Le Docteur Paul Thuillier, chirurgien, n'a rien d'un tueur. Pourtant... Échappé d'un hôpital islandais, où il avait été placé en quarantaine après une grave épidémie virale, il affronte le froid et la neige, et se cache dans un refuge sur le plateau désertique de l'île. Aux abois, il assassine un ranger et masque son crime en accident. S'il n'obtient pas l'aide du Dr Samueldottir, sa seule connaissance sur l'île, il est condamné. Il contacte sa collègue qui, ignorant le drame, accepte de l'héberger. Il faut faire vite, l'hiver s'installe. Elle tombe sous le charme, Paul joue le jeu, mais ne songe qu'au stratagème qu'il met en place pour quitter l'île : un plan diabolique dessiné avec la précision d'un chirurgien.

The most important prerequisites imperative for survival of human kind food, fodder and fuel depends upon the performance of plants. Due to worldwide temperature inversions, the weather conditions have become completely unpredictable and hostile. Thus, there is a growing need of such plants which are better adapted to these adverse climatic conditions. A good understanding of the signaling mechanism within the plant system during these climatic conditions will certainly going to help in raising plants which are better suited for these adverse conditions. Stress Signaling in Plants: Genomics and Proteomics Perspective Volume 1 brings together both a Genomics and Proteomics approach to further our understanding in this direction. The volume expands on the current understanding from Bioinformatical approaches to develop the models, as well as proving the ideas up to field conditions. Further, the volume contains comprehensive knowledge of stress signalling useful for graduate students, researchers as well as scientists working in the area. The ten chapters written by international dignitaries give much weightage to this book.

Fusarium head blight (FHB) on small-grain cereals is one of the most devastating diseases. Several species can cause head blight, though Fusarium graminearum is the predominant pathogen in most regions. F. graminearum is one of the most intensively studied fungal plant pathogens. This book presents the current state of knowledge regarding mycological aspects that make wheat-Fusarium interaction, such as hyphal growth, morphogenesis in germinating spores, visualization of enzymatic hydrolysis, production of mycotoxins, inhibition of the hyphal growth by antagonist microorganisms, use of natural substances or by modification of the host resistance, as well as genetic analysis and expression of genes that regulate the infection. Fungal ecology and epidemiology will also be discussed. Just as the analysis of environmental requirements for the establishment of the disease, the use of forecasts of disease risk with meteorological base and integrated management and control. This book includes the study of disease in Latin America, therefore will be of interest to researchers who are working on the issue, as for those who are interested in knowing about the disease.

The theme of the book is highly relevant to the current emphasis on environment conservation, with focus on native biodiversity conservation in agro-ecosystems. The current impetus being given to organic farming and export oriented agri-hortculture in the country calls for access to relevant scientific knowledge base among the stakeholders. Research on biological pest control is more than a century old in India. Egg parasitoids, which are mainly tiny wasps, led by the family Trichogrammatidae, are the most widely utilized natural enemies for biological control globally. Over thirty countries are using these bioagents to protect over 10 million hectares of agricultural and forestry crops from many important insect pests. The book comprises 18 chapters, which are arranged in continuum, commencing with basic aspects of knowledge and ending in their utilization targets. The chapters cover broadly four areas: bio-diversity and natural occurrence of egg parasitoids, behaviour and adaptation of egg parasitoids, mass production and safe use of egg parasitoids and utilisation of egg parasitoids in different crop ecosystems. Some of the chapters cater to the needs of discipline-wise update on the current R&D scenario-like insect taxonomy, biotechnology, mass-production and quality control of the target organisms - egg-parasitoids, which are useful for laboratory scientists/researchers. There are also chapters devoted to knowledge status and scope for utilization of egg parasitoids in different target crops, which cater to requirements of field entomologists and extensionists for use in their tasks of guiding farmers/local guides. The book is different in approach, method, structure and content and ensures holistic coverage of the topic. The chapters are written by active and experienced workers in different crops and aspects and co-edited by four very experienced experts who have over three decades R&D experience in the subject. All the authors have uniformly focussed on comprehensive literature study and critical identification of knowledge gaps for future R&D, thus the book is novel in outlook, up-to-date in content and comprehensive in coverage of themes. This book will be useful for supplementary reading for MSc Agriculture and PhD Agriculture students, besides MSc/PhD research students in Zoology/Environmental Biology, who are specialising in Entomology. It would also serve as a very useful reference book for researchers worldwide, though focus is also there on Indian work. It addresses the special information needs of students and faculty, besides practitioners and extensionists in the Australasia and Africa regions and thus not limited to the R&D knowledge generated in developed countries. .

Effectiveness of biological management of diseases may depend on the nature of interactions between the pathogens and other organisms and the plants. Because of development of resistance in pathogens to fungicides and bactericides, selection of strains of biocontrol agents (BCAs) showing resistance to synthetic chemicals is essential to to restrict use of the chemicals. Microbial plant pathogens and the antagonists present in the soil and on the plant surfaces are influenced by the cultural practices such as ploughing, nutrients applied, date of planting and harvesting, plant spacing, irrigation and harvest operations. Crop sanitation is a simple and important practice to eliminate or reduce the pathogen inoculum. It is possible to reduce disease incidence and intensity by including appropriate rotational crops which are resistant/immune to the target pathogen. Intercropping has been shown to be effective in reducing the incidence of virus diseases. Application of physical and chemical techniques involving the use of heat, solarization and irradiation may reduce the pathogen population or weaken potential of pathogens present in seeds, plants and soil. Irradiation with UV-C has favorable effect on fruits and vegetables which exhibit resistance to postharvest pathogens. Seed treatment with UV-C reduces infection by seedborne pathogens too. Some of the fungal pathogens have been identified as mycoherbicides. Entomopathogenic fungi effective against important groups of insects functioning as vectors of viruses have been identified. Two types of formulations are made from microbial antagonists. Liquid formulations as flowable or aqueous suspensions in water, oils or emulsions are prepared. Dry formulation products are available as wettable powders, dusts or granules. The bioproducts are applied to soil, seeds, propagative plant materials, whole plants and harvested produce as protective or curative treatments. Biological disease management systems for agricultural and horticultural crops have been developed by integrating strategies with synergistic effects on each other. Efforts to develop integrated systems of disease management have been scarce. Methods of integrating management strategies for diseases affecting agricultural and horticultural crops and the achievement of high levels of disease control are discussed. Protocols for isolation/ identification and assessing the biocontrol activities of biotic and abiotic biocontrol agents provided in relevant chapters will be useful for researchers and teachers.
