| Abstract: | The volatile Dufour's gland components of Pogonomyrmex rugosus and P. barbatus have been examined and found to be hydrocarbons. Homologous families of alkanes from this gland consisted of normal hydrocarbons ranging from n-dodecane to n-pentadecane and three types of methyl-branched homologues of the general formula CnH2n+1CH(CH3)CmH2m+1, where n is 2, 4, or 5 and the sum of n and m is 10, 11, 12, or 13. The dimethyl-branched hydrocarbons 3,5-dimethyldodecane and 3,4-dimethyltridecane were also observed. |
