DOWNLOAD EBOOKBoth volumes of Parasites and Pathogens of Insects provide in-depth coverage of the interface between insect parasites and pathogens and hosts, and explore the relationships between these partners. They emphasize biochemical and molecular interactions, basic biology, and the roles of hormones, receptors, and other cellular components in modulating interactions between host insects and attacking agents. These topics also are assessed in relation to biotechnology and biological control.In the short term, these volumes fill a void in current literature by emphasizing basic interactions at the biochemical and molecular levels. In the long term, these interactions may provide avenues for exploitation to enhance the rate of "beneficial" parasitism or to reduce the rates of disease transmission and infection of vertebrate hosts. - Presents the latest information on insect parasites and pathogens - Describes biochemical and molecular host-parasite and host-pathogen relationships - Covers mechanisms of insect pathogenicity and resistance - Provides exceptional breadth of coverage and authoritative reviews - Special topics - Transposable elements in insect pathogens - Co-evolution and gene transfer between hosts and invaders - Biological control

DOWNLOAD EBOOKNematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

DOWNLOAD EBOOKSpecies interactions, by changing phenotypic traits, can alter the outcome of subsequent interactions. Plant-mediated responses to herbivores have been extensively studied, but little is known about plant-mediated responses involving parasitic plants within a broader community context that also includes herbivores. Because parasitic plants are important components of many ecosystems and can shape community structure, it is important to understand how host-mediated interactions influence parasite preference and success. The goal of this thesis is to examine interactions between hosts, parasitic plants and herbivores mediated by chemical traits. We first examined the effects of dodder (Cuscuta sp.) parasitism on induced defenses in cranberry, and asked how cranberry chemistry affected dodder preference and performance. We found dodder preference for some cultivars, and dodder parasitism induced many changes in cranberry chemistry, which could influence other interactions with cranberry hosts. We next examined the effects of gypsy moth herbivory on cranberry chemistry, and how plant-mediated changes affected subsequent dodder preference. Herbivory delayed and reduced the number of dodder plants that attached to cranberry hosts. Herbivory also induced changes in cranberry phenolic acids and phytohormones, which could mediate defenses against dodder parasitism. We also assessed the effects of previous herbivory (by tobacco hornworm or mechanical) and previous dodder parasitism on subsequent dodder preference on tomato hosts. Previous attachment followed by removal of dodder slowed subsequent dodder attachment on tomato hosts, but prior herbivory did not affect subsequent dodder attachment. Lastly, we asked whether damage to host induced changes in the host, and if attached parasites assimilated host defenses in response to host damage. Damage to host plants induces higher jasmonic acid in both hosts and attached parasites, and herbivores fed on leaves from parasites attached to damaged hosts ate more than herbivores fed on leaves attached to undamaged parasites. In summary, these studies demonstrate that parasites can induce changes in host responses that can potentially shape other interactions with the same hosts. Similarly, both herbivores and host responses can influence parasite preference, which could alter behavior of herbivores and pollinators, shaping community dynamics.

DOWNLOAD EBOOKThis book analyzes for the first time how parasites shape the biology of social insects: the ants, wasps, bees, and termites. Paul Schmid-Hempel provides an overview of the existing knowledge of parasites in social insects. Current ideas are evaluated using a broad database, and the role of parasites for the evolution and maintenance of the social organization and biology of insects is carefully scrutinized. In addition, the author develops new insights, especially in his examination of the intricate relationships between parasites and their social hosts through the rigorous use of evolutionary and ecological concepts. Schmid-Hempel identifies gaps in our knowledge about parasites in social insects and uses models to develop new questions for future research. In addition, issues that are usually considered separately--such as division of labor, genetics, immunology, and epidemiology--are placed in a common framework to analyze two of the most successful adaptations of life: parasitism and sociality. This work will appeal not only to practitioners in the fields of behavioral ecology and sociobiology, but also to others interested in host-parasite relationships or in social organisms, such as apiculturists struggling to overcome the problems arising from mite infestations of honeybee colonies.

DOWNLOAD EBOOKIn spite of the fact that parasites represent more than half of all living species of plants and animals, their role in the evolution of life on earth has been substantially underestimated. Here, for the first time within an evolutionary and ecological framework, Peter Price integrates the biological attributes that characterize parasites ranging from such diverse groups as viruses, bacteria, protozoa, and fungi, to helminths, mites, insects, and parasitic flowering plants. Synthesizing systematics, ecology, behavioral biology, genetics, and biogeography, the author outlines the success of parasitism as a mode of life, the common features of the wide range of organisms that adopt such a way of life, the reasons for parasites' extraordinary potential for continued adaptive radiation, and their role in molding community structure by means of their impact on the evolution of host species. In demonstrating the importance of parasitic interactions for determining population patterns and geographical distributions, Dr. Price generates further discussion and suggests new areas for research.

DOWNLOAD EBOOKBlood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.
