A new study reveals that foreign queen ants trick host colonies into killing their own queen using chemical mimicry and formic acid, marking the first known case of matricide induced by a parasite.
Scientists have discovered a new form of matricide in ant colonies where foreign queen ants infiltrate host colonies by mimicking their chemical scent, then use a substance—likely formic acid—to trigger worker ants to kill their own queen.
This deceptive strategy, observed in species like Lasius orientalis and umbratus, marks the first documented case of a parasite causing offspring to murder their mother.
Once the host queen is eliminated, the invader takes over, with workers accepting her as the new ruler and raising her offspring.
The behavior, published in Current Biology, reveals a sophisticated use of chemical manipulation never before seen in any animal species and highlights how social insects can be exploited through their reliance on scent-based communication.
Un nuevo estudio revela que las hormigas reinas extranjeras engañan a las colonias anfitrionas para matar a su propia reina usando imitación química y ácido fórmico, marcando el primer caso conocido de matricidio inducido por un parásito.
