Intenational behavioural ecologist and sociobiologist Prof Raghavendra Gadagkar of the Centre for Ecological Studies at the Indian Institute of Science in Bagalore, India, presented a Centenary lecture at the University on 15 July 2008.

The internationally acclaimed scientist is fascinated by the origin and evolution of cooperation in social insects and presented aspects of his research on the social structure of the species Ropalidia marginata (wasps).

Gadagkar presented his subject, entitled: “Interrogating an insect society”, by way of a series of questions: “Why are ants, bees and wasps social?” and “What are the evolutionary advantages of social life over solitary life?” His answers were formulated in response to the questions: “How are they social?” and “What are the mechanisms of social organization, communication, division of labour, etc?”

His fascinating presentation explained the dominance hierarchy in the insect colonies, the behaviour of the queen and the phenomenon of a potential queen, or heir designate.
