Zustand: Hervorragend. Zustand: Hervorragend | Seiten: 324 | Sprache: Englisch | Produktart: Bücher | The earliest land-plants evolved around 450 million years ago from aquatic plants devoid of vascular systems. The diversification of flowering plants (angiosperms) during the Cretaceous period is associated with speciation in insects. Early insect herbivores were mandibulate, but the evolution of vascular plants led to the co-evolution of other forms of herbivory, such as leaf feeding, sap-sucking, leaf mining, tissue borer, gall forming and nectar-feeding. Plant defense against biotic stress is an adaptive evolution by plants to increase their fitness. Plants use a variety of strategies to defend against damage caused by herbivores. Plant defense mechanisms are either inbuilt or induced. Inbuilt mechanisms are always present within the plant, while induced defenses are produced or mobilized to the site where a plant is injured. Induced defense mechanisms include morphological, physiological changes and production of secondary metabolites.Host plant resistance (HPR) is one of the eco-friendly methods of pest management. It protects the crop by making it less suitable or tolerant to the pest. While books on theoretical aspects of HPR are available, an exclusive book on the practical aspects is lacking. There is a wide gap between the theory and the experimental procedures required for conducting studies on plant resistance for the post graduate students and young researchers. A dire need for a book on practical aspects was strongly felt. Initially a practical manual was prepared which eventually evolved into the present book. We hope this book provides information on major aspects of screening crop germplasm, sampling techniques, genetic and biochemical basis of HPR, behavioural studies on pheromone and plant volatiles, and some of the recent approaches in HPR. Further, the references provide the scientific articles and books as additional information to readers and workers alike.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Conogethes is a group of moths distributed in Austral-Asian region from India to New Guinea, the Solomon Islands and Australia.The moths are also found in Hawaii and Great Britain. Conogethes is mostly known for the economic impact of its larvae on agricultural crops. Substantial research has been undertaken in order to understand the biology of these harmful insects and to develop strategies to confine their impact. Research on chemical communication between males and females via sex pheromones is in progress.Recent research has also focused on the acoustic communication of Conogethes. The moths can feed on more than 200 plants in diversified habitats. The borer moths have become major pest on Horticultural , Agricultural,Avenue trees and forest trees. Its a pest of Quarantine importance as it has been found in Exportable commodities. The book contains 22 chapters from a dozen countries. The authors are from China, Vietnam, Australia, Sri Lanka, Malaysia, Norway etc. This is the first book on the pest globally where interesting insights are provided. This is one of the book of its kind on single pest dealing with almost all aspects of its biology and management on cultivated crops.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Insect science is fast changing as insects are evolving to a plethora of newer chemical molecules, climate change, management tactics and transformation of the landscapes. Through the International Conference, the editors have attempted to gather together newer aspects of Insect Sciences like Insect Taxonomy, DNA Barcoding, Physiology, Toxicology, Vectors and their Management, Molecular Biology, RNA interference in Pest Management, Semiochemicals and Pest Management using Host Plant Resistance and Biological Control appropriated especially for the developing world. Both basic and applied aspects of insect science have been included to stimulate comprehensive studies on insect science. The book not only deals with insect science but also environmental and ecological aspects in the hope that the book will be of immense use to students, researchers, extension workers, planners, administrators, farmers and other end users. The Chapters on diversified aspects of Insect Science are contributed by leading scientists for the coming 21 st century in which entomology is witnessing a dramatic advancement in management of pests through in-depth investigations. The dimensions of Insect Science covered in the book are pest management approaches that can be adopted worldwide with ascent on sustainability.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Arthropods are invertebrates that constitute over 90% of the animal kingdom,and theirbio-ecology iscloselylinked with global functioning and survival.Arthropods play an important role in maintaining the health of ecosystems, provide livelihoodsandnutrition to human communities, and areimportantindicators of environmental change. Yet the population trends of several arthropods species show themto be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth'sbiodiversity.Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago.Arthropods arecloselyassociated with living and non-living entitiesalike, making theecosystemservices they providecrucially important.In order to be effective, plansfor the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies forin situandex situconservation.This two-volume book focuseson capturing the essentials of arthropodinventories, biology, and conservation.Further, it seeks to identifythe mechanisms by which arthropodpopulations can be sustained in terrestrial and aquatic ecosystems, and by means of whichcertain problematic species be managed withoutproducing harmfulenvironmental side-effects.This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracingthediversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, itdescribes in detail the mechanisms of sustaining arthropod ecosystems, services and populations.It addresses thecontribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropodsfroma holisticperspectivebeforeaddressingconservation issues at large. This bookoffersa valuable resource forallzoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested intheconservation of biological resources.…
