In this time of edited volumes when the list of individual contributors may reach double figures, it is appropriate to question the usefulness of a volume, with such a broad scope, by a single author. The answer is simple. For years he has believed that the rather sharp distinction between fundamental and applied aspects of this discipline, has ill-served the significance of each; and has diminished the incidence of fruitful synergies. Yet the need for these was never greater, and this case may be developed by a single author with experience of each aspect. The inclusion of a Chapter on Genetic Engineering may raise some doubts, but it is enabled by the chosen title "Chemoreception," as distinct from Chemoperception: the latter implies detection of a chemical, followed by a behavioural response. But the former broader category subsumes Chemoperception and allows for the reception of a chemical toxin so potent as to prelude a behavioural or physiological response, other than death. Accordingly, chemical toxins are a legitimate inclusion. In which event, their delivery through a GM plant is as appropriate for study as their application in a spray.

Recent research has added much to our knowledge of the nature and significance of chemoreception in insects. This text deals with both pure and applied aspects at the ecological level, and goes on to discuss the mechanisms by which insects detect and respond to chemicals at the molecular level. Throughout the text reference is made to appropriate techniques in both field and laboratory situations in order to provide an insight into the means of investigating the subject and to indicate the areas of likely future advances. Plant-insect interactions are considered in terms of plant chemical defences and of the co-evolved insect response to these. The role of pheromones is described with an account of the factors governing their synthesis and secretion. A chapter on pheromone gland morphology is also included. The electrophysiological approach is described and also the novel use of biochemical techniques to ascertain the mode of action of plant and insect-produced chemicals. Practical applications reported include the use of natural toxins in plant protections and the exploitation of pest-resistant crop varieties. This book should be of interest to fundamental and applied entomologists, agronomists, chemists and workers in the fields of chemoreception and chemical ecology.
