Literature Review Of Chalkbrood A Fungal Disease Of Honeybees

Chalk brood of honeybees (Apis mellifera) is caused by the fungus Ascosphaera apis. It was first diagnosed in Australia in 1993 and is now endemic in most areas of Australia. Although chalk brood is not usually fatal to honeybee colonies it can cause substantial production losses The aim of this study was firstly to review the literature on chalk brood so as to distil into one document the various control measures that have been used to reduce the economic losses caused by this disease. Secondly, the aim was to identify areas that could be investigated so as to expedite the development of control strategies to minimise the economic losses caused by chalk brood.

Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Insect Pathology is designed for a broad spectrum of readers. Is should be useful to students, lecturers, and researchers requiring information about the principles in insect pathology and the biology of pathogens. It should serve as a resource for specialists to learn about other insect pathogen systems, for generalists to become aware of advances in insect pathology, and for scientists and students, beginning or otherwise, interested in learning about insect pathology. This book was originally intended to update the 1949 test by E. A. Steinhaus entitled Principles of Insect Pathology. The purpose for this book was twofold: To serve (1) as a text for an insect pathology and/or biological control class and (2) as a comprehensive reference source. Because this book summarizes much of the available information, its usefulness as a textbook for an insect pathology class is apparent. Although the literature citations are extensive, they are far from complete. The literature in insect pathology is voluminous and for the past decade has been expanding at an almost exponential rate. A complete review of the literature is beyond the scope of the book, and an omission of a reference does not preclude its importance. Our citations, however, should serve as a good starting point for those who wish to obtain further information. We have attempted to cover equally all subdisciplines, but shortcomings are unavoidable. For these, we take full responsibility.

Control of diseases and pests of honey bees is one of most challenging tasks in improving quality of honey and honey bee by-products, especially for the beekeepers in developing countries. This publication describes common diseases and pests of honey bees and their importance and provides a practical guide to the basic technology available to beekeepers for their control and prevention.

key pollinators honey bees, have been evolved for million years along with flowering plants. Asia is rich with species diversity and the bees are known to play vital roles in maintaining the the local fauna and sustain the agricultural crops to secure food sources for human consumption in the region, where the population continue to grow. Southeast Asia is regarded as a hot spot for scientists to study ecological interaction and co-evolution between hosts and parasites 9n different species of honey bees. The most serious and widespread bee pathogens and parasites today in the European honey bee are parasitic mites. nosema, kashmir bee virus which may have originated from Asian honey bees in South East Asia, More information on Asian honey bee health can also reflect the future threat in European honey bee worldwide especially when the global warming and fast transportation allow the prevalence and dissemination of tropics pathogens and parasites. This book aims to provide the current bee health status of honey bees in Asia which are now under emerging pressures from natural causes and human activities in modern society of globalization. Symbiotic relationships between living organisms and honey bees are also described

Fungal growths affect both human and animal well-being. Many natural pathogens of laboratory animals alter host physiology, rendering the host unsuitable for experimental uses. While the number and prevalence of few pathogens have declined considerably, many still turn up in laboratory animals and represent unwanted variables in research. Investigators using laboratory animals in biomedical experimentation should be aware of the profound effects that many of these agents can have on research. What does the future hold regarding the natural pathogens of laboratory animals? The selection of an animal model must carefully address issues of the type of human disease to mimic, the parameters to follow, and the collection of the appropriate data to answer those questions being asked. Overall, animal models of fungal infection will continue to deepen our understanding of how these infections occur. This book provides a valuable source of information to biological and biomedical scientists and to clinical and doctoral researchers working in the area of fungal infections and diseases of laboratory animal species.
