The Ecology Of Fungal Entomopathogens

Understanding of the ecology of fungal entomopathogens has vastly increased since the early 1800’s, but remains challenging. The often complex interactions between pathogen and host are being unravelled through eloquent research and the importance of the often subtle interactions, in determining the success or failure of biological control, cannot be underplayed. The realm of ecology is vast and deciphering insect-fungal pathogen interactions within an ecological context will take us on voyages beyond our imagination. This book brings together the work of renowned scientists to provide a synthesis of recent research on the ecology of fungal entomopathogens exploring host-pathogen dynamics from the context of biological control and beyond. Dr. Helen Roy leads zoological research in the Biological Records Centre at the NERC Centre for Ecology & Hydrology, UK. The focus of her research is insect community interactions with particular emphasis on the effects of environmental change. She has been working on the ecological interactions between fungal entomopathogens and their hosts for 15 years; this continues to be a source of fascination. She has been an associate editor of BioControl since 2006. Dr. Dave Chandler is an insect pathologist at the University of Warwick, UK. He has studied entomopathogenic fungi for just over 20 years. He has particular interests in entomopathogenic fungi as biocontrol agents of horticultural crops, fungal physiology and ecology, and the pathogens of honeybees. Dr. Mark Goettel is an insect pathologist at the Lethbridge Research Centre of Agriculture & Agri-Food Canada, specializing in the development of fungal entomopathogens as microbial control agents of insects. In addition to this research, he has been extensively involved in the review and revision of the regulations for registration of microbial control agents and has addressed regulatory and safety issues at the international level. He is currently President of the Society for Invertebrate Pathology and has been Editor-in-Chief of Biocontrol Science & Technology since 2000. Dr. Judith K. Pell heads the Insect Pathology Group in the Department for Plant and Invertebrate Ecology at Rothamsted Research, UK. She leads research on the ecology of fungal entomopathogens, to elucidate their role in population regulation and community structure and to inform biological control strategies. Specifically: intraguild interactions; the relationships between guild diversity, habitat diversity and ecosystem function; pathogen-induced host behavioural change. Dr. Eric Wajnberg is a population biologist specialising in behavioural ecology, statistical modelling and population genetics. He is also an expert in biological control, with more than 20 years experience of working with insect parasitoids. He has been the Editor in Chief of BioControl since 2006. Dr. Fernando E. Vega is an entomologist with the United States Department of Agriculture, Agricultural Research Service, in Beltsville, Maryland, USA. He conducts research on biological methods to control the coffee berry borer, the most important insect pest of coffee throughout the world. He is co-editor, with Meredith Blackwell, of Insect-Fungal Associations: Ecology and Evolution, published by Oxford University Press in 2005, and serves as an Editorial Board Member for Fungal Ecology.

There is an increasing interest in using fungi as bio control agents for insect pests in agricultural systems, and also a growing interest in the basic biology of insect-fungal associations from the perspective of parasitism, symbiosis and infection. This title covers topics in this field, incorporating new molecular techniques wherever possible.

Biological insecticides are competing more and more with traditional chemical pesticides. A successful application of natural pathogens requires a better understanding of both fungal and insect ecology and physiology. This Atlas provides a comprehensive overview of these fields and includes the taxonomy of those species of fungi which are proven pathogens. Biotechnological methods for the genetic modification of these natural pathogens resulting in further optimization and the advantages of biological control are discussed.

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.

Discusses the role of endophytes in food security, forestry and health. It outlines their general biology, spanning theory to practice.

Of the nearly one million known species of insects, about 15,000 species are considered pests and about 300 require some form of control. Fortunately, most insect pests have pathogenic microorganisms associated with them. There are two aspects of economic problems caused by insects.One concerns the loss of production that results from damage to crops and to the health of human and domestic animals, the other concerns the cost of attempt to prevent or control such production loses. At the same time with increasing agriculture, insects become more and more important competitors of human food damaging or even destroyingthe crops. Mosquitoes and black flies are a constant threat to health and comfort, yet the chemical pesticides used to control them have created serious ecological problems. Environmental and health concerns about the application of chemical insecticides to reduce large-scale insect pest infestations have led to renewed interest in the development of microbial agents for incorporation into integrated pest management strategies for the control of acridids.

Fungi are associated with a wide variety of other organisms. Ecologist Peter Price has said, “mutualism facilitates adaptive radiation,” and many biologists attribute Earth’s great fungal diversity to such associations. The 3rd edition of The Mycota, Vol. 9: Fungal Associations, has been revised to provide entirely new coverage of fungi and associated organisms in fourteen informative discussions that take advantage of today’s large public databases and modern molecular and data analysis methods. The editors have a keen interest in fungal associations in their own research, and their perspectives from different generations have resulted in an interesting treatment of the subject. Fungal Associations includes updates of classic topics, but also introduces less frequently discussed associations and broader reflections on the nature of fungi and their associates. The volume begins with a look at more than a billion years of fungal evolution and associations through the lens of immunology. Can fungi involved in obligate symbioses be cultivated apart from the host? Genomes help to answer the question. The ultimate intimacy between fungi and certain unrelated organisms has resulted in DNA exchange that can be traced in extant genomes. Fungi and bacteria use volatile compounds to lure participants into interactions. Some viruses modify the phenotype of their fungal hosts and affect host fitness. Details of interactions between classical examples of fungus—plant symbioses (lichens, several types of mycorrhizae, and toxic endophytes) benefit from advanced microscopic and molecular techniques. Discussions of fungi associated with insects (entomopathogens, a Drosophila model to study entomopathogens), nematode-trapping fungi and their prey, and a group of termite-associated fungi that produce secondary metabolites with potential uses as pharmaceuticals, complete the volume. Fungal Associations is a well-illustrated, thought-provoking resource for specialists and generalists, including researchers, lecturers, and students interested in ecology, evolution, microbiology, and mycology. The volume would be an excellent text for a seminar course for advanced undergraduate or graduate students.
