Interaction of pheromones during food exploitation by the termite Schedorhinotermes lamanianus

摘要: . Chemical signals from secretions of different exocrine glands modulate a variety behavioural patterns in termite societies. These have multiple functions and may be interactive. During food exploitation workers the African Schedorhinotermes lamanianus (Isoptera: Rhinotermitidae) employ, on foraging trails, secretion sternal gland both for orientation recruitment to source. The labial gland, released onto by gnawing termites, stimulates additional gnaw at same site, thereby forming aggregations termites. An interaction between these two pheromones during is demonstrated first time. volatile signal inhibits dose-dependent manner non-volatile, highly persistent, gland. development inhibited established ones are dissolved. Behavioural evidence perception olfactory neurones non-volatile gustatory antennae given. as basis distinct commuting zones source, means dynamic regulation exploitation, discussed.
