This book was released on 1993 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is the result of a course on identification of Hymenoptera given three times since 1985 at the Centre for Land and Biological Resources Research. The considerable interest in these courses indicated the need for a comprehensive identification guide to all extant families of Hymenoptera. The main emphasis is on family identification using the keys, which are complemented by family sketches. The sketches include a taxonomic diagnosis to supplement the keys, a summary of the biology, the size and distribution, and important literature references.

Download or read book Hymenoptera and Biodiversity written by John LaSalle and published by Oxford University Press, USA. This book was released on 1993 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing attention has been focused on biodiversity in recent years, based on a number of arguments to justify the conservation of the world's flora and fauna. Such arguments may be economic - that species may have potential for food or medicine - or ecological - that the extinction of any species affects the overall ecological balance. Little attention, however, has been focused on which groups have the greatest impact on maintaining diversity. Hymenoptera is one of these groups. It not only forms a major component of diversity itself, but is vital in sustaining diversity in other groups. Hymenoptera species (bees, wasps, ants and sawflies) are major plant pollinators, seed dispersers and parasitoids and predators of other arthropods (and hence important in biological control). This volume therefore tackles an important subject and concentrates on three key issues: how species of Hymenoptera affect diversity in other organisms; whether Hymenoptera is a group prone to extinction; and the consequences if Hymenoptera species are differentially removed from terrestrial ecosystems. The book is essential reading for entomologists and those concerned with biodiversity and conservation.

Download or read book Biocontrol Potential and its Exploitation in Sustainable Agriculture written by Rajeev K. Upadhyay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant based biotechnology has come to represent a means of mitigating the problems of global food security in the twenty-first century. Products and processes in agriculture are increasingly becoming linked to science and cutting edge technology, to enable the engineering of what are in effect, designer plants. One of the most successful , non-chemical approaches to pest management and disease control is biological control, which seeks a solution in terms of using living organisms to regulate the incidence of pests and pathogens, providing a natural control' while still maintaining the biological balance with the ecosystem. This volume, (the first of two), addresses the different types of biocontrol for different pests, namely, crop diseases, weeds and nematodes, and details the biology of both the pest and its enemies, which is vital for efficient use of biological control. The book has numerous contributors who are authorities in their fields, and would be an asset to those who have interest in sustainable agriculture and crop productivity.
