Overview

Literature currently available on the population dynamics of insect herbivores tends to favour a topdown regulation of abundance, owing much to the action of natural enemies. This unique volume challenges this paradigm and shows that tree-dwelling species of aphids, through competition for resources, regulate their own abundance.

The biology of tree-dwelling aphids - particularly their adaptation to the seasonal development of their host plants - is examined. When host plant quality is favourable, aphids, by telescoping generations, can achieve prodigious rates of increase that their natural enemies are unable to match.

Using analyses from long-term population census and experiments, this book is designed to introduce students and research workers to insect herbivore-host dynamics using the interaction between aphids and trees as a model.
