Floricultural crops all over the world are challenged by a number of insect and mite pests. The pest scenario is changing, and with climate change the instances of new pest incidences have become a more common problem. Like other crops, the intensive cultivation of commercial flowers has accentuated pest problems, as farmers tend to use more agricultural chemicals, which, in turn, increase the problems of pesticide resistance, pest resurgence, and residues leading to health hazards. This volume, Advances in Pest Management in Commercial Flowers, looks at the major challenges and improvements in this growing area today. It first provides an informative overview of worldwide pests of important commercial flowers. It explores a number of important issues in this area, such as the role of climate change on insect pests of commercial flowers and the synthetic chemicals and their possible harmful effects on the environment.

The idea that socialism could be established in a single country was adopted as an official doctrine by the Soviet Union in 1925, Stalin and Bukharin being the main formulators of the policy. Before this there had been much debate as to whether the only way to secure socialism would be as a result of socialist revolution on a much broader scale, across all Europe or wider still. This book traces the development of ideas about communist utopia from Plato onwards, paying particular attention to debates about universalist ideology versus the possibility for "socialism in one country". The book argues that although the prevailing view is that "socialism in one country" was a sharp break from a long tradition that tended to view socialism as only possible if universal, in fact the territorially confined socialist project had long roots, including in the writings of Marx and Engels.
The scientific understanding of arthropod phylogeny and evolution has changed significantly in recent decades. One of the most momentous alterations involved crustaceans, which are not a monophyletc group, but are part of a larger group along with insects: Pancrustacea. The old ideas surrounding crustacean evolution have served scientists well for many years; it is now time to turn toward new research by embracing the results derived from investigations conducted largely within this century. For example, new definitions have arisen from sources across several fields of study, and Frederick R. Schram and Stefan Koenemann have created a book that explores paleobiodiversity and the diversity of modern body plans. Developments within ontogenetic studies continue to generate remarkable insights into crustaceomorph evolution in regard to patterns of embryology and a revolution in the application of development genetics. Phylogeny techniques of analysis and new sources of data derived from molecular sequencing and genetic studies have forced scientists to consider new hypotheses concerning the interrelationships of all the pancrustaceans, both the crustaceomorphs and Hexapoda. Yet, some fossil groups still remain enigmatic (Thylacocephala). Despite this, research into fossils (even if incompletely understood) fills in gaps of our knowledge of paleobiodiversity, and it's useful for many things, including analyzing the origin and early evolution of Hexapoda. Evolution and Phylogeny of Pancrustacea demonstrates the use of multiple alternative hypotheses and other techniques through the well-executed presentation of diverse data sources involving Pancrustacea. Readers are left with clues to great mysteries, including the possible pathways of evolution within marine arthropods.
While silk derived from silkworm has been of economic importance for centuries, more recently silkworm has been found to have utility in biomedicine. This has attracted attention for expressing eukaryotic recombinant proteins, which require post-translational modifications. In 1985 Dr. Susumu Maeda demonstrated that silkworm larvae could produce a functional human-interferon. Since then various techniques have been developed to express recombinant proteins in silkworm. With the development of the Bombyx mori nucleopolyhedrovirus (BmNPV) bacmid system, which is capable of replicating in both Escherichia coli and Bombyx mori derived cell lines or silkworm, silkworm larvae or pupae have been used for the expression system for recombinant protein production. This method has the advantage of a bacmid, in that it can be easily prepared for sufficient bacmid DNA for subsequent expression in silkworm. It is potentially a big breakthrough in production of recombinant eukaryotic proteins and viruses, which will be a powerful tool in a new proteome era. This volume contributes to the advancement of our knowledge in the subject, for example gene expression systems and silkworm research, and focuses on silkworm biofactories for the recombinant protein production and commercial applications of proteins.
In a world all too familiar with environmental disasters, Horst Kornberger argues that the bee crisis is a more significant problem than deforestation, pollution and global warming put together, as it points to the causes behind all these. Global Hive is a rallying cry for a new understanding of world ecology. More than a study of bees, this book offers both an entirely new way of thinking about the bee crisis and its causes, and a way to use the crisis to explore wider social and ecological issues. Kornberger challenges the dominant scientific worldview that reduces everything to minute detail and fails to see the larger holistic picture. He argues that we urgently need to start thinking about ecology in a different way -- by developing a new science which draws on empathy and imagination -- if we want to mend our relationship with the natural world. From this perspective, the worldwide threat of the bee crisis becomes a starting point for global change. Global Hive is a thought-provoking treatise on what colony collapse teaches us about our society, our choices and how we can build a more sustainable world.
