Fig. 1.

Simultaneous response of flame ionization detector (FID) and male Pachnoda interrupta antennae (EAD) to volatile compounds collected from a abutilon and b sorghum. The upper traces in each figure represent the signal from the FID and the lower traces represent the signal from the EAD. The compounds collected from abutilon headspace extracts were identified as (Z)-3-hexen-1-ol (1), tetradecane (2), methyl salicylate (3), and methyl anthranilate (4), and in sorghum tridecane (5), (Z)-3-hexen-1-ol (1), 1-octen-3-ol (6), and 1-octanol (7)
