Single confocal sections and spike frequency histograms (spikes s⁻¹) of physiologically and morphologically characterized PNs in the codling moth male AL. (a) Synergistic responses of a PN innervating the Cu to blends of codlemone with pear ester and β-farnesene. (b) Synergistic responses of a multi-glomerular PN, innervating the satellite glomeruli 20 and 37, to blends of codlemone with pear ester and butyl hexanoate. (c) Suppressive responses of a PN innervating the glomerulus 14, to a blend of codlemone and (E)-β-farnesene at different blend ratios. Confocal sections: entrance of the antennal nerve (arrowheads), depth from anterior side of the AL (Z), scale bars (50 µm), glomeruli numbers correspond to the three-dimension AL atlas [21]. Histograms: stimulus period (bars, 500 ms).
