Chemical warfare between plants and their herbivores and pathogens was first brought to our attention by the publication 25 years ago of the paper by Fraenkel in Science.

This led, rather gradually, to a host of papers on plant-herbivore interactions. More or less at the same time, insect physiologists and ecologists were starting to realise the importance of chemical communi cation systems in...

The links between cognition, behaviour and affect are clearly made, and go beyond simple matters of food, weight and shape...this book is a valuable addition to the literature. Its blend of theory, empirical evidence,...
