Thrips Biology and Management (Hardcover, 1995 ed.): Bruce L. Parker, Margaret Skinner, Trevor Lewis Thrips Biology and Management (Hardcover, 1995 ed.)

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.

Thrips as Crop Pests (Hardcover): Trevor Lewis Thrips as Crop Pests (Hardcover)
Trevor Lewis
R5,416 Discovery Miles 54 160 Ships in 12 - 17 working days

Thrips have recently surged to prominence as insect pests of field, plantation and glasshouse crops in many countries, associated with increased international trade in fresh vegetables, fruit, flowers and plant propagation material. They can cause direct feeding damage to the aerial parts of plants, resulting in yield loss and spoilage, and some are vectors of destructive plant viruses. Their minute size and secretive habits make them particularly difficult to detect and control. This book, containing contributions from several world authorities from Europe, the USA and Asia, is the most comprehensive treatise on thrips as crop pests ever to be published. It brings together a vast amount of modern work set against a wealth of background knowledge, covering basic biology, ecology, applied science and pest control. The result is a book indispensable for agricultural advisers and growers concerned with thrips pests, and a unique reference source and stimulus for research entomologists studying these intriguing insects.

Integrating Cost as an Independent Variable Analysis with Evolutionary Acquisition - A Multiattribute Design Evaluation... Integrating Cost as an Independent Variable Analysis with Evolutionary Acquisition - A Multiattribute Design Evaluation Approach (Paperback)

Guidance from the Under Secretary of Defense for Acquisition, Technology, and Logistics USD (ATL) requires 100 percent of defense programs to incorporate cost as an independent variable (CAIV) and evolutionary acquisition (EA) plans within their management baselines. Historically, these two concepts have been implemented independent of one another. In reality, CAIV and EA are tightly coupled. Integration of these two initiatives enables warfighters and developers to better allocate constrained resources, respond to fluctuations in program funding, and plan for future development activities. This research creates a decision tool to assist the DoD acquisition community in satisfying the intent of the USD (ATL) guidance. Using multiattribute design evaluation techniques, a core CAIV model is formulated. Next, the core model is expanded to incorporate the dominant features of EA. The expanded model seeks to optimize overall utility across a horizon of multiple development increments. Additionally, technical risk factors are integrated to discount the realized level of attainment for design attributes.
