GC-MS chromatograms of volatiles collected from fermented banana. Numbered compounds produced EAD-responses in the antennae, proboscis, forelegs, midlegs, and labial palpi of Morpho helenor and Caligo telamonius (compound no. 13, propyl acetate, was determined using GS-FID). For compound names, see Table 2.
