Cuticular Hydrocarbon Content that Affects Male Mate Preference of Drosophila melanogaster from West Africa

Figure 3

Mirrored gas chromatograms of n-hexane extracts of TW1 and Mel6 females. C₂₂–C₃₀ standard marker positions are indicated between the chromatograms. Each peak corresponds to hydrocarbon compound whose identity could be inferred from the previous studies [28, 29]. The peaks indicating qualitative differences (presence/absence or extreme high/low) between the two strains are marked by numbers. The inferred components for the peaks: peak #1: 7:C23; #2: C23; #3: 7,11:C25; #4: 5:C25; #5: 7,11:C27; #6: 5,9:C27 (+2-methylhexacosane).
