Book Description
About 100 years ago, it was dicovered that insects transmit grave, mainly tropical diseases - very much to the astonishment of the physicians of that time, who saw this as a new, possibly easy, way of eradicating the diseases by exterminating the vectors. For some years, DDT and other then new insecticides achieved great improvements, but subsequently serious setbacks emerged: insecticide-resistance and anxiety about toxicity to man and animals. In the past twenty years, serious efforts have been made tofind alternatives, with varying degrees of success.

Book Description
Recent research on skin immunity and the skin microbiome reveals the complexity of the skin and its importance in the development of immunity against arthropod-borne diseases. In diseases such as malaria, borreliosis, leishmaniasis, trypanosomiasis, etc., the skin interface has been shown as an essential site for pathogens to hide from the immune system, and as a potential site of persistence. Only very few vaccines have been successfully developed so far against these diseases, likely because of an insufficient understanding on the development of skin immunity against pathogens. Skin and Arthropod Vectors expands our knowledge on the role of the skin interface during the transmission of arthropod-borne diseases and particularly its immunity. This work may support researchers who strive for developing more efficient diagnostic tools and vaccines. It also gives scientists and advanced students working in related areas a better insight on how humans and animals are attractive to arthropods to develop better repellents, or to set up transgenic arthropods. Offers the only compilation of research focusing on both the skin interface and arthropod vectors, with contributions from international experts Advances research in the effort toward generating more effective diagnostic tools and vaccines focusing on the skin interface Can also serve as supplemental material for dermatology lectures or specialized lectures on medical entomology and skin immunity

Book Description
Surprising though it seems, the world faces almost as great a threat today from arthropod-borne diseases as it did in the heady days of the 1950s when global eradication of such diseases by eliminating their vectors with synthetic insecticides, particularly DDT, seemed a real possibility. Malaria, for example, still causes tremendous morbidity and mortality throughout the world, especially in Africa. Knowledge of the biology of insect and arachnid disease vectors is arguably more important now than it has ever been. Biological research directed at the development of better methods of control becomes even more important in the light of the partial failure of many control schemes that are based on insecticide- although not all is gloom, since basic biological studies have contributed enormously to the outstanding success of international control programmes such as the vast Onchocerciasis Control Programme in West Africa. It is a sine qua non for proper understanding of the epidemiology and successful vector control of any human disease transmitted by an arthropod that all concerned with the problem - medical entomologist, parasitologist, field technician - have a good basic understanding of the arthropod's biology. Knowledge will be needed not only of its direct relationship to any parasite or pathogen that it transmits but also of its structure, its life history and its behaviour - in short, its natural history. Above all, it will be necessary to be sure that it is correctly identified.

Book Description
Blood-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.

Book Description
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.

Book Description
Biological Transmission of Disease Agents covers the proceedings of a 1960 symposium on Biological Transmission of Disease Agents, held in conjunction with the Annual Meeting of the Entomological Society of America in Atlantic City, New Jersey. This book discusses methods, approaches, and problems that contribute to the progress in basic and applied research in biological transmission. This compilation is organized into two major parts encompassing 13 chapters that cover agents of plant, animal, and human diseases. The first part of the book deals with the status and significant advances of plant viruses, and the mechanical and non-mechanical transmissions and nematode vectors of these viruses. The second part starts with a discussion on viral agents known to be mosquito-borne, their importance in animal and human disease causation, as well as the several types of biological cycles involved in their transmission. The following chapters describe groups of diseases caused by transmission of sandflies, tabanids, Tsetse-borne insects, mites, ticks, and helminths. The concluding chapter presents ways of suppressing the vectors that cause diseases, such as malaria, typhus, filariasis, dysentery, trypanosomiasis, and dengue. The book appeals to students of entomology, plant pathology, human and veterinary medicine, virology, zoology, microbiology, and other branches of biology.

This book attempts to bring together a broad array of molecular techniques and approaches currently used in insect pathology. It is divided into four parts: (i) identification and diagnostics; (ii) evolutionary relationships and genetics; (iii) host-pathogen interactions; and (iv) genomics and genetic engineering. Sixteen chapters have been written by leading researchers in the field which provide comprehensive and up-to-date information on each part.

Book Description
Despite great advances in public health worldwide, insect vector-borne infectious diseases remain a leading cause of morbidity and mortality. Diseases that are transmitted by arthropods such as mosquitoes, sand flies, fleas, and ticks affect hundreds of millions of people and account for nearly three million deaths all over the world. In the past there was very little hope of controlling the epidemics caused by these diseases, but modern advancements in science and technology are providing a variety of ways in which these diseases can be handled. Clearly, the process of transmission of an infectious disease is a nonlinear (not necessarily linear) dynamic process which can be understood only by appropriately quantifying the vital parameters that govern these dynamics.
