Abstract

Social insects such as ants, bees, wasps and termites live in colonies consisting of one or a small number of reproductive kings and queens and a large number of non-reproductive workers. On the one hand such reproductive caste differentiation is an evolutionary paradox. But on the other hand, it is also a unique example of the social regulation of reproduction. In this talk I will focus on the latter phenomenon and illustrate our attempts to understand the regulation of reproduction in the tropical primitively eusocial wasp Ropalidia marginata. This model system is especially interesting because the regulation of reproduction is mediated by behavioural interactions and is rapidly reversible. It is also interesting because such regulation appears to happen with surprisingly little overt conflict.

Raghavendra is Year of Science Chair ProfProf. Raghavendra Gadagkaressor at the Centre for Ecological Sciences, Indian Institute of Science. During the past 25 years he has established an active school of research in the area of Animal Behaviour, Ecology and Evolution. The origin and evolution of cooperation in animals, especially in social insects, such as ants, bees and wasps, is a major goal of his research. By identifying and utilizing crucial elements in India’s biodiversity, he has added a special Indian flavour to his research.
