appears a situation which could perhaps be called a renaissance of biocontrol, i. e. the utilization of biotic agents against insecticide-resistant populations of aphid pests. The rapid increase in the amount of information as well as the necessity of syntheti- cal papers are the well-known features in today's entomology. This requirement is much more topical in the groups where brief summarized information is needed for research workers in applied branches. The author has been well aware of all these difficulties and requirements owing to his own experience both in basic and applied research. Several years ago he decided to summarize our knowledge on the aphid parasites of the world by elaborating synthetical studies on the particular zoogeographical areas.These papers have been intended to represent annotated reviews of the parasite fauna, distribution, biologies and utilization in aphid pest management, with keys to genera and species, hos- parasite catalogue, and a list of references added. Naturally, these studies are only relatively updated, with respect to a certain deadline from which the research may be further continued. At present, the Far East Asian and the Mediterranean areas have been reviewed in this or at least in a similar manner.
