Figure 5: Eleven chemicals in fermented banana volatiles identified here, produced EAD-responses in olfactory organs of Morpho helenor. (a) Proboscis. (b) Foreleg, antenna, and midleg of Morpho helenor and the same organs of Caligo telamonius produced similar EAD-responses. (1) 2-Methylpropyl acetate. (2) Ethyl butanoate. (3) Butyl acetate. (4) 1-Methylbutyl acetate. (5) 3-Methylbutyl acetate. (6) Isobutyl isobutyrate. (7) Butyl butanoate. (8) Hexyl acetate. (9) 1-Methylhexyl acetate. (10) Butyl 3-methylbutanoate. (11) Pentyl pentanoate.
