Biology Of Termites

Biology of Termites, a Modern Synthesis brings together the major advances in termite biology, phylogenetics, social evolution and biogeography. In this new volume, David Bignell, Yves Roisin and Nathan Lo have brought together leading experts on termite taxonomy, behaviour, genetics, caste differentiation, physiology, microbiology, mound architecture, biogeography and control. Very strong evolutionary and developmental themes run through the individual chapters, fed by new data streams from molecular sequencing, and for the first time it is possible to compare the social organisation of termites with that of the social Hymenoptera, focusing on caste determination, population genetics, cooperative behaviour, nest hygiene and symbioses with microorganisms. New chapters have been added on termite pheromones, termites as pests of agriculture and on destructive invasive species.

Biology of Termites, Volume I presents the anatomical, physiological, biochemical, and behavioral laboratory and field studies of termite species. Although termites have been associated mainly with damage, only less than 10% of the species have actually been recorded as pests, obscuring their important ecological role in the breakdown of vegetative matter and their variety and complexity of structure, physiology, social behavior, caste differentiation and regulation, and other aspects of their biology. After briefly describing the social organization, classification, and research history of termites, the book discusses the external morphology of these species and the similarities and differences between the various groups and the different castes. The subsequent chapters cover the internal anatomy of termites, including their digestive physiology, exocrine and endocrine glands, reproductive and nervous systems, and sense organs. Other chapters deal with the social behavior and communication in the termites and the termite colonizing flights and associated activities. The book also examines caste differentiation in the three lower termite families, namely, Hodotermitidae, Kalotermitidae, and Rhinotermitidae. This volume includes discussions on the rearing, feeding, and biochemistry of termites; the radioisotopes for feeding studies; and the moisture requirements for termite survival. The concluding chapters deal with the introduction or interception of termites by humans and their association with fungi, as well as the relationships of termite hosts with termitophiles. Termite biologists, zoologists, botanists, ecologists, behaviorists, biochemists, endocrinologists, and economic entomologists will find this volume invaluable.

The book is a new compendium in which leading termite scientists review the advances of the last 30 years in our understanding of phylogeny, fossil records, relationships with cockroaches, social evolution, nesting, behaviour, mutualisms with archaea, protists, bacteria and fungi, nutrition, energy metabolism,population and community ecology, soil conditioning, greenhouse gas production and pest status.

This Volume comprises 12 chapters in an attempt to bring available information on biology, social behavour and economic importance of termites. Chapters in this book dealing with termites identification provide a review on most updated information of their systematics. Ecologically, termites interact with living and non-living surroundings and deliver a wide range of behaviors. In a separate chapter termites ecology is examined and explored. Termites depend on their gut microbes for digestion of complex polysaccharides of wood into simpler molecules. Information provided on termite gut microbiome and lignocellulose degradation constitutes an important contribution. Termite biology and social behaviour have been addressed comprehensively. Trail pheromones are responsible for the orientation and recruitment of nestmates to the food sources. Once arriving at a potential food source, termites assess its quality using a different set of cues. A separate chapter on trail pheromones, cues used during foraging and food assessment, with preferences for foraging sites, contributes a wealth of information. Emphasis has been given on reviewing ecological benefits of termites in other chapters. The information with respect to termite species as an edible insect and the overall role it plays in food and nutrition security in Africa is quite informative. A separate chapter dealing with importance of termites and termitaria in mineral exploration constitutes a significant step in addressing the economic importance of this insect group.

This text provides a scientific introduction to termites, including their behaviour, pest status and control.

This is the first work to focus on microbes in gut systems of soil animals. Beginning with an overview of the biology of soil invertebrates, the text turns to the gut microbiota of termites, which are important soil processors in tropical and subtropical regions. Coverage extends to intestinal microbiota of such other litter decomposers as earthworms, springtails, millipedes, and woodlice. Thoroughly illustrated, including color photographs.

Termites are believed to be the oldest eusocial insects and their morpho-physiologically distinct castes are called reproductives, workers, soldiers and immature forms. Termites are called xylophages or wood-decaying insects but can also feed on a variety of organic materials, including grasses, litter, humus, and components of the soil, such as hydrolysable peptides and polyphenolic compounds. These specialized feeding habits of termites are linked to their digestive apparatus and allow them to act as primary consumers and decomposers (herbivores and detritivores). In this book, chapter one discusses the connections between digestive processes of termites and their feeding habits and ecological role. In chapter two, the functional morphology of the digestive tube of ten species belonging to seven genera of neotropical Termitinae is analyzed, with the aim of characterizing and comparing the configuration of individuals from different castes. The final chapter in this book discusses the physical phenomenon which causes the absence of mites at high altitudes in Europe. The aim of studies conducted in chapter three, is to systematically review the relationship between allergen exposure in Europe and altitude-related characteristics.
