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.

This book was released on 2009-01-01 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of how many books can it be said that their publication directly affected the personal wellbeing of every person on the earth? No doubt, many books have been written which have changed the outlook of millions, altered social institutions, and even deflected the course of history, but of very few can it be said that their contents concerned the very central core of the construction of that rare amongst rarest of human morphs – the scientist – whom the entire humanity owes virtually everything, from good living conditions including clothes, drinking water, food, hygiene and health to clean environment. This book is all about the virtues that make a scientist. It is certainly not an easy task to define a scientist but for the characteristic that he is maddeningly obsessed with the prospects of achieving his objective under the severest of personal and professional stumbling blocks! Beforehand, thus, he visualises the entire scenario of his undertakings without actually physically seeing & that is what makes him different from a man of ordinary mould: Wise haveth their eyes, in the head; Fools waketh through forest, & see no firewood! I hope that this book, unique in its approach and treatment on the subject, and written with a view to ignite the young minds to develop habits of perseverance and dedication, so that a stronger future of India could be constructed.

Available in PDF, EPUB and Kindle. Book excerpt: Vectors of Plant Pathogens is a collection of papers that discusses the interrelationship of plant pathogens with their vectors. This collection deals with the numerous vector groups associated with plant pathogens. One paper describes the biology, feeding behavior and distribution of aphids, leafhoppers, plant hoppers, mealy bugs, whiteflies, psyllids, membracids. Another paper addresses the virus transmission characteristics of the mealy bugs during preliminary fasting or feeding, acquisition access time, post-acquisition fasting or feeding, and the inoculation access time. Other papers also discuss the involvement of insects in transmitting bacterial and fungal pathogens; the authors list unresolved issues such as the role of insects in overwintering of bacterial pathogens or the association of the fungus with a particular vector. One author describes some suspected fungi transmission such as the pea stem necrosis virus, red clover necrotic mosaic virus, and the tomato bushy stunt virus. Another paper examines the fate of plant viruses in mite vectors and convectors particularly the viruses found in wheat, barley, or brome grass. Agriculturists, botanists, and researchers in the field of botany, conservation, and plant genealogy will find this book useful.

Available in PDF, EPUB and Kindle. Book excerpt: The dominance of insects amongst all living organisms on earth, coupled with infinite wealth of knowledge so important for our own existence, is a fundamental scientific fact which is yet to be widely acknowledged. This dominance means that in numbers of species beyond our comprehension these animals permeate diverse and essential natural processes in Earth's terrestrial, aerial and freshwater ecosystems, contributing to the function of the natural world as a self-sustaining biological system. Invariably insects are an integral and complex part of the terrestrial and freshwater ecosystems with which the future of humans is inextricably linked. Insects have ultimately achieved a formidable diversity. Generally, insects are beneficial organisms, however, many of them are important pests and/or vectors to a large number of parasites and other microbial pathogens to both human being, his associates and the plants. The burden caused by their infestation or infection run up to several million-zillion rupees annually. Therefore, knowledge about extreme biodiversity and ecological relationships of these animals is a practical necessity: in the man's own interest to sustain the species. Packed with original 25 original articles/reviews, this book on 'Entomology: Ecology and Biodiversity' offers an invaluable opportunity to comprehend more deeply about our most intimate allies - the insects! The book truly establishes a foundation in basic entomology through varied and diverse treatment to entomology, while focusing on specialized topics in insect ecology and biodiversity, forensic and medical entomology.

Download or read book Bioprospecting of Indigenous Bioresources of North-East India written by Jubilee Purkayastha and published by Springer. This book was released on 2016-08-16 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is a comprehensive information on the indigenous bioresources of North Eastern India with the scope of bioprospecting for discovery and commercialization of new sources and products and long-term ecological balance. The exploration, conservation and sustainable utilization of bioresources of world’s Megabiodiversity Hotspots are undeniable. North Eastern India is a recognised biodiversity hot spot where the evolutionary forces are at its optimum, making this region as centre of origin for many species. Although little bit exploratory studies have been conducted in this part of the globe but a scientific exploitation of the bioresources is almost lacking. Unscientific exploitation and overexploitation without proper knowledge of the bioresources may lead to imbalanced ecosystem of this mega diversity region. At the same time, very less exploration and exploitation will hamper biodiversity based development. Today, unscientific dramatic changes are underway in this region. Human activities are changing, degrading and destroying the bioresources in an unplanned manner. Scientific bioprospecting of the bioresources will boost the economy while ensuring conservation. This book offers comprehensive information about various levels of bioprospecting of the gene pool of this Indo-Burma Mega Biodiversity Hot Spot, the North East India, which is endowed with huge biodiversity potential for exploration and exploitation for the benefit of humankind. Also, this book highlights the less and merely explored part of the indigenous biodiversity of North East India with explanation towards their better sustainable exploitation for benefit of the people, economy and environment. The novelty of the book lies in expert coverage of the bioresources of this mega-diverse region including plants, microbes, insects etc. with provisions for their sustainable scientific utilization. This book portrays North East India as a melting pot of bioresources which are little explored and also those resources which are still to be explored. The book mainly highlights the bioprospecting approaches for North East Indian bioresources, and thus, it make itself a unique one in filling the knowledge gap that is there regarding the bioprospecting of the biodiversity of this special region on the earth. The book concludes by the ecotourism potential of this region. The target audiences for this book include biodiversity economists who are working on technology and bioresource management issues, and especially on biotechnology and biodiversity, development economists addressing the issues of bioresources in developing countries. These people may be in academia, in government, in non-governmental organizations and in private companies. The other target audiences group is policy scholars in government/public sectors who are interested in issues of biotechnology, IPRs, and biodiversity. In addition, scholars/experts in both development studies and resource management studies form another group of target audiences. Also, the book will be useful for the interaction between developed and developing nations regarding the issues of biodiversity and bioprospecting, as North Eastern India is the hub of Biodiversity.

Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of this book is to complement the hitherto largely descriptive works on the order Thysanoptera, by presenting thrips as living animals, stressing the behaviour of individuals and populations, their varied and complex relationships with plants, other animals and the physical components of their abundance in undisturbed and in cultivated habitats, and in cultivated economic importance as pests and beneficia. A considerable literature on thrips has accumulated over the last one hundred years. Unifortunately much of this information is fragmentary, scattered through obscure pamphlets, journales and accsesible only with difficulty.

Download or read book Research on Chrysomelidae, Volume 1 written by Pierre Jolivet and published by BRILL. This book was released on 2008-07-31 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are an estimated 40,000 species of chrysomelids, or leaf beetles, worldwide. These biologically interesting and often colorful organisms, such as the tortoise beetles, have a broad range of life histories and fascinating adaptations. For example, there are chrysomelids with shortened wings (brachypterous) and elytra (brachelytrous), other species are viviparous, and yet other leaf beetles have complicated anti predator-parasitoid defenses. Some species, such as corn rootworms (several species in the genus Diabrotica) constitute major agricultural crop pests. Research on Chrysomelidae 1 is a the first of an intended series of volumes on the Chrysomelidae edited by Jolivet, Santiago-Blay, and Schmitt.