In Britain and Ireland there are about ten times more species of solitary bee than bumblebee and honeybee combined, yet the solitary bees tend to be ignored and we know much less about them. They are a fascinating, attractive and diverse group that can be found easily in a wide range of habitats, both urban and rural, and they are important as pollinators. Solitary bees provides an introduction to the natural history, ecology and conservation of solitary bees, together with an easy-to-use key to genera. Chapters cover: Diversity and recognition; Bee lives; Cuckoos in the nest; Bees and flowers; The conservation of solitary bees; Approaches to practical work; Keys to the genera of bees of the British Isles - Females and Males; and References and further reading.
This book recounts the habits of many interesting and unusual exceptions to the rule that insects are typically terrestrial forms of life. It examines the different ways that groups of species have developed modes of existence in or on the surface of water, and gives reasons why the gross morphology of insects is not favorable for life in or near bodies of water, such as wings that fail to function after coming into contact with water, rendering them useless.
The history of pathogens and vectors, unique symptoms of diseases and economic importance of important viral diseases have been dealt with in the introductory chapter of this book. While highlighting the role of arthropods, nematodes, and fungi; other agents of the spread of plant pathogens have also been included. Important aspects of insect vectors with direct bearing on transmission, i.e. vector identification, biology, feeding apparatus, and mechanism of spread including control of pathogens through vectors are covered comprehensively. As aphids and other hemipterous insects are major insect vectors, the book stresses on this order. There is a focus on the transmission of determinants under different categories of the transmission mechanism. The transmission determinant paradigm comprising coat protein and helper component has been expounded with recent cases. A brief description of new diseases at least one from each genus of plant viruses has been included in this compendium to elucidate the interaction of vector and virus. Phytoplasmal etiology of pathogens has been detailed separately on account of their importance. The transmission of plant viruses through insects with biting and chewing type of mouth parts has been discussed in detail as separate chapter. The latest research in the field of mites, nematodes, and fungi as vectors of plant viruses has been included. How the phytotoxemia is different from other crop disorders, has been critically explained with support from suitable and common examples of crop disorders. The book also highlights the effects of plant viruses on their vectors. An account of classification of plant viruses has also been given for better understanding of subject matter. Likewise, the information on the electron microscope along with its use has been included so as to define the procedure of examining sub-microscopic entities. The latest developments in the management of plant pathogens through vector management have been discussed with special reference to the use of biotechnology, crop protection, and plant resistance. The book will be of value to the teachers and to researchers. It will also be useful for extension workers in managing crop disorders. Students and researchers of entomology, plant pathology, plant protection and virology disciplines will obtain the latest in the field, through this book.
This book presents a 360-degree picture of the world of insects and explores how their existence affects our lives: the "good, bad, and ugly" aspects of their interactions with humankind. It provides a lucid introductory text for beginning undergraduate students in the life sciences, particularly those pursuing beginner courses in entomology, agriculture, and botany.
Harold Maxwell-Lefroy, the founder of Rentokil, was a maverick and a man of enormous drive and energy. From an early age he was fascinated with the insect world, and his thorough understanding of species' life cycles and habits, in its practical application, was to change the face of agriculture in several parts of the world. He was among the first really to apply the scientific method to dealing with insect pests, and the agriculture of the Caribbean and India still owes him an enormous debt. His book Indian Insect Pests is still in print, an invaluable resource to Indian agriculturalists. In the Caribbean he saved the sugar crop which had been ravaged by pests, and was then sent to India as the official entomologist. Here his energy and drive led to an education programme for Indian farmers that for the first time showed them that the devastating consequences of insect pests were avoidable, along with the destruction of livelihoods that had always been an occupational hazard. He became the first Professor of Entomology at Imperial College and developed patented anti-pest chemical treatments that led him to create Rentokil towards the end of his life - trademark rules barred him from calling it Entokil, as he had wanted to. He went on to save the roof of Westminster Hall from the death-watch-beetle infestation that would certainly have led to its collapse. But he was also an inveterate risk-taker, who drove without regard for his own safety, and applied the same principles to his scientific practice. He died at the young age of 48, overcome by the poisonous gases he was developing - without the proper breathing equipment. Rentokil is his most tangible legacy, but it all began with one man's single-minded dedication to the application of science.

