Spletchemical analyses citral was identified exclusively in the foragers’ mandibular glands, which disproves its supposed role as a trail pheromone. The labial glands contained a series of terpene- and wax type esters, with farnesyl but-anoate as major constituent. We, therefore, postulate that the trail pheromone of G. mombuca is composed of a blend Spletchemical analyses citral was identified exclusively in the foragers’ mandibular glands, which disproves its supposed role as a trail pheromone.
