Analysis of the extracts of male ants of monomorium minimum and Monomorium ebeninum by GC-MS and GC-FTIR revealed the presence of tyramides 2 and 4c, for which the structures were established by comparison with synthetic samples. These compounds and their analogues 1 and 3 were also found in males of other Monomorium species, males of Myrmicaria opaciventris, and males of several Solenopsis (Diplorhoptrum) species. Vapor-phase FTIR spectra revealed critically important structural cities to two of the tyramides, which had methyl branching in the tyramide acyl moiety. Tyramide 4c exhibited a strong intramolecular amide NI-I hydrogen bond where an alpha-keto group was deduced to be present in the acyl moiety and also showed the overlap of this ketone group frequency with that of the amide nu(C=O). The biological function of these compounds is uncertain: however, their role in ant-mating behavior may be suggested by a large body of evidence.

The present invention relates generally to an ant attractant, aggregant or arrestant formulation comprising the ant attractant bicyclic tertiary alcohol compound, geosmin (1,2,7,7-tetramethyl-2-norborneol) and ant repellent formulation comprising the ant repelling bicyclic tertiary alcohol compound, 2-methylisoborneol (2-MIB). It furthermore relates to a system and method for attracting ants by geosmin (l,2,7,7-tetramethyl-2-norborneol) and/or repelling ants by 2-methylisoborneol (2-MIB).
