Fig 5.

Representative TIC of cuticular lipids (A) from five geographic morphs of A. pisum (B). Wingless adults were used for SPME detection with 7 μm PDMS fiber. Colored numbers above the peaks indicate their rank of peak area for the respective morph (see quantized data in Table 4). ‘×4’ or ‘×8’ in panel (A) indicates that peaks ahead are four or eight times higher than their actual sizes. Peaks with gray shadows indicate the three main cuticular aldehydes. Scale bar in panel (B) is 1 mm.
