Characterization of Queen Supergene Pheromone in the Red Imported Fire Ant Using Worker Discrimination Assays.

Journal of chemical ecology - 1 Feb 2022

Zeng Haolin, Millar Jocelyn G, Chen Li, Keller Laurent, Ross Kenneth G

Abstract excerpt

Ants use chemical signals to communicate for various purposes related to colony function. Social organization in the red imported fire ant, Solenopsis invicta, is determined by the Sb supergene, with colonies of the monogyne (single-queen) form lacking the element and colonies of the polygyne (multiple-queen) form possessing it. Polygyne workers accept new reproductive queens in their nest, but only those...
