has lost the queen caste and instead, reproduction is undertaken by a single, mated worker, termed a gamergate (Ware et al. 1990; Peeters 1991). Mandibular glands of workers contain three types of pyrazines which, in a study based on two colonies, were found to occur in smaller quantities and in different proportions in the gamergate compared with the mated workers (Jones et al. 1998).
