Download or read book Thrips Biology and Management written by Bruce L. Parker and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thrips (fhysanoptera) are very small insects, widespread throughout the world with a preponderance of tropical species, many temperate ones, and even a few living in arctic regions. Of the approximately 5,000 species so far identified, only a few hundred are crop pests, causing serious damage or transmitting diseases to growing crops and harvestable produce in most countries. Their fringed wings confer a natural ability to disperse widely, blown by the wind. Their minute size and cryptic behavior make them difficult to detect either in the field or in fresh vegetation transported during international trade of vegetables, fruit and ornamental flowers. Many species have now spread from their original natural habitats and hosts to favorable new environments where they often reproduce rapidly to develop intense damaging infestations that are costly to control. Over the past decade there have been several spectacular examples of this. The western flower thrips has expanded its range from the North American continent to Europe, Australia and South Africa. Thrips palmi has spread from its presumed origin, the island of Sumatra, to the coast of Florida, and threatens to extend its distribution throughout North and South America. Pear thrips, a known orchard pest of Europe and the western United States and Canada has recently become a major defoliator of hardwood trees in Vermont and the neighboring states. Local outbreaks of other species are also becoming problems in field and glasshouse crops as the effectiveness of insecticides against them decline.

Download or read book Virus and Virus-like Diseases of Major Crops in Developing Countries written by Gad Loebenstein and published by Springer Science & Business Media. This book was released on 2013-12-18 with total page 831 pages. Available in PDF, EPUB and Kindle. Book excerpt: It appears that a comprehensive and up-to-date book on the impact of virus diseases on the major crops in developing countries is now much needed, especially as there have been rapid advances in the biological and molecular characterization and detection of the pathogens and possible approaches for their control. On the other hand, the economic losses caused by many of these diseases are tremendous and much of the accumulated knowledge to diminish the crop losses has not filtered through, or cannot be applied. This book is focused on the important crops. Each chapter on a specific crop will include inter alia, geographical distribution, the viruses - symptoms, damage, detection - a brief description of the viruses concerned, and present and future ways for their control. Experts from India, Nigeria, UK, USA, France, Germany, Peru, Japan, Australia, Netherlands, Venezuela, Kazakhstan and Israel (many of them from the International Research Institutions) have contributed chapters to this book.

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.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Tomato spotted wilt virus continues to be a serious problem on tobacco production in the southeast United States. The current control recommendation calls for acibenzolar-S-methyl, which is known by growers in North Carolina to have unacceptable phytotoxicity. In an attempt to reduce the amount of phytotoxicity while retaining similar levels of control as the current recommendation, on-farm tests were conducted in North Carolina to refine the application rate, timing and method of acibenzolar-S-methyl application, with or without an insecticide. The lowest disease incidence and highest phytotoxicity were recorded in treatments consisting of greenhouse drench applications of imidacloprid or thiamethoxam and acibenzolar-S-methyl, as compared to the untreated control. TSW severity and temporal progress results suggest that certain treatments delay the onset of symptoms. Furthermore, supplementary greenhouse experiments showed that timing the clipping relative to the timing of applications of the aforementioned chemicals had no effect on phytotoxicity. Both the order in which the chemicals were applied and applying the second chemical at varying times relative to the first had no consistent effect upon the phytotoxicity measured in the field. Overall, applying acibenzolar-S-methyl with an insecticide in the greenhouse provided the best control among the treatments tested. The temporal and spatial distribution of Tomato spotted wilt (TSW) was studied in a total of 25 naturally infested fields in 2006, 2007, and 2008. Sections within the fields were monitored that ranged in size from 76 x 11 meters to 137 x 10 meters. TSW incidence was measured on a weekly basis. TSW temporal progression data was fit to a logistic regression model with cumulative degree days and past TSW field history as explanatory variables. Analyses revealed that both variables are significant explanatory factors of the temporal progression of TSW on tobacco. Cooling degree-days were calculated with fo.
