... is responsible for multiple distinct roles such as nestmate recognition and signalling fertility status. This study investigates these two signalling roles of the hydrocarbon profile in the trap-jaw ant Odontomachus brunneus . We demonstrate that the cuticular hydrocarbon profile is highly variable across...

...Gissella M. Vásquez; Coby Schal; Jules Silverman SUMMARY In social insects, individuals typically recognize and behave aggressively towards alien conspecifics, thereby maintaining colony integrity. This is presumably achieved via a nestmate recognition system in which cuticular compounds, usually...

... chemical cues play a major role in discrimination between nestmates and non-nestmates, classical bioassays based on aggressive behaviour were not particularly effective in disentangling chemical perception and behavioural components of nestmate recognition by means of categorical variables. We therefore...

... behaviour according to their particular role in the nestmate recognition process. The thorax surface temperature was on average higher and more variable in the examinees (36.1 °C, S.D.=4.14, N =1545, 303 bees) than in the guards (34.0 °C, S.D.=2.00, N =1681, 772 bees). During thorough examinations lasting...
