Article Synopsis
- Miniaturized queens, or microgynes, are a rare reproductive strategy among ants, serving roles like short-distance dispersal and adaptation to polygyny and parasitism.
- In a study of two Ectatomminae species in Mexico, researchers found that microgynes and macrogynes are the same species, primarily monogynous with daughters usually remaining in their mother's nest.
- The study indicated that while nests can appear polygynous, they are often led by macrogyne queens, with factors like nest density and environment influencing the occurrence of microgynes.
Background: In honey bee colony, the brood is able to manipulate and chemically control the workers in order to sustain their own development. A brood ester pheromone produced primarily by old larvae (4 and 5 days old larvae) was first identified as acting as a contact pheromone with specific effects on nurses in the colony. More recently a new volatile brood pheromone has been identified: E-β-ocimene, which partially inhibits ovary development in workers.
