Symposium 3: Molecular and hormonal signaling pathways in caste development and reproduction
Recent large-scale genomics projects, as well as specific studies on gene expression and hormonal regulation are revitalizing one of the oldest questions in social insect biology, that is, which are the proximate mechanisms that control and direct the development of caste phenotypes, their differential reproduction, and their division of labor. The aim of this symposium is to present novel approaches in an attempt to synthesize the emerging perspectives on developmental regulation and reproductive physiology.
