Summary

Story summary

A study published in Current Biology identifies a unique chemical manipulation by parasitic ant queens that leads to host-queen assassination and colony takeover.
Researchers observed Lasius orientalis and umbratus infiltrating colonies, disguising their scent, and inciting worker ants to attack their own queen with formic acid.
The findings reveal complex social dynamics and chemical communication, advancing understanding of social parasitism.
