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 Bioassays with Arthropods written by Jacqueline L. Robertson and published by CRC Press. This book was released on 2017-06-26 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Imagine a statistics book for bioassays written by a statistician. Next, imagine a statistics book for bioassays written for a layman. Bioassays with Arthropods, Third Edition offers the best of both worlds by translating the terse, precise language of the statistician into language used by the laboratory scientist. The book explains the statistical basis and analysis for each kind of quantal response bioassay in just the right amount of detail. The first two editions were a great reference for designing, conducting, and interpreting bioassays: this completely revised and updated third edition will also train the laboratory scientist to be an expert in estimation of dose response curves. New in the Third Edition: Introduces four new Windows and Apple-based computer programs (PoloJR, OptiDose, PoloMixture and PoloMulti) for the analyses of binary and multiple response analyses, respectively Replaces out-of-date GLIM examples with R program samples Includes a new chapter, Population Toxicology, and takes a systems approach to bioassays Expands the coverage of invasive species and quarantine statistics Building on the foundation set by the much-cited first two editions, the authors clearly delineate applications and ideas that are exceptionally challenging for those not already familiar with their use. They lead you through the methods with such ease and organization, that you suddenly find yourself readily able to apply concepts that you never thought you would understand.

Download or read book Onions and Allied Crops written by James L. Brewster and published by Taylor & Francis. This book was released on 2022-07-30 with total page 902 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1990, Onions and Allied Crops, is a comprehensive account of the edible allium, examined across three volumes. The collection examines the major economic and dietary importance of edible alliums in most countries, and brings together contributions from experts across multiple disciplines, including food scientists, economists, agriculturalists and biochemists. These books address selection and breeding of locally adapted cultivars and the development of cultural techniques, allowing for cultivation across the tropics, to the sub-arctic regions. As such the collection examines the allium as a major agricultural asset and the impact this has had on many economies. These volumes will be of use and of interest to food scientists, economists, agriculturalists and biochemists alike.
