Table 2 CHC profiles of 5- and 10-day old antibiotic-treated (Gmm^Wgm- = ampicillin; Gmm^Apo = tetracycline) and control male G. m. morsitans after mass- or individual rearing. Compounds are sorted by class (mono-, di-, and trimethyl-alkanes). Given are average relative amounts of CHCs (in percent) +/− standard deviation, as well as the total absolute amount of CHCs as determined by comparison with an internal standard.
