Evolution, Function and Chemical Diversity of Queen Pheromones in Social Insects
Kašparová, Kateřina ; Hanus, Robert (advisor) ; Urbanová, Klára (referee)
Societies of eusocial insects are probably the most complex biological systems. Repeated independent evolution of eusocial organization in multiple insect lineages has typically led to an unprecedented ecological success of these insects. However, beside coordinated work activities and altruism, the eusocial societies are also characterized by a potential for conflict over reproduction, leading to the evolution of mechanisms that prevent this conflict and ensure the colony homeostasis. Though it has long been known that this role is mediated by Queen Pheromones, there is still an important knowledge gap between our understanding of the biological role of Queen Pheromones and their chemical identity, biosynthesis and perception. Although the first Queen Pheromone has been identified in the early 1960s, more intensive research in this area is the matter of the last decade. The best known Queen Pheromone is that of the honey bee, contrasting with the knowledge on other social Hymenoptera and termites. Elucidating the chemical nature of Queen Pheromones could help to a better understanding of the evolution of social insects, their life cycle and community organization. This thesis summarizes the knowledge about the evolution and chemistry of Queen Pheromones in social insects.
