Insect Fungus Interactions

The first and only book to summarize this fascinating topic. This symposium volume reviews the current state of knowledge in four principal areas: mycophagy, mutualism, insect spread of plant fungal disease, and insect mycopathology.

Appendix contains summary of mycophagous interactions.

Although many insects successfully live in dangerous environments exposed to diverse communities of microbes, they are often exploited and killed by specialist pathogens. In the process of the co-evolution of insects and entomopathogenic microorganisms, they develop various adaptive systems that determine the sustainable existence of dynamic host–parasite interactions at both the organismic and population levels.

Insects and fungi have a shared history of association in common habitats where together they endure similar environmental conditions, but only recently have mycologists and entomologists recognized and had the techniques to study the intricacies of some of the associations. This new volume covers "seven wonders of the insect-fungus world" for which exciting new results have become available, often due to the use of new methods that include phylogenetic analysis and development of molecular markers. Eleven chapters of the volume are presented in two sections, "Fungi that act against insects" and "Fungi mutualistic with insects" that cover a number of major themes. Examples of necrotrophic parasites of insects are discussed, not only for biological control potential, but also as organisms with population structure and complex multipartite interactions; a beneficial role for symptomless endophytes in broad-leafed plants is proposed; biotrophic fungal parasites with reduced morphologies are placed among relatives using phylogenetic methods; complex methods of fungal spore dispersal include interactions with one or more arthropods; the farming behavior of New World attine ants is compared with that of humans and the Old World fungus-growing termites; certain mycophagous insects use fungi as a sole nutritional resource; and other insects obtain nutritional supplements from yeasts. Insects involved in fungal associations include--but are not limited to--members of the Coleoptera, Diptera, Homoptera, Hymenoptera, and Isoptera. The fungi involved in interactions with insects may be clustered taxonomically, as is the case for Ascomycetes in the Hypocreales (e.g., Beauveria, Metarhizium, Fusarium), ambrosia fungi in the genera ophiostoma and ceratocystis and their asexual relatives, Laboulbeniomycetes, Saccharomycetes, and the more basal Microsporidia. Other groups, however, have only occasional members (e.g., mushrooms cultivated by attine ants and termites) in such associations. The chapters included in this volume constitute a modern crash course in the study of insect-fungus associations.

This volume offers extensive information on insect life in dying and dead wood. Written and reviewed by leading experts from around the world, the twenty-five chapters included here provide the most global coverage possible and specifically address less-studied taxa and topics. An overarching goal of this work is to unite literature that has become fragmented along taxonomic and geographic lines. A particular effort was made to recognize the dominant roles that social insects (e.g., termites, ants and passalid beetles) play in saproxylic assemblages in many parts of the world without overlooking the non-social members of these communities. The book is divided into four parts: · Part I “Diversity” includes chapters addressing the major orders of saproxylic insects (Coleoptera, Diptera, Hymenoptera, Hemiptera, Lepidoptera and Blattodea), broadly organized in decreasing order of estimated global saproxylic diversity. In addition to order-level treatments, some chapters in this part discuss groups of particular interest, including pollinators, hymenopteran parasitoids, ants, stag and passalid beetles, and wood-feeding termites. · Part II “Ecology” discusses insect-fungal and insect-insect interactions, nutritional ecology, dispersal, seasonality, and vertical stratification. · Part III “Conservation” focuses on the importance of primary forests for saproxylic insects, offers recommendations for conserving these organisms in managed forests, discusses the relationships between saproxylic insects and fire, and addresses the value of tree hollows and highly-decomposed wood for saproxylic insects. Utilization of non-native wood by saproxylic insects and the suitability of urban environments for these organisms are also covered. · Lastly, Part IV “Methodological Advancements” highlights molecular tools for assessing saproxylic diversity. The book offers an accessible and insightful resource for natural historians of all kinds and will especially appeal to entomologists, ecologists, conservationists and foresters.

Although many insects successfully live in dangerous environments exposed to diverse communities of microbes, they are often exploited and killed by specialist pathogens. In the process of the co-evolution of insects and entomopathogenic microorganisms, they develop various adaptive systems that determine the sustainable existence of dynamic host-parasite interactions at both the organismic and population levels.

The object of this volume is to draw attention to the wide range of associations between fungi and living organisms, particularly animals and plants, where there are indications that coevolution has been a major factor in their development.
