In the clonal raider ant (Ooceraea biroi), workers in a colony alternate between caring for larvae and laying eggs in a coordinated cycle. Researchers at the Max Planck Institute for Chemical Ecology in Jena have discovered how this cycle is controlled. The larvae emit a specific chemical signal that suppresses the fertility of adult workers. The team identified a previously unknown volatile compound produced exclusively by larvae: methyl-3-ethyl-2-hydroxy-4-methylpentanoate (MEHMP). Exposure to synthetic MEHMP drastically reduced egg-laying in adult ants—the same reaction observed in the presence of larvae. Thus, for the first time, the research team was able to chemically characterize a brood pheromone in ants. The study shows that larvae can control their parents’ reproductive behavior using chemical signals. Therefore, larvae are not merely passive recipients of parental care; they also play an active role in shaping the reproductive dynamics of their colonies.
