Insect-Fungal Associations


Book Description

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.




Insect-Fungal Associations


Book Description

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.




Fungus-Insect Relationships


Book Description

A significant addition to the field of fungus-insect relationships, this book presents an interesting array of approaches to the subject of evolutionary and ecological associations of insects and fungi, written by both mycologists and entomologists.The volume is indispensable as an introduction to modern approaches in the field, a reference on host associations, and a theoretical basis for future research.

Insect Symbiosis, Volume 3


Book Description

The associations between insects and microorganisms, while pervasive and of paramount ecological importance, have been relatively poorly understood. The third book in this set, Insect Symbiosis, Volume 3, complements the previous volumes in exploring this somewhat uncharted territory. Like its predecessors, Volume 3 illustrates how symbiosis resear




Insect-Fungus Interactions


Book Description

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.




Saproxylic Insects


Book Description

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.




Trichomycetes and Other Fungal Groups


Book Description

The book has been divided into two parts. Part I comprises review chapters on trichomycetes - including the history, taxonomy, phylogeny, biogeography ultrastructure, and physiology of trichomycetes. Part II comprises a composite of topics. It begins with two chapters on insect-fungus associations (ant pathogenic fungi and bark beetle galleries) fo




Systematics and Evolution


Book Description

Mycology, the study of fungi, originated as a subdiscipline of botany and was a des criptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgetf, Kniep and Lindegren are all associated with this early period of fungal genet ics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for biochemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.
