The Hymenoptera is one of the largest orders of terrestrial arthropods and comprises the sawflies, wasps, ants, bees and parasitic wasps. "Hymenoptera: Evolution, Biodiversity and Biological Control" examines the current state of all major areas of research for this important group of insects, including systematics, biological control, behaviour, ecology, and physiological interactions between parasitoids and hosts. The material in this volume originates from papers presented at the Fourth International Hymenoptera Conference held in Canberra, Australia in early 1999. This material has been extensively rewritten, refereed and edited; culminating in this authoritative and comprehensive collection of review and research papers on the Hymenoptera. The authors include many world-leading researchers in their respective fields, and this synthesis of their work will be a valuable resource for researchers and students of Hymenoptera, molecular systematics and insect ecology.