This book is perhaps the first attempt to comprehensively project the uniqueness of molluscs, covering almost all aspects of reproduction and development from aplacophorans to vampyromorphic cephalopods. Molluscs are unique for the presence of protective external shell, defensive inking, geographic distribution from the depth of 9,050 m to an altitude of 4,300 m, gamete diversity, the use of nurse eggs and embryos to accelerate the first few mitotic divisions in embryos, the natural occurrence of androgenics in a couple of bivalves, viable induced tetraploids, gigantism induced by elevated ploidy, the complementary role played by mitochondrial genome in sex determination by nuclear genes and the uptake and accumulation of steroid hormone from surrounding waters. In molluscs, sexuality comprises of gonochorism (< 75 %) and hermaphroditism, which itself includes simultaneous (> 24%), protandry (< 1 %), Marian and serial. In them, the presence of shell affords iteroparity and relatively longer life span in prosobranchs and bivalves but its absence semelparity and short life span in opisthobranchs and cephalopods. Within semelparity, gonochorism facilitates faster growth and larger body size but hermaphroditism small body size. In them, sex is irrevocably determined at fertilization by a few unknown genes and is not amenable to any environmental influence. However, the sex determining mechanism is more a family trait in bivalves. Primary sex differentiation is also fixed and not amenable to environmental factor but secondary differentiation is labile, protracted and amenable to environmental factors. Both sex differentiation and reproductive cycle are accomplished and controlled solely by neurohormones. In these processes, the role of steroid hormones may be alien to molluscs.

Migration is a key process in the population dynamics of many insects, including some of the most damaging pests. Multidisciplinary research over the last three decades has produced a series of important new insights. This book reviews current understanding of the ecological, behavioural, physiological and genetic bases of insect migration. The first part describes migration systems in Europe, Asia, Africa, Australia and America, with an emphasis on the role of regional weather and climate. The second part considers how insects are adapted for migration; it covers aerodynamics and energetics, the integration of migration in insect life cycles, environmental and genetic regulation of migratory potential and the evolutionary implications of habitat heterogeneity and variability. The third part addresses the application of this knowledge to operational pest forecasting. The book concludes with a comprehensive overview of insect migration, written from an evolutionary perspective.
Nel 1925, Economo e Koskinas pubblicarono l'atlante piu accurato e completo sulla citoarchitettonica della corteccia cerebrale umana mai realizzato. Una sintesi del contenuto dell'atlante venne in seguito resa disponibile in tedesco e tradotta in italiano, inglese e francese. Il valore scientifico di quest'opera e divenuto piu significativo negli ultimi vent'anni con l'avvento delle tecniche di neuroimaging funzionale, le quali consentono persino di rilevare specifici focolai di attivazione nella corteccia cerebrale umana durante l'esecuzione di compiti cognitivi. Questa riedizione in italiano e stata ampliata rispetto all'originale con l'aggiunta della mappa dei solchi e dei giri del cervello. Inoltre, e stata inclusa la tabella delle corrispondenze tra le aree individuate da Economo e Koskinas e quelle descritte da Brodmann. Il volume sara di grande interesse per tutti coloro che desiderano approfondire la relazione tra la struttura del cervello e le sue funzioni; rappresentera inoltre un utile strumento di lavoro per i professionisti che utilizzano le neuroimmagini nella loro pratica quotidiana, quali neurofisiologi, neuropsicologi, neuroradiologi, neurologi e neurochirurghi.
This is the eighth volume of a ten-volume series on The Natural History of the Crustacea. The volume examines Evolution and Biogeography, and the first part of this volume is entirely dedicated to the explanation of the origins and successful establishment of the Crustacea in the oceans. In the second part of the book, the biogeography of the Crustacea is explored in order to infer how they conquered different biomes globally while adapting to a wide range of aquatic and terrestrial conditions. The final section examines more general patterns and processes, and the chapters offer useful insight into the future of crustaceans.
Many biological studies on insect management do not consider economics or fundamental economic principles. This book brings together economists and entomologists to explain the principles, successes, and challenges of effective insect management. It highlights the importance of economic analyses for decision making and the feasibility of such approaches, and examines integrated pest management (IPM) practices from around the world with an emphasis on agriculture and public health. The book begins by establishing an economic framework upon which to apply the principles of IPM. It continues to examine the entomological applications of economics, specifically, economic analyses concerning chemical, biological, and genetic control tactics as well as host plant resistance and the cost of sampling and is illustrated with case studies of economic-based IPM programs from around the world.
