The relationship between a trail pheromone and division of labor in Lasius japonicus
(Hiroshima Univ.)
oMai Takatsu, Shunsuke Izumi
Worker ants of Lasius japonicus consist of “outside workers" that forage outside the nest and “inside workers" that care for the pupas in the nest. In this study, we investigated compounds that regulate the division of labor in worker ants. Mass spectrometry imaging and GC-MS measurements revealed that 2-tridecanone was detected in both worker ants, while 2-tridecanol was detected only in inside worker. As a behavioral experiment, 2-tridecanol was applied to outside workers and observed their behavior. 2-tridecanol applied outside workers remained in the nest and behaved like inside workers. These results suggested that the division of labor in worker ants may be regulated by 2-tridecanol.
