| Abstract: | The Dufour gland secretion consists of a solution of volatile oxygenated compounds in a mixture of higher hydrocarbons and sesquiterpenoid alkenes. Methanol, butenone, 2-methylpropanal, and 1-butanol have now been identified as the remaining major volatile components. These substances have no strong behavioural effect upon ants, nor do they induce trail following behaviour. The principal activity of the Dufour gland can be traced to the three more abundant volatile components, ethanal, acetone, and butanone, together with the minor component ethanol. |
