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 CRC Handbook of Viruses Infecting Legumes written by John R. Edwardson and published by CRC Press. This book was released on 1991-09-11 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: This interesting handbook discusses 145 plant viruses in 27 groups and 31 unclassified viruses in naturally infected legumes. The viruses were observed in field infections of 281 species in 64 genera of the Leguminosae. The book presents information regarding resistance sources and resistance-breeding, vectors, seed transmission, and host ranges. Measurements of virus properties are organized in tabular form for particle dimensions, serological relationships, nucleic acid percentages, sedimentation coefficients of particles and nucleic acids, molecular weights of nucleic acids and coat proteins, optical density, and buoyant density. Handbook of Viruses Infecting Legumes is unique in that it relates inclusion cytology to plant virus detection, identification, and classification. Light and electron micrographs illustrate morphology, location, and staining reactions of inclusions. Of the 27 groups that contain viruses infecting legumes in nature, inclusions are diagnostic at the group level in 15 of these groups. Plant breeders, diagnosticians, plant virologists, and students of plant virology will find this an indispensable guide to legume viruses.
