PREFACE
Plant-insect interactions virtually took ecology by storm, and have greatly helped in increasing our understanding of the evolutionary related processes involved in the regulation of insect populations on plants, and related biological parameters. The growing points of new knowledge that are emanating from these studies are being increasingly applied to agricultural ecology, restoration ecology and forestry. In Indian scenario, though the output has been restricted to plants of economic importance, plant-herbivore interaction as a core subject has the potential to make enormous contributions to our understanding of the complexities of agroecosystems of diverse origins. It is to that direction that the thematic aspect to this book is aimed at, and will serve its purpose if it can give a little nudge to that effect. Causal interactions in plant herbivory by insects so far have been viewed from the perspective of leaf chemistry rather than from the dynamic aspects of nutrients and phytochemicals. Many, otherwise important studies, have solely concentrated on relating the presence of insects or their absence, to specific plant compounds. The crucial elements in the causal pathway that attract insects to their host plants, stabilize their populations or even outlay them, have not always been evaluated from the perspective of evolutionary biology. I have tried to touch upon this aspect without totally

overlooking the more mundane aspects of managing obnoxious insects by the utilization of the very allelochemicals that the plants generate to defend themselves against the phytophages. To a purist an approach like this may appear spurious, but against the background of the complex insect and plant systems, following a narrow path of rectitude at times becomes difficult, and debatable as well. This book summarises some of the classical studies in insect herbivory with the objective to stimulate rather than seeking solutions to many a vexed problems in insect phytophagy. I have tried to avoid generalizations not always successfully though , because each species of insect and plant interacts in its own unique way. An appreciation of this uniqueness in germane to our understanding of the defence mechanisms of the plants and their flexibilities in relation to the distribution and abundance of the insects on plants. This book derives its inspiration from many classical studies in insect herbivory such as Insects on Plants Strong, Lawton and Southwood , and certainly is no substitute for them. Its purpose will be adequately served if it kindles the imagination of a new genre of ecologists and entomologists to
