Table 1: VOCs produced by _U. dermatestoiles_ and collected with CAR/PDMS fiber. values. Unlike the results in T1, when the sample was treated with T2, neither _cis_-verbenol, verbenone, and myrtenol monoterepnes nor phenol-like metabolites were detected. In general terms, _U. dermateoides_ under the four analysis conditions produced the same types of molecules: quinones, terpenes, and aliphatic alkenes. Moreover, as reported previously, methyl-1,4-benzzoquinone, ethyl-1,4-benzzoquinone, limonene, 1-tridecene, and 1-pentadecene were present under all four conditions. On the other hand, other secondary metabolites were identified that had not been previously reported for _U. dermateoides_. These results suggested the need to obtain essential oils under both stimulus conditions to obtain a broader vision of the metabolome of _U.
