Symposium 17: Evolution and development in caste differentiation of termites
Termites are one of the major groups of eusocial insects, possessing castes that accomplish sophisticated social behavior through division of labor. However, the evolutionary origins of various castes, including workers, soldiers and reproductives is a subject of contention. In this symposium, several termitologists will give talks on the evolution of termite castes in terms of life history strategies, developmental regulation and molecular basis of caste differentiation. The aim of this symposium is to clarify the questions that will lead to an understanding of the evolution of termite societies.
